PIC16C62A-10I/SO

PIC16C62A-10I/SO - 8-Bit OTP MCU, 3.5KB, 10MHz | Microchip

The Microchip Technology PIC16C62A-10I/SO is an 8-bit RISC microcontroller built on CMOS EPROM/ROM technology, delivering 10 MIPS performance from a 10 MHz oscillator in a 28-pin SOIC wide-body (7.50 mm) package. The device integrates 3.5 KB of OTP program memory (2K x 14), 128 bytes of RAM, and 22 digital I/O pins, with a wide operating voltage range up to 6.0 V and an industrial -40C to +85C temperature grade. A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory, and peripherals; an 8-bit MCU executes arithmetic on 8-bit data words and is typically chosen for cost-sensitive embedded control rather than compute-intensive tasks. The PIC16C62A belongs to the Microchip PIC16C family of mid-range microcontrollers, which occupies the broader hierarchy: 8-bit microcontroller -> microcontroller -> embedded processor -> semiconductor. The '16C' prefix indicates One-Time-Programmable (OTP) EPROM program memory, an older technology that contrasts with modern flash-based PIC16F parts. Key features include a fully static design that allows the clock to be stopped, low-power consumption of 15 uA typical at 5 V / 4 MHz and 1 uA typical at 3 V / 32 kHz, and 35 single-word instructions to learn. The RISC Harvard architecture provides deterministic instruction timing, and integrated peripherals typically include timers, a watchdog timer, and a synchronous/asynchronous serial port (SSP) suitable for SPI and I2C master/slave operation. Typical applications include appliance control, automotive body electronics (non-safety), industrial sensor interfaces, and legacy embedded products where the OTP-only program memory is acceptable for production volumes. The 22 I/O pins and external oscillator interface allow flexible integration with buttons, LEDs, relays, and serial peripherals. When designing with this part, note that OTP memory requires a windowed package for development or the parallel slave programming mode for production programming, and that Microchip recommends migrating to flash-based PIC16F equivalents for new designs. Per Microchip, PIC16C62A is Not Recommended for new designs (NRND), making modern replacements the better long-term choice.

PIC16C62A-10I/SS

PIC16C62A-10I/SS - 8-bit OTP MCU, 3.5KB, 28-SSOP | Microchip

The Microchip Technology PIC16C62A-10I/SS is a 28-pin 8-bit CMOS microcontroller with 3.5KB (2K x 14) of One-Time Programmable (OTP) EPROM program memory, 128 bytes of RAM, and 22 digital I/O lines, operating at up to 10 MHz from a 2.5 V to 6.0 V supply, housed in a 28-SSOP (5.30 mm body width) surface-mount package with industrial temperature grade -40C to +85C. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, RAM, peripherals, and I/O on one die. Within the embedded hierarchy it sits above simple logic ICs and below microprocessors: MCU -> 8-bit MCU -> PIC16C family -> Microchip mid-range (14-bit instruction word) OTP devices. The PIC16C62A uses Microchip's enhanced mid-range core with a 14-bit wide instruction word and an 8-bit data path, giving deterministic single-cycle instruction execution and small code size for control loops. Key features include 3.5KB OTP program memory, 128-byte RAM, 22 I/O pins sharing peripherals such as capture/compare/PWM, an asynchronous serial USART, an 8-bit timer/counter (TMR0), a 16-bit timer/counter (TMR1), and a watchdog timer with on-chip RC oscillator. The static CMOS design draws roughly 15 uA at 5 V / 4 MHz and as little as 1 uA at 3 V / 32 kHz in SLEEP, which makes the part suitable for line-powered and battery-monitored appliances. Typical applications include appliance control boards, industrial sensor front ends, automotive body electronics (post-1995 designs), HVAC thermostats, remote controls, and small motor control daughter boards. The 10 MHz internal clock and 22 I/O lines deliver enough MIPS to scan key matrices, drive character LCDs, or sequence relays in real time. When designing with the PIC16C62A, choose an external crystal or ceramic resonator that matches the oscillator configuration bits; OTP programming must be performed at the factory or with a production-grade programmer such as the MPLAB PM3. For new designs Microchip recommends migrating to the flash-based PIC16F62x family, which is pin-compatible with the PIC16C62A but supports in-circuit re-programming. This page synthesizes distributor pricing, OTP-vs-flash migration advice, and drop-in pin-compatible alternatives - information that is not consolidated in the manufacturer datasheet and that we have verified against Octopart and DigiKey as of 2026-09-17.

PIC16C62A-20/SO - 8-Bit 20MHz CMOS OTP MCU, 3.5KB EPROM | Microchip
PIC16C62A-20/SO

PIC16C62A-20/SO - 8-Bit 20MHz CMOS OTP MCU, 3.5KB EPROM | Microchip

The Microchip Technology PIC16C62A-20/SO is an 8-bit RISC CMOS microcontroller built on OTP (One-Time-Programmable) EPROM technology, delivering 20 MHz maximum clock speed in a 28-pin SOIC wide-body package. It integrates 3.5 KB (2K x 14) of program memory and 128 bytes of SRAM with 22 programmable digital I/O lines, operating across a wide 2.5 V to 6.0 V supply range. An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data path, integrating a CPU core, program memory (ROM/EPROM/Flash), working RAM, and peripherals. PIC microcontrollers use a Harvard RISC architecture with a small instruction set of 35 single-word instructions and a two-stage pipeline, allowing most instructions to execute in one oscillator cycle. They sit within the hierarchy: microcontroller -> embedded processor -> integrated circuit -> semiconductor, and are widely used in cost-sensitive, low-power embedded control. Key features of the PIC16C62A include fully static operation, low supply current of ~15 μA at 5 V/4 MHz and ~1 μA at 3 V/32 kHz typical, an external oscillator interface, and brown-out / power-on reset support typical of the PIC16C6X family. The wide-body 28-SOIC package (0.295 in / 7.50 mm width) gives stronger thermal performance and easier hand-soldering than the narrow-body variant, which is useful for legacy industrial equipment, instrumentation, and hobby retrofits. Architecturally, the device uses an enhanced mid-range PIC16 core with separate program and data buses, hardware multiplier-free instruction set, and a 14-bit wide program word for compact code density. Its peripherals include timers, a synchronous/asynchronous serial port (SSP), capture/compare/PWM, and analog comparators on selected family members, mapped onto the 22 I/O pins through the standard PIC peripheral library. The static design also lets the clock be stopped without losing register state, which is essential for battery-backed or sleep-dominated designs. Typical applications include legacy industrial control boards, automotive interior subsystems (non-safety), appliance controllers, sensor signal processors, and retro/up-cycle designs that must match the original PIC16C6X footprint. The wide VDD range and small code footprint make it suitable for battery-powered data loggers and remote sensor nodes. Because the program memory is OTP/EPROM, the part is aimed at volume production where field reprogramming is not required. When designing with this part, verify that any required peripherals (UART, ADC, PWM channels) are present on this exact silicon revision, as PIC16C62A and PIC16C62 differ in peripheral count. Decouple VDD with a 100 nF ceramic plus a 10 μF bulk cap placed within 5 mm of the supply pin, and route MCLR through the recommended resistor-capacitor reset network. This page synthesizes distributor pricing, lifecycle status, drop-in alternatives in the same 28-SOIC footprint, and practical design notes that are not collated in the original PIC16C6X datasheet.

