PIC16C62A-04I/SP - 8-Bit 4MHz OTP MCU 28-SPDIP | Microchip

The Microchip Technology PIC16C62A-04I/SP is an 8-bit RISC CMOS microcontroller in the PIC16C family, featuring 3.5KB (2K x 14) of One-Time-Programmable (OTP) program memory and 128 bytes of data RAM, housed in a 28-pin SPDIP (Skinny Plastic DIP) through-hole package. It runs at a maximum clock speed of 4 MHz, operates from a 5V supply, and exposes 22 I/O pins across two ports (PORTA and PORTB). An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, memory, and peripherals around an 8-bit data path. PIC microcontrollers follow a RISC (Reduced Instruction Set Computer) architecture, executing one instruction per instruction cycle (four clock cycles). The PIC16C62A belongs to the mid-range PIC16C family - itself a sub-family of Microcontrollers -> Integrated Circuits -> Semiconductors. OTP memory allows a one-time-only field programming, which is well suited to mature, low-cost, high-volume products. Key features of the PIC16C62A-04I/SP include 35 single-word instructions (only 25 are unique), a 14-bit instruction word, an 8-level deep hardware stack, an integrated Timer0 8-bit counter/timer with 8-bit prescaler, Timer1 16-bit counter/timer, Timer2 8-bit counter/timer, capture/compare/PWM (CCP) module, a 10-bit multi-channel analog-to-digital converter, synchronous serial port (SSP) supporting SPI and I2C, USART, watchdog timer with on-chip RC oscillator, and power-on reset (POR). The PIC16C62A uses a Harvard architecture with separate program and data buses, allowing instruction fetch and operand access to occur in the same cycle. The industrial-grade (-40C to +85C) operating range, indicated by the "I" suffix, makes it suitable for harsh-environment applications. The "04" speed grade corresponds to a 4 MHz maximum oscillator frequency. The device is well suited for low-to-medium complexity embedded control tasks where simple I/O, timing, and serial communication dominate. Typical applications include industrial automation control, motor control interfaces, sensor signal conditioning, simple consumer appliance controllers, HVAC control boards, and educational/hobbyist embedded platforms. The USART and SSP modules enable straightforward integration with sensors, displays, and host processors. When designing with the PIC16C62A, note that OTP memory cannot be erased or rewritten; use a windowed (JW) or Flash-based PIC16F equivalent for development and firmware iteration. Industrial temperature grade (-40C to +85C) is sufficient for most indoor and sheltered outdoor applications but does not cover automotive AEC-Q100 environments.

PIC16C62A-04I/SS

PIC16C62A-04I/SS - 8-Bit 4MHz OTP MCU 3.5KB | Microchip

The Microchip Technology PIC16C62A-04I/SS is a low-cost, high-performance CMOS OTP 8-bit microcontroller from the PIC16C family, built on Microchip's PIC RISC core architecture and housed in a 28-pin SSOP package. The device integrates 3.5 KB (2K x 14) of one-time-programmable EPROM program memory, 128 bytes of data RAM, and runs at up to 4 MHz instruction throughput. The 'I' temperature grade and industrial voltage range of 2.5V to 6.0V make it suitable for industrial control applications. A PIC16C-series 8-bit microcontroller is a RISC-based (Reduced Instruction Set Computer) single-chip computer that integrates CPU core, program memory (ROM/EPROM/Flash/OTP), data RAM, peripheral timers, capture/compare modules, a watchdog timer, an analog comparator, and I/O ports onto a single silicon die. These MCUs are designed to provide deterministic interrupt response, low power consumption, and minimal external component count for embedded control. PIC microcontrollers sit in the broader hierarchy of microcontrollers -> embedded processors -> integrated circuits, and historically dominated low-cost 8-bit embedded designs. Key features include 33 single-word instructions with 14-bit instruction width, a 200 ns instruction cycle at 4 MHz oscillator, an 8-level deep hardware stack, power-on reset, power-up timer, oscillator start-up timer, and a watchdog timer with on-chip RC oscillator for reliable operation. The device includes 22 digital I/O pins, three timers (one 8-bit Timer0 and two 16-bit Timer1/Timer2-style counters, depending on peripheral set), a 16-bit capture/compare/PWM module, a USART serial port, and a parallel slave port. Architecturally, the PIC16C62A separates program bus (14-bit wide) and data bus (8-bit wide) in a Harvard architecture, allowing simultaneous instruction fetch and operand access, which boosts throughput relative to von Neumann 8-bit MCUs of similar clock rate. The CMOS EPROM process gives the part its low-power profile: 15 uA typical at 5V/4 MHz and 1 uA typical at 3V/32 kHz standby. Typical applications include industrial control logic, automotive body electronics, appliance controllers, security system sensor interfaces, and consumer remote-control transmitters. The OTP program memory and small SSOP footprint make the PIC16C62A a fit for cost-sensitive high-volume products where firmware is final and reprogramming is not required. For prototyping or production environments requiring re-programmability, consider the PIC16F62A Flash successor. When designing with this device, note that the OTP memory is one-time programmable: a windowed JW-package variant is required for development/erase cycles, and a flash-based migration part is recommended for new designs. Verify the industrial temperature grade (-40C to +85C) and decoupling on VDD/AVSS, and ensure the MCLR reset circuit is properly pulled up to VDD.

