PIC16C57-HSE/SS 개요
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.

일반적인 애플리케이션
PIC16C57-HSE/SS 적합 용도: 7 애플리케이션s: Low-Cost Appliance Control, LED Display and Sign Drivers, Remote Control Transmitters, Automotive Body Electronics (Non-Safety), Simple Sensor Interface Modules, Industrial Timer and Counter Modules, Educational and Hobbyist Projects.
Low-Cost Appliance Control
The PIC16C57-HSE/SS is well suited to low-cost appliance controllers such as coffee makers, blenders, and microwave user-interface boards where the 3 KB OTP memory holds menu state machines and timing routines. The 20 MHz clock supports real-time PWM for motor speed control and tone generation for beepers, while 20 mA-capable I/O pins drive LED indicators and relay coils directly. The 28-SSOP package fits the compact PCB footprints typical of consumer appliances, and OTP programming avoids mask-ROM NRE charges for moderate production volumes. The lack of in-circuit debug is acceptable since appliance firmware is finalized during development. Compared to modern Cortex-M0 alternatives, the PIC16C57 still wins on per-unit cost at 5V operating voltages.

LED Display and Sign Drivers
The PIC16C57-HSE/SS drives multiplexed LED matrices and 7-segment displays using its 20 I/O pins each capable of 25 mA source/sink. At 20 MHz, the instruction rate of 5 MIPS easily refreshes 8-digit displays at 100 Hz with software PWM dimming, eliminating the need for an external LED driver IC. The 3 KB OTP holds charlieplexing tables and font data for alphanumeric panels, while the watchdog timer guards against display lockup in unattended signage. The 28-SSOP package's small 5.30 mm body width fits behind compact display modules. Compared to dedicated LED driver chips, the PIC16C57 provides flexibility to update protocols and patterns without hardware changes.
추천
Remote Control Transmitters
The PIC16C57-HSE/SS encodes IR remote control protocols (RC5, NEC, Sony SIRC) for TV, set-top box, and audio equipment handsets, leveraging its 20 MHz clock for accurate carrier frequency generation (typically 38 kHz or 40 kHz). The 33-instruction RISC core executes protocol encoders in well under 1 KB of the 3 KB OTP, leaving room for custom command sets. The 20 I/O pins accommodate matrix-scanned keypads up to 4x5 plus indicator LEDs without external logic. OTP memory prevents accidental field reprogramming that could change the protocol unintentionally. The 28-SSOP low-profile package fits inside slim remote-control enclosures with battery contacts on the underside.
추천
Automotive Body Electronics (Non-Safety)
The PIC16C57-HSE/SS is appropriate for non-safety automotive body electronics such as interior lighting controllers, seat position memory, and accessory timers where AEC-Q100 qualification is not mandated. The 20 MHz clock handles CAN bus bit-banging or LIN protocol framing at low data rates, while 20 I/O pins drive relay drivers and read switch contacts directly. OTP memory holds fixed calibration tables for position memory and timing curves. Designers should verify the operating voltage range and temperature grade of the specific /SS variant against automotive underhood specifications before deployment. Compared to AEC-Q100 qualified parts, the PIC16C57 offers substantial cost savings for non-critical cabin modules.
추천
Simple Sensor Interface Modules
The PIC16C57-HSE/SS serves as an inexpensive sensor interface MCU that reads analog signals via an external ADC, processes thresholds, and drives indicator outputs or simple actuators. At 20 MHz it executes 8-bit signal conditioning algorithms (averaging, peak detection) within microseconds, suitable for thermistor bridges, optical sensors, and mechanical switches. The 3 KB OTP holds calibration coefficients and lookup tables for linearization curves. Watchdog timer and brownout reset ensure reliable recovery in unattended sensor installations. The 28-SSOP surface-mount package supports automated PCB assembly for volume sensor module production, and the low unit cost enables deployment in disposable or low-margin applications.
추천
Industrial Timer and Counter Modules
The PIC16C57-HSE/SS implements industrial timer and event-counter modules for conveyor control, machine cycle counting, and process timing applications where cost is more critical than flash reprogrammability. The on-chip 8-bit timer/counter with prescaler captures events up to 20 MHz, while 20 I/O pins drive indicator lamps and accept start/stop pushbuttons. The watchdog timer prevents lockup in 24/7 factory automation environments. OTP memory stores fixed timing constants and batch counter limits that rarely change after deployment. Compared to PLC modules, discrete PIC16C57-based timers offer dramatic cost savings for high-volume OEM equipment.
추천
Educational and Hobbyist Projects
The PIC16C57-HSE/SS remains popular for educational purposes and hobbyist projects where the simplicity of the PIC16C5X 33-instruction RISC architecture provides a clear learning platform. Programming is straightforward via the MPLAB PM3 universal programmer, and the absence of complex interrupt controllers allows students to focus on basic embedded concepts. The 3 KB OTP holds meaningful programs for line-following robots, simple games, and home automation prototypes. While new designs typically use PIC16F or PIC18 parts, the PIC16C57 is found in legacy kits and educational laboratories worldwide. The 28-SSOP package requires breakout boards for breadboard prototyping.

설계 노트
The PIC16C57-HSE/SS uses OTP (one-time-programmable) EPROM - code cannot be erased or rewritten after programming. Do not select this part for development or prototype runs unless you accept scrap cost on every code revision; use a JW (windowed) variant for code iteration, then move to /SS OTP for production. Verify programming equipment (e.g., MPLAB PM3) supports the PIC16C5X OTP algorithm before committing to high-volume production.
The 28-SSOP package has 0.65 mm pitch and requires careful PCB layout for hand-soldering; reflow or hot-air rework is strongly preferred for prototypes. Place decoupling capacitor (100 nF ceramic) within 5 mm of the VDD pins (27 and 28) and VSS pins (5 and 14). Route the OSC1/OSC2 traces short and guard them against adjacent switching signals to maintain clock integrity at 20 MHz.
The PIC16C57 typically operates from a single 5V supply (verify exact Vdd range in datasheet). At 20 MHz clock, supply current is approximately 5-10 mA active and < 1 uA in sleep mode; ensure bulk decoupling (10 uF electrolytic) plus local 100 nF ceramic for reliable operation. MCLR pin requires a 10 kohm pull-up to VDD for normal operation and a decoupling capacitor (typically 100 nF) if not driven by an external reset supervisor.
At 20 MHz OSC1/CLKIN input, treat the clock trace as a transmission line if it exceeds approximately 25 mm. Use a series resistor (33-100 ohm) close to the driving source to dampen reflections; the PIC16C57 datasheet specifies clock input rise/fall time requirements. For HS crystal mode, the load capacitors (typically 15-33 pF) must match the crystal's load capacitance specification to maintain frequency accuracy.