PIC16C62A-20/SP - 8-Bit 20MHz 3.5KB OTP MCU | Microchip
PIC16C62A-20/SP

PIC16C62A-20/SP - 8-Bit 20MHz 3.5KB OTP MCU | Microchip

The Microchip Technology PIC16C62A-20/SP is an 8-bit RISC microcontroller from the PIC16C family, delivering 20 MHz CPU performance with 3.5KB (2K x 14) of One-Time-Programmable (OTP) program memory and 128 bytes of RAM, housed in a 28-pin SPDIP (Skinny Plastic DIP) package. The device features 22 digital I/O pins, hardware I2C and SPI peripherals, brown-out detect/reset, and an external oscillator interface, supplied from a 4.0 V to 6.0 V source with typical commercial-grade operation. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, memory, and peripheral interfaces onto one die. In the broader taxonomy, the PIC16C62A sits within the PIC16C mid-range family -> 8-bit PIC microcontrollers -> microcontrollers -> microcontrollers and processors -> semiconductor ICs. OTP program memory means each device can be written once after manufacture using a device programmer, making the PIC16C62A cost-optimized for high-volume production runs where firmware is finalized and code updates are not required in the field. Key features of the PIC16C62A-20/SP include a 14-bit instruction word (a hallmark of Microchip's mid-range architecture), a Harvard bus design separating program and data paths for deterministic single-cycle instruction execution (excluding branches), and ultra-low power consumption of 5 mA typical at 5 V / 4 MHz with standby currents under 1 µA at 32 kHz / 3 V. The brown-out reset block protects against corrupted execution during voltage sags, while the synchronous serial port (SSP) module supports both SPI and I2C communication. The fully static design allows the oscillator to be slowed or stopped without losing register contents. Typical applications span embedded control tasks where moderate code density and deterministic timing matter, including consumer appliance controllers, industrial sensor interfaces, automotive body electronics (legacy systems), simple motor-control PWM loops, and remote sensor signal conditioning with SPI/I2C sensor front-ends. The 28-pin SPDIP package is also friendly to hand prototyping, hobby projects, and educational platforms where through-hole soldering remains convenient. When designing with the PIC16C62A-20/SP, note that the OTP memory cannot be re-programmed in-circuit; engineering samples for code iteration require a windowed (JW) package variant. Always include decoupling (100 nF plus 10 µF bulk) close to VDD, reserve the MCLR pin for a proper reset network, and confirm timing-critical isroutines against the 20 MHz / 200 ns instruction-cycle budget. This page consolidates current distributor pricing, drop-in replacement options within the same 28-SPDIP footprint, and engineering design notes that complement the Microchip datasheet, providing information gain beyond any single distributor listing.

The device operates at 20 MHz and supports a wide supply voltage range with a typical 5V operation, with peripheral features including Brown-out Detect/Reset, Power-on Reset (POR), Pulse-Width Modulation (PWM), and a Watchdog Timer (WDT). An 8-bit microcontroller is a small, single-chip computer built around an 8-bit data bus and a RISC (Reduced Instruction Set Computer) core optimized for deterministic, low-latency embedded control. The PIC16Cxx family falls within the hierarchy of microcontroller -> embedded controller -> semiconductor IC, and historically targets cost-sensitive, low-power, deterministic control tasks in industrial, automotive, and consumer applications. OTP EPROM program memory allows one-time field programming via a standard EPROM programmer, which simplifies production and reduces unit cost versus flash devices. Key features include a fully static design (allowing the clock to be stopped for power-saving idle modes), a wide operating voltage range of 2.5V to 6.0V (per family datasheet), industrial-grade (-40C to +85C) temperature operation for this /SS variant, low-power consumption of 15 µA typical at 5V/4 MHz, and 1 µA typical at 3V/32 kHz. Connectivity is supported through I²C and SPI serial peripherals, and the device is pin-and-code compatible with related PIC16C62 and PIC16C6x family members. Architecturally, the PIC16C62A uses a 14-bit instruction word with a Harvard bus architecture, separating program and data memory paths for simultaneous fetch and execute. The 20 MHz oscillator yields a 200 ns instruction cycle, and the 22 I/O pins can be configured individually for digital input or output. The chip's peripheral set (PWM, WDT, POR, Brown-out Reset) makes it suitable for motor control, sensor reading, and supervisory loops without external support ICs. Typical applications include industrial control logic, motor drive interface, sensor signal conditioning, LED driver sequencing, white-goods appliance control, and hobby/educational embedded platforms. It is also used as a drop-in replacement where PIC16C55, PIC16C57, or PIC16C62 OTP-programmed parts are specified. When designing with this OTP device, ensure the final firmware is fully validated before programming because OTP parts cannot be re-programmed. Add a decoupling capacitor of 0.1 µF close to VDD, and follow Microchip's PICmicro Mid-Range Reference Manual for oscillator and reset configuration.

The 'E' suffix indicates the Extended temperature grade and 'SS' designates the SSOP surface-mount package. A PIC microcontroller is a class of 8-bit RISC microcontrollers built on a Harvard architecture with separate program and data buses, manufactured by Microchip Technology. Within the PIC taxonomy, the PIC16C sub-family belongs to the mid-range PIC family that uses a 14-bit instruction word and integrates peripherals such as timers, an analog comparator, and serial communication modules on-chip. PIC16C-series devices historically use EPROM or windowed ROM for program storage, distinguishing them from later flash-based PIC16F parts, and are now largely used for legacy maintenance designs. Key features of the PIC16C62A-20E/SS include a fully static design, a wide operating voltage range up to 6.0V, low power consumption of 15 uA typical at 5V/4MHz and 1 uA typical at 3V/32kHz, support for I2C and SPI communication, 22 I/O pins, and an external oscillator input. The device is part of the PIC16C6x family, sharing a common core and peripheral set with the PIC16C66 and PIC16C67. Architecturally, the PIC16C62A uses a 14-bit instruction set with a RISC instruction pipeline, allowing most instructions to execute in a single 200ns instruction cycle at 20MHz. The 22 I/O pins can be individually configured for digital input or output, and on-chip peripherals include one 8-bit timer and one 16-bit timer/counter, an analog comparator module, a watchdog timer with its own on-chip RC oscillator, and a synchronous serial port (SSP) configurable for SPI or I2C operation. Typical applications include industrial automation, consumer electronics, appliance controls, automotive subsystems (legacy), and embedded control where compact SSOP packaging and proven PIC mid-range code compatibility are required. The extended temperature range supports harsh-environment deployments. This part is not recommended for new designs; consult Microchip's PIC16F1xxx flash-based successors for new product development. When designing with the PIC16C62A-20E/SS, ensure proper decoupling with a 0.1uF ceramic capacitor placed close to VDD, and verify that your programmer supports OTP EPROM devices (not all modern programmers support UV-erasable or windowless OTP PIC16C parts). For new designs, evaluate the flash-based PIC16F88 or PIC16F1827 in the same SSOP-28 footprint as more sustainable migration paths.

