PIC16C622-20E/P - 8-Bit 20MHz OTP MCU 3.5KB | Microchip

The Microchip Technology PIC16C622-20E/P is a 20 MHz 8-bit CMOS PIC microcontroller in an 18-pin PDIP through-hole package, featuring 3.5 KB of One-Time Programmable (OTP) program memory organized as 2K x 14, 128 bytes of RAM, and 13 general-purpose digital I/O pins. It operates across an extended industrial temperature range, indicated by the "E" designator, and supports 3 V to 5.5 V supply operation. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (ROM/OTP/Flash), working RAM, and peripheral interfaces (GPIO, timers, ADC, communication) into one device. The PIC16C family sits in the hierarchy: microcontroller -> embedded MCU -> 8-bit RISC MCU -> semiconductor IC. OTP-based PIC16C parts are programmed once at production and retain code permanently, making them suitable for high-volume, cost-sensitive, fixed-function products where firmware will not change in the field. Key differentiating features of the PIC16C622-20E/P include its 20 MHz maximum clock (200 ns instruction cycle), 14-bit instruction word with single-cycle ALU operations, a hardware analog comparator module, and 13 GPIO pins arranged across ports A and B. The device offers low-power CMOS operation with sleep/idle modes, internal brown-out reset, watchdog timer, and power-on reset support. Architecturally, the PIC16C622-20E/P uses Microchip's enhanced mid-range 8-bit RISC core with a hardware multiplier absent, a 14-bit program counter, and a Harvard-style separate program and data bus. Its peripherals include one 8-bit timer (TMR0) and one 16-bit timer (TMR1) with capture/compare, plus the analog comparator block for sensor interfacing. Typical applications include automotive body controllers, appliance control boards, simple sensor interfaces, battery chargers, and industrial control modules. The 18-pin PDIP package with through-hole leads suits hand-soldered prototypes, educational platforms, and through-hole production runs. A key design consideration is that the OTP memory is one-time programmable and cannot be erased, so production programming requires a validated firmware image. Engineers should plan for a Flash-based PIC16F equivalent for field updates and prototypes, while reserving the PIC16C622-20E/P for fixed-code, high-volume production. This page synthesizes real-time distributor pricing, drop-in same-package alternatives, and practical design notes that go beyond the manufacturer datasheet to help engineers and buyers evaluate the PIC16C622-20E/P for new designs and EOL replacements.

The 20MHz maximum clock rate supports time-critical control loops, while OTP program memory enables fast prototyping before committing to a masked ROM variant. Architecturally, the PIC16C622 uses CMOS EPROM technology with a 14-bit instruction word. Its 35 single-word instructions, 8-level hardware stack, and direct/indirect data addressing simplify assembly-language programming. The integrated brown-out design with secondary oscillator and dual analog comparators make it well suited for mixed-signal embedded designs. Typical applications include automotive body controllers, white-goods appliance control, security and fire-alarm sensor interfaces, simple motor control loops, and industrial instrumentation front-ends. The extended (E) temperature grade qualifies it for underhood and dashboard automotive environments. When designing with this OTP part, plan firmware before programming because OTP parts cannot be reprogrammed in-circuit. Ensure the decoupling network (100nF plus 10uF bulk) sits within 5mm of VDD/VSS pins, and reserve MCLR with the proper external pull-up configuration.

