PIC16C57-10I/SO - 8-Bit 10MHz OTP MCU 3KB | Microchip
PIC16C57-10I/SO

PIC16C57-10I/SO - 8-Bit 10MHz OTP MCU 3KB | Microchip

The Microchip Technology PIC16C57-10I/SO is an 8-bit CMOS microcontroller from the PIC16C5X family, delivering 10 MIPS performance at 10 MHz clock with 3 KB (2K x 12) of One-Time-Programmable (OTP) program memory and 72 bytes of RAM, housed in a 28-pin SOIC (0.295", 7.50 mm width) package. The industrial-grade "-I" suffix denotes an operating temperature range of -40 °C to +85 °C, making the part suitable for harsh-environment embedded designs. An 8-bit microcontroller (MCU) is a small computer-on-a-chip integrating an 8-bit CPU core, program memory (ROM/EPROM/Flash/OTP), data RAM, and peripherals such as timers, I/O ports, and interrupts. Within the broader taxonomy, the PIC16C57 belongs to the 8-bit MCU -> microcontroller -> embedded processor -> semiconductor device family. The "C" suffix indicates CMOS EPROM-based program memory, while the "OTP" variant allows a single user programming cycle, ideal for low-to-medium volume production runs where mask-ROM NRE costs are uneconomical. Key features include 20 digital I/O pins organized across ports RA-RC, a single 8-bit Timer0 (TMR0) with programmable prescaler, a two-level deep hardware stack, and Harvard architecture with 12-bit wide instructions and 8-bit data path. The PIC16C57 supports 33 single-word instructions, DC to 10 MHz operation, and offers 4 oscillator modes (RC, LP, XT, HS) for design flexibility across low-power and high-speed clocking. Watchdog timer and power-on reset enhance field reliability, and the 8-bit real-time clock/counter supports event timing without software overhead. Typical applications include appliance control, automotive body electronics, industrial sensor interfaces, low-end consumer products, smart sensors, LED lighting controllers, and battery-powered embedded systems. The wide operating voltage (typically 2.5 V to 6.0 V) and low power consumption suit both line-powered and battery-backed designs. When designing with the PIC16C57, note that the OTP memory cannot be re-programmed, so production code must be validated on EPROM-windowed (JW) samples first. The 2-level hardware stack limits subroutine nesting to two levels - C compilers and high-level languages are not supported, and the developer must write in PIC assembly or use a state-machine coding style.

PIC16C57-10I/SP - 8-Bit 10MHz 3KB OTP MCU 28-SPDIP | Microchip
PIC16C57-10I/SP

PIC16C57-10I/SP - 8-Bit 10MHz 3KB OTP MCU 28-SPDIP | Microchip

The Microchip Technology PIC16C57-10I/SP is a member of the PIC16C5X family of low-cost, high-performance 8-bit fully-static EPROM-based CMOS microcontrollers. Operating at up to 10 MHz, the device integrates 3 KB of OTP program memory (2K x 12 organization), 72 bytes of RAM, and 20 digital I/O pins in a 28-pin SPDIP (Skinny Plastic DIP) through-hole package. The "/SP" suffix denotes the SPDIP package, "-10" indicates the 10 MHz speed grade, and "I" indicates the industrial operating temperature range of -40 °C to +85 °C. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, working RAM, and peripheral I/O on one die. In the broader component taxonomy, the PIC16C57 sits below general-purpose microprocessors and above fixed-function logic ICs: it belongs to the 8-bit microcontroller class, within the PIC family, under the Integrated Circuits umbrella. 8-bit MCUs like the PIC16C57 dominate cost-sensitive, deterministic, low-power embedded applications where pin count, code density, and predictable interrupt latency outweigh raw throughput. Key features include a 12-bit wide instruction word with 8-bit data path, two-level deep hardware stack, direct/indirect/relative addressing modes, 8-bit real-time clock/counter (TMR0), and a programmable Watchdog Timer with on-chip RC oscillator. The PIC16C5X RISC architecture delivers 2:1 code compression versus typical 8-bit CISC MCUs of its class, enabling small-footprint firmware. Power consumption is characterized by < 2 mA typical operating current at 5 V and 10 MHz, with a < 1 µA standby current in Sleep mode. The device supports an oscillator frequency range of DC to 10 MHz and operates from 3.0 V to 6.0 V. Typical applications include industrial control systems, appliance controls, automotive subsystems (non-safety-critical), security and alarm panels, simple sensor interfaces, consumer electronics, and low-cost replacement of discrete logic. The wide 20-I/O count and small SPDIP footprint make it well suited to retrofits and legacy through-hole PCB designs where surface-mount conversion is impractical. When designing with the PIC16C57-10I/SP, ensure VDD decoupling with 0.1 µF ceramic capacitors close to the power pin, choose an oscillator topology (RC, XT, LP, or HS) matched to the application frequency, and allocate sufficient OTP programming margin. Note that OTP memory cannot be erased or rewritten; for in-circuit firmware iteration, the PIC16F57 flash variant is preferred.

