PIC16C622A-20E/P

PIC16C622A-20E/P - 3.5KB OTP 8-bit MCU, 18-DIP | Microchip

The Microchip Technology PIC16C622A-20E/P is an EPROM-based 8-bit CMOS microcontroller from the PIC® 16C family, delivering 3.5KB (2K x 14) of one-time-programmable (OTP) program memory, 128 bytes of RAM, and 13 I/O pins in a through-hole 18-pin DIP package. It operates up to 20 MHz from a 5V supply and is rated for the extended automotive temperature grade. The part suffix "-20E" denotes 20 MHz maximum clock and the "E" industrial/automotive temperature grade (-40C to +125C), with the "/P" package code identifying the 0.300-inch-wide PDIP-18 plastic DIP. A PIC (Peripheral Interface Controller) microcontroller is a Harvard-architecture RISC processor with separate program and data buses, optimized for deterministic real-time embedded control. The PIC16C622A belongs to the mid-range PIC14-instruction family, uses a 14-bit instruction word, and integrates analog peripherals including a comparator module and a capture/compare/PWM (CCP) block that simplifies closed-loop control. In the wider taxonomy it sits as: PIC16C622A -> PIC16C62x family -> PIC16 mid-range -> PICmicro 8-bit MCU -> embedded microcontroller -> semiconductor. The OTP EPROM cell enables fast prototype-to-production migration for cost-sensitive and automotive applications. Key features include 3.5KB OTP program memory, 128 bytes of data RAM, 13 digital I/O pins, an integrated analog comparator, a 16-bit timer/counter with capture/compare/PWM, an 8-bit timer/counter, a 5-channel 8-bit ADC, and a watchdog timer with its own on-chip RC oscillator. Power-managed Sleep mode and a hardware Universal Synchronous/Asynchronous Receiver/Transmitter (USART/SCI) round out the peripheral set. Compared with the earlier PIC16C622, the "A" silicon revision improves brown-out behaviour and ESD robustness. Architecturally the device uses a 14-bit instruction word, two-cycle instruction execution for branches and a four-cycle oscillator start-up from Power-on Reset. Its low-power CMOS design draws only microampere-level Sleep currents while preserving full register retention, making it a strong fit for battery-backed and automotive applications where quiescent draw matters. Typical applications include automotive body controllers and instrument clusters, HVAC fan control, appliance user-interface panels, low-end security keypads, and remote sensor transmitter nodes. The wide -40C to +125C automotive temperature range makes it particularly well-suited to under-hood and dashboard electronics that must survive harsh thermal environments. When designing with the PIC16C622A-20E/P, place a 100 nF decoupling capacitor within 5 mm of VDD and reserve the ICSP programming footprint even on production boards - OTP parts must be programmed once, and in-system programming access greatly simplifies rework. Be aware that OTP cannot be erased, so design firmware carefully before committing to volume programming.

PIC16C622A-20E/SO

PIC16C622A-20E/SO - 8-Bit 20MHz 3.5KB OTP MCU 18-SOIC | Microchip

The Microchip Technology PIC16C622A-20E/SO is a CMOS OTP-based 8-bit microcontroller from the PIC16C family, delivering 20 MHz maximum operating frequency with 3.5 KB (2K x 14) of One-Time-Programmable program memory and 128 bytes of RAM in an 18-pin SOIC (0.295 inch / 7.50 mm body width) package. The -20E speed grade specifies a 20 MHz clock with the Extended industrial temperature range (-40C to +125C), and the /SO suffix denotes the wide-body SOIC-18 surface-mount package. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, memory (ROM/RAM), timers, I/O peripherals, and interrupt logic on one die. The PIC16C family uses a RISC (Reduced Instruction Set Computer) architecture with only 35 single-word instructions, allowing most instructions to execute in a single 200 ns instruction cycle at 20 MHz. MCUs belong to the broader category of microcontrollers -> embedded processors -> semiconductors, and serve as the central control element in countless embedded systems. Key features of the PIC16C622A include 13 digital I/O pins, an integrated analog comparator module, two 8-bit timers (Timer0, Timer2) and one 16-bit timer (Timer1), a Watchdog Timer with its own on-chip RC oscillator, an 8-bit parallel slave port, and an internal/external interrupt structure. The device operates from 2.5 V to 5.5 V and supports in-circuit serial programming (ICSP) via its RB6/RB7 pins. The PIC16C622A uses a Harvard architecture with separate program and data buses, an accumulator-based ALU, and a hardware stack 8 levels deep. Its CMOS process yields very low power consumption (typical < 2 mA at 5 V, 4 MHz), and the SLEEP power-down mode reduces quiescent current to the microampere range, making it suitable for battery-backed or energy-conscious designs. Typical applications include appliance controls, automotive body electronics (non-safety), sensor signal conditioning, LED driving, motor control PWM, low-end remote controls, and industrial metering. The integrated analog comparator is particularly useful for zero-crossing detection, battery voltage monitoring, and sensor threshold detection. When designing with this part, note that OTP memory can be programmed only once; engineers must commit the firmware before final assembly. Use sockets or adapt the design to a Flash equivalent (PIC16F62x family) for prototyping. Decouple VDD/VSS with a 100 nF ceramic capacitor placed within 5 mm of the package pins, and reserve RB6/RB7 for ICSP to keep in-field firmware updates possible during development.