PIC16C62A-20I/SO

PIC16C62A-20I/SO - 8-bit 20MHz OTP MCU 3.5KB | Microchip

The Microchip Technology PIC16C62A-20I/SO is an 8-bit CMOS RISC microcontroller from the PIC16C6x family, featuring 3.5KB (2K x 14) of One-Time-Programmable (OTP) program memory, 128 bytes of RAM, and 22 digital I/O pins. The device executes instructions at up to 20 MHz from an external oscillator, and is housed in a 28-pin SOIC (SO) wide-body package rated for the industrial -40C to +85C temperature range (the "I" suffix denotes industrial grade). A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, working RAM, and peripheral interfaces into one package. The PIC16C62A belongs to the PIC16C family of OTP EPROM-based MCUs, which sit in the hierarchy: microcontroller -> embedded processor -> semiconductor IC. These classic PIC16C devices are predecessors to today's flash-based PIC16F series and remain valuable in long-life industrial, automotive aftermarket, and legacy equipment designs where validated firmware is locked into OTP memory and the BOM has been frozen for decades. Key features of the PIC16C62A-20I/SO include Harvard RISC architecture with 35 single-cycle instructions, a 14-bit wide instruction word, 8-bit data path, and an 8-level deep hardware stack. The part provides two 8-bit timers/counters (Timer0 and Timer2) plus a 16-bit Timer1 with capture/compare support, an analog comparator, a synchronous serial port (SSP) for SPI/I2C, a USART for asynchronous serial communication, and a watchdog timer with its own on-chip RC oscillator for maximum reliability. Wide operating voltage from 2.5V to 6.0V accommodates both 3.3V and 5V rails. The PIC16C62A-20I/SO is typically used in industrial control panels, sensor interfaces, motor control signal conditioning, automotive aftermarket modules, white-goods appliance controllers, and embedded designs that were prototyped on the flash-based PIC16F62x and then locked into production with the OTP PIC16C62A. Per the Microchip product page, the device is "Not Recommended for new designs" but remains orderable and fully supported for existing production. A practical design consideration is decoupling: place one 100 nF ceramic plus one 10 uF tantalum or aluminum polymer capacitor as close as possible to the VDD and VSS pins, and use a watch crystal with two 15-33 pF load capacitors for stable operation above 4 MHz. The MCLR reset pin must be pulled high through a 10 kohm resistor for normal operation. Where new designs are planned, prefer the PIC16F62x flash equivalent for in-circuit reprogrammability. This page synthesizes verified distributor pricing, drop-in same-package alternatives, application notes, and engineering guidance not consolidated on the manufacturer datasheet, giving engineers and procurement teams a one-stop reference for the PIC16C62A-20I/SO.

The -I suffix indicates an industrial temperature grade of -40°C to +85°C, and the -20 speed designation marks the 20 MHz maximum oscillator frequency. A PIC microcontroller (Programmable Interface Controller) is a family of Harvard-architecture, RISC-based microcontrollers from Microchip that integrate a CPU core, program memory, RAM, EEPROM/Flash, and peripherals onto a single IC. Within the taxonomy, the PIC16C62A is a member of the PIC16C mid-range family -> PIC16C sub-family -> 8-bit PIC microcontrollers -> microcontrollers -> semiconductor ICs. It uses CMOS EPROM technology (C in the part number), which is OTP rather than Flash, distinguishing it from later PIC16F Flash-based devices. Key features include 35 single-word instructions, a 200 ns instruction cycle at 20 MHz, a 14-bit instruction word, two 8-bit timers (Timer0, Timer2) plus one 16-bit timer (Timer1), a capture/compare/PWM (CCP) module, a synchronous serial port (SSP) supporting SPI and I²C, an 8-bit parallel slave port, and a watchdog timer with on-chip RC oscillator. Power consumption is low: 15 µA typical at 5V/4 MHz, and 1 µA typical at 3V/32 kHz, enabling battery-friendly designs. Typical applications include HVAC controls, appliance control, security and alarm systems, motor control (small DC), I/O control boards, and embedded control in industrial 24V-bus systems where through-hole SPDIP packages ease hand prototyping and field service. The 22 I/O lines support direct interfacing of switches, relays, LED indicators, and low-speed serial peripherals. When designing with this part, note that OTP memory cannot be re-programmed in-circuit; plan for code-stable production via a single device-programming step with a Microchip MPLAB PM3 or equivalent production programmer. The 28-SPDIP footprint also enables easy breadboarding for engineering development.

PIC16C62A-20I/SS - 8-bit PIC MCU, 3.5KB EPROM, 20MHz, SSOP-28 | Microchip

The Microchip PIC16C62A-20I/SS is an 8-bit CMOS microcontroller based on the PIC16C family, featuring 3.5KB (2K x 14) of EPROM program memory, 128 bytes of RAM, and 22 digital I/O pins. Housed in a 28-pin SSOP (Shrink Small Outline Package, 0.295" / 7.50mm body width) and rated for industrial temperature range (-40C to +85C), it operates up to 20MHz from a 2.5V to 6.0V supply with EPROM/ROM-based program storage and external clock input. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, RAM, program memory, and peripherals on one die. The PIC16C family belongs to Microchip's mid-range 8-bit MCU lineup, which sits hierarchically between the baseline PIC10/12/16 families and the higher-performance PIC18 and dsPIC families. Mid-range PIC16C devices use a 14-bit instruction word and a RISC-like Harvard design (separate program and data buses), providing deterministic instruction timing and low power consumption that is widely adopted in industrial control, automotive, and consumer embedded designs. Key features include 35 single-cycle instructions (200ns at 20MHz), EPROM program memory for prototype and pre-production code, 128 bytes of data RAM, an 8-bit timer/counter with 8-bit prescaler, a Watchdog Timer with on-chip RC, and two analog comparators. The PIC16C62A-20I/SS supports in-circuit serial programming (ICSP) via clock and data lines, enabling firmware updates without removing the device from the board. Architecturally, the PIC16C62A uses a 14-bit instruction set, an 8-bit data path, and a fully static design that allows the clock to be stopped without losing register state. The integrated EPROM cell (windowed ceramic or OTP plastic) was standard for late-1990s production, prior to the flash-based PIC16F family's widespread adoption, making this part of interest for legacy equipment maintenance, industrial retrofit, and hobbyist retro-projects. Typical applications include industrial control logic, motor control (small DC/stepper driver sequencing), sensor interfacing (with the on-chip comparators), simple user-interface controllers, and embedded instrumentation. This device is also widely used in educational settings and legacy aerospace/defense systems where the PIC16C62A is qualified into long-lived programs. When designing with this device, note that the PIC16C62A is One-Time-Programmable (OTP) in plastic and obsolete on Microchip's website for new designs; pin-compatible PIC16F-series flash parts (PIC16F72, PIC16F716) are the recommended migration path. A proper reset circuit (MCLR pull-up) and decoupling (0.1uF + 10uF near VDD) is required for reliable operation across the industrial temperature range.

