PIC16C57T-HSE/SO - 8-bit OTP MCU 3KB 20MHz 28-SOIC | Microchip
MPN: PIC16C57T-HSE/SO ✓ Hoạt độngPIC16C57T-HSE/SO Tóm tắt
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, working RAM, and peripheral I/O on one die. The PIC16C5X family belongs to Microchip's classic PIC baseline architecture (hypernyms: microcontroller -> embedded processor -> semiconductor -> integrated circuit). These parts are fully static, meaning the clock can be stopped without losing register state, and they execute one instruction per internal clock cycle, which simplifies timing analysis compared with accumulator-based 8-bit MCUs.
Key features of the PIC16C57T-HSE/SO include 12 I/O pins, an 8-bit timer/counter, a Watchdog Timer with on-chip RC oscillator, Power-on Reset, Power-saving Sleep mode, code protection, and selectable oscillator options (HS = high-speed crystal/ceramic, where the "E" indicates the extended-temperature variant). The EPROM-based OTP memory allows rapid prototyping before committing to a masked-ROM version for high-volume production.
Typical applications include appliance controllers, automotive subsystems (body electronics, instrument clusters), industrial control (sensor interfaces, motor drives), and consumer products (remote controls, toys). The wide operating voltage range and rugged CMOS design make it suitable for harsh electrical environments.
When designing with this MCU, note that the OTP memory cannot be electrically erased; for in-circuit reprogrammability, choose a Flash-based PIC16F5X equivalent. Always include proper decoupling (0.1uF) near the VDD pin and respect the maximum oscillator frequency versus VDD relationship specified in the datasheet.

Ứng dụng tiêu biểu
PIC16C57T-HSE/SO phù hợp cho 6 Áp dụngs: Appliance Control Boards, Automotive Body Electronics, Industrial Sensor Interfaces, Remote Controls and IR Transmitters, Toys and Educational Electronics, Security and Access-Control Panels.
Appliance Control Boards
The PIC16C57T-HSE/SO fits appliance controllers such as washing-machine front panels, microwave keypads, and dishwasher cycle timers. Its 3KB OTP memory holds typical appliance state machines (washing cycles, drying profiles, defrost schedules), while 20 GPIO drive 7-segment displays, relay coils, and triac optocouplers. With 20MHz HS-oscillator capability, it executes scan loops in tens of microseconds - fast enough to debounce mechanical keypads in software without external filters. The 28-SOIC package survives the high-temperature reflow profiles required by consumer appliance manufacturing lines.

Automotive Body Electronics
The PIC16C57T-HSE/SO powers automotive body-electronics modules including door-lock controllers, seat-position memories, wiper interval timers, and instrument-cluster auxiliary logic. Its 8-bit PIC RISC core runs simple body-control state machines in tens of microseconds, leaving margin for CAN/LIN bit-banging when no hardware peripheral is present. The wide 28-SOIC footprint simplifies PCB layout in head-unit modules where thermal cycling and vibration tolerance are essential. Automotive designers should select the PIC16C57-HSE/SO extended-temperature grade or migrate to AEC-Q100 qualified PIC16F5X parts for underhood applications.

Industrial Sensor Interfaces
In industrial sensor interfaces such as 4-20mA loop transmitters, photoelectric switches, and proximity-detector signal conditioners, the PIC16C57T-HSE/SO provides the timing precision and GPIO flexibility needed to measure analog sensors and drive indicator LEDs or alarm relays. Its 8-bit ADC-free architecture pushes analog conditioning to external op-amps (e.g. MCP6002), while the MCU handles linearization, calibration, and HART-style bit-banging. The 20MHz clock enables 10us ADC-conversion plus processing loops, sufficient for 100Hz update rates typical in process-control loops.

Remote Controls and IR Transmitters
Consumer remote controls for TVs, set-top boxes, and audio systems use the PIC16C57T-HSE/SO to scan key matrices, encode NEC/RC-5 IR protocols, and manage low-battery shutdown. With 3KB OTP, the firmware easily fits the entire key-scan table plus protocol encoder; the 20MHz HS oscillator supports carrier frequencies of 36-56kHz with sub-microsecond timing accuracy. The 28-SOIC package is widely accepted on low-cost consumer PCBs, and Sleep mode plus the internal Watchdog Timer enable multi-year battery life on 2xAAA cells.
Được đề xuất
Toys and Educational Electronics
The PIC16C57T-HSE/SO is a workhorse in low-cost educational electronics kits and electronic toys where the OTP memory prevents end-user firmware tampering, the 28-SOIC is robust enough to survive student handling, and the 20MHz clock drives sound-effects generation through PWM and LED chase patterns. With 20 GPIO, it can drive 5x5 LED matrices, hobby servos, and small DC motor bridges via discrete drivers. Its PIC baseline architecture is widely taught in universities, simplifying onboarding for student design teams.

Security and Access-Control Panels
Security alarm panels and access-control keypads use the PIC16C57T-HSE/SO to scan 4x4 or 8x8 matrix keypads, drive piezo buzzers for arm/disarm chirps, and bit-bang serial protocols to RF or GSM modules. The 3KB OTP holds user codes, event logs, and arming-state machines; the 20MHz clock decodes DTMF or Manchester-encoded signals within 100us windows. The 28-SOIC package is favored in legacy security installations, where service technicians need through-hole-friendly footprints with SMD-repair compatibility.

Ghi chú thiết kế
Estimated: at VDD=5V and 20MHz, the PIC16C57T-HSE/SO typically draws 15-25mA active and 1-5uA in Sleep mode. Place a 0.1uF ceramic decoupling capacitor within 5mm of the VDD pin (pin 4) and a bulk 10uF tantalum or aluminum capacitor near the MCU to suppress digital switching noise. Add a series ferrite bead on the supply trace if the board shares a 5V rail with motors or relays to prevent conducted EMI from disturbing the MCU's internal POR circuit.
The HS oscillator mode requires a 4-20MHz fundamental-mode crystal or ceramic resonator with appropriate load capacitors (typically 15-33pF). Use series resistor (~100 ohm) only if the oscillator gain is too high and causes overtone operation. For designs that may see cold-start temperatures below 0C, choose a crystal with a low equivalent series resistance (ESR<60 ohm) to ensure reliable start-up. The CL1/CL2 oscillator pins can also be driven by an external CMOS clock source up to 20MHz.
The PIC16C57 OTP memory cannot be electrically erased - mistakes in code are permanent. Plan firmware revision-control discipline before programming production units. The /T suffix denotes Tape & Reel, NOT a temperature grade - do not confuse it with the 'I' (industrial) or 'E' (extended) suffixes. Always check that the MCLR pin (pin 1) has a proper pull-up resistor (typically 10kohm to VDD); leaving it floating causes intermittent resets. Avoid using GP3 as an input if you also need MCLR functionality, as the two share the same pin.
