The PIC16C63A-20 is the high-speed 20 MHz variant of Microchip’s PIC16C63A 28-pin microcontroller, delivering 5 MIPS of processing performance—five times the execution speed of the 4 MHz variant. This increased performance enables higher baud rate serial communication, faster control loop response, more complex signal processing, and higher resolution timing measurements. The integrated USART module supports significantly higher baud rates at 20 MHz, up to 115.2 kbps and beyond with the high-speed baud rate generator mode, making it suitable for demanding serial communication applications. With 4096 words of OTP program memory and 192 bytes of RAM, the device provides ample resources for complex application code, communication protocol stacks, and data buffers. The three-timer architecture (8-bit TMR0, 16-bit TMR1, 8-bit TMR2) supports precision timing and PWM generation at higher resolutions than slower speed grades. The dual analog comparator module adds analog signal processing capability. The 22 I/O pins provide generous connectivity, with interrupt-on-change capability on Port B and a dedicated external interrupt pin. The commercial temperature rating (0°C to +70°C) covers most consumer and indoor industrial applications. The OTP memory model is ideal for high-volume production with proven firmware, offering excellent cost-performance ratio for high-speed applications.

The PIC16C63A-20 operates on Microchip’s mid-range PIC Harvard architecture with a 14-bit instruction set and 35 instructions. At 20 MHz clock frequency, the 4-cycle per instruction architecture yields a 5 MIPS execution rate, five times faster than the 4 MHz variant. The two-stage pipeline overlaps instruction fetch and execution, maximizing throughput. The 4096-word OTP program memory is addressed by a 12-bit program counter with an 8-level deep hardware stack for subroutine calls and interrupt service routines. The USART (Universal Synchronous/Asynchronous Receiver Transmitter) module provides full-duplex serial communication. At 20 MHz with the high-speed baud rate generator enabled (BRGH=1), the device can achieve baud rates up to 1250000 baud (1.25 Mbps) in asynchronous mode, supporting very high-speed serial data transfer. Standard rates such as 115200, 57600, and 38400 baud are also supported with good accuracy. Timer0 (8-bit), Timer1 (16-bit), and Timer2 (8-bit) each have prescalers and can be configured for various timing functions including PWM generation and input capture. The dual comparator module provides analog signal comparison with multiple configuration modes. The interrupt system handles multiple sources including USART TX/RX, timer overflows, external interrupt, and comparator output changes, enabling efficient event-driven programming at high speeds.
