PIC16C57-10/P 개요
An 8-bit microcontroller (MCU) is a single-chip processor that integrates a CPU, program memory, data memory, and peripheral I/O onto one die. Within the broader hierarchy, the PIC16C57 belongs to the category of 8-bit microcontrollers -> microcontrollers -> microprocessors -> digital ICs -> semiconductors. The 'C' in PIC16C57 designates the OTP/EPROM program memory variant (vs. 'F' for Flash and 'HV' for high-voltage variants), making it one-time field-programmable using a device programmer such as the MPLAB PM3.
Key features of the PIC16C57-10/P include a 12-bit wide instruction set with 8-bit data path, two-level deep hardware stack, direct/indirect/relative addressing modes, and a single 8-bit real-time counter/timer (TMR0). It supports seven or eight special-function hardware registers (SFRs) depending on configuration, and provides a watchdog timer for reliable standalone operation. The CMOS process delivers low quiescent current suitable for battery-powered or always-on applications.
The PIC16C57-10 architecture is a classic Harvard design with separate program and data buses, enabling simultaneous instruction fetch and data access. The RISC core executes most instructions in a single cycle, delivering approximately 5 MIPS at 10MHz - an order of magnitude above contemporaries in the same price class. The 2:1 code compression relative to other 8-bit MCUs reduces program memory pressure for the 3KB EPROM.
Typical applications include industrial control logic, appliance controllers, simple sensor interfaces, automotive body electronics (non-safety), low-end consumer devices, and legacy embedded systems. Designers often choose the PIC16C57-10/P for cost-sensitive applications where the OTP memory model is acceptable and the 20 I/O count fits the system needs.
When designing with this device, note that OTP memory cannot be reprogrammed in-circuit - a programmed device cannot be erased, only replaced. For prototype or iterative-development workflows, a Flash variant (PIC16F57) is recommended. Always include decoupling capacitors within 5mm of VDD/VSS pins.

일반적인 애플리케이션
PIC16C57-10/P 적합 용도: 6 애플리케이션s: Industrial Control Logic, Appliance Control Boards, Simple Sensor Interface Nodes, Automotive Body Electronics (Non-Safety), Low-End Consumer Electronics, Legacy Embedded System Maintenance.
Industrial Control Logic
The PIC16C57-10/P fits industrial control logic designs where deterministic 8-bit RISC performance and low cost outweigh in-field reprogrammability. Its 10MHz core delivers approximately 5 MIPS, sufficient for sequential state machines, relay drivers, and timing controllers in PLCs and machine automation. The 20 I/O pins handle multi-zone sensor polling, while the on-chip watchdog timer recovers from EMI-induced lockups in factory-floor environments. Operating from 3.0V to 5.5V, the MCU accepts 24V industrial rails after a regulator. The 28-pin PDIP package remains a strong fit for control cabinets where through-hole serviceability matters more than board density.

Appliance Control Boards
Appliance controllers in washing machines, microwave ovens, dishwashers, and HVAC units are a classic application for the PIC16C57-10/P. Its 3KB OTP EPROM holds keypad scan routines, motor-control state machines, and timer logic for white-goods products. The 25 mA per-pin drive capability directly switches indicator LEDs, small solenoid valves, and buzzer transducers without external drivers. CMOS low quiescent current keeps standby consumption compliant with energy-efficiency regulations. The 28-pin PDIP package is straightforward for wave-soldered production boards common in appliance manufacturing. Designers value the deterministic interrupt response for safety-critical timing such as door-lock interlocks and over-temperature shutdowns.

Simple Sensor Interface Nodes
Low-cost sensor-interface nodes for HVAC, building automation, and remote telemetry benefit from the PIC16C57-10/P's combination of 20 I/O, 3KB EPROM, and CMOS low power. The MCU reads multiple digital sensors (PIR motion, magnetic reed switches, thermistor networks via ADC-free voltage dividers) and drives relay or transistor output stages. With a 10MHz clock, the part completes sensor sweeps and debounce routines well under 100 ms, ensuring responsive event handling. The OTP memory model suits sealed-field deployments where firmware tampering is undesirable. The 3.0 V to 5.5 V supply range accommodates both battery stacks and rectified mains adapters with a simple zener regulator.

