The PIC16F690-I/SS is a 8-bit Flash-based CMOS Microcontroller with nanoWatt technology. The low pin-count (20) PIC® flash microcontroller offers all of the advantages of the well recognized mid-range x14 architecture with standardized features including a wide operating voltage of 2.0 to 5.5V and on-board EEPROM data memory. 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+) with dead band delay, auto-shutdown and restart options.