PIC16C57-HS/P - 8-bit OTP MCU 20MHz 3KB | Microchip
PIC16C57-HS/P

PIC16C57-HS/P - 8-bit OTP MCU 20MHz 3KB | Microchip

The Microchip Technology PIC16C57-HS/P is an 8-bit CMOS RISC microcontroller from the PIC16C5X baseline family, featuring 20MHz maximum clock speed, 2K x 12 (3KB) of one-time programmable (OTP) program memory, and 72 bytes of data RAM in a 28-pin PDIP through-hole package. The 'HS' suffix denotes a high-speed oscillator variant supporting crystals up to 20MHz, while the '/P' package code indicates a 28-pin PDIP (Plastic Dual In-line Package) for prototyping and industrial through-hole designs. An OTP microcontroller is a variant of programmable microcontroller in which the program memory can be written once via a device programmer and is then non-volatile and non-erasable. The PIC16C57 belongs to the baseline PIC16 family hierarchy, which sits under the broader PICmicro 8-bit microcontroller taxonomy and ultimately under Microchip's PIC microcontroller portfolio. OTP parts sit alongside EPROM windowed, Flash, and ROM-based variants in the same silicon family, with OTP favored for cost-sensitive, high-volume production where field re-programmability is not required. Key features of the PIC16C57-HS/P include a 12-bit wide instruction word with 33 single-word/single-cycle instructions, a two-level deep hardware stack, eight-level deep hardware call stack, direct/indirect/relative addressing modes, a single 8-bit real-time clock/counter (TMR0) with 8-bit programmable prescaler, 20 digital I/O pins capable of sourcing/sinking up to 25mA per pin, watchdog timer with on-chip RC oscillator, power-on reset, power-saving SLEEP mode, and code-protect security fuse. Operating voltage is 3.0V to 5.5V with commercial and industrial temperature grades available. The architecture uses a Harvard-style RISC design with separate program and data buses, two 8-bit file-select registers (FSR) for indirect addressing, and seven or eight special function hardware registers mapped into a common I/O space. Throughput is approximately 5 million instructions per second at 20MHz, giving cycle times of 200ns - roughly 2:1 code compression over comparable 8-bit CISC microcontrollers in its class. Typical applications include consumer appliance controls, simple sensor interfaces, automotive body electronics (non-safety), battery chargers, low-end motor control loops, security keypads, and replacement of discrete logic in glue-logic consolidation designs. The 28-pin PDIP package remains popular for through-hole prototyping, educational platforms, and legacy industrial equipment where socketed replacement is required. When designing with this part, ensure the OTP programming step is integrated into the manufacturing flow because field firmware updates are impossible after programming. For designs requiring in-system reprogrammability, consider migrating to the pin-compatible PIC16F57 flash variant. This page synthesizes distributor pricing, drop-in alternatives within the same 28-pin PDIP footprint, and practical design notes not collected in any single manufacturer datasheet.

PIC16C57-HS/SO - 20MHz 8-bit OTP MCU, 3KB, 28-SOIC | Microchip
PIC16C57-HS/SO

PIC16C57-HS/SO - 20MHz 8-bit OTP MCU, 3KB, 28-SOIC | Microchip

The Microchip PIC16C57-HS/SO is an 8-bit fully-static EPROM/OTP-based CMOS microcontroller from the PIC16C5X family, operating up to 20 MHz with a 2K x 12 (3 KB) one-time-programmable program memory and 72 bytes of RAM in a 28-pin SOIC (SO) wide-body package. Its HS (High-Speed) oscillator suffix designates the use of an external crystal/oscillator in the DC–20 MHz range, distinguishing it from the RC, LP (low-power), and XT (standard) variants in the same family. The device integrates 20 general-purpose digital I/O lines, an 8-bit real-time clock/counter (TMR0) with an 8-bit prescaler, a two-level deep hardware stack, and direct/indirect/relative addressing for both data and instructions. A microcontroller (MCU) is a single-chip computer that integrates a CPU, RAM, non-volatile program memory (here, OTP EPROM), and peripherals such as timers and I/O ports. The PIC16C5X family sits at the entry-level of Microchip's 8-bit PIC architecture, optimized for cost-sensitive, deterministic, bit-manipulation-heavy embedded tasks where RISC-like instruction execution and low pin count matter more than raw throughput. Key differentiating features include 12-bit-wide instructions on an 8-bit data path for compact code density, seven or eight special-function hardware registers, a watchdog timer option, and a Power-on Reset (POR) circuit. The wide 7.5 mm body SOIC (SO) package supports surface-mount manufacturing while maintaining drop-in compatibility with the 28-pin PDIP footprint on adapter boards. Compared with the PIC16F57-I/SO Flash successor, the PIC16C57-HS/SO offers OTP rather than in-circuit reprogrammability, which lowers per-unit cost for mature, finalized firmware. Typical applications include appliance control boards, simple sensor-conditioning front-ends, LED display drivers, automotive body controllers, and hobby robotics. The wide operating voltage range (typically 3.0 V to 5.5 V) and low standby current make it suitable for battery-backed subsystems. Designers should reserve the OTP window only for fully validated firmware, since OTP parts cannot be rewritten; production programming must use a Microchip-supported device programmer such as MPLAB PM3.

PIC16C57-HS/SP

PIC16C57-HS/SP - 8-bit 20MHz OTP MCU, 3KB | Microchip

The Microchip Technology PIC16C57-HS/SP is an 8-bit CMOS RISC microcontroller in a 28-pin SPDIP (Skinny Plastic DIP) package, operating at 20 MHz with 3 KB (2K x 12) of One-Time Programmable (OTP) program memory and 72 bytes of RAM. It is part of Microchip's legacy PIC16C5x family, delivering high performance in its price class through a 12-bit wide instruction word that yields 2:1 code compression over competing 8-bit MCUs. A microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory, data RAM, and I/O peripherals. Within the broader taxonomy, PIC16C5x parts are classified as 8-bit microcontrollers -> RISC microcontrollers -> embedded controllers -> semiconductors. The PIC16C5x line uses a Harvard architecture with separate program and data buses, a two-level deep hardware stack, and direct/indirect/relative addressing modes. OTP memory is one-time programmable (cannot be erased), which is ideal for high-volume mature products and is more cost-effective than UV-erasable EPROM or Flash. Key specifications include: 20 MHz maximum clock (HS oscillator mode, hence the -HS suffix), 33 single-word instructions, 8-bit ALU, 20 source/sink I/O pins, one 8-bit real-time clock/counter (TMR0), and a watchdog timer. The wide operating voltage range of 2.5 V to 6.25 V and commercial temperature grade (0 C to +70 C) make it suitable for cost-sensitive embedded control applications. Power consumption is low at approximately 2 mA typical at 5 V / 20 MHz. Architecturally, the PIC16C5x uses a RISC instruction set with a fixed 12-bit instruction width and an 8-bit data path. All instructions execute in a single cycle except branches, which take two cycles. Two special function hardware registers (OPTION and TRIS) configure the I/O direction and prescaler, and seven or eight additional special function registers handle peripheral control and arithmetic. The device does not include interrupts, which is a defining characteristic of the PIC16C5x baseline family. Typical applications include appliance controls, simple sensor interfaces, LED driving controllers, low-cost consumer electronics, and industrial timers/counters. The PIC16C57 is also widely used as a one-time-programmable replacement for legacy 8-bit designs where board space and BOM cost are critical and Flash reprogrammability is not required. When designing with the PIC16C57-HS/SP, choose the HS oscillator mode carefully: it supports high-speed crystals/resonators up to 20 MHz but draws more current than the LP (low-power) or RC modes. Since OTP memory cannot be erased, consider emulating the design on a PIC16F5x Flash equivalent (e.g., PIC16F57) for development, then migrating to PIC16C57-HS/SP for production to minimize unit cost.

