The Microchip Technology PIC16C622T-04E/SS is an 8-bit RISC EPROM-based CMOS microcontroller from the PIC16C family, offering 3.5KB (2K x 14) of One-Time Programmable (OTP) program memory, 128 bytes of RAM, and 13 general-purpose I/O pins in a 20-pin SSOP package. The "-04" speed grade denotes a 4MHz maximum operating frequency, and the "E" suffix indicates an extended industrial temperature grade of -40C to +125C, making this part suitable for harsh-environment embedded designs that must operate across wide thermal ranges. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory, working RAM, and peripheral interfaces into one package. Within the broader taxonomy of semiconductors, an MCU belongs to the digital logic / microcontroller class, and the PIC16C series occupies the mid-range 8-bit tier of Microchip's PIC portfolio, offering RISC architecture with a 14-bit instruction word optimized for compact, deterministic control code. OTP program memory allows the device to be programmed once during manufacturing, which lowers unit cost versus flash-based MCUs and is well suited to high-volume, fixed-function consumer and industrial products. Key features of the PIC16C622T-04E/SS include the 14-bit instruction set, 35 single-word instructions (most single-cycle), a hardware multiplier, Brown-out Detect/Reset, Power-On Reset (POR), Watchdog Timer (WDT) with its own on-chip RC oscillator, an analog comparator, a programmable voltage reference, and a Capture/Compare/PWM (CCP) module. The wide 2.0V to 6.0V supply range allows battery-backed or 5V-rail designs, and the 20-SSOP outline saves board area versus a 20-pin PDIP alternative. Architecturally, the PIC16C622 uses a Harvard bus with separate program and data paths and a 2-stage pipeline. On-chip peripherals include a 16-bit timer/counter (TMR1) optionally operable in sleep mode with an external crystal, an 8-bit timer/counter (TMR0) with 8-bit prescaler, and synchronous serial port (SSP) for SPI / I2C master-slave communication. Two analog comparators with a programmable reference voltage block add signal-conditioning capability without external op-amps. Typical applications include white-goods and appliance controls, low-end remote controls, sensor signal conditioning with on-chip comparators, simple sensor-front-end nodes, battery chargers, automotive body controllers, lighting ballasts, and industrial control subsystems where cost dominates over reprogrammability. The extended temperature grade extends use to under-hood and outdoor enclosures. When designing with this device, ensure that the chosen emulator/programmer (PICMASTER, MPLAB PM3, or PRO MATE II) supports the PIC16C62x OTP windowed/extended parts, and budget for a 25 mA / 6 V absolute maximum on VDD plus proper decoupling with 0.1 uF + 10 uF bulk capacitors. Pin-compatible PIC16C62x family members exist in the same 20-SSOP package, simplifying last-time buys and PCB reuse.

Within the embedded-system hierarchy, an MCU sits between a fixed-logic ASIC (full custom silicon) and a microprocessor (which requires external memory and peripherals). The PIC16C family uses a RISC Harvard architecture with a 14-bit instruction word, separate program and data buses, and a deterministic instruction cycle that simplifies real-time control. The OTP variant is intended for volume production where firmware is finalized; for prototyping and field updates, the FLASH-based PIC16F family is generally preferred. Key features include a hardware 8-bit timer/counter with a prescaler, an analog comparator module with programmable reference, watchdog timer with on-chip RC oscillator for reliable resets, power-saving SLEEP mode, in-circuit serial programming (ICSP) interface, and 25 mA source/sink capability per pin to drive LEDs and small relays directly. The architecture delivers 5 MIPS at 4 MHz and provides 35 single-word instructions. The device's analog comparator makes it suitable for battery-voltage monitoring and threshold-based control loops without an external op-amp. Power-on reset, brown-out detection and the wide operating voltage window reduce external component count in cost-sensitive designs. Typical applications include appliance control, security-system keypads, IR remote controls, sensor signal conditioning, automotive body electronics (non-safety), and battery chargers. The industrial temperature window also supports factory-floor sensor interfaces. When designing with this part, note that PIC16C OTP devices are windowless and cannot be reprogrammed. Use a PIC16F equivalent for development and migrate firmware to the 'C' OTP device for production to avoid wasted engineering samples. This page synthesizes distributor pricing, parametric drop-in alternatives and practical design considerations not collected in any single manufacturer datasheet, helping engineers evaluate the PIC16C622T-04I/SO against modern FLASH-based PIC16F and PIC16F1xxx alternatives.

