PIC16C57C-40/SO

PIC16C57C-40/SO - 8-bit OTP MCU, 3KB EPROM, 28-SOIC | Microchip

The Microchip Technology PIC16C57C-40/SO is a CMOS OTP-based 8-bit RISC microcontroller delivering 100 ns instruction execution in a 28-pin SOIC wide-body package. It integrates 3KB of one-time-programmable EPROM program memory, 72 bytes of RAM, and 20 digital I/O lines, executing code from a 12-bit-wide instruction set of 33 single-word instructions. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory, working RAM, and peripherals on one die. The PIC16C57C belongs to the PIC16C5X baseline family, sitting in the broader hierarchy of microcontroller -> embedded processor -> digital IC -> semiconductor. This category is designed for deterministic, low-cost, low-power control tasks where an entire system can be implemented with one chip plus passives. Key features include a 40 MHz maximum oscillator input (giving 100 ns instruction cycle), 2K x 12-bit program word organization, 8-bit timer/counter with 8-bit prescaler, watchdog timer with dedicated on-chip RC oscillator, power-on reset, and a wide 2.5V to 6.0V operating range. The C-grade device is specified for the commercial 0C to +70C temperature range. A 12-bit instruction word yields roughly 2:1 code compression over competing 8-bit MCUs, which lowers ROM usage in code-dense applications. Architecturally, the PIC16C57C uses a Harvard-style separate program/data bus, single accumulator W register, and two-level hardware stack. Its CMOS OTP process delivers low operating current (typically <2 mA at 5V/4 MHz, <30 uA standby) and the device is also available in windowed ceramic EPROM and QTP/SQTP programming options for prototyping. Unlike modern Flash PIC16F parts, the 'C' suffix denotes OTP, so code is locked at production programming. Typical applications include appliance controllers, automotive subsystems (non-safety), industrial control logic, low-end user-interface boards, and remote sensor transmitters. The 20 I/O pins and 33-instruction RISC core make it well suited to replace discrete logic and small gate arrays. When designing with the PIC16C57C-40/SO, note that OTP devices cannot be reprogrammed in-circuit; allocate engineering time to verify firmware on a windowed or flash equivalent before committing to OTP. Always place a 0.1 uF decoupling capacitor within 5 mm of VDD, and keep the OSC1/OSC2 trace lengths matched when using a crystal.

PIC16C57C-40/SP

PIC16C57C-40/SP - 8-bit OTP MCU 2KB EPROM 20MHz DIP-28 | Microchip

The Microchip Technology PIC16C57C-40/SP is a CMOS OTP-based 8-bit RISC microcontroller in a 28-pin SPDIP (Skinny Plastic DIP) through-hole package, executing instructions in 100 ns at a 40 MHz oscillator input. It packs 2 KB of one-time-programmable EPROM program memory, 72 bytes of RAM, and 20 digital I/O pins, making it a compact workhorse for legacy embedded designs. The part operates from a 3.0 V to 5.5 V supply and features 33 single-word instructions, brown-out detection, a watchdog timer, and a power-on reset circuit. A PIC microcontroller is a Harvard-architecture 8-bit MCU family from Microchip that pairs a separate program and data bus with a streamlined RISC instruction set, allowing deterministic single-cycle execution of most opcodes. The PIC16C5x sits at the entry tier of this family with OTP EPROM rather than flash, which means firmware is committed at programming time and cannot be erased electrically - an advantage for security-sensitive or low-cost production where re-programmability is not required. This part category is positioned under 8-bit microcontrollers within the broader microcontroller IC hierarchy. Key features of the PIC16C57C-40/SP include 2K x 12-bit word program memory (2 KB EPROM), 72 x 8 RAM, 20 I/O, a 3.0-5.5 V operating range, 12-bit wide instructions, an 8-bit timer/counter with prescaler, and power-saving SLEEP mode. The 'C' suffix denotes the CMOS low-power revision with improved brown-out and watchdog specifications versus earlier PIC16C5x die. Typical applications include industrial control replacement boards, automotive body controllers, appliance controls, simple sensor interfaces, and remote sensor transmitters where the OTP memory and DIP-28 form factor remain desired. The 40 MHz rating supports a 100 ns instruction cycle, enabling timing-sensitive loops without wait states. When designing, remember that OTP parts require verified firmware before programming because there is no in-circuit erase path - and DIP-28 footprint remains compatible with legacy hand-soldered and socketed boards long after flash-based successors were introduced.

PIC16C57C/JW - 8-bit 20MHz EPROM MCU, 3KB, 28-CDIP Window | Microchip
PIC16C57C/JW