The device operates at a maximum clock speed of 20 MHz across a 2.5 V to 5.5 V supply range and is housed in a 20-pin SSOP package (5.30 mm body width, 0.209 inch) with an industrial -40C to +125C operating temperature range. The 'E' suffix denotes the extended industrial temperature grade, while 'SS' denotes the 0.209" SSOP package option. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, RAM, non-volatile program memory, and peripheral I/O on one die. OTP microcontrollers ship with one-time-programmable EPROM for code storage and are intended for low-to-medium volume production or evaluation where re-programmability is not required. Within the broader semiconductor hierarchy, MCUs sit under microcontrollers, embedded processors, and semiconductors, and serve as the compute core for billions of low-power edge and consumer devices. The PIC16C622A is part of Microchip's mid-range PIC16C family, originally introduced in the 1990s and still used for long-lifecycle industrial and legacy designs. Key features include a RISC architecture with 35 single-cycle instructions, an internal oscillator option, two analog comparators with programmable reference, a watchdog timer, and power-on reset. The PIC16C622A delivers deterministic single-cycle instruction execution and Harvard architecture separation of program and data buses for predictable interrupt latency, which simplifies real-time control firmware. Technical depth: the PIC16C622A uses a Harvard architecture with separate 14-bit program and 8-bit data paths, supported by a 2-level hardware stack and 8-level deep software stack. The integrated comparators can be configured for analog signal conditioning, while the 13 I/O pins source or sink up to 25 mA per pin, enabling direct LED drive without external transistors. Typical applications include industrial control, appliance control, security and access panels, simple sensor interfaces, and automotive body electronics where extended-temperature operation is required. Design tip: because the PIC16C622A is OTP and not re-programmable in-circuit, plan your firmware revision strategy carefully. Use a windowed (JW) or Flash-based PIC16F variant during development and migrate to PIC16C622A only for locked production firmware.