It operates at up to 20 MHz clock speed with a 5V supply and is fabricated using CMOS technology. The device is supplied in tape-and-reel packaging as indicated by the 'T' suffix, making it suitable for high-volume SMT assembly. A microcontroller (MCU) is a single-chip computer containing a CPU core, program memory (ROM/Flash/OTP), data memory (RAM), and programmable I/O peripherals. The PIC16C622 belongs to the mid-range 8-bit PIC family, sitting in the hierarchy: 8-bit MCU -> RISC MCU -> PIC16C -> mid-range PIC microcontroller -> embedded controller. It uses a Harvard architecture with separate program/data buses, an accumulator-based ALU, and a 14-bit instruction word. Key features include 35 instructions, 8-level hardware stack, 4 oscillator modes (RC, LP, XT, HS), two 8-bit timers (Timer0, Timer2) and one 16-bit timer (Timer1), a 14-bit capture/compare/PWM module, an analog comparator, a watchdog timer with on-chip RC oscillator, and an in-circuit serial programming (ICSP) interface. The 18-SOIC package (7.50 mm body width) is the industry-standard surface-mount outline for this MCU family. The PIC16C622's architecture is optimized for low-cost, deterministic real-time control with single-cycle instruction execution (except branches). Its RISC instruction set provides predictable timing for embedded control loops, while the OTP program memory is well-suited for high-volume consumer and industrial products where program changes are not expected after production. Typical applications include appliance control, sensor signal conditioning, low-end motor control (DC brushed), HVAC fan controllers, security alarm keypads, simple LED drivers, battery chargers, and remote-control transmitters. The 13 I/O pins can directly drive LEDs, relays, or interface to sensors via the analog comparator. Industrial temperature grade parts are also available for harsher environments. When designing with this part, ensure a 1 kΩ pull-down on MCLR/VPP and place a decoupling capacitor (typically 0.1 µF) close to VDD. Because OTP cannot be re-programmed, verify firmware on a windowed or flash-equipped equivalent (e.g., PIC16F622) before committing to production. The 20 MHz maximum clock requires a 5V supply; at lower VDD the maximum frequency is derated.

Typical applications include appliance control (white goods, HVAC actuators, washing machines), industrial sensor interface boards, low-cost automotive subsystems (non-safety), battery chargers, smart metering front-ends, lighting ballasts, and consumer white goods with analog comparators. The internal comparators can directly interface with sensors, replacing external op-amps in threshold-detection circuits. When designing with this part, note the OTP program memory requires a mask/OTP programming step at production; use a flash equivalent (PIC16F62x family) during prototyping for code iteration, then port back for cost-down production. Add 0.1 µF + 10 µF decoupling close to VDD/VSS.