PIC16C57C/JW - 8-bit 20MHz EPROM MCU, 3KB, 28-CDIP Window | Microchip

The Microchip Technology PIC16C57C/JW is a CMOS OTP-based 8-bit microcontroller from the PIC® 16C family, packaged in a 28-pin Ceramic DIP (CDIP) with an erasable UV window, operating at up to 20 MHz instruction rate. According to the Microchip product page, it integrates 3 KB of program memory (2K × 12 EPROM), 72 bytes of RAM, and 20 digital I/O pins, executing each instruction in 100 ns using only 33 single-word instructions. An 8-bit microcontroller (MCU) is a single-chip computer that combines a CPU, RAM, non-volatile program memory, and peripheral I/O on one die. The PIC® 16C family sits within Microchip's mid-range PIC architecture hierarchy: PIC® 8-bit MCU -> microcontroller -> embedded processor -> semiconductor. These MCUs are widely used as state machines, glue logic, and simple control cores where deterministic instruction timing and minimal external parts matter more than raw throughput. The PIC16C57C delivers an instruction cycle of 200 ns (one fetch, one execute) from a 20 MHz oscillator, supports a 2-level hardware stack, and offers programmable I/O ports (PORTA/B/C) with individual direction control. Watchdog timer with on-chip RC oscillator and Power-on Reset reduce external component count. A power-saving SLEEP mode and selectable oscillator options (RC, XT, LP, HS) provide flexibility across 2.0 V to 6.0 V operation. The architecture is a RISC-style Harvard design with separate 12-bit program and 8-bit data paths. Code is stored in UV-erasable EPROM (the /JW windowed package allows re-programming after erasing with ultraviolet light, distinguishing it from one-time-programmable /P and /SP plastic DIP variants). CMOS process technology keeps supply current low even at full clock speed, making it suitable for battery and industrial applications. Typical applications include automotive body electronics, industrial control logic, remote sensor interfaces, and legacy embedded systems. Engineers migrating older PIC16C5x designs often retain the PIC16C57C/JW in production because the JW windowed package allows iterative firmware development with UV erase, unlike OTP variants. When designing with this device, note that the 28-CDIP (JW) windowed package is intended for prototyping and engineering samples; for production runs, consider the /P (plastic DIP) or /SP (skinny plastic DIP) OTP variants. The UV window requires a quartz window cover, and erasure requires approximately 20 minutes of UV exposure at the recommended intensity.

PIC16C57CT-04/SS

PIC16C57CT-04/SS - 8-bit PIC MCU, 4MHz, 3KB OTP, 28-SSOP

The Microchip Technology PIC16C57CT-04/SS is an 8-bit CMOS OTP-based PIC16C microcontroller running at 4MHz instruction frequency, packaged in a 28-pin SSOP (0.209", 5.30mm width) surface-mount form factor. The device integrates 3KB (2K x 12) of one-time-programmable program memory, 72 bytes of data RAM, and 20 digital I/O pins, operating from a 3V to 5.5V supply. The "CT" tape-and-reel suffix and "04" speed grade indicate the 4MHz commercial-temperature variant supplied on reel. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory, data RAM, and peripheral I/O on one die, intended for embedded control tasks. Within the semiconductor hierarchy, MCUs belong to the broader family of microcontrollers and embedded processors, sitting below microprocessors in complexity but above simple logic ICs in capability. The PIC16C5X family in particular uses a 12-bit-wide instruction set with a RISC architecture, delivering 2:1 code compression versus competing 8-bit MCUs in the same price class. The "C" suffix indicates CMOS technology with OTP program memory. Key features of the PIC16C57CT-04/SS include a Harvard RISC CPU with 33 single-word instructions, Power-on Reset (POR), a Watchdog Timer (WDT) for reliable operation in noisy environments, and an external oscillator interface supporting RC, XT, LP, and HS modes. The 20 I/O pins can source/sink digital signals for buttons, relays, displays, and discrete logic interfaces. The 4MHz maximum instruction rate yields a 250ns instruction cycle, sufficient for slow-loop control and human-interface timing. Architecturally, the device uses a Harvard memory layout with separate program and data buses, eliminating the need for an instruction prefetch queue. The 12-bit instruction word reduces code density overhead, while the two-stage pipeline overlaps fetch and execute for consistent throughput. Internal peripherals are kept simple: two timers, a watchdog, and an 8-bit prescaler shared with Timer0. Typical applications include industrial control subsystems, consumer appliances, low-cost automotive body electronics, hobbyist projects, and replacement of discrete logic with programmable control. With 20 I/O, 72 bytes RAM, and 3KB OTP, the device fits applications where deterministic bit-level I/O handling matters more than arithmetic throughput, such as keypad scanners, LED multiplexers, and simple sensor conditioning. A key design consideration: because PIC16C57C is OTP (one-time programmable), field firmware updates are impossible - choose this family only when the firmware is final. For in-application reprogrammability, designers should migrate to the flash-based PIC16F57 family instead. This page consolidates distributor pricing, drop-in same-package alternatives, and engineering design notes not found in the manufacturer datasheet alone, giving procurement and design engineers a single reference for evaluating the PIC16C57CT-04/SS.

PIC16C57CT-04E/SO

PIC16C57CT-04E/SO - 8-Bit 4MHz OTP MCU 3KB 28-SOIC | Microchip

The Microchip Technology PIC16C57CT-04E/SO is an 8-bit CMOS microcontroller from the PIC16C5X family, featuring 3KB (2K x 12) of One-Time Programmable (OTP) program memory and 72 bytes of RAM in a 28-pin SOIC wide-body package. It operates at a maximum clock speed of 4 MHz with a 100 ns instruction cycle, executes 33 single-word RISC instructions, and supports up to 20 digital I/O pins. An 8-bit microcontroller (MCU) is a small computing-on-a-chip that integrates a CPU, RAM, program memory, and peripherals into a single package. Within the taxonomy, it sits under microcontroller -> embedded processor -> semiconductor device. The PIC architecture uses a Harvard design with separate program and data buses, a 12-bit-wide instruction word, and a fixed-length instruction set that delivers roughly 2:1 code density over typical 8-bit CISC MCUs of its era. PIC16C5X parts were introduced as low-cost, high-volume OTP microcontrollers for appliances, automotive subsystems, and industrial control. Key features include 3KB OTP program memory (2K x 12 organization), 72 bytes of general-purpose RAM, 20 digital I/O lines arranged in three ports (RA, RB, RC), two 8-bit timers (TMR0 and TMR2), a Watchdog Timer with on-chip RC oscillator, Power-on Reset, Brown-out Reset, and an internal 4 MHz RC oscillator option. The device operates from 3.0 V to 6.0 V and is offered in commercial and industrial temperature grades. Architecturally, the PIC16C57C uses a RISC-style 12-bit instruction word with a two-stage pipeline, a single accumulator (W register) plus 32 general-purpose file registers, and CMOS EPROM/OTP program memory. Power-down (SLEEP) mode drops quiescent current below 1 µA typical, making it attractive for battery-backed designs. The PIC16C5X delivers an instruction execution time of 100 ns at 4 MHz, with most instructions completing in a single cycle. Typical applications include white-goods and appliance control, automotive body modules (cluster, lighting), industrial control timers, security and alarm panels, sensor signal conditioning, and low-cost consumer remote controls. The 28-SOIC wide-body package and 4 MHz clock are well suited to designs that need moderate compute, low cost, and surface-mount assembly. Designers should note that PIC16C5X code written for the PIC16C57 will not directly run on PIC16C55 or PIC16C56 (different memory maps and pinouts) and that the OTP program memory cannot be erased, so firmware must be validated on a windowed PIC16C57/JW or a compatible flash device such as PIC16F57 before production programming.

