Description

The 12C508A from Microchip Technology is a family of low-cost, high performance, 8-bit, fully static,EEPROM/EPROM/ROM-based CMOS microcontrollers.It employs a RISC architecture with only 33 single word/single cycle instructions. All instructions are single cycle (1 ms) except for program branches which take two cycles. The PIC12C5XX delivers performance an order of magnitude higher than its competitors in the same price category. The 12-bit wide instructions are highly symmetrical resulting in 2:1 code compression over other 8-bit microcontrollers in its class. The easy to use and easy to remember instruction set reduces development time significantly. 12C508A Features • 8-bit real time clock/counter (TMR0) with 8-bit programmable prescaler• Power-On Reset (POR)• Device Reset Timer (DRT)• Watchdog Timer (WDT) with its own on-chip RC oscillator for reliable operation• Programmable code-protection• 1,000,000 erase/write cycle EEPROM data memory• EEPROM data retention > 40 years• Power saving SLEEP mode• Wake-up from SLEEP on pin change• Internal weak pull-ups on I/O pins• Internal pull-up on MCLR pin• Selectable oscillator options:- INTRC: Internal 4 MHz RC oscillator- EXTRC: External low-cost RC oscillator- XT: Standard crystal/resonator- LP: Power saving, low frequency crystal 12C508A Applications The 12C508A fit perfectly in applications ranging from personal care appliances and security systems to low-power remote transmitters/receivers. The EPROM technology makes customizing application programs (transmitter codes, appliance settings,receiver frequencies, etc.) extremely fast and convenient, while the EEPROM data memory technology allows for the changing of calibration factors and security codes. The small footprint packages, for through hole or surface mounting, make this microcontroller series perfect for applications with space limitations. Low-cost, low-power, high performance, ease of use and I/O flexibility make the PIC12C5XX series very versatile even in areas where no microcontroller use has been considered before (e.g., timer functions, replacement of “glue” logic and PLD’s in larger systems, coprocessor applications)