The Microchip Technology PIC16C622T-20I/SO is a CMOS 8-bit OTP-based microcontroller from the PIC16C6x family, featuring 3.5KB (2K x 14) of one-time-programmable program memory, 128 bytes of RAM, and 13 I/O pins in a surface-mount 18-pin SOIC (0.295", 7.50mm) wide-body package. It operates from a supply voltage of 2.5V to 6.0V (commonly 3.3V or 5V), runs instruction cycles at 20 MHz with a 200 ns instruction cycle, and is qualified to the industrial temperature grade of -40C to +85C. The device ships on tape-and-reel (suffix "T"). Background: A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, RAM, and peripherals (I/O, timers, interrupts, communication interfaces) into one package. The PIC16C6x family is built on Microchip's RISC-based 8-bit PIC architecture with a 14-bit instruction word, separating it from the PIC16F (flash) and PIC16C (OTP/EPROM/ROM) lineages. MCUs in this class are widely used as the lowest-cost embedded controllers in cost-sensitive industrial, consumer, and automotive-body products. Key features of the PIC16C622T-20I/SO include a precision analog comparator, one 8-bit timer (TMR0) with an 8-bit programmable prescaler, a watchdog timer with its own on-chip RC oscillator for reliable resets, an internal MCLR reset path, a 4 MHz internal RC oscillator option, and an enhanced capture/compare/PWM (CCP) peripheral. The device provides 13 bidirectional I/O pins with high-current sink/source, plus power-on reset (POR), brown-out reset, and in-circuit serial programming (ICSP) capability through two pins. Technically, the PIC16C622 implements a Harvard architecture with separate program and data buses, a 14-bit instruction set, and a 35-instruction RISC core. Its 2-stage instruction pipeline delivers 5 MIPS at 20 MHz. Operating from 2.5V to 6.0V across the full industrial temperature range, the device is suitable for battery- and line-powered designs alike, and the OTP memory allows one-time factory or production programming. Typical applications include appliance controllers, security-system keypads, motor-control front-ends, low-end instrumentation, and battery-powered sensor interfaces. The on-chip analog comparator and CCP peripheral also suit closed-loop fan, pump, and solenoid drivers. Designers should plan for the one-time-programmable memory model: code is locked at production programming and cannot be firmware-updated in-circuit beyond ICSP. Always reserve an I/O pin pair for ICSP, and verify retention/longevity assumptions for OTP programming windows on each batch. This page consolidates current distributor pricing, package-level cross-references, and engineering design notes that go beyond what the manufacturer datasheet alone exposes, giving procurement and design engineers a single reference point.

PIC16C62A-04/SP

PIC16C62A-04/SP - 8-bit 4MHz 3.5KB OTP MCU | Microchip | 28-SPDIP

The Microchip Technology PIC16C62A-04/SP is an 8-bit CMOS OTP (One-Time-Programmable) RISC microcontroller in the PIC16C family, built around the PIC16C6x core and offered in a 28-pin SPDIP (Skinny Plastic DIP) through-hole package. It operates at a maximum clock speed of 4 MHz, integrates 3.5 KB of OTP program memory (organized as 2K × 14 words), and includes 128 bytes of RAM with 22 general-purpose digital I/O pins. The device uses CMOS EPROM/ROM technology, is fully static, and supports a wide operating voltage range up to 6.0 V across commercial, industrial, and extended temperature grades. An 8-bit OTP microcontroller is a single-chip computer built on an 8-bit data path with non-volatile program memory that can be written exactly once by the user. These devices sit inside the broader hierarchy of microcontrollers → embedded processors → semiconductor ICs, and historically dominated cost-sensitive, mid-volume embedded control applications before Flash-based MCUs became economical. The PIC16C family is part of Microchip's PIC16 → PICmicro → 8-bit MCU taxonomy, which uses a RISC-style instruction set designed for deterministic, single-cycle execution on most opcodes. Key features of the PIC16C62A-04/SP include 35 single-word instructions, a 14-bit instruction word, 8-bit data path, 4 MHz oscillator input, on-chip peripherals such as timers, a watchdog timer, and a synchronous/asynchronous serial port (SSP). Power consumption is a notable feature: typical supply current is approximately 15 µA at 5 V / 4 MHz and around 1 µA at 3 V / 32 kHz, supporting battery-friendly designs. The 28-SPDIP package provides a 0.300 inch (7.62 mm) row spacing, which is convenient for prototyping, breadboarding, and educational use. Architecturally, the PIC16C62A-04/SP uses a Harvard memory layout (separate program and data buses) and a fully static design that allows the clock to be stopped without losing register state. Its OTP EPROM cell technology is the main reason the part is positioned at lower price points than equivalent Flash-based PIC16F devices, but it also means firmware cannot be rewritten in-circuit; programming is performed with a device programmer such as the MPLAB PM3. Typical applications include blood-pressure monitors and other low-power medical instruments, appliance controls, automotive body and comfort subsystems, consumer electronics, security and alarm panels, and industrial sensor interfaces. The combination of low power consumption, deterministic core, and DIP package makes the PIC16C62A-04/SP a frequent choice for legacy designs, hobby projects, and through-hole industrial control modules. When designing with this part, the OTP memory limitation is the most important trade-off: once programmed, the device cannot be re-flashed. Engineers should validate firmware with a socketed or windowed version, or consider the pin-compatible PIC16F62A / PIC16F72 family for in-circuit reprogrammability. Decoupling, oscillator layout, and MCLR reset hardware should follow Microchip's PIC16C6x reference design recommendations. This page synthesizes distributor pricing from DigiKey and Mouser, drop-in same-package alternatives, and practical design notes that are not collected in the manufacturer datasheet PDF, helping engineers select, source, and qualify the part quickly.

