Description

The Intersil ACS630MS is a Radiation Hardened 16-bit parallel

error detection and correction circuit. It uses a modified Hamming code to generate a 6-bit check word from each 16-bit data

word. The check word is stored with the data word during a

memory write cycle; during a memory read cycle a 22-bit word is

taken form memory and checked for errors. Single bit errors in

the data words are flagged and corrected. Single bit errors in

check words are flagged but not corrected. The position of the

incorrect bit is pinpointed, in both cases, by the 6-bit error

syndrome code which is output during the error correction cycle.

The ACS630MS utilizes advanced CMOS/SOS technology to

achieve high-speed operation. This device is a member of a

radiation hardened, high-speed, CMOS/SOS Logic Family.

The ACS630MS is supplied in a 28 lead Ceramic Flatpack (K

suffix) or a 28 Lead Ceramic Dual-In-Line Package (D suffix).
