PIC16C57-HSE/SO 概要

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.

This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone, providing an engineering-focused view beyond what the datasheet or distributor catalog offers.

主な用途

PIC16C57-HSE/SO の用途: 7 件s: Automotive Body Controllers, Appliance Control Boards, LED Display and Lighting Controllers, Industrial Timers and Counters, Remote Controls and RF Encoders, Educational Microcontroller Platforms, Sensor Interface and Signal Conditioning.

🚗

Automotive Body Controllers

The PIC16C57-HSE/SO is well suited for automotive body controller modules including seat controllers, mirror adjusters, and lighting drivers, where its 16 MHz instruction throughput (250 ns cycle) provides sufficient bandwidth for timed PWM control and its automotive temperature grade supports under-hood and cabin thermal environments. The device's 20 I/O pins accommodate the multi-channel input and output requirements typical of body electronics, while the 3 KB OTP program memory is adequate for state-machine-style control firmware. Engineers benefit from the PIC16C57's mature tool chain (MPLAB, MP3 programmer) and long-term automotive supply. A key consideration is OTP one-time-programming, which means firmware must be fully validated before production programming. Compared with PIC16F57 flash variants, the PIC16C57-HSE/SO is lower cost but lacks field reprogrammability.

🏭

Appliance Control Boards

In washing machines, dishwashers, microwave ovens, and small kitchen appliances, the PIC16C57-HSE/SO manages motor timing, user-interface key scanning, sensor polling, and indicator LED multiplexing. Its 16 MHz clock enables the deterministic interrupt response required for triac-fired AC load control, while its 72 bytes RAM supports modest state variables and user-interface buffers. The OTP memory architecture suits high-volume appliance production where firmware is locked once the design is qualified. Compared with more modern PIC16F1xxx families, the PIC16C57-HSE/SO offers lower unit cost and a smaller code footprint due to its compressed 12-bit instruction set, making it attractive for cost-sensitive white goods.

💡

LED Display and Lighting Controllers

The PIC16C57-HSE/SO drives LED matrices, channel-letter signage, decorative lighting, and signage dimmers by leveraging its 16 MHz instruction rate to refresh multi-channel PWM at flicker-free frequencies above 100 Hz. With 20 I/O pins, the part can directly drive 5 to 10 PWM channels without external mux ICs, and its watchdog timer adds robustness against software lockups in unattended lighting installations. The extended temperature grade (HSE suffix) supports outdoor enclosures. For new designs, engineers should evaluate the PIC16F57 for flash flexibility, but the PIC16C57-HSE/SO remains a strong choice when firmware is finalized and cost per node is paramount in large lighting installations.

🏭

Industrial Timers and Counters

Factory-floor timers, event counters, conveyor pacing modules, and process-interval relays deploy the PIC16C57-HSE/SO as a deterministic control element thanks to its predictable 250 ns instruction cycle and integrated watchdog timer. The 3 KB OTP memory holds lookup tables for timing profiles, while 72 bytes of RAM track cycle counts and I/O states. Industrial installations value the PIC16C57's automotive-grade temperature range and long-term Microchip product support. Compared with PLC subsystems, a discrete PIC16C57-based timer delivers lower cost and simpler field service.

📱

Remote Controls and RF Encoders

Low-end RF remote controls for garage doors, ceiling fans, motorized shades, and industrial crane pendants use the PIC16C57-HSE/SO to encode button presses into fixed-format RF or IR streams. Its 16 MHz clock drives tight bit timing for protocols like EV1527 or PT2262, and the 3 KB OTP memory stores multiple device IDs and button maps. The 20 I/O pins scan 4x5 matrix keypads comfortably. Compared with dedicated encoder ICs, the PIC16C57-HSE/SO allows custom protocols and on-the-fly timing tweaks through firmware changes during development.

🖥️

Educational Microcontroller Platforms

Universities and technical colleges adopt the PIC16C57-HSE/SO in microcontroller courses and labs because of its simple 33-instruction RISC architecture, well-documented instruction set, and affordable SOIC package for breadboard-friendly breakout boards. Students learn Harvard architecture fundamentals, OTP memory programming with the MPLAB PM3 programmer, and assembly or C firmware development without the complexity of modern peripherals. The 16 MHz clock gives headroom for instruction-cycle timing labs. Compared with newer Curiosity or Arduino boards, the PIC16C57-HSE/SO teaches register-level programming that builds strong embedded foundations.