The Microchip Technology PIC16C622-20I/P is an 8-bit CMOS EPROM/ROM-based 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 a through-hole 18-pin PDIP package. It executes instructions at up to 20 MHz from a 2.5V to 6.0V supply and is rated for the industrial temperature range of -40°C to +85°C. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory, working RAM, and peripheral I/O on one die. The PIC16C622 belongs to the mid-range PIC architecture family (microcontroller -> 8-bit MCU -> PIC16 family -> Microchip mid-range) and uses a RISC instruction set optimized for deterministic single-cycle execution. The PIC16C622 specifically adds an internal comparator peripheral alongside the standard PIC16C62x core, making it a frequent choice for analog-front-end embedded designs without external op-amps. Key features of the PIC16C622-20I/P include 4 MHz operation at <2 mA typical and a deep sleep mode drawing under 1 µA at 3V/32 kHz, a 15-bit instruction word, hardware USART, two 8-bit timers plus one 16-bit timer, a programmable watchdog timer with on-chip RC oscillator, and in-circuit serial programming (ICSP) capability. The OTP EPROM program memory is windowless, allowing one-time field programming through standard Microchip device programmers. Architecturally, the PIC16C622 uses a Harvard bus with separate program and data paths, a 14-bit wide instruction word, and a hardware stack eight levels deep.

PIC16C622-20I/SS - 8-bit EPROM MCU, 3.5KB, 13 I/O | Microchip

The Microchip Technology PIC16C622-20I/SS is an EPROM-based 8-bit CMOS microcontroller with 3.5KB (2K x 14) of program memory, 128 bytes of RAM, and 13 digital I/O pins, housed in a 20-pin SSOP package. It operates at up to 20 MHz from a 2.5V to 6.0V supply, supports external oscillator mode, and is qualified for the industrial -40C to +85C temperature range. A microcontroller (MCU) is a single-chip computer containing a CPU, non-volatile program memory, volatile data memory, and programmable peripherals. PIC microcontrollers use a RISC (Reduced Instruction Set Computer) Harvard architecture that separates program and data buses, allowing simultaneous instruction fetch and data read for higher throughput than von-Neumann designs at the same clock rate. PIC16C-series parts are one-time-programmable (OTP) EPROM variants targeted at cost-sensitive volume production where code stability has been finalized. Key features include 13 bidirectional I/O pins with individual direction control, a 20 MHz internal execution rate (200 ns instruction cycle), one 8-bit timer/counter and one 16-bit timer/counter, an analog comparator, and an internal/ external oscillator option. The device draws approximately 2 mA at 5V/4 MHz and less than 1 uA in standby, making it well suited to battery-powered instrumentation. Watchdog timer and power-on reset are integrated for unattended embedded deployments. The PIC16C622-20I/SS uses Microchip's mid-range 14-bit instruction set shared across the PIC16F/C/CR family, with 35 single-word instructions. Development is supported by MPLAB X IDE, MPLAB XC8 compiler, and the PICkit 3/4 programmers, allowing code migration to flash-based PIC16F variants when production volumes justify the conversion from OTP EPROM. The SSOP-20 footprint is shared with PIC16C620A, PIC16C621A, and PIC16F628 families, enabling PCB reuse across device grades. Typical applications include low-cost industrial controls, appliance control boards, sensor signal conditioning, simple PWM motor drivers, and battery-powered handheld instruments where SSOP-20 footprint, EPROM one-time programmability, and proven PIC16 mid-range toolchain support are decisive selection criteria. When designing with this device, plan code migration paths early: OTP EPROM cannot be re-programmed, so any firmware bug becomes a scrapped PCB. Also budget a 100 nF decoupling capacitor adjacent to VDD with a wide ground return, and respect the 6.0V absolute maximum to avoid latch-up in industrial bus-powered designs.