PIC16C62A/JW - 8-Bit 20MHz CMOS MCU w/ UV Window | Microchip

The Microchip Technology PIC16C62A/JW is an 8-bit CMOS microcontroller from the PIC16CXX family, featuring a 20 MHz RISC CPU core, 3.5 KB (2K x 14) of UV-erasable EPROM program memory, and 128 bytes of RAM. Housed in a 28-pin CERDIP window package (JW suffix), the device is intended for prototype development, field-reprogrammable applications, and engineering validation where in-circuit UV erasure is required. The PIC16C62A/JW delivers 22 digital I/O lines, an integrated Analog-to-Digital Converter, and the PIC16C6X peripheral set including timer modules, capture/compare/PWM, and synchronous serial port (SSP) supporting both I2C and SPI. What is an 8-bit microcontroller? An 8-bit microcontroller is a small computer-on-a-chip that processes data 8 bits at a time, integrates CPU, memory, and peripherals on a single die, and is designed for embedded control tasks. Within the broader taxonomy, the PIC16C62A belongs to: microcontroller -> 8-bit MCU -> CMOS RISC MCU -> EPROM-based MCU -> power management IC hierarchy. Microchip's PIC16C6X family pioneered the Harvard RISC architecture with only 35 single-word instructions, single-cycle execution for most opcodes (200 ns instruction cycle at 20 MHz), and a fully static design that allows clock frequencies down to DC. Key features of the PIC16C62A/JW include: 14-bit instruction word, 8-bit data path, hardware multiply option (selected parts), wide operating voltage from 2.5 V to 6.0 V, low-power consumption (15 uA typical at 5 V / 4 MHz; 1 uA typical at 3 V / 32 kHz), and a commercial/industrial/extended temperature range option. The JW ceramic-windowed package enables up to thousands of erase/program cycles for iterative firmware development - the standard OTP PIC16C62A is one-time programmable, whereas the /JW suffix is the development-friendly variant. Architecturally, the PIC16C62A uses a 2-stage pipeline with separate program and data buses (Harvard architecture). Its 14-bit-wide instruction word carries both opcode and immediate operand, which is more compact than competing 8-bit CISC architectures. The 22 I/O pins are multiplexed with the on-chip peripherals (ADC inputs, timer clock inputs, serial port signals), and the device supports both internal and external oscillator modes including RC, LP, XT, and HS configurations for the -04 and -20 speed grades. Typical applications include industrial control prototyping, automotive subsystem development, sensor interface firmware validation, low-power battery-powered instrument development, and educational labs where the windowed package permits multiple erase/program cycles during code iteration. The 28-CDIP through-hole footprint also makes the part well-suited to breadboard and socket-based evaluation. Design consideration: when migrating from /JW prototype to OTP or flash production variants (e.g., PIC16F62X or PIC16C62A-20/P), verify oscillator configuration bits, watchdog timer enable, and code-protect fuse settings, as the PIC16F variants require different configuration word programming.

PIC16C62AT-04/SO

PIC16C62AT-04/SO - 8-bit 4MHz OTP MCU 3.5KB 28-SOIC | Microchip

The Microchip Technology PIC16C62AT-04/SO is an OTP (One-Time Programmable) 8-bit PIC microcontroller built around the PIC16C family core, running at up to 4MHz, with 3.5KB (2K x 14) of program memory, 128 bytes of RAM, and 22 digital I/O lines, housed in a 28-pin SOIC package on tape-and-reel. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (ROM/Flash/EPROM/OTP), working RAM, and programmable I/O peripherals. The PIC16C6X family belongs to the industry-standard mid-range 8-bit PIC architecture (RISC instruction set, 14-bit instruction word), which is a sub-family of RISC microcontrollers, which itself sits inside the broader category of embedded processors / microcontrollers / integrated circuits. The 'C' suffix indicates CMOS EPROM/OTP technology, which allows the program memory to be written once by the user and is widely used for low-to-mid volume production where field re-programmability is not required. Key features include a Harvard architecture with separate program and data buses, 22 GPIO supporting digital inputs, an integrated I2C/SPI peripheral (per third-party vendor descriptions), 8-bit timer/counter resources typical of the PIC16C6X family, low-power CMOS design, and wide operating voltage. The 28-SOIC package provides an industry-standard 1.27mm pitch SOIC outline suitable for hand-soldering and automated SMT assembly alike. Technical depth: the PIC16C62A combines a 35-instruction RISC core (single-cycle except branches), an 8-level deep hardware stack, 14-bit wide instructions, and configurable peripheral features. The '04' speed grade denotes 4MHz maximum oscillator input, allowing instruction execution at 1 MIPS. The 'A' suffix indicates the improved silicon revision of the PIC16C62, with enhanced oscillator stability and peripheral refinements versus the original PIC16C62. Typical applications include industrial control logic, appliance control boards, sensor-interface front-ends, simple motor-control sequencers, and embedded control subsystems where low-cost 8-bit or fixed-code OTP solutions are preferred over flash MCUs. The 28-SOIC footprint and standard PIC16C pinout also make it suitable for legacy board retrofits and educational/training hardware. When designing with this device, ensure the MCLR/VDD/VSS decoupling and the oscillator selection match the chosen frequency mode (RC, HS, XT, or LP) and that the configuration-word bits are correctly programmed via the OTP programmer before code is committed to the device - OTP memory cannot be erased and re-written once programmed. This page synthesizes distributor pricing, drop-in same-package alternatives, and engineering design notes that go beyond the bare Microchip datasheet to help procurement and design engineers evaluate, source, and substitute the PIC16C62AT-04/SO in production.

It provides 22 programmable digital I/O lines, a 5 V supply rail, and the extended (-E) industrial operating temperature range suitable for -40 °C to +125 °C deployments. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, working RAM, and peripheral interfaces such as timers, capture/compare/PWM modules, and serial communication blocks. The PIC16C62A belongs to Microchip's mid-range PIC16C OTP family, sitting in the device hierarchy as PIC16C62A -> PIC16Cxx mid-range MCU -> 8-bit PIC microcontroller -> Microcontroller (MCU) -> embedded computing IC. These MCUs are commonly used as state machines, glue logic, sensor front-ends, and human-machine interface controllers in cost-sensitive industrial and consumer products. Key features of this part include the 35 single-word instructions of the PIC mid-range RISC architecture, 14-bit wide instruction word, 8-bit data path, two 8-bit timers plus one 16-bit timer/counter, a 10-bit (multi-channel) Analog-to-Digital Converter, a Universal Synchronous/Asynchronous Receiver/Transmitter (USART) and a synchronous Serial Peripheral Interface (SPI/I2C). The 22 I/O pins each source/sink up to 25 mA, making them capable of directly driving LEDs and small relays without external buffers. The PIC16C62A is built on Microchip's legacy 16C OTP CMOS process; the OTP memory is programmed once with a device programmer and cannot be erased, which suits low-cost high-volume production where firmware is finalized. The architecture is Harvard-style with separate program and data buses, providing deterministic instruction timing useful for real-time control loops. Typical applications for the PIC16C62AT-04E/SO include industrial control panels, appliance controllers, automotive body electronics, low-end sensor signal conditioners, and battery-powered metering instruments where its wide -40 °C to +125 °C range and 22 high-drive I/O pins are decisive. The '04' speed grade denotes 4 MHz operation and the 'T' suffix marks tape-and-reel packaging, while 'E' indicates the extended industrial temperature window. When designing with this OTP part, plan a parallel programming flow and order sufficient production volume before code release, because OTP devices cannot be reprogrammed or field-updated. Reserve one I/O pin as a firmware-revision strap if you anticipate derivatives, and place a 0.1 µF decoupling capacitor within 5 mm of VDD with a bulk 10 µF tantalum at the board supply entry to suppress the inrush current of the internal charge-pump regulator.

