PIC16C63T-20I/SO 概要
A PIC microcontroller (Peripheral Interface Controller) is a family of Harvard-architecture microcontrollers originally developed by Microchip Technology that integrate a CPU, memory (program ROM/Flash/OTP and RAM), and peripheral interfaces (timers, ADC, PWM, communication ports) into a single IC. Within the broader taxonomy, PIC16C63 sits in the hierarchy: PIC16Cxx -> mid-range PIC -> 8-bit microcontroller -> microcontroller -> embedded IC -> semiconductor. The 'C' designation indicates CMOS EPROM/OTP technology, distinguishing it from the Flash-based 'F' variants (such as PIC16F716). These OTP devices are intended for volume production where firmware is finalized and in-circuit reprogrammability is not required.
Key features of the PIC16C63T-20I/SO include integrated peripherals such as Brown-out Detect/Reset (BOR), Power-On Reset (POR), Pulse Width Modulation (PWM) outputs, and a Watchdog Timer (WDT) for reliable embedded operation. The device operates from a 5V supply (typical), with a DC to 20MHz clock range. Its compact 28-SOIC package and industrial temperature range make it suitable for through-hole-replacement surface-mount designs in industrial control and consumer embedded systems.
Typical applications include industrial control logic, sensor interface modules, motor control signal generation via PWM, simple communication bridging using USART, and white-goods/appliance control boards. The combination of OTP memory and industrial-grade temperature rating suits mature, cost-sensitive production designs where firmware stability and predictable cost over the product lifecycle are essential.
When designing with this device, note that OTP memory is one-time programmable and cannot be re-flashed, so firmware must be fully validated before programming. Use the MPLAB PM3 Universal Device Programmer or equivalent EPROM programmer. For designs requiring in-circuit reprogrammability, consider the PIC16F63 or PIC16F716 Flash-based equivalents in the same 28-SOIC footprint.

主な用途
PIC16C63T-20I/SO の用途: 6 件s: Industrial Control Logic Boards, Sensor Interface Modules, PWM Motor Speed Control, White Goods Appliance Control, USART Communication Bridging, Automotive Cabin Electronics.
Industrial Control Logic Boards
The PIC16C63T-20I/SO fits industrial control logic boards because its 20MHz RISC core delivers single-cycle instruction execution (200ns at full speed) for deterministic timing of relay and solenoid control loops, while the integrated PWM module generates motor drive signals without external timer ICs. Its industrial -40C to +85C temperature grade tolerates factory floor thermal stress, and the 22 I/O pins handle multiple sensor inputs and actuator outputs per board. The Brown-out Detect and Power-On Reset peripherals protect against supply brown-outs common in industrial 24V bus systems. Use it where firmware is finalized and the unit-cost advantage of OTP memory outweighs the flexibility of Flash reprogramming.
おすすめ
Sensor Interface Modules
The PIC16C63T-20I/SO suits sensor interface modules where it reads analog or digital sensors via its I/O ports, performs signal conditioning in firmware, and forwards data over USART to a host controller. The 192-byte RAM accommodates small data buffers for sampled sensor streams at modest rates (under 10kHz), while 7KB OTP holds signal-processing lookup tables and calibration coefficients. The Watchdog Timer (WDT) auto-recovers the module from firmware lockups in unattended field installations. Industrial temperature operation supports outdoor or cabinet-mounted sensor enclosures without additional thermal management.
おすすめ
PWM Motor Speed Control
The PIC16C63T-20I/SO is well-suited for low-power DC motor speed control where its integrated PWM peripheral generates variable-duty drive signals at up to 20MHz timer resolution, eliminating external PWM ICs. The 5V supply and 22 I/O pins interface directly to H-bridge gate drivers (such as the L293D or DRV8871) for brushed DC motors in appliance and small-equipment applications. The Brown-out Detect feature prevents motor driver latch-up during supply transients, and the industrial temperature grade supports under-hood or compartment-mounted designs. OTP memory locks in calibrated speed profiles once the design is production-ready, reducing per-unit cost.
おすすめ
White Goods Appliance Control
The PIC16C63T-20I/SO fits white-goods appliance control boards (washing machines, dishwashers, microwave ovens) where the 8-bit core runs state-machine firmware for cycle sequencing, the integrated PWM drives motor and heater elements, and the USART interfaces to display or keypad panels. OTP memory is acceptable for high-volume production runs of 10k+ units where per-part cost savings outweigh reprogramming flexibility. The -40C to +85C industrial temperature range tolerates appliance compartment heat, and the Watchdog Timer recovers from line-voltage glitches common in consumer mains environments.
おすすめ
USART Communication Bridging
The PIC16C63T-20I/SO works as a serial protocol bridge between subsystems where its integrated USART module converts between TTL UART, RS-232, RS-485, or LIN bus protocols at baud rates up to its 20MHz timer resolution. The 7KB OTP program memory accommodates protocol translation tables and small framing state machines, while 192 bytes of RAM buffers inbound/outbound byte streams. The device's CMOS low-power characteristics suit battery-backed communication modules in industrial telemetry, and OTP locking prevents accidental firmware corruption in field-deployed bridging nodes.
おすすめ
Automotive Cabin Electronics
The PIC16C63T-20I/SO supports automotive cabin electronics applications (HVAC control, seat controllers, interior lighting, dashboard accessory modules) where its 20MHz core runs control loops, its PWM channels drive LED dimmers and small motors, and its industrial temperature range tolerates cabin thermal extremes. However, note this is NOT an AEC-Q100 qualified part - for under-hood or safety-critical automotive designs, migrate to AEC-Q100-qualified Flash parts such as PIC16F1936-I/SO or dsPIC33 variants. The OTP memory suits high-volume production runs with locked firmware.

設計ノート
OTP memory is one-time programmable and cannot be erased. Always validate firmware on a windowed PIC16C63 (PIC16C63JW) prototype or a Flash-based equivalent (PIC16F63, PIC16F72) before committing production units. A single code bug means scrapping the programmed MCU. Use the Microchip MPLAB PM3 or equivalent EPROM programmer; verify blank check and programming verification at 4.5V and 5.5V supply extremes before high-volume runs.
The PIC16C63T-20I/SO requires a stable 5V +/- 10% supply. Add a 100nF ceramic decoupling capacitor as close as possible to VDD (pin 20) and a bulk 10uF electrolytic on the supply rail. The MCLR pin (pin 1) must be pulled high through a 10k resistor with a 100nF capacitor to ground for proper Power-On Reset timing. Brown-out Detect (BOR) should be enabled in the configuration word to reset the MCU on supply droops below 4V.
Place the 28-SOIC decoupling capacitor within 5mm of VDD pin 20. For crystal oscillator operation, keep the crystal and load capacitors close to OSC1/OSC2 (pins 9/10) with short trace lengths to minimize EMI and startup time. For high-speed designs above 10MHz, add a 4.7k pull-up on MCLR to ensure clean reset. Route RC6/RC7 (USART) away from PWM outputs (RC2/CCP1) to reduce crosstalk on noisy motor drive boards.
コンプライアンス情報
RoHS and REACH status not explicitly stated in verified web data. This part is OTP/EPROM technology predating widespread RoHS transition; the original PIC16C63 family was launched before RoHS deadlines. Not AEC-Q100 qualified - not suitable for safety-critical automotive. For AEC-Q100 automotive designs, use qualified Flash parts in the same 28-SOIC footprint.