PIC16C622A-20I/P

PIC16C622A-20I/P - 8-Bit 20MHz 3.5KB OTP MCU 18-PDIP | Microchip

The Microchip Technology PIC16C622A-20I/P is an EPROM-based 8-bit CMOS RISC microcontroller belonging to the PICmicro mid-range family, operating at up to 20 MHz clock input with a 200 ns instruction cycle. It integrates 3.5 KB (2K x 14 words) of one-time-programmable (OTP) program memory, 128 bytes of RAM, and 13 digital I/O lines, all housed in an 18-pin PDIP (Plastic DIP) through-hole package. The -20I/P suffix denotes 20 MHz maximum frequency, industrial temperature grade (-40C to +85C), and PDIP packaging. An MCU (microcontroller) is a single-chip computer containing a CPU core, program memory, data memory, and programmable I/O peripherals. The PIC16C62X family falls within the 8-bit PIC RISC architecture hierarchy: 8-bit MCU -> PIC RISC -> PIC16C mid-range -> PIC16C62X sub-family -> peripheral-rich EPROM/OTP devices. Within Microchip's portfolio, OTP EPROM parts bridge early-development ROM-based designs and field-programmable Flash parts, providing fixed-program memory at lower cost than windowed EPROM. Key features include only 35 single-cycle instructions to learn, 200 ns instruction execution (except two-cycle branches), 13 I/O pins with individual direction control, a watchdog timer, a 16-bit timer/counter with 8-bit prescaler, and an 8-bit A/D converter channel set. The -I industrial temperature grade makes this part suitable for factory-floor and outdoor enclosures, while the -20 speed grade supports deterministic control loops at kHz-to-MHz rates. The OTP memory architecture means firmware is permanently written during production programming. The PIC16C622A uses a Harvard architecture with separate program and data buses, allowing instruction fetch and operand access in the same cycle. The 14-bit instruction word and 8-bit data path are characteristic of PIC mid-range cores, providing higher code density than 8-bit CISC architectures for byte-oriented control code. Industrial peripherals such as capture/compare/PWM (CCP) and USART are not present on this specific variant, keeping the die compact for cost-sensitive applications. Typical applications include appliance control, sensor signal conditioning, low-end user interfaces, LED driving, small motor control, and white-goods timing. The 18-pin PDIP form factor suits breadboard prototyping, legacy through-hole assemblies, and educational/training kits where socketed replacement aids debugging. When designing, note that OTP memory cannot be reprogrammed, so firmware verification before programming is critical. Industrial -I temperature grade allows operation from -40C to +85C; for extended -40C to +125C operation choose a -E grade variant or a Flash-based PIC16F equivalent. This page consolidates distributor stock, drop-in replacements, and design guidance that the manufacturer datasheet alone does not present.

PIC16C622A-20I/SO - 8-Bit 20MHz OTP MCU 3.5KB | Microchip

The Microchip Technology PIC16C622A-20I/SO is an 8-bit CMOS RISC microcontroller from the PIC16C family, featuring 3.5KB (2K x 14) of One-Time Programmable (OTP) program memory, 128 bytes of RAM, and 13 I/O pins, operating at up to 20 MHz clock input with a 200 ns instruction cycle, all housed in an 18-pin SOIC package rated for the industrial -40C to +85C temperature range. The device delivers 35 single-cycle instructions (200 ns each), with only program branches being two-cycle (400 ns), enabling efficient deterministic control loops in embedded designs. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory (ROM/Flash/OTP), volatile data memory (RAM), and programmable peripheral I/O on one die, designed to execute firmware that interacts with sensors, actuators, and communication buses in real time. Within the broader semiconductor taxonomy, MCUs sit under microcontrollers -> microprocessors -> logic ICs -> integrated circuits (ICs). The PIC16C mid-range family uses a Harvard RISC architecture with a 14-bit instruction word optimized for compact code density, distinguishing it from the PIC16F flash family and the PIC18 advanced family. Key features of the PIC16C622A include a wide 2.5V to 5.5V operating voltage range (enabling both 3.3V and 5V systems), two analog comparators, internal oscillator option, and 128 bytes of data RAM. The 8-bit timer/counter, watchdog timer, and programmable code protection support robust fault-tolerant firmware. Industrial temperature grade and 1000 erase/write cycle endurance on OTP (limited; see datasheet) align with high-reliability embedded requirements. The SOIC-18 package is a surface-mount variant with 0.300 inch body width for industrial PCB assembly. This device uses CMOS EPROM-based technology with a 14-bit instruction word and an 8-bit data path, consuming under 2 mA typical at 5V/4 MHz. The PIC16C622A operates at 20 MHz with a 200 ns instruction cycle, which determines throughput for tight control loops. The integrated analog comparators enable direct interface to analog signals without external op-amps, saving board area. A programmable code-protection bit prevents unauthorized firmware read-back, an important security feature for commercial deployments. Typical applications include appliance control (washing machines, microwave ovens), industrial sensor interfaces, automotive body electronics (non-safety), battery chargers, and remote-control transmitters. Industrial automation subsystems such as motor speed controllers, HVAC damper actuators, and security keypads also benefit from this MCU. The industrial temperature grade supports outdoor and factory-floor deployments. Compared to PIC16F flash parts, OTP devices are lower cost in volume and well-suited to mature, fully-debugged firmware where in-field reprogramming is not required. When designing with PIC16C622A, note that OTP memory cannot be reprogrammed - firmware must be 100% validated or you will scrap parts. Use the ICSP (In-Circuit Serial Programming) interface or MPLAB PM3 device programmer for prototype bring-up. A decoupling capacitor of 0.1 uF placed close to VDD is mandatory, with additional bulk capacitance recommended near the voltage regulator. Programming voltage (VPP) of approximately 13V is required for OTP programming; verify the programming socket or ICSP header matches the Microchip reference design.

