The PIC16F690-I/SO is a 8-bit/20-pin Flash-based CMOS Microcontroller with nanoWatt technology. The low pin-count (20) PIC® flash microcontroller products offer all of the advantages of the well recognized mid-range x14 architecture with standardized features including a wide operating voltage of 2 to 5.5V, on-board EEPROM data memory and nanoWatt technology. Standard analogue peripherals include up to 12-channels of 10-bit A/D, an analogue comparator module with two comparators, programmable on-chip voltage reference and an enhanced capture/compare/PWM (ECCP+) w/dead band delay, auto-shutdown and restart options. The oscillator module has a wide variety of clock sources and selection features that allow it to be used in a wide range of applications while maximizing performance and minimizing power consumption.
