PIC16C622T-20E/SS - 8-Bit 20MHz OTP MCU, 3.5KB | Microchip

The Microchip Technology PIC16C622T-20E/SS is an EPROM-based 8-bit CMOS microcontroller from the PIC16C family, operating at up to 20 MHz with 3.5 KB (2K x 14) of One-Time Programmable (OTP) program memory and 128 bytes of RAM, housed in a 20-pin SSOP (5.30 mm) package supplied on tape and reel. What is an 8-bit OTP microcontroller? An 8-bit OTP microcontroller is a small, low-cost single-chip computer built around an 8-bit data path and a one-time-programmable (non-erasable) program memory. Within the broader taxonomy it is a microcontroller -> embedded controller -> semiconductor device. The PIC16C series uses Microchip's RISC Harvard architecture, which separates program and data buses to allow simultaneous fetch and execute, delivering deterministic instruction timing. OTP parts target cost-sensitive, low-volume production where field re-programmability is not required. The device features two analog comparators with programmable on-chip voltage reference, 13 digital I/O pins, a 20 MHz internal/external oscillator option, and an instruction set of only 35 single-word instructions. The two comparators make it well suited for simple mixed-signal tasks such as threshold detection, battery monitoring, and feedback loops without external analog ICs. Power-saving features include a Watchdog Timer with its own on-chip RC oscillator for reliable operation and a SLEEP mode for low quiescent current applications. Operating from 3.0 V to 6.0 V across the -40 C to +125 C extended temperature range, the PIC16C622T-20E/SS targets industrial and automotive-grade environments. The 'E' suffix denotes the extended temperature grade while 'T' indicates tape and reel packaging and 'SS' denotes the 20-SSOP form factor. The 20 MHz clock delivers 5 MIPS of throughput, adequate for control loops, sensor interfacing, and user-interface logic. Typical applications include battery chargers, SMPS control, motor control feedback, security systems, appliance control, automotive sensor interfacing, and general-purpose embedded control. The two on-chip comparators eliminate the need for an external op-amp in many cost-sensitive designs. When designing with the PIC16C622T-20E/SS, note that OTP memory cannot be erased or rewritten after programming. Ensure firmware is fully validated before burning. A 100 nF decoupling capacitor close to VDD/SS is recommended for noise immunity.

PIC16C622T-20I/SO

PIC16C622T-20I/SO - 8-bit OTP MCU 3.5KB 20MHz 18-SOIC

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.

It integrates 3.5 KB of program memory (2K x 14), 128 bytes of RAM, and 13 digital I/O pins, all in a compact 5.30 mm wide SSOP-20 outline. The "T" suffix denotes tape-and-reel packaging and "I" indicates the -40°C to +85°C industrial temperature grade. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, data RAM, and configurable peripheral I/O on one IC. The PIC16C family uses a RISC architecture with 35 single-cycle instructions, which delivers deterministic throughput at low power. Within the broader category hierarchy, the PIC16C622 belongs to: microcontroller -> embedded controller -> semiconductor IC. The OTP variant is intended for low-cost production where firmware is finalized and field re-programmability is not required. Key features include a 20 MHz maximum clock speed, 14-bit instruction word, 8-bit data path, 13 bidirectional I/O pins, a hardware 8-bit timer/counter (TMR0), a Watchdog Timer with independent on-chip oscillator, power-on reset, brown-out detection, and programmable code protection. The device operates from 2.5 V to 5.5 V and draws a typical 2 mA at 5 V / 20 MHz, with < 1 µA standby current for battery-friendly designs. The PIC16C622T-20I/SS employs a Harvard architecture with separate program and data buses, allowing instruction fetch and operand read to occur in a single clock cycle. Its CMOS OTP cell array and CMOS EPROM technology provide robust operation, and the on-chip RC oscillator option reduces external component count. An analog comparator module is integrated, eliminating the need for an external op-amp in many signal-conditioning interfaces. Typical applications include consumer appliance control, sensor signal conditioning with on-chip comparator, low-end remote control transmitters, white goods user interfaces, and industrial control modules where small form factor and cost dominate over flash reprogrammability. The 20-pin SSOP footprint suits compact PCBs and pick-and-place assembly lines. When designing with this part, plan OTP programming into the production flow (programmer required per unit) and reserve brown-out reset configuration in the configuration word. For new designs, Microchip generally recommends migrating to the flash-based PIC16F family for development flexibility, while reserving the OTP C-variant for cost-optimized mature products.

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

Key features include a wide operating voltage range of 2.5 V to 6.0 V, commercial, industrial, and extended temperature grades, and ultra-low power consumption of 15 uA typical at 5 V/4 MHz and 1 uA typical at 3 V/32 kHz. The 28-SSOP package supports surface-mount assembly and is footprint-compatible with the broader PIC16C62/62A/63/64/65/66/67 family. The architecture uses a Harvard design with separate program and data buses, a 14-bit instruction word, and a 35-instruction set that simplifies code generation in assembly or C. Typical applications include appliance control, HVAC interfaces, simple sensor readouts, automotive body controllers (where qualified), remote controls, and low-cost industrial sensor nodes. Designers select the PIC16C62A-04/SS when the program size is fixed at production time and total system cost must be minimized without sacrificing Microchip's mature toolchain (MPLAB, MPASM, ICD). When designing, confirm the OTP memory limitation upfront - once programmed, the device cannot be re-programmed in-circuit. For prototyping, use the PIC16F62x equivalent or the PIC16C62A JW windowed version. Plan decoupling and oscillator layout per Microchip AN588.

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.

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.

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.

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 - 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 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.

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.

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.

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.

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.

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

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.

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