The integrated analog comparator supports up to four input channels via the AN0-AN3 pins, enabling direct interface with analog sensors without an external op-amp. The CMOS process provides low power consumption, with a typical supply current of only a few milliamps at full clock. Architecturally, the PIC16C622A uses a Harvard-style RISC core with a 14-bit instruction word and an 8-bit data path. The 35-instruction set, all single-cycle except branches, simplifies coding and timing analysis. The device supports external crystal, ceramic resonator, or RC oscillator configurations, plus a low-power LP oscillator option for battery-powered designs. The EPROM cell enables window-erasable prototype iteration when the JW package variant is used. Typical applications include appliance control, automotive body electronics, industrial sensor interfaces, low-cost remote controls, and consumer white goods where the integrated comparator simplifies analog front-end design. Compared with mask-ROM siblings, the EPROM variant is preferred for engineering samples and pre-production runs. Designers should note that the PIC16C622A is OTP (One-Time Programmable) in the plastic PDIP package and is not re-programmable in-circuit; verify firmware carefully before programming. The 40MHz speed grade requires a 10MHz input clock at the maximum 4:1 PLL-less oscillator configuration.

PIC16C622A-40/SS - 8-Bit CMOS OTP MCU, 3.5KB, 40MHz | Microchip

The Microchip Technology PIC16C622A-40/SS is an 8-bit RISC CMOS microcontroller with 3.5KB (2048 words) of One-Time Programmable (OTP) program memory, 128 bytes of RAM, and 13 general-purpose I/O pins, housed in a 20-pin SSOP package. The device operates from 2.5V to 5.5V and supports a maximum clock frequency of 40MHz, delivering 100 ns instruction execution across 35 single-word instructions. A microcontroller (MCU) is a single-chip computer containing a CPU core, non-volatile program memory, working RAM, and integrated peripherals such as comparators, timers, and I/O ports. The PIC16C622A belongs to the mid-range PICmicro family and uses a Harvard architecture with separate program and data buses, providing deterministic instruction timing that simplifies real-time control design. OTP MCUs sit in the product hierarchy as: PIC16C62x series -> mid-range PICmicro -> 8-bit PIC MCU -> microcontroller -> semiconductor. Key features of the PIC16C622A include two on-chip analog comparators with programmable reference voltage, a 16-bit timer/counter (TMR1), an 8-bit timer/counter (TMR0) with programmable prescaler, a Watchdog Timer with its own on-chip RC oscillator, and Power-on Reset / Brown-out Reset circuitry. The two comparators enable direct interface with analog signals without an external op-amp, making the part well-suited to sensor-conditioning and threshold-detection front ends. Architecturally, the PIC16C622A implements a 14-bit instruction word and a separate 8-bit data path. The OTP program memory is programmed once and cannot be erased, so this part is intended for volume production rather than prototyping (where Flash-based PIC16F equivalents are preferred). The SSOP-20 footprint also supports industrial temperature operation (-40C to +85C) under the -40 speed grade suffix used here. Typical applications include consumer appliance control, IR remote receivers, battery chargers, smoke detectors, and simple sensor interface modules. The 13 I/O pins and two comparators allow direct connection to a PIR sensor, thermistor, or photocell without external glue logic. When designing with the PIC16C622A, ensure your programmer supports the OTP variant (MPLAB PM3 or equivalent) and that the supply decoupling network uses a 100 nF ceramic capacitor placed within 5 mm of VDD. The two comparator outputs can be routed to an interrupt-on-change pin for low-power wake-up duty cycles.