PIC16C57-HS/SS - 8-Bit 20MHz OTP MCU 2KB EPROM | Microchip
PIC16C57-HS/SS

PIC16C57-HS/SS - 8-Bit 20MHz OTP MCU 2KB EPROM | Microchip

The Microchip Technology PIC16C57-HS/SS is an 8-bit RISC EPROM/ROM-based CMOS microcontroller in the PIC16C5X family, supplied in a 28-pin SSOP package. It provides 2KB of EPROM program memory (organized as 2K x 12), 72 bytes of RAM, and operates from a single 5V supply with a maximum clock rate of 20 MHz (HS oscillator grade). An 8-bit microcontroller (MCU) is a small, single-chip computer built around an 8-bit data path, a CPU, program memory, data RAM, and a fixed set of peripheral registers. The PIC16C5X architecture uses 12-bit-wide instructions and an 8-bit-wide data path, achieving roughly 2:1 code compression compared with other 8-bit MCUs in its class, and executes most instructions in a single 200 ns instruction cycle at 20 MHz. This combination of small footprint, deterministic execution, and low cost established the PIC16C5X family as the de-facto baseline for simple embedded control in the 1990s and is still emulated today in retro-arcade and industrial designs. Key features of the PIC16C57-HS/SS include 12 I/O pins across two ports (RA0-RA3, RB0-RB7), an 8-bit real-time clock/counter (TMR0) with an 8-bit programmable prescaler, a watchdog timer, a two-level deep hardware stack, and direct/indirect/relative addressing modes for both data and instructions. Seven or eight special-function hardware registers handle all peripheral control, keeping the core die size minimal. The HS grade specifies a high-speed external crystal/ceramic resonator oscillator mode supporting up 20 MHz operation. Architecturally, the PIC16C57-HS/SS uses a fully static CMOS RISC core, meaning clock frequency can be reduced arbitrarily for power savings without losing state. The Harvard memory architecture separates program (12-bit wide EPROM) and data (8-bit wide RAM) buses, eliminating the von Neumann fetch bottleneck. On-chip EPROM allows one-time-programmable (OTP) code storage, ideal for low-to-medium volume production where mask-ROM NRE is not amortized. Typical applications include legacy industrial control, security/alarm panels, appliance controllers, automotive body electronics, simple sensor interfaces, arcade and pinball board replacement (the PIC16C57 is widely emulated in MAME), and consumer IR remote transmitters. The 28-SSOP package is suitable for hand-solder prototyping and reflow production alike. A key design consideration is that the PIC16C57 family uses a 12-bit instruction word and lacks in-circuit serial programming (ICSP) on most packages; engineering samples or production units must be programmed externally with a device programmer such as the MPLAB PM3. Designers transitioning newer code should evaluate the pin-compatible PIC16F57 (Flash-based, ICSP-capable) as a same-footprint migration path. This page synthesizes distributor pricing, drop-in same-package alternatives, and practical design notes that complement, rather than duplicate, the official Microchip datasheet.

PIC16C57-HSE/P - 8-bit OTP MCU, 3KB EPROM, 20 I/O, 28-PDIP | Microchip
PIC16C57-HSE/P

PIC16C57-HSE/P - 8-bit OTP MCU, 3KB EPROM, 20 I/O, 28-PDIP | Microchip

The Microchip Technology PIC16C57-HSE/P is an 8-bit RISC microcontroller from the PIC16C5X baseline family, featuring 3KB of one-time-programmable (OTP) EPROM program memory, 72 bytes of RAM, and 20 digital I/O pins in a 28-pin PDIP through-hole package. The "HSE" speed suffix denotes a high-speed oscillator variant operating up to 20 MHz with a 200 ns instruction cycle, and the "/P" suffix indicates the plastic DIP package supplied in tube packaging. This device runs from a 3.0V to 6.0V supply and is specified for the commercial 0C to +70C temperature range. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory, working RAM, and configurable I/O peripherals onto one silicon die. The PIC16C5X family sits at the low-cost, low-pin-count end of Microchip's PIC baseline architecture and is widely used in cost-sensitive embedded applications. Within the broader taxonomy, PIC microcontrollers belong to the RISC microcontroller category, which contrasts with CISC architectures by using a small, fixed-length instruction set that executes most instructions in a single cycle. The 12-bit-wide instruction set enables 2:1 code compression over typical 8-bit CISC MCUs, allowing more functionality in less program memory. Key features of the PIC16C57-HSE/P include a 33-instruction set, a two-level hardware stack, 8-bit timer/counter with 8-bit prescaler, watchdog timer with on-chip RC oscillator for reliable operation, power-on reset, and brown-out detection. The 20 I/O pins can be individually configured for input or output and can source/sink up to 20 mA per pin, making them capable of directly driving LEDs and small relays. The high-speed 20 MHz operation delivers 5 MIPS of throughput, suitable for simple control loops and user-interface scanning tasks. Architecturally, the PIC16C57-HSE/P uses a Harvard architecture with separate program and data buses, allowing simultaneous instruction fetch and operand access. The EPROM-based program memory enables prototyping and low-volume production, but cannot be electrically erased, so OTP programming is final. In-circuit serial programming (ICSP) is supported via RB6/RB7 pins, simplifying firmware loading on the production line. Typical applications include simple consumer appliances, remote controls, low-end toys, small appliances with keypad/LED user interfaces, sensor interface nodes, and legacy industrial controllers. The 20 I/O count and 3KB program memory comfortably handle a 4x4 keypad matrix scan, 7-segment LED multiplexing, and basic PID control loops. When designing with this device, plan the OTP programming process early: once programmed, OTP cannot be erased, so firmware bugs in production parts cannot be recovered. Use a windowed PIC16C57-JW variant for engineering development so the same die can be UV-erased and re-programmed during code iteration.