Automotive Body Electronics (Non-Safety)
Non-safety automotive body electronics - interior lighting controllers, mirror adjusters, accessory timers, and door-module logic - historically used the PIC16C57-10/P. The 28-pin PDIP footprint and 20 I/O handle multiple lamp drivers and switch inputs. For new designs, however, the commercial temperature grade (0C to +70C) is insufficient; automotive applications require the PIC16C57-10I/P (industrial) or AEC-Q100-qualified successors. Designers should note that this part is NRND and not recommended for new automotive designs, where modern PIC16F193x or dsPIC33 families provide qualified alternatives with CAN/LIN peripherals.
추천
Low-End Consumer Electronics
Cost-sensitive consumer products such as remote controls, toy electronics, novelty gadgets, and entry-level timers are ideal applications for the PIC16C57-10/P. Its 3KB OTP EPROM is sufficient for IR protocol encoding, button matrix scanning, LED chase patterns, and simple melody generators. The 20 I/O directly drive segment displays or RGB LEDs, while the CMOS core draws under 2 mA active, extending battery life in portable devices. OTP memory prevents firmware cloning - a plus for protecting proprietary protocols. For high-volume consumer goods where every penny matters, the PIC16C57-10/P remains a workhorse part despite its NRND status on Microchip's roadmap.
추천
Legacy Embedded System Maintenance
Many legacy industrial, scientific, and medical devices still operate with PIC16C57-10/P controllers and require periodic replacement or refurbishment. The 28-pin PDIP through-hole form factor supports socketed boards where individual MCU swaps are feasible without desoldering. Stockpile management for NRND parts is a real concern; this part is currently available at Heisener (33,600 pieces as of 2026-09-17) but availability will diminish. For maintenance, the PIC16C57-10I/P and PIC16F57-I/P serve as pin-compatible replacements that accept the same HEX firmware after minor configuration-bit adjustments documented in Microchip migration guides.

설계 노트
Place a 100 nF ceramic decoupling capacitor within 5 mm of each VDD pin (pins 25 and 26) and a bulk 10 uF tantalum or aluminum electrolytic capacitor on the supply rail. The PIC16C57-10/P operates from 3.0 V to 5.5 V; for noisy industrial environments, add a ferrite bead in series with VDD and a TVS diode (e.g., SMAJ5.0A) for transient protection. Estimated: total quiescent current is approximately 1.5 mA active at 5V/10MHz; deep sleep equivalent is below 1 uA when applicable.
Route the oscillator traces (OSC1/OSC2) symmetrically and keep them short - under 10 mm if possible - to minimize EMI and stray capacitance. Place the crystal or resonator as close to the MCU as the layout allows, with a guard ground trace on each side. Avoid routing signal traces under the crystal. For HS (high-speed) oscillator mode above 4 MHz, a parallel resistor (100 k ohm to 1 M ohm) across the crystal may be required per Microchip AN588 to stabilize oscillation start-up.
OTP EPROM memory cannot be erased once programmed - any firmware bug in production is a write-off. Mitigate by programming known-good golden units first, validating with a socketed prototype (use the 28-pin PDIP package to enable IC swap), and maintaining firmware revision control. Also note that the two-level hardware stack limits call nesting to two deep - any function calling a function will corrupt the return address. Restructure code iteratively rather than recursively.
The MCLR/VPP pin (pin 4) should be pulled up to VDD through a 10 k ohm resistor to prevent spurious resets. Add a 100 nF capacitor from MCLR to VSS to filter noise spikes; values above 1 uF slow the VPP rise time during programming and may cause programming failures. Keep the MCLR trace short and away from high-frequency switching signals. For in-system programming headers, isolate the VPP line from the rest of the circuit to avoid contention.
Each PIC16C57-10/P I/O pin can source or sink up to 25 mA, but the total port current is limited (typically 100 mA per port and 200 mA for VDD). When driving multiple LEDs or relays, distribute the load across PORT A, B, and C to avoid exceeding aggregate limits. Use a logic-level MOSFET (e.g., 2N7002) to buffer high-current loads rather than driving them directly from the MCU pin to extend reliability.
규정 준수 정보