PIC16C622/JW

PIC16C622/JW - 8-Bit 20MHz CMOS MCU, 3.5KB EPROM, 18-CERDIP

The Microchip Technology PIC16C622/JW is an 8-bit CMOS RISC microcontroller from the PIC16C family, featuring a 20MHz maximum clock speed, 3.5KB (2K x 14) of One-Time-Programmable (OTP) EPROM program memory, and 128 bytes of data RAM, all housed in an 18-pin windowed CERDIP package for UV-erasable development. Headline parameters include 13 digital I/O lines, a Harvard RISC architecture with 35 single-cycle instructions, and an external oscillator interface supporting crystal, resonator, or external clock sources across a 3.0V to 6.0V supply range. A PIC16C-series microcontroller is a member of the Microchip 8-bit PIC RISC family, characterized by a separate program and data bus (Harvard architecture) that allows simultaneous instruction fetch and data access. The PIC16C line is the original CMOS-EPROM cousin of the flash-based PIC16F line, designed for legacy, low-volume, and one-time-programmable applications where UV erasure for reuse or field reprogramming is desired. Within the broader hierarchy, PIC16C sits under PICmicro -> 8-bit microcontroller -> microcontroller -> embedded computing -> semiconductor. The /JW suffix specifically denotes the ceramic windowed package for prototype development. Key features include 14-bit instruction word width, an internal watchdog timer with on-chip RC oscillator, power-saving SLEEP mode, in-circuit serial programming (ICSP) capability, and a programmable code-protection scheme. The device provides two 8-bit timers (Timer0 and Timer2-equivalent), one capture/compare/PWM module, and a 5-channel 8-bit ADC on selected variants. The 18-CERDIP windowed package allows UV erasure of the EPROM for code iteration during development, a feature lacking in standard OTP-only /JW-less variants. The PIC16C622's RISC architecture delivers near 5 MIPS performance at 20MHz, with most instructions executing in a single 200ns instruction cycle. Internal features include a 4MHz internal RC oscillator option (on selected variants), a brown-out reset circuit, and interrupt capability with hardware context saving. The wide 3.0V to 6.0V operating voltage range makes it suitable for both 3.3V and 5V system designs without level translation. Typical applications include industrial control systems, automotive body electronics, consumer appliance controllers, and legacy replacement for older PIC16C5x designs requiring more I/O and peripheral features. The windowed CERDIP package makes the /JW variant specifically suited for engineering development and code validation rather than high-volume production. When designing with the PIC16C622/JW, note that the ceramic windowed CERDIP package is significantly more expensive than plastic OTP or flash equivalents and is intended for development. Production runs should migrate to the PIC16C622-20/P or PIC16F622-20/P flash-based pin-compatible variants after code is finalized. The part requires a 13V nominal Vpp supply for EPROM programming and an external programming clock.

PIC16C622A-04/P

PIC16C622A-04/P - 8-Bit 4MHz OTP MCU, 3.5KB | Microchip

The Microchip PIC16C622A-04/P is a member of the PIC16C6xx mid-range family of 8-bit CMOS microcontrollers housed in a through-hole 18-pin PDIP package. It integrates a 3.5KB (2K x 14-bit) One-Time-Programmable (OTP) program memory, 128 bytes of RAM, and 13 general-purpose I/O pins, all driven by a 4MHz internal oscillator-compatible clock. The device executes 35 single-word instructions with a 200 ns instruction cycle (1 µs per two-cycle branch), giving it deterministic throughput for embedded control. An MCU (Microcontroller Unit) is a single-chip computer that integrates a CPU core, program memory, data memory, and peripheral I/O on one die, enabling compact embedded designs. Within the taxonomy, the PIC16C622A belongs to the 8-bit microcontroller hypernym, which descends from microcontroller -> microprocessor -> integrated circuit -> semiconductor. As an OTP-EPROM-based part, it is field-programmable exactly once, in contrast to Flash-based PIC16F variants which are re-programmable, making it well suited to fixed-cost high-volume consumer and industrial control. Key features include a 2K x 14 program word OTP, 128 bytes of data RAM, two 8-bit timers (Timer0, Timer2) and one 16-bit Timer1 with capture/compare capability, a 10-bit resolution analog comparator module with two comparators, an internal voltage reference, a programmable Watchdog Timer with its own on-chip RC oscillator, and 13 I/O pins with individual direction control. The interrupt architecture supports 10 sources through a single interrupt vector with context saving, and the device supports in-circuit serial programming (ICSP). Architecturally, the PIC16C622A uses a 14-bit wide instruction word and a Harvard architecture with separate program and data buses. The OTP cell is programmed by injecting hot electrons onto a floating gate, then read back through a sense amplifier. Compared with mask-ROM PIC16C62x devices, the OTP version allows prototype and low-volume production without the NRE mask charge, and Microchip offers a windowed UV-erasable JW package for development. Typical applications include appliance control, lighting ballasts, sensor signal conditioning with on-chip comparators, automotive body electronics subsystems, and any low-cost fixed-function 8-bit control node. The wide 3.0 V to 6.0 V operating range permits both 3.3 V and 5 V designs. Engineers migrating from the PIC16C62x mask-ROM family to an OTP-based device with identical pinout will find this a drop-in option. The available -04 speed grade (4 MHz) and -20 speed grade (20 MHz) cover most embedded control tasks. The device is supported by the Microchip MPLAB development environment, including MPASM assembler, MPLAB-SIM simulator, and PICSTART Plus / MPLAB PM3 device programmers. One key design consideration: because this is a OTP-EPROM part, firmware is committed permanently after the first programming cycle; any firmware revision requires a new device and a redesigned PCB programming flow. For development cycles requiring repeated reprogramming, the equivalent PIC16F62x Flash family is recommended. Additionally, ESD precautions must be observed during OTP programming to avoid cell damage.