PIC16C57-HSE/SO - 8-Bit 16MHz 3KB OTP MCU 28-SOIC | Microchip

The Microchip Technology PIC16C57-HSE/SO is an 8-bit RISC microcontroller from the PIC16C5X family, featuring a 16 MHz maximum clock speed, 3 KB of One-Time-Programmable (OTP) program memory organized as 2K x 12 words, and 72 bytes of data RAM, all housed in a 28-pin Small Outline Integrated Circuit (SOIC) package. A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory, and peripherals. An 8-bit MCU like the PIC16C57 processes data 8 bits at a time and is widely used in cost-sensitive embedded applications where deterministic performance and low power are more critical than raw throughput. Within the broader semiconductor hierarchy, an MCU is a sub-category of microcontrollers, which sit under integrated circuits (ICs) and the wider power management and digital logic taxonomy. PIC16C5X devices use a Harvard architecture with separate program and data buses, enabling single-cycle instruction execution except for program branches. Key features of the PIC16C57-HSE/SO include a Harvard RISC architecture with 33 single-word instructions, a 12-bit wide instruction set providing 2:1 code compression over competing 8-bit MCUs, 20 I/O pins with individual direction control, a watchdog timer for reliable operation, and a power-on reset (POR) circuit. The device operates from a 4.5V to 5.5V supply and includes a high-speed 16 MHz external oscillator mode (the "HSE" suffix designates this 16 MHz high-speed crystal/oscillator variant). It supports operating temperatures typical of automotive and industrial grade environments. The PIC16C57's EPROM/OTP program memory architecture allows one-time programming for low-to-mid volume production, and the 16 MHz clock gives an instruction cycle of 250 ns (4 clock periods per instruction cycle). Power management features include a sleep mode that reduces quiescent current dramatically, plus a programmable code-protection scheme that prevents unauthorized memory reads. The 28-SOIC package is industry-standard and easy to hand-solder, making the part attractive for prototyping and small-batch builds. Typical applications include automotive body controllers, appliance control boards, simple sensor interfaces, low-end remote controls, LED driver controllers, and industrial timers. The PIC16C57 is also common in legacy industrial equipment and educational platforms because of its long product history and mature tool chain. When designing with the PIC16C57-HSE/SO, engineers should plan for OTP programming only once per device; for development, use a windowed (JW) package or the pin-compatible PIC16C57C flash variants. Because OTP memory cannot be erased, allocate spare program memory for late-stage bug fixes.

PIC16C57-HSE/SP - 8-Bit 16MHz OTP MCU 3KB | Microchip

The Microchip Technology PIC16C57-HSE/SP is an 8-bit EPROM/ROM-based CMOS microcontroller from the PIC16C5X family, operating at 16MHz with an external HS oscillator configuration and packaged in a 28-pin SPDIP (Skinny Plastic DIP) through-hole form factor. The HSE suffix denotes the high-speed external oscillator mode, the SP suffix denotes 28-pin SPDIP package, and the device is qualified to the automotive temperature grade. According to the Microchip product listing, the device integrates 3KB (2K x 12) of One-Time-Programmable (OTP) program memory and 72 bytes of RAM, with 20 general-purpose I/O pins split across two ports (RA and RB). An 8-bit PIC microcontroller (MCU) is a RISC-based single-chip computer that combines a CPU core, non-volatile program memory, working RAM, and programmable I/O peripherals on a single silicon die. PIC microcontrollers sit within the broader hierarchy of microcontroller -> embedded processor -> semiconductor IC. The PIC16C5X family specifically targets cost-sensitive, low-to-moderate-performance embedded applications where deterministic instruction execution, simple peripheral sets, and ROM/EPROM-based program storage provide the best price-to-performance ratio. The OTP variant allows one-time factory or in-circuit programming, which is typical for mature 8-bit designs with stable firmware. Key features include 33 single-word instructions, a 12-bit wide instruction word enabling 2:1 code compression over typical 8-bit CISC architectures, two 8-bit I/O ports, an 8-bit timer/counter (TMR0) with an 8-bit programmable prescaler, a Watchdog Timer (WDT) with on-chip RC oscillator for reliable recovery, and Power-On Reset (POR). The device supports an operating voltage range commonly cited as 3.0V to 6.25V across the PIC16C5X family, with low-power CMOS construction. Its 28-pin SPDIP package is through-hole, simplifying prototype and low-volume production assembly. Architecturally, the PIC16C57 uses a Harvard RISC core with separate program and data buses, a two-stage pipeline, and a single accumulator (W register) working model. The 16MHz maximum clock yields a 250ns instruction cycle, and the OTP memory is windowless, requiring UV erasure only for prototype parts (JW package). For production runs, OTP parts ship pre-programmed. The HSE oscillator mode allows use of high-frequency external crystals or oscillators, distinguishing it from HS (standard) and RC variants. Typical applications include automotive body controllers and appliance control, simple sensor signal conditioning, LED and relay driver sequencing, industrial timer/counter modules, low-cost consumer electronics, and legacy embedded control boards. The wide operating temperature range and OTP memory make it suitable for high-volume fixed-function products where firmware does not need field updates. When designing with this part, choose the HS oscillator mode for higher clock accuracy and select capacitors matched to the crystal load capacitance. Ensure unused I/O pins are configured as outputs to minimize power consumption and reduce noise susceptibility. For modern designs requiring in-field reprogrammability, consider migrating to the Flash-based PIC16F57 or PIC16F884 equivalents; the PIC16C57-HSE/SP is best suited for mature, frozen-firmware production runs.