PIC16C57CT-04I/SO

PIC16C57CT-04I/SO - 4MHz 8-Bit OTP MCU, 3KB, 20 I/O | Microchip

The Microchip Technology PIC16C57CT-04I/SO is an 8-bit CMOS OTP-based microcontroller from the PIC16C5X family, delivering 4 MHz instruction execution with 100 ns instruction cycle time in a 28-pin SOIC package. It integrates 3 KB (2K x 12) of one-time-programmable program memory, 72 bytes of RAM, and 20 digital I/O pins, making it a cost-effective solution for embedded control. The "C" suffix denotes the CMOS EPROM/OTP variant of the original PIC16C57 family, while the "T" tape-and-reel suffix, "-04" 4 MHz speed grade, and "I" industrial temperature range (-40C to +85C) are reflected in the part number. A PIC16C5X microcontroller is an 8-bit fully-static CMOS RISC architecture device designed for low-cost, high-performance embedded control. Within the broader semiconductor taxonomy it sits as: 8-bit microcontroller -> microcontroller -> embedded processor -> semiconductor IC. The PIC16C5X core is Harvard-architecture with 12-bit-wide instructions, providing 2:1 code compression over comparable 8-bit CISC controllers in the same price class. With only 33 single-word instructions, programming complexity is minimal and code density is high, which lowers BOM cost in volume production. Key features of the PIC16C57CT-04I/SO include a 4 MHz maximum clock, 100 ns instruction execution, 3 KB (2K x 12) OTP program memory, 72 bytes of general-purpose RAM, a reset input, watchdog timer, and 20 bidirectional I/O pins. The 28-pin SOIC (SO) industrial package provides a surface-mount footprint compatible with hand-soldering and standard reflow profiles. Power consumption is low for an OTP CMOS MCU of its era, with the static core supporting fully static operation that allows the clock to be stopped without losing register state. Architecturally the PIC16C57CT uses a two-stage pipeline and a 12-bit program memory bus with an 8-bit data bus. Unlike later PIC16 mid-range parts, the PIC16C5X family does not feature interrupts, which simplifies real-time control loops because timing is fully deterministic from instruction counting. The OTP memory allows factory programming or one-time field programming via a device programmer, which is commonly used for low-volume production runs or end-of-line customization where mask-ROM volumes are uneconomical. Typical applications include appliance control, sensor signal conditioning, low-end consumer electronics, industrial timers and counters, automotive body controllers (legacy systems), simple LED driving, and remote-control transmitters. The 20 I/O pins and 33-instruction set enable direct interfacing to keypads, seven-segment displays, and discrete analog signals via simple RC networks. The wide industrial temperature range also supports outdoor or factory-floor deployments. When designing with the PIC16C57CT-04I/SO, plan the program memory as OTP - code must be 100% verified before programming because there is no in-circuit reprogramming. Use a Watchdog Timer to recover from brown-out events, add a decoupling capacitor of 0.1 uF close to VDD, and reserve an RC network on MCLR for clean reset behavior. The -04 speed grade means the oscillator must be selected to keep instruction execution within the 100 ns cycle budget at the chosen VDD.

The SSOP-28 footprint provides 20 usable I/O lines in a compact 5.30 mm body. Typical applications include low-cost embedded controllers, automotive body and interior modules, white goods and appliance control, industrial sensor conditioning, simple PWM driver stages, and replacement of discrete logic glue. The wide temperature range and rugged CMOS design also suit HVAC controls, smart sensors, and small consumer appliances. When designing with this device, ensure the EPROM programming step is included in your manufacturing flow because the -04I/SS suffix denotes a windowless (one-time-programmable) industrial-temperature grade. The 'C' suffix denotes the CMOS revision, and '04' denotes the 4 MHz oscillator variant (which still scales to 40 MHz instruction rate via the internal 4x PLL-style clock chain on this family).

