The PIC12F683-I/SN is a 8-pin/8-bit flash-based CMOS Microcontroller with nanoWatt technology. The low pin-count (8) 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 to 5.5V, on-board EEPROM data memory. Standard analogue peripherals include up to 4 channels of 10-bit A/D, an analogue comparator module with a single comparator, programmable on-chip voltage reference and a standard capture/compare/PWM (CCP) module. The EEPROM data memory is readable and writable during normal operation (full VDD range). This memory is not directly mapped in the register file space. Instead, it is indirectly addressed through the special function registers.