PIC16C57-HSE/SS

PIC16C57-HSE/SS - 8-Bit EPROM MCU, 3KB OTP, 20MHz, 28-SSOP

The Microchip Technology PIC16C57-HSE/SS is an 8-bit EPROM/ROM-based CMOS microcontroller with 3KB of one-time-programmable (OTP) program memory, packaged in a 28-pin SSOP (Shrink Small Outline Package). It operates from a 20 MHz external clock input (HSE = High-Speed External oscillator) and targets cost-sensitive embedded control applications requiring deterministic RISC execution. A microcontroller (MCU) is a single-chip computer containing a CPU, memory (ROM/RAM), and programmable I/O peripherals on one IC. Within the embedded electronics taxonomy, the PIC16C57 sits in the 8-bit MCU class -> RISC microcontroller -> embedded controller -> semiconductor. It is fully static, employs a RISC architecture with 33 single-word/single-cycle instructions, and offers 12-bit-wide instruction words with a 4-stage pipeline architecture characteristic of the original PIC16C5X baseline family. Key features include 72 bytes of RAM, 20 I/O pins, a hardware timer/counter, watchdog timer, and a wide operating voltage range. The HSE oscillator suffix indicates the part supports an external high-speed clock source, allowing the engineer to feed a crystal/oscillator up to 20 MHz for deterministic instruction-cycle timing. The /SS suffix denotes the 28-SSOP surface-mount package with 0.209" (5.30 mm) body width, which is pin-compatible with the PIC16C55 and PIC16C56 in the same family. Typical applications include low-cost appliance controllers, LED display drivers, remote controls, automotive body electronics (non-safety), and simple sensor interfacing. The OTP program memory makes it suited to production volumes where mask-ROM economies of scale are not justified. When designing, note that the PIC16C57 is a legacy 5V device with no on-chip debug or flash reprogramming; code must be committed at production time and the part requires a UV windowed variant (JW) for code iteration. Verify OTP programming equipment compatibility (e.g., MPLAB PM3) before committing to this part.

The "HSI" suffix designates a high-speed crystal/oscillator variant rated for 20 MHz operation, while "/P" indicates the PDIP-28 plastic package. Key features include 33 single-word instructions (single-cycle except branches), a two-level hardware stack, direct/indirect/relative addressing modes, an 8-bit real-time clock/counter (TMR0) with programmable prescaler, power-on reset (POR), watchdog timer (WDT), and a programmable code-protect feature. Operating voltage spans 3.0 V to 5.5 V at industrial temperature range (-40C to +85C). All 20 I/O pins are bidirectional with individually programmable direction registers and high-current sink/source capability. Typical applications for the PIC16C57-HSI/P include embedded control boards, sensor interface modules, user-interface/keypad controllers, low-cost industrial automation nodes, and legacy system maintenance builds. Its high oscillator frequency makes it suited for applications requiring tighter timing loops than the lower-frequency RC variants (e.g., PIC16C57-RC/P, PIC16C57-LP/P) can deliver. When designing with this part, note that OTP EPROM cannot be electrically erased - firmware is finalized at programming time. For development cycles, use a windowed CERDIP (-JW) or flash-based PIC16F57 part instead. Decoupling VDD/VSS with 100 nF ceramic caps placed within 5 mm of the pins is recommended; MCLR must be pulled high through a 10 kohm resistor for normal operation.

PIC16C57-HSI/SO - 8-Bit 20MHz OTP MCU 3KB | Microchip
PIC16C57-HSI/SO

PIC16C57-HSI/SO - 8-Bit 20MHz OTP MCU 3KB | Microchip

The Microchip Technology PIC16C57-HSI/SO is an 8-bit CMOS microcontroller from the PIC® 16C family, featuring a 20MHz maximum CPU clock, 3KB (2K x 12) of One-Time-Programmable (OTP) program memory, and 72 bytes of RAM. It is housed in a 28-pin SOIC (7.50mm/0.295in width) surface-mount package with 20 I/O pins, optimized for cost-sensitive embedded control applications where deterministic performance and code density matter more than large memory footprints. A microcontroller (MCU) is a single-chip computer that integrates a CPU, RAM, non-volatile program memory, and peripheral I/O on one die. The PIC16C5X family specifically sits within the broader taxonomy of microcontrollers -> 8-bit microcontrollers -> CMOS microcontrollers -> RISC microcontrollers -> embedded controllers. Its Harvard architecture separates program and data buses, while 12-bit-wide instructions deliver roughly 2:1 code compression versus competing 8-bit CISC architectures, allowing more functionality in less program memory. Key features include a 20MHz high-speed internal oscillator variant (the HSI suffix denotes factory-programmed HS oscillator mode with internal clock options), 8-bit real-time clock/counter (TMR0), two-level deep hardware stack, and seven or eight special function hardware registers. The device supports direct, indirect, and relative addressing modes for both data and instructions, and operates from a single 5V supply over the commercial/industrial temperature range. The PIC16C57 architecture uses a fully static CMOS design, meaning the clock can be stopped without losing internal state. This makes it well suited for low-power or battery-friendly designs where the oscillator is duty-cycled. The 12-bit instruction set and 33 single-word/single-cycle instructions reduce program-memory pressure, while the two-level hardware stack constrains subroutine nesting to two levels, an important constraint for C or high-level-language users porting code. Typical applications include appliance control, sensor signal conditioning, LED drivers, simple motor control, remote keyless entry, security panels, and consumer white-goods user interfaces. The 20 I/O pins can directly drive LEDs, sink relays via transistors, and read keypad matrices, making the device a versatile general-purpose controller. When designing with this part, observe the OTP programming limitation: the device cannot be re-flashed after programming, so debug must occur on a windowed (JW) or EPROM emulator variant first. Decoupling VDD with a 0.1 microfarad ceramic capacitor placed within 5mm of the pin is essential for stable HS-oscillator operation.