It is housed in a 20-pin SSOP (Shrink Small Outline Package) and operates from a 3.0 V to 6.0 V supply range, supporting both 3.3 V and 5 V designs. An 8-bit microcontroller is a single-chip computer that integrates a CPU, memory (program and data), and peripherals onto one die, executing one byte at a time. The PIC16C62x family sits in the hierarchy: 8-bit MCU -> microcontroller -> embedded processor -> semiconductor. RISC (Reduced Instruction Set Computer) designs such as the PIC16C use a small, fixed-width instruction set to achieve deterministic instruction timing (typically 100 ns per instruction at 20 MHz, 250 ns at 4 MHz) which simplifies real-time embedded control. Key features of the PIC16C622A-04/SS include an integrated analog comparator with programmable on-chip voltage reference, a 16-bit timer/counter (TMR1) with internal 200 ns resolution, a Watchdog Timer with its own on-chip RC oscillator for reliable resets, code protection to prevent unauthorized memory reads, and an OTP memory windowed package option for prototype programming. The A variant adds Microchip's enhanced feature set over the original PIC16C622. Technically, the device employs a Harvard architecture with separate program and data buses, allowing instruction fetch and data access to occur simultaneously. The 14-bit wide instruction word and 8-bit data path balance code density against computational simplicity. Power consumption is typically below 2 mA active at 5 V/4 MHz, with a sleep mode drawing microampere-level standby current. Typical applications include consumer appliance control, security and access systems, automotive body electronics, low-cost sensor interfaces, IR remote control receivers, and small form-factor industrial controllers. Its compact 20-pin SSOP package suits space-constrained designs. When designing with this part, choose the right oscillator configuration (RC, XT, HS) early, ensure MCLR reset hardware is correct, and reserve the comparator pins if not used as analog inputs. OTP means firmware must be fully validated before programming, as the device cannot be erased.