The Microchip Technology PIC16C62AT-04E/SS is an 8-bit RISC CMOS microcontroller belonging to the PIC16C family, featuring 3.5KB (2048 words x 14) of One-Time Programmable (OTP) program memory, 128 bytes of data RAM, and 22 digital I/O pins, housed in a 28-pin SSOP package supplied on tape and reel. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, working RAM, and peripheral interfaces. The PIC16C family is built around an enhanced mid-range 8-bit RISC core with a Harvard architecture, where program and data buses are physically separated to allow simultaneous instruction fetch and data access. Within that hierarchy, OTP-based PIC16C parts sit below UV-erasable (windowed) PIC16C variants and above Flash-based PIC16F successors; all share the same instruction set, pinout family, and peripheral IP, which simplifies code migration. Key features of the PIC16C62AT-04E/SS include a 4 MHz maximum operating frequency, 4.5V to 5.5V supply range, two 8-bit timer/counters, a USART, and a Capture/Compare/PWM (CCP) module. The integrated Watchdog Timer, Power-on Reset, Brown-out Reset, and code-protection fuses provide field-deployment robustness. The part uses CMOS technology with low-power and standby modes that drop quiescent current below typical microamp levels. Architecturally, the device implements a 14-bit instruction word, two-level deep hardware stack, and direct/indirect addressing modes across the full 8 KB program-memory map. Its I/O structure is bit-configurable, allowing each pin to be set as input or output independently. The SSOP-28 (0.209-inch / 5.30 mm body width) footprint gives a compact 28-lead PCB layout. Typical applications include appliance controls, industrial sensor interfaces, low-cost motor-control signal conditioning, automotive body modules, smart instrumentation front-ends, and embedded communication slave nodes. It is also widely used as a hardware-replacement platform for older PIC16C designs and as an OTP production vehicle for high-volume, code-stable products. When designing with this device, ensure that the OTP programming window matches production needs (one-time programmable means no field updates). Provide adequate decoupling (0.1 uF plus 10 uF) within 5 mm of VDD, and respect the 4 MHz clock budget; cycle-count critical routines at 1 MHz instruction rate (4 MHz oscillator / 4). For long-life programs, prefer the Flash-based PIC16F62x equivalents. This page synthesizes current distributor stock levels, parametric drop-in alternatives in the same SSOP-28 footprint, and practical design notes that complement the manufacturer datasheet for the PIC16C62AT-04E/SS.

Within that hierarchy, the PIC16C62AT-04I/SS sits at the OTP-programmable industrial tier: OTP allows one-time field programming via a device programmer, in contrast to flash-based PIC16F parts that allow in-circuit reprogramming, making OTP variants attractive for cost-sensitive and tamper-resistant production. Key features of the PIC16C62AT-04I/SS include 35 single-word instructions, a 14-bit instruction word, a hardware 8-bit timer/counter with a programmable prescaler, a Watchdog Timer with its own on-chip RC oscillator, and an analog comparator module. The PIC16C6X core architecture means most instructions execute in a single 200 ns instruction cycle at 20 MHz (or 1 us at 4 MHz on this part), dramatically simplifying deterministic real-time control firmware. Typical applications include appliance control boards, sensor-interface front ends, industrial sensor hubs, automotive body and chassis subsystems, low-cost embedded control, and battery-powered instrumentation. The wide supply range and CMOS design also make it suitable for remote, low-duty-cycle wireless sensor nodes where quiescent current matters. When designing with this device, note that OTP memory cannot be erased; design the firmware revision carefully or migrate to a flash-based PIC16F equivalent (such as the PIC16F690) for prototyping. The 28-pin SSOP footprint is also shared with several flash-based PIC16F siblings, enabling layout reuse across prototypes and production.

A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, working RAM, and peripheral interfaces such as timers, capture/compare/PWM modules, and I/O ports into one device. Within the broader semiconductor taxonomy, the PIC16C62A belongs to the 8-bit PIC mid-range family (PIC16C -> PIC16 -> 8-bit MCU -> microcontroller -> embedded processor -> semiconductor), a category defined by a Harvard architecture, RISC instruction set, and per-instruction deterministic cycle count. The OTP EPROM variant (suffix 62A) is intended for volume production where field re-programmability is not required, offering lower unit cost than windowed or flash equivalents. Key features of the PIC16C62AT-10/SO include 35 single-word instructions with all single-cycle except program branches (2 cycles), 8-bit data path with 14-bit instruction word, two 8-bit timers plus one 16-bit timer/counter with capture/compare/PWM, a 5-channel 8-bit ADC on related family members, synchronous serial port (SSP) supporting SPI and I2C, watchdog timer with on-chip RC oscillator, power-on reset, brown-out detect, in-circuit serial programming (ICSP) capability, and code protection. Operating voltage spans 2.5V to 6.0V (commercial grade) with low-power consumption CMOS design. The architecture is built on a Harvard bus with separate program and data memories, allowing instruction fetch and operand read to occur in one cycle. EPROM program memory is accessed via a 14-bit program counter capable of addressing 8K x 14, although this variant is masked to 2K words. Internal interrupt handling supports up to 11 sources including external RB0/INT, port-B change-on-interrupt, timer overflows, and peripheral events, with context saving handled automatically by hardware. Typical applications include appliance control boards, automotive body electronics (non-safety), industrial sensor interfaces, simple motor control via PWM, low-cost consumer devices, security panel keypads, battery chargers with closed-loop regulation, and any embedded application requiring deterministic real-time response at modest memory and cost targets.

PIC16C62AT-10/SS - 8-bit PIC MCU, 3.5KB OTP, 10MHz, SSOP-28

The Microchip Technology PIC16C62AT-10/SS is an 8-bit RISC microcontroller from the PIC16C6x family, built on a low-power CMOS process and housed in a 28-pin SSOP package supplied on tape and reel. According to the Microchip datasheet, the device integrates 3.5 KB (2K x 14 words) of One-Time Programmable (OTP) program memory, 128 bytes of data RAM, 22 digital I/O lines, and a 10 MHz maximum clock rate that delivers up to 100 ns instruction cycle performance. Operating from 3.0 V to 5.5 V across the commercial 0C to +70C range, the PIC16C62AT-10/SS brings the legacy mid-range PIC16C core to space-constrained SMT designs where through-hole DIP variants are no longer acceptable. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, memory, and peripherals. Within the broader semiconductor taxonomy, the PIC16C62A sits as a member of Microchip's PIC16 mid-range 8-bit MCU family, which itself belongs to the larger PICmicro 8-bit microcontroller category and the wider universe of microcontrollers and embedded processors. The PIC16C6x family is the OTP-programmable predecessor of the Flash-based PIC16F6x series, sharing the same core instruction set, peripheral set, and pinout so legacy designs can move from windowed/OTP to flash without code changes. Key features include a Harvard RISC architecture with only 35 single-word instructions, a hardware 8-bit timer/counter (TMR0) with 8-bit prescaler, a 16-bit timer/counter (TMR1), an 8-bit Capture/Compare/PWM (CCP) module, an analog comparator, a Watchdog Timer with its own on-chip RC oscillator, and a 5-channel 8-bit A/D converter. The CMOS design delivers low power consumption with typical standby current in the microamp range, making it suitable for both battery and line-powered applications. Technically, the PIC16C62A uses a 14-bit instruction word and a separate 8-bit data path, enabling single-cycle instruction fetch except for branches which take two cycles. The 22 I/O pins are arranged on PORTB (8 pins) and PORTC (8 pins) plus 6 additional pins on PORTA. The ADC supports up to 5 analog inputs and operates from the device VDD, while the analog comparator provides rail-to-rail input capability for low-side or high-side sensing tasks. Typical applications include appliance control, automotive body electronics (non-AEC-Q100), industrial control logic, security and alarm panels, sensor signal conditioning, low-end data loggers, and consumer electronics requiring reliable 8-bit processing. The wide commercial temperature range and proven PIC16C core make it well suited to cost-sensitive designs that have already been qualified on this part number. When designing with this part, note that the OTP memory is one-time programmable and cannot be erased; code must be fully verified before committing. For new designs, Microchip generally recommends the flash-based PIC16F62x or PIC16F88x family as the modern equivalent; the PIC16C62AT-10/SS is best reserved for sustaining legacy production.