It integrates 3.5 KB (2K x 14) of One-Time-Programmable (OTP) EPROM program memory, 128 bytes of RAM, and 13 digital I/O lines, making it a compact workhorse for legacy embedded control designs. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, working RAM, and peripheral I/O on one die. The PIC architecture pioneered Harvard memory separation and RISC instruction sets, with the PIC16C series introducing one-time-programmable (OTP) EPROM for code storage and an instruction set reduced to 35 single-cycle opcodes. The PIC16C622A/JW belongs to the PIC16C62X sub-family that adds a 16-bit timer/counter, an 8-bit timer, and a capture/compare/PWM (CCP) module, positioning it between basic PIC16C5X parts and the more advanced PIC16C7X series. Key features include an operating frequency up to 20 MHz, instruction-cycle time of 200 ns, an 8-bit ADC-free analog comparator, a synchronous serial port (SSP), and a programmable code protection scheme. Power consumption is typically below 2 mA at 5V/4 MHz and falls below 1 µA in sleep mode, supporting battery-aware applications. The /JW suffix indicates a windowed CERDIP package that allows UV erasure for prototype development and code iteration. Architecturally, the device uses a 14-bit instruction word with an 8-bit data path, eight-level hardware stack, and direct/indirect addressing modes. Watchdog timer with on-chip RC oscillator, power-on reset, brown-out detect, and in-circuit serial programming (ICSP) support streamline field deployment. Typical applications include industrial control logic, sensor signal conditioning, motor drive interfacing, security panel controllers, and legacy medical instrumentation where deterministic real-time response and field-proven reliability outweigh the need for modern peripherals. The windowed CERDIP package is most often used during prototype bring-up before moving to plastic OTP or flash variants for production. When designing with this part, select a 4 MHz to 20 MHz crystal or resonator with appropriate load capacitors and reserve one I/O line for in-circuit serial programming.

PIC16C622AT-04/SO

PIC16C622AT-04/SO - 8-Bit 4MHz OTP MCU 3.5KB 18-SOIC | Microchip

The Microchip Technology PIC16C622AT-04/SO is an EPROM-based 8-bit CMOS microcontroller from the PIC16C family, delivering 4 MIPS performance at 4 MHz and integrating 3.5KB (2K x 14) of one-time-programmable (OTP) program memory with 128 bytes of RAM in an 18-pin SOIC wide-body package. Its 13 digital I/O pins, 8-bit data path, and RISC architecture with 35 single-word instructions make it a classic mid-range PICmicro for cost-sensitive embedded designs. A microcontroller (MCU) is a single-chip computer that combines a CPU, memory (program + data), and peripherals on one silicon die, intended to control electronic systems through firmware. The PIC16C622A belongs to the mid-range PICmicro taxonomy (8-bit MCU -> microcontroller -> embedded controller -> semiconductor) and historically served as the workhorse of industrial, appliance, and consumer control applications before Flash-based PIC16F parts replaced most OTP variants. The PIC16C622A also integrates a dual analog comparator module (the namesake feature of the '622 family), 8-bit timer/counter, watchdog timer, and a power-saving SLEEP mode. Key features of the PIC16C622AT-04/SO include 25 mA source/sink per I/O, 4 MHz maximum oscillator frequency (4 MHz internal RC option not available on this part), 2.5V to 5.5V operating voltage, and the OTP program memory windowed on the 'A' die. Wide-voltage-range design supports both 3.3V and 5V rails, and is the reason this part continues to ship into industrial controllers and brown-good retrofit upgrade loops. The 18-SOIC (0.295-inch / 7.50mm width) package is the wide-body variant offering wider lead pitch for hand-soldering and through-hole-style process windows. Typical applications include remote transmitters, security-system peripherals, appliance controllers, automotive subsystems (non-safety), and simple sensor signal conditioning. The 13 I/O, dual analog comparator, and 4 MHz CPU throughput provide enough headroom to replace discrete logic or 4-bit controllers while keeping BOM cost low. Designers frequently migrate from PIC16C620/PIC16C621 in the same family to PIC16C622 when they need more RAM and program memory. When designing with this device, place a 0.1uF decoupling capacitor as close as possible to VDD (pin 14) and connect MCLR (pin 4) through a 10k pull-up resistor to VDD for normal operation. OTP memory can only be programmed once, so pre-production verification via PIC16C622A-04/SO (windowed) or PIC16C622A-04/JW (UV-erasable) prototypes is the standard development workflow.