It executes most instructions in a single 200ns instruction cycle when clocked from an external 20MHz high-speed oscillator source (the "HSI" speed grade). The device is built on a low-cost, fully-static CMOS architecture featuring a 12-bit-wide instruction word and an 8-bit data path, which delivers approximately 2:1 code compression over competing 8-bit microcontrollers in the same price class. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory, working RAM, and peripheral interfaces such as timers, I/O ports, and interrupt controllers into one package. The PIC16C5X family occupies the entry-level, cost-sensitive tier of the broader 8-bit microcontroller category, sitting below PIC16 enhanced mid-range parts and PIC18 high-performance 8-bit families in the Microchip hierarchy. PIC microcontrollers are widely used as the "brain" of embedded systems that require deterministic real-time response, low power consumption, and reprogrammability during prototyping. Key features of the PIC16C57-HSI/SP include an 8-bit real-time clock/counter (TMR0) with an 8-bit programmable prescaler, a two-level deep hardware stack for subroutine nesting, and three addressing modes: direct, indirect, and relative. The device offers seven or eight special-function hardware registers, an internal reset circuit, and a watchdog timer option that can be enabled via configuration bits. Power consumption is low due to CMOS technology, with multiple sleep/idle modes for battery-powered designs. I/O pins can source or sink up to 25mA per pin, allowing direct drive of LEDs and small relays. Typical applications span consumer electronics, appliance control, automotive subsystems, industrial sensor interfaces, and educational/development platforms. The 20 I/O lines support keypad scanning, LED multiplexing, LCD bias generation, and serial communication via bit-banged protocols (UART, SPI, I2C implemented in software). The 28-pin SPDIP package makes the part well suited for hand-soldered prototypes, breadboards, and low-volume production runs where through-hole assembly is preferred. When designing with the PIC16C57-HSI/SP, note that the part is OTP (one-time-programmable) and does not support in-circuit reprogramming. The "HSI" suffix denotes a high-speed crystal/oscillator mode with a 20MHz maximum frequency, distinct from "RC" (resistor-capacitor timing) and "LP" (low-power crystal) oscillator variants. Choose the HSI version when instruction throughput is critical; choose RC or LP when cost, board space, or power consumption is the priority.

The device supports a four-clock-per-instruction cycle and provides 33 single-word instructions. The 20 I/O pins are bidirectional with individually programmable direction registers, and each can source/sink sufficient current to directly drive LEDs in many applications, simplifying the external bill of materials. Technically, the PIC16C57 uses a Harvard architecture with separate program and data buses, enabling simultaneous instruction fetch and data access. Power consumption in the LP variant is optimized for battery-friendly designs, and the wide 2.5 V to 6.25 V supply range tolerates unregulated rails. The PIC16C57 is supported by MPLAB X IDE and the original MPLAB PM3 programmer for both PC-hosted and stand-alone programming flows. Typical applications for the PIC16C57-LP/P include appliance controllers, low-end remote controls, simple sensor interfaces, LED drivers, hobby projects, and educational embedded platforms where a small, reliable 8-bit core is sufficient. Industrial uses cover timer modules, fan controllers, and basic HMI panels. When designing with the PIC16C57-LP/P, verify the oscillator mode (LP, XT, RC, HS) by suffix - the LP suffix specifies the low-power oscillator mode intended for 32.768 kHz watch crystals and very low standby current. Engineers migrating to a flash-based core should consider the PIC16F57 family for in-circuit reprogrammability on the same 28-pin footprint.

The "LPE" suffix indicates the low-power, EPROM, extended-temperature (-40 °C to +125 °C) variant, while the "/P" suffix denotes the PDIP package. Operating from 2.5 V to 6.0 V, the part targets cost-sensitive, high-volume embedded control. What is an OTP microcontroller? An OTP (One-Time-Programmable) microcontroller is a non-volatile programmable device whose on-chip program memory can be written exactly once using an EPROM cell, after which the code is permanent and cannot be erased. OTP MCUs sit in the broader taxonomy: microcontroller -> embedded controller -> semiconductor device. Compared to Flash or EEPROM MCUs, OTP parts offer lower per-unit cost, smaller die area, and higher production security (no field reprogrammability), at the expense of re-programmability during prototyping. Engineers typically prototype with windowed or Flash parts and migrate to OTP for volume production. The PIC16C57-LPE/P employs a RISC architecture with only 33 single-word/single-cycle instructions, a 12-bit instruction word, and a 2:1 code compression ratio versus competitors in its class. Two 8-bit timer/counters, a watchdog timer with its own on-chip RC oscillator, and a programmable code-protection bit are integrated. The device features fully static operation, allowing the clock to be stopped without loss of register data. Typical applications include industrial control, automotive subsystems, white-goods and appliance controls, simple sensor interfacing, consumer electronics user interfaces, and low-cost remote transmitters. The wide 2.5 V-6.0 V supply range accommodates both 3.3 V and 5 V rails commonly found in legacy industrial designs. When designing with this device, note that OTP memory cannot be re-programmed: code must be fully validated before committing to production. For development cycles requiring repeated programming, consider the Flash-based PIC16F57 equivalent. The 28-PDIP package is through-hole only and is preferred for prototype, hobby, and legacy-replacement use cases where socketed or hand-solderable parts simplify rework.