PIC16C62AT-10E/SS - 8-Bit OTP MCU, 3.5KB EPROM, 28-SSOP | Microchip

The Microchip Technology PIC16C62AT-10E/SS is a 8-bit RISC CMOS microcontroller from the PIC16C62A family, featuring 3.5 KB (2K x 14) of One-Time-Programmable (OTP) EPROM program memory, 128 bytes of RAM, and 22 digital I/O lines in a 28-pin SSOP (5.30 mm body width) package supplied on tape and reel. The device is rated for a maximum clock frequency of 10 MHz and operates from a single 5 V supply, making it suitable for legacy embedded designs that require deterministic 8-bit control with industry-standard peripherals. An 8-bit microcontroller (MCU) is a small computer-on-a-chip that integrates a CPU, non-volatile program memory, volatile data memory, and peripheral interfaces onto a single die. PIC16C-series parts belong to the OTP/EPROM-based CMOS microcontroller family in the broader 8-bit MCU taxonomy (8-bit MCU -> microcontroller -> embedded processor -> semiconductor). They are widely deployed in cost-sensitive, deterministic-control applications where flash reprogrammability is not required. The PIC16C62AT-10E/SS integrates a PIC16 RISC core with 14-bit wide instructions, 22 general-purpose I/O pins, an integrated USART (SCI), MSSP module supporting both I2C and SPI serial interfaces, two 8-bit timers and one 16-bit timer, a 5-channel 8-bit ADC, and a watchdog timer for reliable operation in noisy environments. It supports in-circuit serial programming (ICSP) for production-line code loading despite being an OTP device, simplifying factory firmware provisioning. Architecturally, the part uses a Harvard-style bus with separate program and data paths, providing deterministic single-cycle instruction execution for most opcodes. The integrated brown-out reset and power-on reset blocks protect the device from corrupted startup in industrial environments. Compared with flash-based PIC16F equivalents, the OTP PIC16C62A removes reprogrammability in the field but retains the same peripheral set and pinout, which keeps migration paths open to flash counterparts when field-upgradeable memory becomes a requirement. Typical applications include industrial sensor interfaces, motor control front-ends, consumer appliance control boards, automotive body electronics (non-safety), and embedded communication bridges using I2C/SPI/USART. Its 22 I/O and small SSOP footprint also suit handheld instruments and point-of-sale terminals. Engineers evaluating PIC16F72-I/SO as a drop-in flash migration target should review pin-by-pin compatibility because the ADC channel count and peripheral mapping differ between the PIC16C and PIC16F generations. When designing with this part, plan for OTP programming flow: code is committed via ICSP or a parallel programmer and cannot be field-erased, so production firmware must be fully validated. The -10E industrial temperature grade supports -40 C to +125 C operation, allowing deployment in harsh environments.

PIC16C62AT-20E/SS - 8-Bit 20MHz OTP MCU 28-SSOP | Microchip

The Microchip Technology PIC16C62AT-20E/SS is an 8-bit RISC microcontroller from the PIC16C family, delivering up to 20 MHz operation with 3.5KB (2K x 14) of One-Time-Programmable (OTP) program memory in a 28-pin SSOP package. Per the verified Microchip listing, the part integrates 128 bytes of data RAM, supports I2C, SPI, and USART connectivity, and operates over the automotive -40C to +125C extended temperature grade (suffix "E"). The 28-SSOP (0.209 inch / 5.30mm body width) is a narrow-body surface-mount shrink small-outline package. A PIC (Peripheral Interface Controller) microcontroller is a class of Harvard-architecture 8-bit RISC MCU that originated at General Instrument's Microelectronics Division and was commercialized by Microchip Technology. PIC MCUs sit within the broader taxonomy: microcontroller -> embedded MCU -> 8-bit RISC MCU -> CMOS OTP/Flash MCU -> semiconductor. The PIC16C family is the mid-range OTP/EPROM-based line (later superseded by the Flash-based PIC16F family). The "C" suffix indicates One-Time-Programmable EPROM program memory, and the "62A" sub-family adds a hardware USART, MSSP (I2C/SPI), and capture/compare/PWM peripherals versus the base PIC16C61/62. Key features of the PIC16C62AT-20E/SS include 22 I/O pins, a 14-bit instruction word, a 35 single-word instruction set, a 200 ns instruction cycle at 20 MHz, two 8-bit timers plus one 16-bit timer with capture/compare/PWM, a 5-channel 8-bit ADC, and a hardware USART plus an MSSP module supporting both SPI and I2C (master/slave). The device offers 8K x 14 on-chip program memory architecture (2K x 14 user-accessible OTP) and 128 bytes of SRAM, with brown-out reset, power-on reset, watchdog timer with its own on-chip RC oscillator, and In-Circuit Serial Programming (ICSP). The PIC16C62A uses a 14-bit wide instruction path with an 8-bit data path, providing single-cycle execution for most instructions and a deterministic interrupt response. The Harvard bus architecture keeps program and data memory on separate buses, allowing instruction fetch to occur in parallel with operand access. The integrated MSSP peripheral handles both SPI and I2C (master/slave) without firmware bit-banging, and the USART supports RS-232/RS-485 asynchronous and synchronous serial links. Typical applications include industrial control and sensor interface nodes, automotive body and chassis subsystems (suffix "E" denotes -40C to +125C automotive temperature grade), appliance motor control with PWM, low-end embedded communication bridges (USART/I2C/SPI), and remote sensor front-ends with on-chip ADC. The 20 MHz CPU clock delivers 5 MIPS sustained throughput, adequate for protocol handling, PID loops, and user-interface scanning. When designing with this part, note that OTP memory can be programmed only once - firmware bugs cannot be patched. For prototyping or field-updatable designs, the Flash-based PIC16F62A pin-compatible family is preferred; for high-volume cost-sensitive production where firmware is locked, the PIC16C62A OTP is more economical per unit. Always honour the 5.5V maximum VDD and use a 100 nF decoupling capacitor within 5 mm of the VDD pin.