The Microchip Technology PIC16C622AT-04E/SS is an EPROM-based 8-bit CMOS microcontroller from the PIC16C62X family, offering 3.5KB (2K x 14) of one-time programmable program memory, 128 bytes of RAM, and 13 digital I/O pins, all housed in a 20-pin SSOP package. Operating at up to 4 MHz across 3.0 V to 6.0 V, it integrates a RISC core, two analog comparators, a 16-bit timer/counter, and an 8-bit timer/counter for embedded control tasks. A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory, and peripherals. The 8-bit PIC16C62X family uses a Harvard RISC architecture with 35 instructions, optimized for deterministic real-time control. PIC16C622A variants fall within the wider PIC16C5X/PIC16C6X taxonomy of OTP/EPROM 8-bit microcontrollers, which belong to the broader semiconductor category of microcontrollers and embedded processors. Key features include two on-chip analog comparators with programmable reference voltage (0.6 V to (Vdd - 1.5 V)), 13 bidirectional I/O pins with individual direction control, 8-bit and 16-bit timer/counters, power-saving SLEEP mode, programmable code protection, and in-circuit serial programming (ICSP) capability. The device also offers a 25 mA source/sink capability per I/O, supporting direct LED drive in many applications. The PIC16C622AT-04E/SS is built on Microchip's low-power CMOS process and incorporates a 14-bit instruction word with 8-bit data path. With 35 single-cycle instructions (200 ns at 20 MHz, 1 µs at 4 MHz), it provides predictable execution timing suitable for interrupt-driven control. Internal oscillator options and watchdog timer improve system reliability in noisy industrial environments. Typical applications include appliance controls, security and alarm systems, automotive subsystems (post-ignition), small office equipment, sensor conditioning front-ends, and consumer electronics where compact SSOP-20 footprint, low cost, and integrated comparators simplify board design. The two analog comparators make it particularly attractive for battery monitoring, threshold detection, and zero-cross detection circuits. When designing with this MCU, ensure decoupling: place a 0.1 µF ceramic capacitor close to VDD/VSS pins. Programming the CONFIG register is mandatory before code execution. Use the ICSP interface (RB6/RB7) for in-field firmware updates, especially when migrating from the PIC16C622 to PIC16C622A silicon revision.

The Microchip Technology PIC16C622AT-20/SO is an 8-bit CMOS OTP-based microcontroller from the PIC16C family, delivering 20 MHz maximum operating frequency with 3.5 KB (2K x 14) of program memory, 128 bytes of RAM, and 13 I/O pins in a surface-mount 18-pin SOIC package. The "T" suffix denotes tape-and-reel packaging, "A" denotes the revised silicon, "20" specifies the 20 MHz speed grade, and "/SO" identifies the 18-lead SOIC (Small Outline Integrated Circuit) package, designed for cost-sensitive embedded control applications where one-time-programmable (OTP) memory is acceptable. An OTP microcontroller is a type of embedded controller that uses one-time-programmable non-volatile memory for code storage, typically chosen for low-cost, high-volume applications where firmware is finalized before production and field reprogramming is not required. Within the broader microcontroller hierarchy, OTP MCUs sit alongside flash-based MCUs as a sub-category of 8-bit microcontrollers, which themselves belong to the larger class of microcontrollers and ultimately to embedded systems and semiconductors. The PIC16C622A device supports a 2.0V to 6.0V operating voltage range, making it suitable for both 3.3V and 5V systems common in industrial and consumer electronics. Key features include a Harvard RISC architecture with 35 single-word instructions, a 14-bit instruction word, 8-level hardware stack, integrated Power-on Reset (POR), Brown-out Reset (BOR), watchdog timer with on-chip RC oscillator, and two analog comparators. The PIC16C622A also incorporates a 16-bit timer/counter (TMR1) and an 8-bit timer/counter (TMR0), enabling precise timing operations. The 13 digital I/O pins support individual direction control, and the device operates across an industrial temperature range of -40°C to +85°C. The PIC16C622A utilizes Microchip's enhanced mid-range core, providing deterministic instruction execution at 200 ns per instruction cycle at 20 MHz. The Harvard architecture separates program and data memory, allowing simultaneous fetch and access for improved throughput. The integrated analog comparators with programmable reference and configurable output polarity eliminate the need for external comparator ICs in many signal-conditioning designs. The 128-byte RAM supports general-purpose data storage, while the 3.5 KB OTP program memory is partitioned into 2K words of 14 bits each. Typical applications include appliance control (washing machines, microwave ovens, coffee makers), battery chargers, sensor signal conditioning, motor control for low-power DC fans, IR remote controls, and small consumer electronics. The device's combination of analog comparators, timers, and low power consumption makes it well-suited for stand-alone embedded systems that must operate reliably without firmware updates. When designing with this device, note that OTP memory cannot be re-programmed, so firmware must be fully validated before commitment. Engineers migrating from this OTP part to flash-based PIC16F equivalents (such as PIC16F630 or PIC16F676) can reuse code with minimal changes, while gaining in-system reprogrammability for development and field updates.

