This powerful (200 nanosecond instruction execution) yet easy-to-program (only 35 single word instructions) CMOS OTP-based 8-bit microcontroller packs Microchip"s powerful PIC® architecture into an 28-pin package and is upwards compatible with the PIC16C5X and PIC12CXXX devices. The PIC16C72A features 5 channels of 8-bit Analog-to-Digital (A/D) converter with 2 additional timers, a capture/compare/PWM function and the synchronous serial port can be configured as either 3-wire Serial Peripheral Interface (SPI) or the 2-wire Inter-Integrated Circuit (I²C) bus. All of these features make it ideal for more advanced level A/D applications in automotive, industrial, appliances and consumer applications.