It executes instructions at 100ns per instruction cycle using a 12-bit wide RISC instruction set, providing 2:1 code compression over competing 8-bit microcontrollers in the same price category. The device operates from 4.5V to 5.5V single supply at a maximum clock rate of 20 MHz. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, RAM, non-volatile program memory, and peripheral I/O. The PIC16C5X architecture specifically belongs to the PIC (Peripheral Interface Controller) family, characterized by Harvard architecture with separate program and data buses, RISC instruction sets, and OTP/EPROM program memory for low-cost, high-volume embedded designs. In the broader system hierarchy, MCUs sit below microprocessors (MPUs) and above discrete logic ICs in the embedded computing taxonomy, forming the backbone of consumer appliances, automotive subsystems, and industrial controllers where deterministic real-time response and minimal BOM cost are paramount. Key features of the PIC16C57CT-20I/SO include 33 single-word instructions, an 8-bit timer/counter, watchdog timer for code execution integrity, 20 bidirectional I/O pins capable of source/sink up to 25 mA per pin for direct LED drive, and a 12-bit instruction word that simplifies instruction decoding. The device also features a power-on reset (POR) circuit, brown-out detection, and a programmable code-protection mechanism to safeguard firmware IP. CMOS fabrication yields typical operating current under 2 mA at 5V/4 MHz and standby current below 1 uA, well-suited for battery-backed appliances. From an architectural perspective, the PIC16C5X implements a two-stage pipeline with single-cycle instruction fetch (except for program branches), allowing deterministic 100ns instruction execution at 20 MHz. The 8-level hardware stack and direct/indirect addressing modes simplify C and assembly firmware porting from earlier PIC16C5X designs. Program memory is one-time programmable (OTP) via EPROM cells, which historically offered faster prototyping than mask-ROM during low-volume product ramps. Typical applications for the PIC16C57CT-20I/SO include white-goods and appliance controllers, security keypads and alarm panels, automotive interior accessories (non-safety-critical), consumer IR remote controls, and industrial sensor interface modules. Its industrial temperature rating makes it appropriate for factory-floor sensor conditioning where consumer-grade MCUs would fail. When designing with this part, note that OTP memory cannot be electrically erased and is not suited for firmware that requires frequent field updates; consider the flash-based PIC16F57 as a development upgrade path. The 28-SOIC wide-body footprint (7.50 mm) is pin-compatible with the PIC16C57C family, allowing easy migration between commercial (PIC16C57C-20/SO), industrial (PIC16C57CT-20I/SO), and extended (PIC16C57C-20E/SO) temperature grades.

OTP MCUs sit inside the broader taxonomy of microcontroller -> embedded controller -> semiconductor, and they are commonly chosen for cost-optimized, high-volume applications where field firmware updates are not required. The PIC architecture pioneered by Microchip uses 12-bit-wide, highly orthogonal instructions to deliver roughly 2:1 code compression versus competing 8-bit cores, so 3 KB of OTP can address surprisingly complex control tasks. Key features include a 33-instruction RISC set, only 2 special-function registers to configure interrupts and I/O direction, a watchdog timer with on-chip RC oscillator for fail-safe recovery, a power-on reset circuit, and an industrial-grade -40C to +85C operating range. The 20 MHz oscillator drives a four-clock-per-instruction pipeline that sustains 5 MIPS throughput, more than adequate for sensor conditioning, simple human-machine interfaces, and stepper or solenoid control loops. Typical applications include automotive body modules, appliance controls, security keypads, low-end remote controls, and battery-powered instruments where unit cost and deterministic behavior outweigh the need for in-system reprogrammability. The 28-SSOP footprint makes the part drop-in compatible with several PIC16C5X and PIC16C55 family variants, simplifying multi-platform qualification. When designing with this part, allocate the MCLR pin to a proper reset network and respect the OTP programming window because OTP parts cannot be reprogrammed. Use the watchdog timer for unattended operation and ensure the supply rail stays within 3.0 V to 5.5 V, including load-dump transients on 12 V automotive buses. This page synthesizes verified distributor pricing, drop-in compatible variants, and practical design guidance drawn from Microchip PIC16C5X family documentation to help procurement and embedded engineers evaluate, source, and deploy this long-life classic MCU.

PIC16C57CT-40/SO

PIC16C57CT-40/SO - 8-bit 40MHz OTP MCU, 3KB | Microchip

The Microchip Technology PIC16C57CT-40/SO is an 8-bit RISC microcontroller from the PIC16C5X family, housed in a 28-pin SOIC (Small Outline IC, 0.295 inch / 7.50 mm body width) surface-mount package. It integrates 3 KB of OTP (One-Time Programmable) program memory organized as 2K x 12 words, 72 bytes of RAM, and runs the PIC instruction set at a maximum clock rate of 40 MHz, yielding a 100 ns instruction cycle. The device exposes 20 general-purpose digital I/O pins and includes Power-On Reset (POR) and Watchdog Timer (WDT) peripherals, making it well-suited to cost-sensitive embedded control. A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory (program + data), and peripheral interfaces. The PIC16C5X family belongs to the original baseline PIC architecture, classified within 8-bit microcontrollers -> RISC microcontrollers -> embedded controllers -> semiconductors. Its 12-bit-wide instruction word delivers roughly 2:1 code compression versus 8-bit CISC MCUs in the same class, allowing dense application code in compact flash/OTP arrays. Key features include 33 single-word instructions, a 2-level hardware stack, 8-bit timer/counter (TMR0), and direct/indirect addressing modes. The 28-SOIC package provides gull-wing leads for standard surface-mount assembly. Power supply range is 2.5 V to 6.25 V (commercial grade), and ESD/EMI characteristics are designed for industrial and consumer environments. The 'C' revision silicon supersedes the original PIC16C57 with improved electrical performance and lower power consumption. Typical applications include appliance controls, simple sensor interfaces, low-cost consumer electronics, and automotive sub-system retrofits. The 20 I/O pins support keypad scanning, LED driving, and parallel slave-mode communication to a host processor. The combination of OTP memory, 40 MHz operation, and 28-SOIC footprint makes the PIC16C57C a long-lifecycle component for production designs. Design considerations: OTP memory cannot be re-programmed, so code must be fully validated before device programming. A series termination resistor on MCLR may improve noise immunity, and decoupling caps (100 nF + 10 uF) should be placed close to VDD/VSS. For new designs, consider the flash-based PIC16F57 equivalent for in-circuit reprogrammability.

