FUJITSU MB 1412A EIGHT-BIT SLICE ECC LSI
The MB 1412A is an 8-bit slice Error Checking and Correction (ECC) monolithic integrated circuit fabricated in a low-power Schottky TTL process. The device is utilized in memory system designs, and is suitahle for constructing 2-byte, 4-byte, or 8-byte ECC circuitry. The MB 1412A will detect and correct singlebit errors, and detect double-bit errors utilizing a built-in modified Hamming single-error-correction, double-error-detection (SEC-OED) code. A 64-pin square package with 100 mil pin spacing is utilized for the MB 1412A to provide high board packing density.
- 8-bit slice ECC function in one LSI.
- 100% single-bit error detection/correction and double-bit error detection.
- Simplified circuit design for 2, 4, or 8-byte memory systems. 4/8-byte system requires only 4/8 ECC circuits and 4/8 TTL SSI devices.
- Uses built-in modified Hamming SEC-OED Code.
- 4/8-byte data word requires only 7/8 check bits for full SEC-OED operation.
- High speed: 31/47 nsec. typical for 4/8-byte detect system, 40/56 nsec, for 4/8-byte correct.
CERAMIC PACKAGE PGA-64C-MO 1
- Low-power dissipation: 1.6 watts maximum. For 8-byte system, 8.7 watts typical system power including peripheral circuitry.
- Low-power SChottky TTL process; single +5 volt supply.
- Space-saving 64-pin square-pack with 100 mil pin...