The Microchip Technology PIC16C622AT-20/SS is an 8-bit RISC microcontroller based on the PIC16C core, integrating 3.5KB (2K x 14) of One-Time Programmable (OTP) program memory, 128 bytes of RAM, and 128 bytes of EEPROM data memory in a 20-pin SSOP package. It operates at a maximum clock speed of 20MHz with a 4.0V to 5.5V supply range (commercial grade), supporting instruction cycles as fast as 200ns. A microcontroller (MCU) is a single-chip computer that integrates a CPU, RAM, non-volatile program memory, and I/O peripherals on a single die. The PIC16C series belongs to Microchip's mid-range 8-bit architecture family, sitting between baseline PIC10/12/16 devices and the enhanced PIC18 family in the broader 8-bit MCU hierarchy. OTP (One-Time Programmable) ROM variants are mask-programmed at the factory rather than field-flashed, which historically offered lower per-unit cost than flash parts but eliminated in-circuit reprogrammability, making them suitable for high-volume, fixed-functionality production. Key features of the PIC16C622AT-20/SS include two analog comparators with programmable reference, a capture/compare/PWM (CCP) module, a 5-channel 8-bit ADC, two 8-bit timers plus one 16-bit timer, an internal 4MHz RC oscillator with calibration, and a brown-out reset (BOR) circuit. The /20 speed suffix denotes a 20MHz maximum oscillator frequency, while the /SS suffix denotes a 20-lead Shrink Small Outline Package with 0.65mm pitch and gull-wing leads suitable for surface-mount assembly. The 'A' suffix indicates the silicon revision, and 'T' denotes tape-and-reel packaging. Architecturally, the device uses a 14-bit instruction word with single-cycle execution except for branch instructions, delivering ~5 MIPS sustained throughput at 20MHz. Its enhanced mid-range core includes an interrupt controller with hardware context save and a hardware multiplier for 8x8 unsigned operations. The device's low-power features include a SLEEP mode with <1µA typical standby current and wake-up on I/O change or peripheral interrupt, enabling battery-friendly designs. Typical applications include appliance control boards, sensor signal conditioning with on-chip comparator/ADC, simple motor control via the CCP module, automotive interior subsystems, security panel keypads, and consumer remote-control encoder ICs. The internal comparator and voltage reference are particularly useful for thermostat, battery monitor, and level-detection circuits. When designing with the PIC16C622AT-20/SS, note that OTP precludes firmware updates: any bug in mask-programmed firmware requires a full device replacement. For prototypes or field-upgradable designs, select the PIC16F or PIC16LF flash variants in the same pinout instead.

An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, RAM, program memory, peripherals, and I/O on one die, executing one byte (8 bits) per instruction. MCUs sit in the embedded system hierarchy above discrete logic and below SoCs/MPUs, and the PIC16C family is the classic mid-range OTP branch of Microchip's PIC portfolio. PIC16C devices use a RISC-like instruction set, Harvard memory architecture, and are ideal for cost-sensitive, small-form-factor, brown-out-tolerant embedded control where code is finalized at firmware release and not field-updatable. Key features include a 20MHz maximum clock speed, 13 digital I/O pins, an internal timer/counter, watchdog timer, power-on reset, and an operating voltage range compatible with both 3.3V and 5V rails. The 20-pin SSOP (5.30 mm body width) package is the same compact surface-mount footprint used across the PIC16C62x family, enabling PCB layout reuse when migrating between A-revision and non-A PIC16C devices. The device uses Microchip's enhanced mid-range core, which adds interrupt context saving, larger linear data memory access, and improved arithmetic semantics over the baseline mid-range. OTP program memory means the firmware is permanently written at programming time and cannot be erased, lowering unit cost versus flash equivalents for high-volume, code-final products. Typical applications include low-cost consumer appliances, white-goods control boards, simple sensor interfaces, replacement of discrete logic glue, and brown-goods remote-control units where the 3.5KB code space, 13 I/Os, and 20MHz clock cover the firmware footprint without flash overhead. When designing with this part, note that OTP memory cannot be re-programmed, so firmware must be fully validated before production programming. Because the PIC16C family is mature, confirm long-term supply with your distributor before committing to a multi-year design.