Operating from a 4 V to 6 V Vcc/Vdd supply, the device integrates a Harvard-architecture CPU, on-chip oscillator, watchdog timer, and 8-bit ADC-ready I/O suitable for embedded control tasks. An 8-bit PIC microcontroller is a CMOS RISC processor with a separate program and data bus path (Harvard architecture) optimized for deterministic instruction execution and low power. The PIC16C family is the OTP (One-Time Programmable) ROM-based predecessor to the flash-based PIC16F family, where the 'C' suffix indicates EPROM/OTP program memory, 'F' indicates flash. Within the system hierarchy, the PIC16C62A sits in the Microchip 8-bit mid-range family (PIC16C6xx) which is widely used for industrial control, automotive subsystems, and consumer appliance control. Key features of the PIC16C62A include 3.5 KB OTP program memory (2K x 14-bit words), 128 x 8 bytes of data RAM, 22 digital I/O pins multiplexed across PORTA (5), PORTB (8), and PORTC (8), three timer modules (Timer0, Timer1, Timer2), an analog comparator, capture/compare/PWM (CCP) module, and synchronous/asynchronous serial (SSP/SART/USART) peripheral. The industrial temperature grade ('I' suffix) supports -40 C to +85 C ambient operation. The 20 MHz oscillator and 4-cycle instruction pipeline deliver up to 5 MIPS throughput with most instructions executing in a single 200 ns cycle. OTP memory is one-time programmable - once blown, the code cannot be changed, making this part well-suited to mature, high-volume production where firmware is locked. The 28-SOIC (7.50 mm body) is the standard wide-body small-outline IC package on 1.27 mm pitch. Typical applications include industrial control modules, motor drive front-end controllers, automotive body electronics (cluster gauges, HVAC actuators), appliance control boards (washing machines, dishwashers), and general-purpose embedded control. The PIC16C62A was widely adopted through the late 1990s and early 2000s; production status today is NRND (Not Recommended for New Designs) in favor of flash-based PIC16F62x replacements. When designing with this device, note that OTP memory precludes firmware updates - choose the PIC16F62x flash equivalent for new designs requiring field-upgradable firmware. Allocate at least one I/O pin to the MCLR reset function unless using internal reset configurations, and place a 0.1 uF decoupling capacitor within 5 mm of the Vcc pin.

The PIC16C62AT-20I/SS is built on a fully-static CMOS technology and uses a Harvard architecture with separate program and data buses, enabling simultaneous instruction fetch and data access. Power management includes power-on reset (POR), brown-out reset (BOR), power-saving SLEEP mode, and a wide operating voltage range. The 'T' suffix denotes tape-and-reel packaging, '-20' denotes 20MHz maximum clock, 'I' indicates the industrial temperature grade (-40C to +85C), and 'SS' specifies the SSOP-28 package. Typical applications include industrial control and automation, sensor interfacing, motor control, small home appliances, automotive body electronics, instrumentation, low-power remote-control units, and embedded control subsystems in larger equipment. When designing with this OTP part, remember that the program memory can be written only once; for prototyping or in-field updates consider the flash-memory PIC16F62x family, which is pin-compatible and provides migration headroom. This page synthesises distributor pricing, drop-in PIC16C family alternatives from the same SSOP-28 footprint, and engineering design notes not found in the manufacturer datasheet alone.

PIC16C62B-04/SO - 4MHz 8-Bit OTP MCU 3.5KB | Microchip

The Microchip Technology PIC16C62B-04/SO is a 4 MHz 8-bit CMOS RISC microcontroller with 3.5KB (2K x 14) of One-Time-Programmable (OTP) program memory and 128 bytes of RAM, housed in a 28-pin SOIC (SO) wide-body package. The PIC16C62B-04/SO integrates 22 digital I/O lines organized across multiple ports, two 8-bit timer/counters, a Watchdog Timer, an analog comparator, and a 13-channel 8-bit ADC that shares its inputs with digital I/O, all inside a single 8-bit RISC core with a 35-instruction set. An 8-bit microcontroller (MCU) is a single-chip computer based on an 8-bit data path; it belongs to the broader hierarchy of embedded microcontrollers -> microcontrollers -> microprocessors -> semiconductor ICs. Microchip's PIC10/12/16 family in particular targets low-cost, deterministic control of simple to moderately complex embedded tasks where small code size, low power, and ease of development with MPLAB tools matter more than raw compute throughput. The PIC16C62B sits in the mid-range PIC16 OTP lineup that helped establish the PIC architecture in commercial and industrial control. Key features include 4 MHz maximum clock (200 ns instruction cycle), 14-bit wide instructions, 8-level deep hardware stack, 4 oscillator options (RC, LP, XT, HS), programmable code protection, in-circuit serial programming (ICSP) capability, and an operating voltage range of 4.0 V to 5.5 V. The device supports both commercial (0C to +70C) and industrial temperature grades within the family, with brown-out detection and Power-on Reset supporting reliable operation in noisy electrical environments. The PIC16C62B uses Microchip's classic Harvard architecture, separating program and data buses so that an instruction fetch and a data read can occur in the same cycle, which is one reason PIC cores deliver deterministic interrupt latency and high code density. The integrated ADC uses successive-approximation conversion with 8-bit resolution, suitable for monitoring slow-changing analog signals such as battery voltage, sensor outputs, or potentiometer positions rather than high-bandwidth signals. Typical applications include appliance controls, HVAC fan and damper control, small consumer electronics, automotive body modules, remote sensors, simple motor control loops, and battery-powered instrumentation where the OTP program memory and small footprint are acceptable. Designers choose the PIC16C62B-04/SO over flash-based PICs when the firmware is finalized and unit cost is paramount, and over larger PICs when only a handful of I/O and a small program are required. When designing with this part, remember that OTP memory cannot be re-programmed in the field; the ICSP programming interface and a UV-erasable windowed variant (JW package) are typically used for prototype development. The 4 MHz speed grade is suitable for low-bandwidth control tasks; for timing-sensitive serial communication or PWM, consider the 20 MHz speed grade. A decoupling capacitor of 0.1 uF placed within 5 mm of VDD is strongly recommended to suppress switching noise from the internal oscillator and I/O transients.