It integrates 3 KB (2 K x 12) of One-Time Programmable (OTP) program memory and 72 bytes of data RAM, optimized through 33 single-word instructions that yield roughly 2:1 code compression over competing 8-bit MCUs in the same price class. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, memory, and peripherals around an 8-bit data bus. The PIC16C5X family belongs to the broader class of RISC microcontrollers -> microcontrollers -> embedded processors -> semiconductor ICs, where the OTP program memory variant is favored for cost-sensitive, low-to-medium volume production runs that still need firmware flexibility during prototyping. Key features of the PIC16C57CT-40/SS include two 8-bit timers (TMR0 and TMR2), a Watchdog Timer (WDT) for code-flow integrity, Power-on Reset (POR) and Brown-out Reset (BOR) for reliable startup, an integrated RC oscillator option to eliminate external clock hardware, and CMOS process technology for low power consumption. The 40 MHz maximum operating frequency corresponds to a 100 ns instruction cycle, supporting deterministic real-time control tasks. Architecturally, the device uses a 12-bit instruction word with a Harvard-style bus split between program memory (12-bit wide) and data RAM (8-bit wide). It offers up to 20 I/O pins depending on package, and operates across a 3.0 V to 5.5 V supply range with commercial temperature grade (0 °C to +70 °C).

PIC16C57T-10/SO - 8-Bit 10MHz OTP MCU 3KB | Microchip

The Microchip Technology PIC16C57T-10/SO is an 8-bit RISC microcontroller from the PIC® 16C family, featuring a 10 MHz maximum clock speed, 3 KB (2K x 12) of One-Time-Programmable (OTP) program memory, and 72 bytes of on-chip data RAM, housed in a 28-pin SOIC (SO) wide-body package. It integrates a PIC CPU core, 20 digital I/O lines, Power-On Reset (POR), a Watchdog Timer (WDT), and an 8-bit timer/counter for embedded control tasks. The 'T-10' suffix designates the 10 MHz speed grade and tape-and-reel packaging on the SOIC variant, while the commercial 0C to +70C temperature grade makes it suitable for benign operating environments. This CMOS EPROM-based device belongs to the PIC16C5X family, which is renowned for its 12-bit wide, highly orthogonal instruction set that delivers 2:1 code compression over competing 8-bit microcontrollers in its class. A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory (program + data), and programmable I/O peripherals on one die, enabling compact, low-cost embedded control. The PIC16C5X sits within the broader hierarchy: microcontroller -> embedded processor -> semiconductor -> integrated circuit. OTP (One-Time-Programmable) program memory means the firmware is written once at production time and cannot be erased, which lowers per-unit cost compared to Flash-based parts at the expense of field-upgradability. Key features include 2:1 code compression from its 12-bit orthogonal instruction set, 33 single-word/single-cycle instructions (except for program branches which are two-cycle), a fully static design supporting DC operation, and a wide operating voltage range of 2.0V to 6.25V. The 28-SOIC wide-body footprint provides easier hand-soldering and stronger thermal performance than the SSOP variant, while the integrated WDT and POR eliminate external supervisory components and reduce BOM cost. The PIC16C57T-10/SO is engineered around Microchip's classic PIC16C5X RISC architecture, which separates program and data buses (Harvard architecture) and uses a 12-bit instruction word to balance code density with execution speed. The 10 MHz oscillator input yields a 100 ns instruction cycle, sufficient for slow-control applications such as keypad scanning, simple sensor interfacing, and LED multiplexing. Typical applications include consumer appliance controllers, low-end automotive body electronics, battery chargers, simple sensor signal conditioning, HVAC fan controllers, and educational/hobbyist microcontroller platforms. The wide 28-SOIC package simplifies prototyping on through-hole adapter boards for both hobbyists and engineers validating legacy designs. When designing with this part, note that OTP memory cannot be re-programmed in-circuit - firmware must be fully validated before committing. The 10 MHz speed grade is appropriate for sub-1 MIPS control tasks; designers needing higher throughput should consider PIC16C55A or PIC16C57C variants operating at 20 MHz or 40 MHz. Always consult Microchip's PIC16C5X datasheet and PinPack compatibility chart (DS00148J2) for cross-family pin and code equivalence.

PIC16C57T-10/SS

PIC16C57T-10/SS - 8-Bit 10MHz 3KB OTP MCU 28-SSOP | Microchip

The Microchip Technology PIC16C57T-10/SS is a member of the PIC16C5X family of low-cost, high-performance, 8-bit fully-static EPROM/ROM-based CMOS microcontrollers, delivering 10 MIPS performance at a 10 MHz clock in a 28-pin SSOP package. The device integrates 3 KB (2K x 12) of One-Time Programmable (OTP) program memory, 72 bytes of general-purpose RAM, and 20 digital I/O pins organized across multiple ports. Operating from a 4.5 V to 5.5 V single supply, the PIC16C57T-10/SS supports the standard PIC16C5X instruction set with 12-bit wide, highly symmetrical opcodes that deliver 2:1 code compression over other 8-bit microcontrollers in its class. A microcontroller (MCU) is a single-chip computer that contains a CPU, program memory, data memory, and I/O peripherals. Within the broader taxonomy, the PIC16C57T-10/SS is a Harvard-architecture 8-bit RISC microcontroller in the legacy PIC16C5X base-line family, which sits under the umbrella of embedded controllers and semiconductor ICs. The 'T' suffix denotes tape-and-reel packaging for high-volume SMT assembly, while '/SS' specifies the 28-pin SSOP (5.30 mm body width) footprint. Key features include a 10 MHz external oscillator, internal watchdog timer, power-on reset, brown-out detection, and an 8-bit timer/counter with programmable prescaler. The device consumes only 2 mA typical at 5 V / 10 MHz and supports four oscillator modes (RC, LP, XT, HS) to trade off power versus clock accuracy. The 20 I/O pins can directly sink/source up to 25 mA per pin, enabling direct LED drive and eliminating external driver buffers in many cost-sensitive designs. Architecturally, the PIC16C57T-10/SS uses a 12-bit instruction word with separate program and data buses, a 2-stage pipeline, and a 33 single-word instruction set. The OTP program memory allows one-time field programming for low-NRE prototypes and short production runs; for high-volume runs, Microchip offers mask-ROM (-10/SS with no 'T') equivalents. Compared to flash-based successors such as the PIC16F57, the OTP die provides lower cost at the expense of non-erasable code storage. Typical applications include appliance control, security-system keypads, HVAC fan controllers, battery chargers, simple sensor interfaces, and white-goods user-interface boards. Its wide operating temperature range and EPROM-based reliability make it especially suited to industrial-grade equipment where long-term firmware stability is required. The 28-SSOP package balances compactness with hand-solder-friendly lead pitch for low-volume production. When designing with this part, allocate the I/O budget early - 20 pins must cover all keypad scanning, LED driving, and sensor I/O. Because OTP memory cannot be updated in the field, design the firmware revision flow to use windowed EPROM prototypes (PIC16C57-10/P in CERDIP) before committing to OTP production. The 'T' suffix indicates tape-and-reel only, not a different temperature grade; the standard part operates over 0°C to +70°C commercial range.