It integrates 3.5 KB (2K x 14) of program memory, 128 bytes of RAM, and 22 digital I/O lines, organized around a RISC architecture with a fully static design that supports low-power and high-speed modes. A PIC16C6x-series 8-bit microcontroller is a RISC-based embedded controller built on low-power, high-speed CMOS EPROM/ROM technology. It belongs to the broader product family hierarchy microcontroller -> MCU -> embedded IC -> semiconductor, and is intended for applications that need deterministic instruction execution, low power draw, and a small instruction footprint. The PIC16C6x family is typically used in commercial, industrial, and extended-temperature equipment where OTP (one-time-programmable) memory is acceptable. Key features of the PIC16C62A-10/SO include a wide operating voltage range of 2.5 V to 6.0 V, with typical low-power consumption figures of 15 µA at 5 V/4 MHz and 1 µA at 3 V/32 kHz. The device is a fully static design and supports an external oscillator. Its 28-pin SOIC outline is compatible with industrial surface-mount manufacturing, and the 22 I/O pins provide ample flexibility for digital interfacing, keypad scanning, LED driving, and parallel bus applications. The PIC16C62A-10/SO uses a Harvard RISC core with a small instruction set optimized for C and assembly compilers. The 10 MHz clock combined with the PIC instruction pipeline yields roughly 5 MIPS of throughput, which is sufficient for control loops, simple sensor fusion, and human-machine interface logic. The EPROM-based program memory enables factory-programmed, high-volume, low-cost designs. Typical applications include industrial control logic, appliance control boards, automotive subsystems (non-safety), consumer electronics, security and alarm panels, and low-power sensor read-out systems. Designers choose this part for legacy 8-bit firmware reuse, OTP cost advantages, and the broad availability of PIC development tools. A primary design consideration is OTP memory: once programmed, the PIC16C62A-10/SO cannot be re-flashed in-circuit. For iterative development, prototype using a windowed or flash sibling (such as PIC16F62x) and migrate to PIC16C62A-10/SO for production. Also confirm whether the part is still recommended for new designs versus mature/legacy use.

PIC16C62A-10/SP

PIC16C62A-10/SP - 8-Bit 10MHz OTP MCU 3.5KB | Microchip

The Microchip Technology PIC16C62A-10/SP is an 8-bit CMOS RISC microcontroller from the PIC16CXX family, running at up to 10 MHz with 3.5 KB (2K x 14 words) of One-Time Programmable (OTP) 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. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory, working RAM, and peripheral interfaces on one die. Within the broader semiconductor taxonomy, MCUs sit under microcontrollers, then embedded processors, then semiconductors. The PIC16C62A specifically belongs to Microchip's mid-range PIC16C family, which uses a 14-bit instruction word and Harvard architecture to deliver deterministic single-cycle execution for most instructions, making these parts a workhorse for cost-sensitive industrial and consumer control. Key features of the PIC16C62A-10/SP include a 10 MHz maximum operating frequency (the "-10" speed grade), 22 general-purpose I/O pins, 128 bytes of data RAM, integrated I²C and SPI synchronous serial ports, a 10-bit-resolution capture/compare/PWM module, an 8-bit timer/counter, a watchdog timer with on-chip RC oscillator, brown-out reset, power-on reset, and an operating voltage range of 2.5 V to 6.0 V. The OTP program memory enables low-cost, one-time field programming for high-volume production runs. Architecturally, the device separates program and data memory spaces (Harvard) and uses a 14-bit-wide instruction word with only 35 single-word instructions, simplifying code generation in assembly while supporting C compilers via Microchip's MPLAB XC8 toolchain. The high-performance RISC core executes most instructions in one instruction cycle (200 ns at 20 MHz, 400 ns at 10 MHz), and the 8-level hardware stack plus on-chip oscillator reduce external component count. Typical applications for the PIC16C62A-10/SP include industrial control and sensor interfacing, automotive body and chassis subsystems, appliance motor control, low-cost remote sensor nodes, HVAC damper and valve control, and battery-powered instrumentation. Its combination of OTP memory, through-hole SPDIP package, and wide operating voltage makes it well suited to legacy designs and field-replaceable modules where socketed reprogrammability is not required. When designing with this part, note that OTP memory cannot be erased, so firmware must be fully validated before programming. Programming voltage (typically 13 V on the VPP/MCLR pin) is required during device programming via Microchip's MPLAB PM3 or ICD tools. For new designs, Microchip designates the PIC16C62A as "Not Recommended for new designs" (NRND) and recommends the flash-based PIC16F62x family as the modern equivalent.

