Description
The PIC16C72 belongs to the Mid-Range family of the PICmicro devices. The program memory contains 2K words which translate to 2048 instructions, since each 14-bit program memory word is the same width as each device instruction. The data memory (RAM) contains 128 bytes. There are also 22 I/O pins that are user-configurable on a pin-to-pin basis. Some pins are multiplexed with other device functions. These functions include: External interrupt Change on PORTB interrupt Timer0 clock input Timer1 clock/oscillator Capture/Compare/PWM A/D converter SPI/I2C
