PIC16F636-E/P

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 2.0...5.5 volts, on-board EEPROM data memory, and nanoWatt Technology. Standard analog peripherals include up to 12 channels of 10-bit A/D, an analog 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.