Key features include Harvard RISC instruction set with 35 single-word instructions, 200 ns instruction cycle at 20 MHz, two 8-bit timer/counters (Timer0, Timer2), one analog comparator with programmable reference, 13 digital I/O pins with individual direction control, power-on reset (POR), brown-out reset (BOR), and watchdog timer (WDT) with on-chip RC oscillator. The device supports in-circuit serial programming (ICSP) via RB6/RB7 pins despite being OTP, enabling factory pre-programming. Architecturally, the PIC16C622A uses a 14-bit instruction word with a separate data path (Harvard architecture), enabling simultaneous instruction fetch and data access. The 8-level deep hardware stack and 4 interrupt sources provide deterministic real-time response. The on-chip RC oscillator option and internal watchdog with dedicated 38 kHz RC oscillator allow reduced BOM cost in standalone designs. Typical applications include industrial control logic, appliance controllers, security alarm panels, smart sensor interfaces, automotive body electronics (non-safety), and low-end consumer products. The wide 3-5.5V operating range and industrial -40C to +85C temperature grade suit outdoor or factory-floor deployments. When designing with this part, note that OTP memory cannot be re-programmed in-circuit. Use a flash equivalent (e.g., PIC16F628A) for prototypes. The 18-pin SOIC (300 mil body) package is footprint-compatible with several PIC16F62X family parts, simplifying migration between flash and OTP variants.

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.

PIC16C622T-04I/SO

PIC16C622T-04I/SO - 8-bit MCU, 3.5KB OTP, 13 I/O | Microchip

The Microchip Technology PIC16C622T-04I/SO is an EPROM-based 8-bit CMOS microcontroller from the PIC16C family, delivering 4 MHz maximum operating frequency with 3.5 KB (2K x 14) of one-time-programmable (OTP) program memory and 128 bytes of RAM in an 18-pin SOIC (SO) package. The industrial-grade ("I") temperature variant operates from -40 °C to +85 °C and is supplied in tape-and-reel packaging (T suffix). The device exposes 13 general-purpose digital I/O pins and is rated for 3.0 V to 5.5 V operation, suiting battery-backed and 5 V regulated designs. An 8-bit microcontroller (MCU) is a single integrated device that combines a CPU core, program memory, data RAM, peripherals and I/O on one silicon die. 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.

PIC16C622T-20/SO

PIC16C622T-20/SO - 8-bit OTP MCU, 3.5KB, 20MHz, 18-SOIC | Microchip

The Microchip Technology PIC16C622T-20/SO is an 8-bit RISC microcontroller from the PIC® 16C family featuring 3.5KB (2K x 14) of One-Time Programmable (OTP) program memory, 128 bytes of RAM, and 13 digital I/O pins in an 18-pin SOIC package. 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. This page synthesizes verified distributor pricing, drop-in alternatives within the same 18-SOIC footprint, and practical design notes not consolidated in the manufacturer datasheet.

PIC16C622T-20E/SO

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

The Microchip Technology PIC16C622T-20E/SO is an 8-bit PIC 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 surface-mount 18-SOIC (7.50 mm / 0.295 inch width) package. The device integrates 13 digital I/O pins, two analog comparators with a programmable reference, an internal 8-bit timer/counter, a watchdog timer, and brown-out reset, providing a compact mixed-signal control solution. A microcontroller (MCU) is a single-chip computer containing a CPU core, program memory, working RAM, and peripheral set on one die. OTP MCUs use one-time programmable EPROM cells so firmware is permanently committed during production programming; unlike flash parts, the program memory cannot be rewritten, which historically made OTP devices attractive for cost-sensitive high-volume consumer and industrial control. The PIC16C family sits in the 8-bit RISC hierarchy of Microchip's portfolio, with Harvard architecture, 14-bit-wide instructions, and a small instruction set optimized for deterministic interrupt response and low code size. Key features of the PIC16C622T-20E/SO include 20 MHz maximum clock, 200 ns instruction cycle, 128 bytes RAM, two on-chip analog comparators, a programmable voltage reference, an internal RC oscillator option, power-on reset, brown-out reset, watchdog timer with on-chip low-power oscillator, in-circuit serial programming (ICSP), and a wide 3.0 V to 6.0 V supply range. The 18-SOIC industrial-grade (-40 °C to +125 °C) package makes it suitable for harsh environment installations. 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.
