The PIC16F72 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 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
- Only 35 single word instructions to learn
- All single cycle instructions except for program branches, which are two-cycle
- Operating speed: DC – 20 MHz clock input DC – 200 ns instruction cycle
- 2K x 14 words of Program Memory, 128 x 8 bytes of Data Memory (RAM)
