MC9S12K-Family

Product Preview

16-Bit Microcontroller

Targeted for ultra high reliability systems, members of the MC9S12K-Family of 16-bit Flash-based microcontrol-

lers have an increased performance in reliability over the life of the product. The improvement is due to a built-in

Error Checking and Correction code (ECC) in the Flash memory. The program and erase operations automatically

generate six parity bits per word making ECC transparent to the end user. The ECC logic implements a modified

Hamming code capable of correcting single bit faults and detecting double bit faults in each word. The MC9S12K-

Family members are composed of standard on-chip peripherals and maintain pin compatibility with the

MC9S12D-Family.