The part integrates 3.5 KB of one-time-programmable (OTP) EPROM program memory and 128 bytes of RAM, with 22 digital I/O pins, a 14-bit instruction word, and a Harvard architecture optimized for deterministic interrupt response. The "04" speed grade denotes a 4 MHz maximum clock, while the "E" suffix indicates the Extended operating temperature range (-40C to +125C) suitable for industrial and automotive-grade environments. An 8-bit microcontroller (MCU) is a small single-chip computer built around an 8-bit data path and a von Neumann or Harvard instruction set, integrating CPU core, program memory, RAM, timers, and I/O peripherals onto one die. Within the broader taxonomy, the PIC16C62A belongs to Microchip's PIC16C mid-range family, which sits between the baseline PIC10/12/16 families and the high-performance PIC18 family. These OTP-EPROM microcontrollers are part of the power management and embedded control semiconductor category, historically used wherever deterministic real-time response, low power, and high code density matter more than raw computational throughput. Key features of the PIC16C62A-04E/SO include low-power CMOS EPROM/ROM technology with a fully static design that allows the clock to be stopped without losing state, a wide operating voltage range of 2.5 V to 6.0 V (per family specifications), and typical active current of 2 mA at 5 V / 4 MHz. Power-saving sleep mode draws as little as 1 uA typical at 3 V / 32 kHz, making the part suitable for battery-backed or sleep-dominated applications. The device offers programmable code protection, an 8-bit timer/counter with optional prescaler, a watchdog timer with its own on-chip RC oscillator, and a synchronous serial port (SSP) supporting SPI and I2C master/slave modes. Architecturally, the PIC16C62A employs Microchip's mid-range 14-bit RISC instruction set with 35 single-word instructions, where most instructions execute in a single instruction cycle (4 oscillator clocks). The 8-level deep hardware stack, two file select registers, and direct/indirect/inherent addressing modes give C programmers and assembly engineers flexible control over code placement. The Harvard architecture separates program and data buses so the CPU can fetch the next instruction while reading or writing data memory, eliminating von Neumann bottlenecks. Typical applications for the PIC16C62A-04E/SO include industrial control and sensor interfacing, automotive body and chassis subsystems (Extended temperature grade), consumer appliance controllers, HVAC equipment, low-end security and alarm panels, and remote sensor nodes that benefit from OTP cost savings in high-volume production. Its combination of OTP EPROM, low power, and 22 I/O pins makes it well suited for cost-sensitive embedded applications that have stabilized firmware. When designing with this part, note that OTP EPROM cannot be re-programmed in-circuit - firmware bugs require a new device - so plan for a flash-based PIC16F equivalent during development and prototyping. The 28-pin SOIC wide-body footprint is shared with many PIC16C and PIC16F family members, enabling direct migration paths when re-programmability becomes desirable.

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.

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.

PIC16C62A-20E/SS

PIC16C62A-20E/SS - 8-Bit 20MHz OTP MCU, 3.5KB EPROM | Microchip

The Microchip Technology PIC16C62A-20E/SS is an 8-bit CMOS EPROM/ROM-based microcontroller in the PIC16C family, featuring a 20MHz maximum clock speed, 3.5KB (2K x 14) of One-Time Programmable (OTP) program memory, and 128 bytes of RAM, housed in a 28-pin SSOP package. 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.