It operates at up to 40 kHz (LP oscillator, low-power) on a 5V supply and provides 20 digital I/O pins for direct interfacing with peripherals, switches, and indicators. The /P suffix denotes the through-hole PDIP-28 (0.600 inch, 15.24 mm) package, while the LPI suffix indicates the low-power (LP) oscillator variant in industrial temperature grade. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory, data RAM, and I/O peripherals on one silicon die. The PIC16C5X family uses a 12-bit-wide instruction word with an 8-bit data path - this RISC architecture executes most instructions in a single clock cycle, enabling deterministic timing for control applications. The PIC16C57 belongs to the baseline PIC architecture, the original Microchip core that pre-dates the PIC16F mid-range family and is purpose-built for low-cost, high-volume embedded control tasks where code is committed once at production. Key features of the PIC16C57-LPI/P include seven or eight special function hardware registers, a two-level deep hardware stack, direct, indirect and relative addressing modes for both data and instructions, and an 8-bit real-time clock/counter (TMR0) with an 8-bit programmable prescaler. The device supports internal and external interrupt sources, a watchdog timer for code-flow safety, and a power-on reset (POR) block. Power-saving SLEEP mode is entered via software and wakes on interrupt or watchdog timeout, which is critical for battery-powered or energy-harvesting nodes. The PIC16C57 is fabricated in a CMOS process that yields fully static operation across the full supply range, allowing the clock to be stopped without losing register state. The 12-bit instruction set (33 single-word instructions) is optimized for bit-level manipulation and compact code density, while the 20 I/O pins each have independent direction control and can source/sink sufficient current to drive LEDs directly without external buffers. The integrated watchdog and POR reduce external component count, lowering BOM cost in production designs. Typical applications include appliance control (washers, microwave ovens, coffee makers), HVAC thermostats and zone controllers, automotive interior modules (non-safety), security-system keypads, remote transmitters, low-end consumer toys, metering and data-logger front-ends, and any high-volume, cost-sensitive embedded product where OTP memory is acceptable. The industrial temperature grade (-40C to +85C) makes it suitable for outdoor enclosures and uncontrolled environments. When designing with the PIC16C57-LPI/P, note that the LP oscillator requires an external crystal or resonator, and decoupling capacitors must be placed close to VDD/VSS pins to ensure stable operation. The 2-level hardware stack constrains call depth; subroutines must be kept shallow or inlined to avoid stack overflow. Designers familiar with mid-range PIC16F parts should verify interrupt and register-mapping differences against the baseline PIC16C5X reference manual.

The architecture's seven or eight special-function hardware registers, combined with direct, indirect, and relative addressing modes, deliver predictable, deterministic response times suitable for real-time control. OTP EPROM program memory allows fast prototyping and small-to-medium volume production without mask charges, making it ideal for designs transitioning from PIC16C5x prototypes to higher-density PICmicro derivatives. Typical applications include appliance controls, simple sensor interfaces, low-end automotive body electronics, LED driver controllers, battery chargers, and remote-control transmitters. The 20 I/O pins support direct LED drive and matrix keypad scanning, while the TMR0 peripheral handles pulse-width measurement and timing events without CPU intervention. The integrated RC oscillator further reduces external component count, saving PCB area and BOM cost. When designing with this part, engineers should note that the two-level hardware stack limits subroutine nesting depth; complex interrupt-driven or deeply-nested code must be flattened. Programming requires an EPROM programmer compatible with the PIC16C5x family (e.g., MPLAB PM3), and OTP windows cannot be erased. This page synthesizes real-time distributor pricing, parametric alternatives, and engineering design notes not aggregated on any single manufacturer or distributor page, helping procurement engineers source a long-lifecycle baseline MCU.

PIC16C57-RC/SP

PIC16C57-RC/SP - 8-bit EPROM MCU, 4MHz, 28-SPDIP | Microchip

The Microchip Technology PIC16C57-RC/SP is an 8-bit EPROM/ROM-based CMOS microcontroller from the PIC16C5X family, delivering up to 4 MHz CPU clock speed in a 28-pin SPDIP package. It integrates 2 KB of one-time-programmable EPROM program memory (2048 x 12 words) and 72 bytes of on-chip data RAM, with 20 digital I/O pins grouped into three ports (RA, RB, RC). The device operates from 3.0 V to 6.25 V (typically 3.3 V or 5 V) and consumes only a few milliamps active, making it suited to low-cost embedded control. An EPROM/ROM-based 8-bit microcontroller is a single-chip computer that integrates a CPU, non-volatile program memory (here, EPROM), working RAM, and I/O peripherals. It belongs to the broader hierarchy: microcontroller -> embedded MCU -> semiconductor IC. The PIC16C5X architecture uses a RISC-style PIC16 CPU core with 12-bit-wide instructions and an 8-bit data path, achieving roughly 2:1 code compression over typical 8-bit CISC competitors and roughly 100 ns instruction execution at 4 MHz. A two-level deep hardware stack supports subroutine nesting, and direct, indirect, and relative addressing modes cover both data and instruction fetches. Key features of the PIC16C57-RC/SP include an 8-bit real-time clock/counter (TMR0) with programmable prescaler, integrated Watchdog Timer (WDT) for safe recovery from code lockup, Power-On Reset (POR) and Brown-Out Reset (BOR) for reliable startup across noisy supplies, and a low-power SLEEP state that minimizes quiescent draw. Peripherals include two timers (TMR0 + WDT prescaler block), 20 GPIO lines, and an EPROM program memory that allows code development before committing to a ROM mask. The device is windowed/OTP-programmable via Microchip's PRO MATE II or MPLAB PM3 programmers. Technically, the PIC16C5X core uses a single accumulator (W register) and a small register file of seven or eight special-function hardware registers. The Harvard-style separate program and data buses mean program fetches and data accesses do not contend, and the 12-bit instruction word keeps code density high. With only 33 single-word instructions, the assembly language is intentionally simple, easing porting across the PIC16C5X sub-family. The architecture is well documented in Microchip's PICmicro Mid-Range Reference Manual. Typical applications for the PIC16C57-RC/SP include low-cost consumer appliances, simple sensor signal conditioning, hobby and education projects, replacement of discrete logic in glue-controller roles, and legacy industrial controls where a proven, mature MCU is preferred over newer flash parts. The wide 3.0-6.25 V supply range also supports battery-powered and 5 V industrial backplanes. When designing with the PIC16C57-RC/SP, allocate I/O carefully because only 20 of the 28 package pins are usable as general-purpose I/O; the remaining pins are VDD, VSS, OSC1/OSC2, and MCLR. Use RC oscillator mode (denoted by "-RC") to minimize BOM cost versus a crystal, and place decoupling capacitors (100 nF ceramic) within a few millimeters of VDD/VSS. Confirm programmer socket compatibility with PRO MATE II or MPLAB PM3 and source OTP-windowed units only when field re-programmability is required.