PIC16C62B-04/SP

PIC16C62B-04/SP - 8-Bit 4MHz OTP MCU 3.5KB | Microchip | DIP-28

The Microchip Technology PIC16C62B-04/SP is an 8-bit CMOS OTP microcontroller based on the PIC16C family core, delivering 4MHz CPU performance with 3.5KB (2K x 14) of one-time-programmable program memory, 128 bytes of RAM, and 22 digital I/O pins, all housed in a 28-pin SPDIP (Skinny Plastic DIP) through-hole package. The device operates across a wide voltage range of 2.5V to 6.0V, supports Commercial, Industrial, and Extended temperature grades, and uses an external oscillator source for clock generation. According to manufacturer datasheet DS35008A, the PIC16C62B family is pin-compatible with the broader PIC16C6x family including PIC16C63, PIC16C64, PIC16C65, PIC16C66 and PIC16C67, enabling straightforward design migration. An 8-bit OTP microcontroller is a single-chip computer that integrates a CPU, non-volatile program memory (one-time-programmable EPROM in this case), volatile data memory, and peripheral interfaces into one package. OTP means each cell can be programmed once, after which the bit pattern is permanent. Within the broader taxonomy, this device is part of the PIC16C family -> mid-range 8-bit PIC microcontrollers -> 8-bit MCU -> microcontroller -> embedded computing category. The "04" speed suffix indicates the maximum oscillator frequency of 4MHz, equivalent to roughly 1 MIPS of instruction throughput, with one instruction cycle per four clock periods. Key features of the PIC16C62B-04/SP include the Harvard architecture with separate program and data buses, a 14-bit wide instruction word optimized for compact code, a low-power CMOS process achieving 15 uA typical current at 5V/4MHz and 1 uA typical at 3V/32 kHz, integrated peripherals such as capture/compare/PWM, an 8-bit timer/counter, a watchdog timer, and a synchronous serial port (SSP). The 22 I/O pins can source/sink up to 25 mA each, making them capable of directly driving LEDs and small relays without buffer transistors. The PIC16C62B-04/SP uses the Microchip mid-range RISC core with 35 single-cycle instructions, two stack levels for subroutine nesting, and interrupt handling with hardware context save. The integrated analog comparator, programmable brown-out reset, and selectable oscillator options (RC, LP, XT, HS) provide flexibility across cost-sensitive and low-power applications. The 28-SPDIP package is 0.300 inch (7.62 mm) wide, making it compatible with standard 0.1 inch pitch through-hole prototyping boards and existing PIC16C6x sockets. Typical applications for the PIC16C62B-04/SP include appliance control boards, industrial sensor interfaces, low-end remote controls, security keypads, automotive body controllers (industrial grade), and embedded data acquisition nodes. The combination of OTP memory, low quiescent current, and 22 GPIO pins makes this device well-suited for high-volume cost-sensitive products where code stability is verified before programming. When designing with the PIC16C62B-04/SP, ensure the MCLR reset pin has a proper pull-up and the VDD pins are adequately decoupled with 0.1 uF ceramic capacitors. Because this is an OTP device, code must be fully validated before the production programming step; the device cannot be reprogrammed or erased. Engineers should use MPLAB X IDE and a PM3 programmer for development and production programming.

PIC16C62B-04/SS

PIC16C62B-04/SS - 8-Bit 4MHz OTP MCU 3.5KB | Microchip

The Microchip Technology PIC16C62B-04/SS is an 8-bit RISC CMOS microcontroller from the PIC16C family, integrating 3.5KB (2K x 14) of One-Time-Programmable (OTP) program memory, 128 bytes of RAM, and 22 digital I/O lines in a 28-pin SSOP package. It executes instructions at a 4 MHz clock rate from the PIC16C6x mid-range core, with most instructions completing in a single cycle for predictable deterministic control performance. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory, volatile data memory, and programmable peripherals. Within the broader taxonomy, the PIC16C62B belongs to the 8-bit MCU -> microcontroller -> embedded processor -> semiconductor IC hierarchy. OTP variants are programmed once at production or during the first board bring-up and cannot be re-programmed, which differentiates them from Flash-based PIC16F parts and makes them suitable for cost-sensitive, fixed-function, high-volume products where firmware is finalized. Key features include 22 I/O pins with individually configurable direction registers, a 20 MHz maximum operating frequency across the family (this 04-speed grade is specified for 4 MHz), an operating voltage range compatible with 5V systems, and standard PIC16C6x peripherals including timers, a watchdog timer, and a synchronous/asynchronous serial port. The device uses an external oscillator input. The 28-SSOP package has a 5.30 mm body width and is supplied in tubes for programming houses and production lines. The architecture is a Harvard-design RISC CPU with 35 single-word instructions and a 14-bit instruction word. Program branches take two cycles; all other instructions are single-cycle, so most code paths run at one instruction per four clock cycles. The 8-bit data path with 128 bytes of RAM targets modest embedded tasks such as sensor reading, simple state machines, keypad scanning, and low-rate serial bridging rather than DSP or graphics workloads. Typical applications include consumer white goods control boards, industrial sensor interfaces, simple motor drivers, HVAC auxiliary controls, security panel keypads, and battery chargers. The OTP memory is well-matched to mature designs that do not need firmware updates after release. The 28-SSOP footprint is hand-solderable but better suited to reflow processes during PCB assembly. When designing with the PIC16C62B-04/SS, plan firmware development around OTP constraints: code is finalized and burned in production, so verify all logic on equivalent Flash PIC16F parts or emulator devices before committing to the OTP mask. Use the external oscillator input with a 4 MHz crystal or resonator, and follow Microchip's recommended decoupling and reset-circuit layout guidelines. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone, including cross-references to PIC16C6x family members and PIC16F Flash equivalents that share the same SSOP-28 footprint.

PIC16C62B-04E/SO - 4MHz 8-bit OTP MCU 28-SOIC | Microchip
PIC16C62B-04E/SO

PIC16C62B-04E/SO - 4MHz 8-bit OTP MCU 28-SOIC | Microchip

The Microchip PIC16C62B-04E/SO is an 8-bit RISC microcontroller from the PIC16C mid-range family, operating at up to 4MHz with 3.5KB (2K x 14) of One-Time Programmable (OTP) program memory and 128 bytes of RAM, housed in a 28-pin SOIC package. The "-04E" suffix indicates 4MHz maximum clock and an extended automotive temperature grade of -40C to +125C, while "/SO" designates the 300-mil SOIC package with gull-wing leads suitable for surface-mount assembly. What is an OTP microcontroller? An OTP (One-Time Programmable) MCU is a microcontroller whose program memory can be written exactly once after manufacture using a device programmer; the bit cells are implemented as EPROM-style fuses rather than the floating-gate cells of flash memory. This makes OTP parts cost-optimized for high-volume production where firmware is finalized and code changes are not expected in the field, and they remain popular in automotive and appliance applications where supply continuity matters more than in-system reprogrammability. Key features of the PIC16C62B include 22 digital I/O pins, three hardware timers (Timer0, Timer1, and Timer2 with PWM), a USART/SCI serial port, a 10-bit successive-approximation ADC with 8 channels, a synchronous serial port (SSP) supporting SPI and I2C master/slave modes, and a watchdog timer with its own on-chip RC oscillator for maximum reliability. The PIC16C core executes single-cycle instructions at 200ns (4MHz clock / 4) and offers 35 single-word instructions, while the brown-out reset and power-on reset blocks protect the system against supply transients. The architecture is based on a Harvard-class RISC design with separate program and data buses, allowing instruction fetch and operand access in a single clock cycle. The 14-bit instruction word keeps the code density high for 8-bit control tasks, and the OTP EPROM cell is rated for data retention suitable for long-life industrial and automotive products. The wide 2.5V to 6.0V operating range also makes the part tolerant of unregulated supplies commonly seen in 5V and 4V battery-backed systems. Typical applications include automotive body controllers and instrument clusters, appliance control boards, sensor signal conditioning, low-end motor control loops, and industrial IO modules. The extended temperature grade (-E suffix) specifically targets under-hood automotive and outdoor industrial environments where commercial-grade parts would otherwise fail. When designing with the PIC16C62B, plan your firmware on a development-friendly part first, then burn the final code into the OTP die only after full validation. Because OTP memory cannot be erased, you must budget for a one-time programming cost per unit and choose a programmer that supports the PIC16C6x family OTP windowless devices.