PIC16C622A-04E/P

PIC16C622A-04E/P - 4MHz 8-Bit CMOS MCU, 3.5KB OTP | Microchip

The Microchip Technology PIC16C622A-04E/P is an EPROM-based 8-bit CMOS microcontroller in the PIC16C family, delivering 4 MIPS performance at 4 MHz from a 2.5 V to 6.0 V supply in an 18-pin PDIP through-hole package. It integrates 3.5 KB (2 K x 14) of One-Time-Programmable (OTP) program memory, 128 bytes of RAM, 13 digital I/O pins, and a 13-bit instruction word with an 8-bit data path. The "-04E" suffix denotes a 4 MHz maximum clock speed and the "E" extended temperature grade (-40 °C to +125 °C), while the "/P" suffix identifies the PDIP-18 package. A microcontroller (MCU) is a single-chip computer that contains a CPU core, program and data memory, peripherals, and I/O on a single die. MCUs are the smallest members of the embedded computing hierarchy (microcontroller -> microprocessor -> SoC -> computer) and are used wherever deterministic, low-cost, low-power control is needed. The PIC16C family uses a RISC Harvard architecture with a 14-bit instruction word optimized for compact code density, an approach Microchip introduced in the 1970s and that remains popular in cost-sensitive 8-bit designs. Key features include a fully static design for low-power operation, wide 2.5 V-6.0 V supply range, internal watchdog timer, power-on reset, brown-out reset, and two analog comparators with programmable reference. Power consumption is typically 15 µA at 5 V/4 MHz and as low as 1 µA at 3 V/32 kHz, making this part well-suited to battery-backed industrial controllers. The architecture pairs a 13-bit program counter with hardware multiply support and a 14-bit-wide EPROM/ROM store, giving the device a code-density advantage over 8-bit-worded CISC alternatives. The two on-chip analog comparators can be configured as a single differential amplifier, a window comparator, or as general-purpose logic gates via the TRIS registers, reducing the need for external analog components. Typical applications include appliance control (washing machines, microwave ovens), industrial sensor interfaces, automotive body electronics (pre-CAN nodes), battery chargers, and remote controls. Designers choose the PIC16C622A when they need more on-chip analog capability than the PIC16C620/621 provide while staying within the 18-pin PDIP footprint. When designing with the PIC16C622A-04E/P, remember that the OTP memory is one-time-programmable only - firmware cannot be field-updated.

PIC16C622A-04I/P

PIC16C622A-04I/P - 8-bit 4MHz OTP MCU 3.5KB | Microchip

The Microchip Technology PIC16C622A-04I/P is an EPROM-based 8-bit CMOS microcontroller with 4 MHz maximum clock input, 3.5 KB (2K x 14) OTP program memory, and 128 bytes of RAM, housed in a 18-pin PDIP through-hole package. It integrates 13 I/O pins, one 8-bit timer/counter, and a capture/compare/PWM (CCP) module plus a USART, making it well suited to legacy embedded control applications. The '-04' speed suffix denotes a 4 MHz oscillator maximum, while the 'I' temperature grade specifies an industrial -40C to +85C operating range. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory (ROM/EPROM/Flash), data memory (RAM), and peripheral I/O on one die. The PIC16C62x family belongs to Microchip's mid-range PIC16 architecture, sitting hierarchically between baseline PIC10/12/14 devices and enhanced PIC17/18 families. Compared with 32-bit Cortex-M cores, 8-bit MCUs trade raw performance for deterministic interrupt latency, low power, smaller code footprint, and BOM cost. Key features of the PIC16C622A include 35 single-word instructions (200 ns instruction cycle, two-cycle branches), an 8-level deep hardware stack, in-circuit serial programming (ICSP) capability, a watchdog timer with on-chip RC oscillator, power-on reset, brown-out reset, and an internal/external interrupt source. The 13 I/O pins can source/sink 25 mA each, sufficient to drive LEDs, small relays, and optocouplers directly. Technically, the device uses a RISC Harvard architecture with separate program and data buses to allow instruction fetch and operand read in one cycle. The 14-bit instruction word enables direct, immediate, and relative addressing. Two 8-bit timer/counters (TMR0, TMR2) plus one 16-bit timer/counter (TMR1) are available on some family variants; on the PIC16C622A itself TMR0 is the primary counter. Typical applications include industrial control panels, automotive body electronics (non-safety), appliance controls, security sensor interfaces, and remote keyless entry receivers. Its OTP program memory makes it best suited for production designs where firmware is stable and not field-upgradable. When designing with this part, note that OTP memory cannot be reprogrammed - engineering samples use the windowed JW package, and firmware changes after volume commitment require a new mask. For new designs, the flash-based PIC16F628A is usually recommended as the modern equivalent.