PIC16C62A-10E/SP

PIC16C62A-10E/SP - 8-bit 10MHz 3.5KB EPROM MCU | Microchip

The Microchip Technology PIC16C62A-10E/SP is an 8-bit CMOS RISC microcontroller based on the PIC16C6X core, integrating 3.5KB (2K x 14) of one-time programmable (OTP) EPROM program memory and 128 bytes of RAM in a 28-pin SPDIP through-hole package. It operates from a 3.0V to 6.0V supply, runs at up to 10 MHz, and delivers 22 digital I/O pins alongside on-chip peripherals including an 8-bit timer/counter, a 16-bit timer/counter, an 8-bit A/D converter (depending on die revision), a Capture/Compare/PWM module, and both I2C and SPI serial interfaces. An 8-bit microcontroller is a single-chip computer built around an 8-bit data bus, a small instruction set, and integrated memory plus peripherals. The PIC16C62A belongs to the PIC16C family of OTP-EPROM-based mid-range microcontrollers, which sits in the hierarchy: PIC16C -> mid-range PIC family -> 8-bit PIC microcontrollers -> microcontrollers (MCU) -> embedded semiconductors. These devices trade large flash densities for low unit cost and proven CMOS reliability in industrial control, instrumentation, and legacy equipment designs. Key features include 35 single-word instructions, all executing in one instruction cycle except for program branches (two cycles), DC to 10 MHz clock input, and typical active current of approximately 2 mA at 5 V/4 MHz. Power-saving modes include a standby mode drawing roughly 1 uA typical at 3 V/32 kHz, and a low-power Run mode useful for battery-powered instruments. The device supports commercial, industrial, and extended temperature grades (the E suffix denotes the Extended -40C to +125C grade in this part number). Architecturally, the PIC16C62A uses a Harvard-style RISC core with separate program and data buses, a 14-bit-wide instruction word, and a hardware multiplier-free ALU optimized for deterministic single-cycle execution. The integrated EPROM program memory is one-time programmable, requiring a windowed package variant for erasure, and is suited to mature production runs where firmware is fixed. Brown-out reset, watchdog timer, and power-on reset are integrated, reducing external component count. Typical applications include industrial motor control, HVAC actuation, security alarm panels, automotive body electronics (where extended temperature is required), embedded control of legacy appliances, and instrumentation front-ends requiring I2C/SPI glue logic. Designers migrating from PIC16C62 to PIC16C62A benefit from the enhanced timer architecture and improved oscillator tolerance. When designing with this part, mind the OTP limitation: firmware must be fully validated before programming, as the EPROM cannot be reprogrammed in-circuit. Always include a decoupling capacitor pair (0.1 uF plus bulk 10 uF) within 5 mm of the VDD/VSS pins to suppress switching noise that can corrupt A/D readings on noise-sensitive analog inputs.

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.

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.

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.

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.

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 - 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.

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. The /JW package should be stored in opaque tape when not being erased - UV exposure from fluorescent lighting can degrade EPROM cells over time.

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.

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.

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.

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
PIC16C62AT-10E/SS

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
PIC16C62AT-20E/SS

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.

PIC16C62AT-20I/SO - 8-Bit 20MHz OTP MCU 3.5KB | Microchip
PIC16C62AT-20I/SO

PIC16C62AT-20I/SO - 8-Bit 20MHz OTP MCU 3.5KB | Microchip

The Microchip Technology PIC16C62AT-20I/SO is an 8-bit PIC16C-series RISC microcontroller featuring a 20 MHz core speed, 3.5 KB (2K x 14) of One-Time Programmable (OTP) program memory, 128 bytes of RAM, and 22 general-purpose I/O pins, housed in a 28-pin SOIC (0.295", 7.50 mm width) package supplied on tape and reel. 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. This page synthesizes distributor pricing, drop-in alternatives within the same 28-SOIC footprint, and engineering design notes that the manufacturer datasheet alone does not provide.