PIC16C57-RC/SS - 8-Bit EPROM MCU, 3KB OTP, 4MHz, SSOP-28
PIC16C57-RC/SS

PIC16C57-RC/SS - 8-Bit EPROM MCU, 3KB OTP, 4MHz, SSOP-28

The Microchip Technology PIC16C57-RC/SS is an 8-bit EPROM/ROM-based CMOS microcontroller from the PIC16C5X family, delivering 3KB of one-time-programmable (OTP) program memory in a 28-pin SSOP (5.30 mm / 0.209 in width) surface-mount package. It operates from 3.0V to 6.25V with the 'RC' speed grade indicating a 4 MHz oscillator option, and it uses a 12-bit wide instruction word with an 8-bit data path for 2:1 code compression relative to competing 8-bit MCUs in its class. The device is fully static, includes 72 bytes of RAM, and is built around a RISC architecture with only 33 single-word/single-cycle instructions. What is an 8-bit OTP microcontroller? It is a small, low-cost CMOS processor with a Harvard architecture in which the program is stored in one-time-programmable EPROM (or mask ROM) and the data in a small on-chip RAM. OTP microcontrollers belong to the broader hierarchy of microcontrollers (MCU) -> embedded controllers -> semiconductors. They are widely deployed in cost-sensitive, high-volume, single-purpose appliances where the program is finalized in production and never needs in-field firmware updates. The PIC16C5X family specifically targets applications that need deterministic timing, low power consumption, and a tiny footprint without the overhead of flash-based MCUs. Key features of the PIC16C57-RC/SS include a two-level deep hardware stack, direct/indirect/relative addressing modes for both data and instructions, an 8-bit real-time clock/counter (TMR0) with 8-bit programmable prescaler, power-on reset, watchdog timer with its own on-chip RC oscillator, and a power-saving SLEEP mode. The 20 I/O pins are bidirectional and individually programmable. The 4 MHz oscillator input supports RC, XT, HS, and LP modes within the family, though this RC variant is characterized for resistor-capacitor oscillator operation up to 4 MHz. The PIC16C57 is fabricated on Microchip's CMOS process with low-power design techniques that yield typical active current of a few mA and standby (SLEEP) currents under 10 µA depending on clock configuration. Its Harvard memory architecture separates program (12-bit wide) and data (8-bit wide) buses, eliminating instruction fetch bottlenecks. Combined with single-cycle instruction execution at 4 MHz (250 ns instruction cycle), the device delivers roughly 4 MIPS of throughput - more than sufficient for motor control, user-interface scanning, and simple communication tasks. Typical applications include appliance controls (washing machines, microwave ovens, rice cookers), consumer remote controls, battery chargers, smart sensors, HVAC thermostat control boards, and industrial timer/sequencer modules. Its deterministic execution and small footprint make it a long-time industry workhorse for cost-driven, high-volume embedded designs. When designing with the PIC16C57-RC/SS, ensure your oscillator circuit follows Microchip's RC oscillator guidelines (R between 5 kΩ and 100 kΩ, C above 20 pF) for stable operation. Use the SLEEP mode aggressively in battery-powered applications; combined with the watchdog timer you can achieve average current well below 100 µA. Since the device is OTP (not flash), program verification must be done before final code commit. This page synthesizes distributor pricing, drop-in alternative cross-references, and practical design notes that complement the manufacturer datasheet for engineers evaluating the PIC16C57-RC/SS for new or legacy designs.

PIC16C57-RCE/SO - 8-Bit 4MHz OTP MCU 3KB EPROM | Microchip
PIC16C57-RCE/SO

PIC16C57-RCE/SO - 8-Bit 4MHz OTP MCU 3KB EPROM | Microchip

The Microchip Technology PIC16C57-RCE/SO is a member of the PIC16C5X family of low-cost, high-performance, 8-bit fully static, EPROM/ROM-based CMOS microcontrollers delivering 4 MHz CPU performance, 3 KB (2K x 12) of One-Time-Programmable (OTP) program memory, 72 bytes of RAM, and 20 I/O pins in a 28-pin SOIC (0.295"/7.50 mm width) package. The 'RCE' suffix denotes the RC oscillator variant with extended (-40C to +125C) operating temperature range, and the SOIC package variant is supplied in tube packaging. What is an OTP microcontroller? An OTP (One-Time-Programmable) microcontroller is a type of embedded processor whose program memory can be written only once after manufacture, after which the program becomes permanent. OTP parts sit in the broader hierarchy of microcontroller -> embedded processor -> semiconductor device -> integrated circuit. They are favored over flash-based MCUs for cost-sensitive, high-volume applications where firmware is finalized before production and field re-programmability is not required. Key features of the PIC16C57-RCE/SO include a RISC instruction set with only 33 single-word/single-cycle instructions, 12-bit-wide opcodes delivering 2:1 code compression over competing 8-bit architectures, two 8-bit timer/counters, a watchdog timer with on-chip RC oscillator, power-on reset, and a 4 MHz internal/external clock domain. The wide operating voltage range of 3.0 V to 6.0 V and ultra-low power consumption make it well-suited for both battery-powered and line-powered systems. The PIC16C57 employs a Harvard-class pipelined architecture, where program and data buses are physically separate, allowing instruction fetch and execute to overlap each machine cycle. This is the architectural foundation behind the family's advertised 'order of magnitude higher performance than competitors at the same price' claim, since a 4 MHz clock effectively delivers 4 MIPS of throughput. The 20 digital I/O pins are multiplexed with peripheral functions and are capable of directly sourcing/sinking 25 mA per pin for LED and relay drive. Typical applications span industrial control, automotive subsystems, consumer appliances, security panels, and any cost-driven embedded product. The 'RCE' temperature grade (-40C to +125C) and SOIC surface-mount form factor specifically target industrial-grade SMT assemblies that must withstand wave-solder reflow and operate across extended thermal ranges. The PIC16C5X family remains one of the most widely cloned and second-sourced 8-bit MCU architectures in the industry. When designing with this part, remember that OTP memory cannot be erased or rewritten; prototype firmware must be fully debugged before committing to a PIC16C57-RCE/SO production run. Engineers evaluating reprogrammable alternatives should consider the PIC16F57 (flash-based, same pinout) instead. For power-budget calculations, the device typically draws <2 mA active at 4 MHz/5 V and <10 uA in sleep mode. This page synthesizes distributor pricing, parametric specifications, drop-in alternatives within the PIC16C5X family, and practical design notes for OTP MCU selection not found in the manufacturer datasheet alone.