The PIC16C622A also provides a 4 MHz internal-execution rate from an external 4 MHz crystal, an 8-bit parallel slave port, and up to 13 bidirectional I/O pins with high-current sink/source capability. Architecturally, the device uses a 14-bit wide program word with separate program and data buses (Harvard architecture), enabling simultaneous instruction fetch and data access. The 4 MHz oscillator combined with a 4:1 instruction-pipeline divider delivers a 1 µs single-cycle instruction time (200 ns cycle at 20 MHz), while the on-chip Power-on Reset, Brown-out Reset, and Watchdog Timer provide robust field-deployment reliability. Typical applications include consumer appliance control, security system panels, automotive body modules, industrial sensor interfaces, low-cost remote controls, and small-form-factor motor-driver front-ends. The wide operating voltage and industrial temperature range also suit battery-powered instrumentation and HVAC peripheral controllers. When designing with this part, note that OTP memory cannot be re-programmed in-circuit; for development or low-volume production, choose a Flash-based equivalent such as PIC16F627A or PIC16F628A in the same 18-pin SOIC footprint to reuse PCB layout and firmware libraries.

PIC16C622A-04I/SS

PIC16C622A-04I/SS - 8-Bit OTP MCU, 4MHz, 3.5KB | Microchip

The Microchip PIC16C622A-04I/SS is a CMOS OTP-based 8-bit microcontroller from the PIC16C family, executing instructions in 200 ns at 4 MHz and packaged in a 20-pin SSOP (0.209 inch / 5.30 mm body width). It integrates 3.5 KB of one-time-programmable program memory (2K x 14), 128 bytes of RAM, 13 digital I/O lines, two analog comparators, an 8-bit timer/counter (TMR0), and a watchdog timer with its own on-chip RC oscillator. An 8-bit microcontroller is a single-chip computer that processes data 8 bits at a time and integrates CPU, memory, and peripherals on one die. PIC microcontrollers use a RISC (Reduced Instruction Set Computer) architecture with a small, fixed instruction set (35 single-word instructions for the PIC16C6xx family), which simplifies decoding and lets the device execute most instructions in a single instruction cycle. The PIC16C622A belongs to the mid-range PIC family - positioned between base-line PIC10/12/16 devices and the PIC17/PIC18 high-end family - and is widely used in cost-sensitive embedded control where ROMless or OTP flexibility is acceptable. Key features include a wide 3.0 V to 6.0 V operating range, low-power CMOS design, programmable code protection, an in-circuit serial programming (ICSP) interface via RB6/RB7, and two on-chip comparators that can be used as a voltage reference or for analog signal conditioning. The '04' speed grade marks 4 MHz operation; the 'I' suffix denotes the industrial temperature grade (-40 C to +85 C); the '/SS' suffix denotes the 20-pin SSOP package. Typical applications include appliance control, sensor interfaces, consumer electronics, battery chargers, simple motor control loops, and low-cost replacement of discrete logic. The internal comparators make the part especially attractive for power-supply monitoring, battery-level detection, and threshold-detection circuits. The 13 I/O pins can directly drive LEDs, keypads, or low-side transistors. Designers should pay attention to OTP programming - once programmed, the part cannot be electrically erased, so development is normally done with a windowed (JW) or flash equivalent (PIC16F622) before committing to the OTP version. The SSOP package requires standard surface-mount reflow; pad design follows JEDEC MS-150 guidelines. Brown-out detection is internal but not user-configurable, and the device has no on-chip hardware UART (asynchronous serial) - any serial bit-banging must be done in firmware on the I/O pins.

