PIC12C508A-04/SM

Product Summary

The PIC12C508A-04/SM is a low-cost, high performance, 8-bit, fully static, EEPROM/EPROM/ROM-based CMOS microcontroller. The PIC12C508A-04/SM employs a RISC architecture with only 33 single word/single cycle instructions. All instructions are single cycle (1 µs) except for program branches which take two cycles. The PIC12C508A-04/SM 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.
