hi eduardo
have a look at this:-

The PIC12C6XX microcontroller (MCU) family packs Microchip’s powerful RISC-based 8-bit PICmicro® MCU architecture into 8-pin DIP and SOIC packages. The PIC12C6XX products feature a 14-bit instruction set, small package footprints, low operating voltage of 2.5 volts, interrupts handling, internal oscillator, on-board EEPROM data memory and a deeper stack.

hope this helps you