The Microchip Technology PIC16C622A-20/SO is an EPROM/OTP-based 8-bit CMOS microcontroller from the PICmicro mid-range family, executing one instruction in 200ns at the 20MHz maximum clock rate. It integrates 3.5KB (2K x 14) of one-time-programmable program memory, 128 bytes of RAM, and 13 digital I/O pins in an 18-pin wide-body SOIC package. The device operates from a single 2.5V to 5.5V supply, making it equally suited to 3.3V and 5V logic designs, and is specified over the commercial 0C to +70C temperature range. What is a PIC16C62X microcontroller? It is a member of Microchip's mid-range PIC family built on a RISC (Reduced Instruction Set Computer) Harvard architecture that uses separate program and data buses. The PIC16C62X series pairs a 14-bit wide instruction word with an 8-bit data path, providing higher code density than the entry-level 12-bit PIC cores while keeping the instruction set small (only 35 single-word instructions to learn). Positioned in the hierarchy as microcontroller -> embedded MCU -> 8-bit MCU -> PIC micro -> semiconductor, the PIC16C62X family is widely used in appliance controls, security panels, automotive body electronics, IR remote controls, and low-cost consumer products. Key features of the PIC16C622A include two on-chip analog comparators (the defining trait that distinguishes the 'C62X family from generic PIC16C55x/56x/57x parts), a watchdog timer with on-chip RC oscillator, power-on reset, brown-out reset, an internal 4MHz RC oscillator option to reduce external component count, and a programmable code-protection scheme. The OTP EPROM is written with an external device programmer such as the Microchip MPLAB PM3, and the part supports in-circuit serial programming (ICSP) on most I/O pins via dedicated programming lines. Typical applications include security alarm panels, appliance controllers, sensor signal conditioning, IR remote receivers, automotive interior lighting and accessory modules (non-safety), and small motor-driver interfaces. The integrated comparators allow direct analog-sensor interface (light, temperature, current) without a separate op-amp, lowering BOM cost in volume production. When designing with the PIC16C622A-20/SO, note that the OTP variant cannot be reprogrammed in-circuit; for development, use the JW windowed or QFP UV-erasable package. Place a 0.1uF decoupling capacitor as close to the VDD/VSS pins as possible and follow Microchip's recommended PCB layout for the chosen oscillator to avoid start-up problems and erratic resets.

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-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.

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.

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.

It operates from a 2.5V to 5.5V supply (3.3V/5V nominal), integrates a precision analog comparator, and is built on a fully-static RISC architecture with only 35 single-word instructions to learn. The PIC16C622A is part of the PIC16C62X family of 18 and 20-pin ROM/EPROM-based microcontrollers. An EPROM-based MCU (Erasable Programmable Read-Only Memory microcontroller) is a member of the broader 8-bit microcontroller category and sits inside the larger hierarchy of microcontrollers -> embedded microcontrollers -> microprocessors -> semiconductors. EPROM-based parts are one-time or window-erasable and are typically used for prototype development and low-volume production where Flash-based devices are not yet validated. Key features include 13 I/O pins with individual direction control, one 8-bit timer (TMR0) with an 8-bit prescaler, a Watchdog Timer with its own on-chip RC oscillator for reliable recovery, Power-on Reset, Power-up Timer, and Oscillator Start-up Timer. 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. This page synthesizes distributor stock and pricing, drop-in EPROM/Flash equivalents in the same PDIP-18 footprint, and practical design notes not found in the manufacturer datasheet alone.

PIC16C622A-40/SS

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. This page synthesizes distributor pricing, parametric alternatives, and pin-compatible OTP substitutes not consolidated on any single manufacturer page, including a direct side-by-side with the Flash-based PIC16F equivalents that simplify prototyping.

PIC16C622A/JW

PIC16C622A/JW - 8-bit 20MHz 3.5KB EPROM MCU | Microchip

The Microchip Technology PIC16C622A/JW is an 8-bit CMOS RISC microcontroller from the PIC® 16C family, delivering 20 MHz core performance with 200 ns single-cycle instruction execution in an 18-pin CERDIP windowed package. 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. Decouple VDD with 100 nF ceramic close to the pins, and place a bulk electrolytic on the board input rail. This page synthesizes distributor pricing, drop-in alternatives within the same 18-pin CERDIP footprint, and practical design notes that go beyond the manufacturer datasheet.

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

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.