The Microchip Technology PIC16C57T-10E/SO is an 8-bit RISC OTP (One-Time Programmable) microcontroller from the PIC16C5x family, offering 3KB of program memory (2K x 12) and operating at up to 10MHz in a 28-pin SOIC (SO) package. It is part of Microchip's classic baseline PIC architecture designed for cost-sensitive embedded control applications. The PIC microcontroller is an 8-bit RISC (Reduced Instruction Set Computer) Harvard-architecture device originally introduced by General Instrument's Microelectronics Division and later popularized by Microchip Technology. The PIC16C5x family is one of the earliest baseline PIC families, featuring a 12-bit instruction word, 2:1 code compression versus competitive 8-bit MCUs, a two-stack hardware subroutine call depth, and a fixed instruction set optimized for compact code generation. These devices typically integrate EPROM/OTP program memory, RAM data memory, and digital I/O on a single CMOS die, serving as the system-on-chip foundation for countless appliances, toys, and industrial controllers since the late 1990s. Key features of the PIC16C57T-10E/SO include 3KB (2K x 12) of OTP program memory, 72 bytes of RAM data memory, 20 digital I/O pins, a wide operating voltage range of 2.5V to 6.0V, and an industrial temperature range of -40C to +125C. The 'T' suffix denotes tape and reel packaging, '10' indicates 10MHz maximum clock, 'E' designates the extended industrial temperature grade, and 'SO' specifies the 28-pin SOIC wide-body package. The device uses a two-stage instruction pipeline and operates from a single oscillator reference (RC, XT, HS, or LP modes). Typical applications include appliance controls, simple sensor interfaces, LED driving circuits, motor control signal generation, battery chargers, security keypads, automotive body electronics, and replacement of discrete logic in cost-driven embedded systems. The combination of low unit cost, deterministic instruction timing, and Microchip's mature development toolchain (MPLAB) keeps the PIC16C5x relevant in long-lifecycle industrial designs. Design considerations include OTP memory one-time programmability (requires pre-programming before PCB assembly), limited 72-byte RAM restricting data buffer sizes, only two hardware stack levels limiting nested subroutine depth, and the absence of on-chip peripherals like ADC or PWM (must be implemented externally). The 28-SOIC wide-body footprint (7.50mm) is pin-compatible with later flash-based PIC16F variants, easing migration paths to modern, reprogrammable alternatives.

PIC16C57T-10I/SO

PIC16C57T-10I/SO - 8-Bit 10MHz OTP MCU 28-SOIC | Microchip

The Microchip Technology PIC16C57T-10I/SO is an 8-bit CMOS RISC microcontroller from the PIC® 16C family, supplied in a 28-pin SOIC package and qualified for the -40C to +85C industrial temperature range. It integrates 3KB (2K x 12) of One-Time Programmable (OTP) EPROM program memory, 72 bytes of RAM, 20 general-purpose digital I/O pins, and a 10 MHz internal/external clock domain. The "T" suffix denotes tape-and-reel packaging while the "I" suffix specifies the industrial operating temperature grade, and the "/SO" package code maps to a 28-pin 7.50 mm wide small-outline IC. An 8-bit microcontroller (MCU) is a single-chip computer that combines a CPU, RAM, non-volatile program memory, and peripheral I/O on one die; OTP variants let OEMs pre-program the device in production at lower cost than windowed EPROM while still retaining one-time field customization. The PIC16C5X family targets high-volume cost-sensitive embedded control where deterministic instruction execution, low power, and minimal external component count matter more than raw arithmetic performance. Architecturally, it sits below 16-bit MCUs and far below 32-bit Cortex-M devices but above pure logic-replacement state machines in capability. Key differentiating features of the PIC16C57T-10I/SO include a 12-bit instruction word with 33 single-word/single-cycle instructions (giving a 2:1 code compression advantage over competing 8-bit MCUs), a fully static CMOS design supporting DC to 10 MHz operation, two 8-bit timer/counters (TMR0 and TMR2-style counter), a watchdog timer, and 20 mA sink capability per I/O for direct LED drive. The Harvard architecture separates program and data buses, eliminating fetch conflicts. Internal RC oscillator options and on-chip power-on reset reduce external component count to a single decoupling capacitor in many applications. Typical applications include appliance control boards, automotive body electronics (non-safety), consumer remote controls, security keypads, smart card readers, LED display controllers, battery chargers, and small sensor-interface nodes. The wide 2.5V-5.5V supply range, robust I/O, and OTP memory model also suit industrial telemetry, instrumentation front-ends, and legacy equipment retrofits where pin-compatible PIC16C5X sockets already exist on the PCB. A key design trade-off: OTP EPROM cannot be reprogrammed in-circuit, so engineers must use a windowed PIC16C57 (e.g., PIC16C57-10/JW) for prototype development and reserve the OTP /SO variant for production runs.