🧩

Sensor Interface and Signal Conditioning

Simple sensor-interface modules for temperature, humidity, or contact-closure inputs use the PIC16C57-HSE/SO as a low-cost ADC-free signal conditioner, debouncer, and protocol converter. While the device lacks integrated ADCs, its 16 MHz clock and 20 I/O pins can implement sigma-delta conversion via on-chip comparators or external ADC ICs. The 3 KB OTP memory holds calibration tables, and the extended temperature grade ensures outdoor sensor-housing reliability. Compared with PIC16F1xxx MCUs that include integrated ADC, the PIC16C57-HSE/SO suits cost-optimized designs where an external ADC is already specified.

It uses a 12-bit instruction word and Harvard architecture with 33 instructions, and the "HSE" suffix denotes 16 MHz high-speed oscillator with extended (automotive) temperature grade. These parameters collectively define its use in cost-sensitive 8-bit embedded applications.
Is the PIC16C57-HSE/SO pin-compatible with PIC16C55 and PIC16C56?
Yes, the PIC16C57-HSE/SO shares the same 28-SOIC pinout as the PIC16C55 and PIC16C56 within the PIC16C5X family. According to the Microchip 28-pin PICmicro pin and code compatibility chart (document 00148J2), all three parts share identical power, ground, oscillator, reset, and most I/O pin assignments, allowing engineers to migrate designs across the family with minimal PCB changes.
What are typical applications for PIC16C57-HSE/SO?
The PIC16C57-HSE/SO is typically deployed in automotive body controllers, appliance control boards, low-end remote controls, LED driver controllers, simple sensor interfaces, industrial timers, and educational microcontroller platforms. Its 16 MHz clock and OTP memory suit mid-volume production where code is finalized before programming, and its 20 I/O pins provide sufficient connectivity for small peripheral clusters.

The PIC16C57 family remains in active production as of 2026-09-17, with inventory confirmed at multiple authorized distributors including DigiKey and Heisener. However, Microchip has been migrating customers toward the PIC16C57C (flash) and PIC16F57 family for new designs, as the OTP architecture limits field upgrades. Engineers designing new products should evaluate flash-based equivalents.
What is the difference between PIC16C57 and PIC16F57?
The PIC16C57 uses OTP EPROM program memory and runs from 4.5V to 5.5V, while the PIC16F57 uses Flash memory and supports a wider 2.0V to 5.5V supply range with reprogrammability. Both share the same 28-pin DIP and 28-SOIC packages and the same PIC16C5X instruction set, making the PIC16F57 a logical migration path for new designs where in-field firmware updates are needed.

主な差別化要因

  • Extended automotive temperature grade in same 28-SOIC footprint (vs PIC16C57-HS/SO)
  • Highest 16 MHz oscillator speed in the OTP PIC16C5X family (vs PIC16C57-LPE/SO)
  • OTP memory with mature tool chain versus flash alternatives (vs PIC16C57C-20/SO)

設計ノート

The PIC16C57-HSE/SO requires a stable 4.5V to 5.5V supply with a 100 nF ceramic decoupling capacitor placed within 5 mm of the VDD pin. For battery-backed or sleep-mode designs, VDD rise time must satisfy the power-on reset (POR) specification of the device to guarantee a clean reset. Adding a bulk 10 uF tantalum capacitor near the regulator output suppresses voltage transients when motors or relays share the supply.

The "HSE" suffix designates the high-speed 16 MHz external oscillator mode. Use a fundamental-mode crystal or ceramic resonator with two 15-33 pF load capacitors sized to the crystal manufacturer's CL specification. For cost-sensitive designs, a 16 MHz external clock oscillator module can replace the crystal. Stray capacitance on OSC1/OSC2 traces should be minimized and routed away from high-noise signals to avoid clock jitter.

OTP memory cannot be erased or rewritten after programming - any firmware bug in production locks the device permanently. Always validate firmware using a JW (windowed) package or a flash-based PIC16F57 prototype before committing to OTP programming. The MCLR pin must be tied to VDD through a 10 kohm pull-up resistor and, in noisy environments, decoupled with a 100 nF capacitor to VSS. Do not leave I/O pins floating; unused pins must be configured as outputs to minimize supply current.
