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.