A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, data memory, and programmable I/O peripherals into one package. Within the broader taxonomy, this part belongs to: 8-bit microcontroller -> RISC microcontroller -> embedded controller -> microcontroller unit -> semiconductor IC. PIC16C5X devices implement a Harvard-architecture RISC core with 33 single-cycle instructions and a 12-bit-wide instruction word, delivering roughly 2:1 code compression over competing 8-bit CISC MCUs in its class. Key features of the PIC16C57T-10I/SS include 8-bit timer/counter resources, a watchdog timer with on-chip RC oscillator, power-on reset, and an internal/external oscillator selection. The OTP EPROM memory allows field programming during prototyping and low-volume production, and the SSOP-28 footprint (5.30 mm body width) makes it suited for space-constrained boards where a PDIP would be too large. The "T" suffix denotes tape-and-reel packaging for high-volume assembly, while the "-10" speed grade specifies the 10 MHz maximum clock. Typical applications include white-goods and appliance control, automotive body electronics (non-safety), industrial sensor interfaces, simple user-interface panels, and remote-control transmitter logic. The wide operating voltage range and low-power CMOS design also suit battery-powered embedded nodes where deterministic behavior matters more than compute throughput.

The part operates from a 5V supply and provides 20 general-purpose digital I/O lines. A PIC16C5X microcontroller is a member of the low-cost, high-performance, fully-static 8-bit OTP/EPROM/ROM controller family that uses a 12-bit-wide instruction set. The "base-line" PIC architecture uses a RISC-style instruction set with a small fixed number of single-cycle instructions (excluding branches), 2:1 code compression versus competitive 8-bit controllers in the same price class, and direct register-mapped I/O. Positioned as the simplest member of the PIC16 family, the PIC16C57T-HS/SO typically finds use in cost-sensitive embedded control applications such as consumer appliances, sensor interfaces, and simple state machines.

The wide operating voltage range and CMOS low-power design make the device suitable for both battery-powered and line-powered equipment. Architecturally, the PIC16C57 uses a Harvard-class two-bus design where program and data memory are accessed through separate paths, allowing an instruction fetch and a data access to occur in the same clock cycle. This two-stage pipeline is what gives the PIC16C5X family its 4:1 effective speed advantage over conventional CISC 8-bit controllers at the same clock rate. The OTP program memory is one-time programmable but allows prototype and production programming flexibility that mask-ROM parts do not. Typical applications include simple motor control, LED display drivers, security-system sensor interfaces, appliance control boards, remote-control transmitters, and low-cost consumer electronics. Its 20 I/O pins make it well-suited to applications that need to read multiple switches or drive several outputs simultaneously. When designing with the PIC16C57T-HS/SO, engineers should note that OTP memory cannot be erased; engineering samples should use the PIC16F57 (Flash-based) or a windowed CERDIP PIC16C57 for development. The HS oscillator mode requires an external clock source up to 20MHz, and decoupling capacitors (100nF plus bulk) close to VDD/VSS pins are mandatory.

PIC16C57T-LP/SO - 8-bit OTP MCU, 3KB, 40MHz, 28-SOIC | Microchip
PIC16C57T-LP/SO

PIC16C57T-LP/SO - 8-bit OTP MCU, 3KB, 40MHz, 28-SOIC | Microchip

The Microchip PIC16C57T-LP/SO is an 8-bit RISC microcontroller in the PIC® 16C family, offering 3KB (2K x 12) of One-Time-Programmable (OTP) program memory, 72 bytes of data RAM, and a maximum clock speed of 40MHz, all housed in a 28-pin SOIC package. The "/SO" suffix denotes the 7.50 mm (0.295") wide SOIC surface-mount variant, while the "T" indicates tape-and-reel packaging and "LP" specifies the low-power oscillator operating mode. Together, these features make the PIC16C57T-LP/SO a compact, cost-effective MCU for high-volume embedded applications. An 8-bit microcontroller (MCU) is a small, self-contained computing element built around an 8-bit data path, integrating a CPU, program memory (ROM/OTP/Flash), data RAM, and peripherals such as timers, reset circuitry, and I/O ports on a single silicon die. Microcontrollers sit within the broader semiconductor hierarchy: 8-bit MCU -> microcontroller -> embedded processor -> integrated circuit. The PIC® 16C series from Microchip uses a RISC-based Harvard architecture with 12-bit-wide instructions, providing 2:1 code compression versus competing 8-bit MCUs in its class. Key features of the PIC16C57T-LP/SO include 20 general-purpose I/O pins arranged across three ports (RA, RB, RC), Power-On Reset (POR) for deterministic startup, a Watchdog Timer (WDT) for software fault recovery, and a low-power LP oscillator mode that reduces current consumption in battery-driven designs. The device operates from a single 5V supply (typical 2.5V to 6.0V range) and consumes relatively low current due to its CMOS process technology. The 28-SOIC package provides the largest pin count in the PIC16C5x family, exposing more I/O than smaller 18-pin variants. The PIC16C57T-LP/SO uses a RISC instruction set with only 33 single-word/single-cycle instructions (excluding branches), enabling predictable execution timing that simplifies assembly programming. Unlike Flash-based MCUs, OTP memory is programmed once and cannot be erased, making the part attractive for low-cost production runs where firmware is finalized and volume pricing dominates. The LP oscillator mode is intended for use with low-frequency (e.g., 32.768 kHz to 200 kHz) crystals, ideal for low-power timekeeping or sleep-dominated duty cycles. Typical applications include low-cost consumer appliances, remote-control transmitters, simple sensor interfaces, battery-powered toys, LED controllers, and industrial timer modules. The wide SOIC footprint also makes it well suited for hobbyist and educational use, breadboard prototyping, and legacy equipment repair. When designing with this part, note that OTP memory cannot be re-programmed during development - prototype with the PIC16C57-LP/SO (UV-erasable) or modern Flash-based PIC16F equivalents before committing. Also confirm that the LP oscillator mode pairs with a low-frequency external crystal; for high-frequency designs the HS or RC mode is required.

