I have seen a very interesting 8-bit family of microcontrollers, recently launched by Microchip: the PIC16F178X 8-bit advanced analog flash microcontrollers. What’s cool about those microcontrollers, it’s the fact that they have all kind of analog peripherals:

• 100 ksps 12 bit analog to digital converter
• 8-bit digital to analog converter
• three analog comparators
• two operational amplifiers
• a high performance PWM controller with two modules
