PIC16C63AT-20E/SS - 8-Bit 20MHz OTP MCU, 7KB | Microchip
MPN: PIC16C63AT-20E/SS ✗ Cuối đờiPIC16C63AT-20E/SS Tóm tắt
An 8-bit OTP microcontroller (one-time programmable microcontroller) is a class of embedded controller that stores its program in non-volatile memory programmed once at production, retaining code without external storage and offering lower per-unit cost than flash-based equivalents for high-volume mature products. Within the broader taxonomy, the PIC16C63A sits at: PIC16C63A -> PIC16C6xx mid-range family -> PIC16 family -> 8-bit PIC microcontroller -> embedded microcontroller -> integrated circuit -> semiconductor. OTP parts sit alongside EPROM-windowed and flash variants in Microchip's classic PIC16C lineup.
Key differentiating features of the PIC16C63AT-20E/SS include its 20 MHz MIPS performance at 5V operation, integrated synchronous serial port (MSSP) supporting both SPI and I2C master/slave modes, an enhanced USART with autobaud detection, and the PIC mid-range 14-bit instruction set that delivers single-cycle execution except for branch instructions. The 28-SSOP package provides a compact 5.30 mm body width suitable for space-constrained industrial controller boards.
The PIC16C63A is built on a fully-static CMOS process, allowing the clock to be stopped without losing register state - a useful feature for low-power sleep/awake control loops. The OTP program memory and the absence of internal flash make this part best suited to high-volume production where firmware is final and one-time programming cost is acceptable, with field updates typically handled via board-level replacement or external bootloader memory.
Typical applications include industrial automation controllers, automotive body and chassis ECUs, consumer appliance control boards, and sensor interface modules where the PIC16 mid-range instruction set and 5V-tolerant I/O are required. The wide 4V-5.5V supply tolerance supports unregulated 5V rails common in industrial installations.
When designing with this part, ensure the OTP programming step is performed before final assembly or via on-board programming through the ICSP interface; field firmware updates are not possible on this device. Decoupling VDD/VSS with 100 nF ceramic capacitors placed within 5 mm of the pins is required for EMI suppression on the analog and digital rails.

Ứng dụng tiêu biểu
PIC16C63AT-20E/SS phù hợp cho 6 Áp dụngs: Industrial Automation Controllers, Automotive Body and Chassis ECUs, Consumer Appliance Control Boards, Sensor Interface Modules, HVAC and Building Automation, Point-of-Sale Terminals and Peripherals.
Industrial Automation Controllers
The PIC16C63AT-20E/SS fits industrial PLC and sensor-hub applications because its 20 MHz core, 7 KB OTP program memory, and 22 digital I/O pins provide enough headroom for closed-loop control loops at modest update rates. The extended -40C to +125C temperature grade and 4V-5.5V supply tolerance handle unregulated 24V-derived industrial rails. Place decoupling on VDD/VSS within 5 mm of pins and route the 20 MHz crystal trace symmetrically to OSC1/OSC2 to meet IEC 61000-4-2 EMI margins in factory-floor enclosures.
Được đề xuất
Automotive Body and Chassis ECUs
The PIC16C63AT-20E/SS is well-suited to body control modules (window lifters, mirror controllers, simple lighting drivers) where its 8-bit PIC mid-range core, 192 bytes RAM, and 22 I/O can scan a switch matrix and drive relay/H-bridge outputs at deterministic rates. The MSSP peripheral supports I2C communication with sensor clusters and the USART provides LIN-bus-friendly asynchronous serial capability when paired with a LIN transceiver. Note that AEC-Q100 qualification status was not confirmed in the provided data - use the 'Q' automotive suffix variant if available.
Được đề xuất
Consumer Appliance Control Boards
The PIC16C63AT-20E/SS is widely used in washing machine, dishwasher, and microwave control boards where its 7 KB OTP memory holds a fixed appliance state machine, 192 bytes RAM is enough for parameter buffers, and the 8-channel 8-bit ADC reads thermistor/timer inputs directly. The 'T' tape-and-reel packaging supports high-volume pick-and-place assembly. The 20 MHz instruction throughput handles key debounce, segment LCD multiplexing, and triac zero-crossing firing in real time without dropping cycles.
Được đề xuất
Sensor Interface Modules
The PIC16C63AT-20E/SS fits 4-20 mA loop-powered and Modbus sensor transmitter designs because its USART and MSSP (SPI/I2C) cover both legacy 2-wire industrial protocols and modern digital sensor interfaces. The 8-channel ADC paired with the 20 MHz core can run digital filtering and linearization in firmware, eliminating external DSP. Use the 'E' extended temperature grade for outdoor or process-plant sensor housings, and route ADC AVss separately from digital Vss to preserve 8-bit conversion accuracy across the industrial temperature range.
Được đề xuất
HVAC and Building Automation
The PIC16C63AT-20E/SS handles thermostat, damper actuator, and fan-coil-unit controllers where its 22 I/O can scan keypad input, drive LCD segments, and pulse-step relay outputs from a single chip. The 4-5.5V supply tolerance accepts rectified 24VAC wall transformers common in HVAC installations, and the -40C to +125C industrial grade supports unconditioned equipment-room mounting. The CCP/PWM module generates smooth TRIAC phase-angle control without software jitter when triggered from a hardware timer interrupt.
Được đề xuất
Point-of-Sale Terminals and Peripherals
The PIC16C63AT-20E/SS suits POS scanner modules, magnetic-stripe readers, and thermal-printer controllers where deterministic 20 MHz execution handles serial scanner decoding and stepper-motor pulse streams. The 192-byte RAM is sufficient for buffer-based packet reassembly, and the MSSP I2C master interfaces to EEPROM and crypto-authentication ICs. Because the OTP memory locks firmware at production, this part is ideal for tamper-resistant financial peripherals where field code modification must be physically prevented.

Ghi chú thiết kế
Place a 100 nF X7R ceramic decoupling capacitor within 5 mm of the VDD pin (pin 9) and a second 100 nF capacitor on the VSS pin (pin 19) to suppress switching noise on the digital supply rail. For ADC accuracy, add a 10 uF bulk capacitor and a separate analog AVss path if the application reads the 8-bit ADC channels - sharing digital and analog ground at a single point under the package reduces conversion noise by 1-2 LSB. The PIC16C63AT-20E/SS operates from 4V to 5.5V; do not exceed 5.5V absolute maximum or the OTP memory row may be corrupted during in-circuit programming.
Route the 20 MHz crystal (or ceramic resonator) symmetrically to OSC1 (pin 10) and OSC2 (pin 20) with trace lengths matched within 2 mm and surrounded by a ground pour on both sides of the trace pair. Keep crystal traces shorter than 10 mm to avoid EMI pickup and ensure clean clock edges. The MCLR/VPP pin (pin 1) requires a 10 kohm pull-up to VDD; do not leave it floating or the part may intermittently reset. For ICSP programming, expose the PGC (RB6) and PGD (RB7) pins on a 5-pin header per the Microchip ICSP specification.
Do not assume OTP program memory can be re-written in the field - once programmed, the PIC16C63AT-20E/SS cannot be erased, so any firmware bug requires physical replacement of the device. Verify firmware revision on prototypes using the JW (windowed) package first, then lock in the OTP/SS variant for production. The 'T' suffix on the part number denotes tape-and-reel packaging for pick-and-place assembly; do not confuse it with TBD-grade or a revision letter. Also note that the 04 MHz speed-bin parts share the same pinout but cannot be clocked above 4 MHz, so de-rate your instruction timing accordingly.