PIC16C57T-LP/SS - 8-bit OTP MCU 3KB 20 I/O SSOP-28 | Microchip
PIC16C57T-LP/SS

PIC16C57T-LP/SS - 8-bit OTP MCU 3KB 20 I/O SSOP-28 | Microchip

The Microchip Technology PIC16C57T-LP/SS is an EPROM/ROM-based 8-bit CMOS microcontroller from the PIC16C5X family, supplied in a 28-pin SSOP (5.30 mm body width) package on tape-and-reel. It integrates 3 KB of OTP program memory (organized as 2K x 12), 72 bytes of general-purpose RAM, and 20 digital I/O pins, and executes instructions at up to 40 MHz from a 5 V supply. The "T" suffix indicates the SSOP tape-and-reel shipping format, while "LP" denotes the low-power CMOS process and "/SS" confirms the SSOP package. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, memory, and programmable I/O on one die. The PIC16C5X family uses a RISC architecture with 33 single-word/single-cycle instructions, which simplifies firmware development and accelerates interrupt latency compared with legacy CISC 8-bit controllers. OTP (One-Time-Programmable) memory means the part is programmed once and retains code without a battery, which keeps unit cost low and fits well in cost-sensitive, mid-volume embedded products. Key features of the PIC16C57T-LP/SS include 12-bit instruction width, a hardware 8-bit timer with optional prescaler, a watchdog timer with dedicated on-chip RC oscillator, power-on reset, and four oscillator options (RC, XT, HS, LP). The LP oscillator mode is optimized for low-power 32.768 kHz crystal operation, and the device supports a commercial temperature range of 0C to +70C. Because the program memory is OTP rather than flash, designers must commit firmware before device programming, which is a deliberate trade-off between unit cost and re-programmability. Typical applications include low-cost consumer appliances, simple motor and relay control boards, sensor signal conditioning front-ends, and any volume production where a small RISC controller is sufficient. The wide 2.0 V to 6.0 V supply range simplifies designs powered by unregulated 3 V or 5 V rails. When designing with the PIC16C57T-LP/SS, validate oscillator start-up margins in LP mode and confirm that the OTP programming window is closed before in-circuit verification. Place a 0.1 uF decoupling capacitor as close as possible to VDD and use bulk capacitance on MCLR to keep the reset line clean during in-circuit serial programming. This page synthesizes distributor pricing, parametric alternatives, and practical design notes that are not collected in the manufacturer datasheet alone, providing an independent view for engineers selecting a PIC16C5X family MCU.

PIC16C57T-LPE/SO - 8-Bit OTP MCU, 3KB, 40MHz, 28-SOIC | Microchip
PIC16C57T-LPE/SO

PIC16C57T-LPE/SO - 8-Bit OTP MCU, 3KB, 40MHz, 28-SOIC | Microchip

The Microchip Technology PIC16C57T-LPE/SO is an 8-bit EPROM/ROM-based CMOS microcontroller belonging to the PIC® 16C family, packaged in a 28-pin SOIC (7.50 mm width) with low-power and extended-temperature characteristics. The device integrates 3 KB of One-Time Programmable (OTP) program memory organized as 2K x 12 words, 72 bytes of RAM, and 20 general-purpose I/O pins, while running from a single 3 V to 5.5 V supply. The 'T' suffix denotes the tape-and-reel shipping format and the 'LP' code indicates a low-power CMOS process with the 'E' temperature grade. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, working RAM, and peripheral interfaces on one die, and is the foundational building block of embedded systems. The PIC16C5X family specifically occupies the legacy 8-bit RISC tier of Microchip's portfolio, sitting below the PIC16F and PIC18 mid-range families in both program memory and peripheral sophistication. It is used wherever engineers need deterministic, low-cost, OTP-based control with a minimal instruction set of only 33 single-word, single-cycle instructions. Key features of the PIC16C57T-LPE/SO include an 8-bit accumulator-based Harvard architecture, a 4 MHz nominal oscillator input (with internal divide yielding a 1 MHz instruction cycle at 4 MHz clock), an 8-bit real-time clock/counter (RTCC) with 8-bit prescaler, a Watchdog Timer (WDT) with its own on-chip RC oscillator for reliable operation, and a Power-On Reset (POR) circuit. The low-power 'LP' process allows supply current well below 1 mA in active mode at low clock rates, making the part suitable for battery-influenced designs. Twenty bidirectional I/O pins arranged across ports A, B and C can source or sink current directly to drive LEDs, relays and small solenoids. Typical applications for this device include simple appliance control, remote keyless-entry transmitters, low-end consumer electronics, HVAC sequencers, security keypads, and other cost-sensitive embedded products where OTP programmability is acceptable in production volumes. The device is also widely used as an educational platform for embedded-systems courses that teach the original PIC instruction set and Harvard memory model. Because the program memory is OTP rather than flash, it is preferred for high-volume production runs rather than engineering prototypes that require frequent code revisions. When designing with the PIC16C57T-LPE/SO, designers should note that the legacy 12-bit instruction word requires assembly or compiler tools that explicitly target the PIC16C5X core (modern MPLAB XC8 supports the family in legacy compatibility mode). Watchdog Timer software servicing must be included to recover from transient upsets in electrically noisy environments such as motor-control or relay-driven loads.
