Industry's first 500,000-write performance and 50-year data retention at 125
degrees C
TOKYO, Aug. 3 /PRNewswire/ -- Seiko Instruments (SII) announced
availability of the S-25A series of SPI Serial EEPROMs, specifically designed
for use in the highly demanding automotive market. The ground-breaking S-25A
EEPROMs set industry performance records by achieving 500,000 writes at 125
degrees C, and up to 50-year data retention.
Today's automobile designs increasingly require higher performance EEPROMs
in on-board systems that control the car's operation, fuel consumption, and
ensure the passenger's comfort and safety. Along with the requirement for
increased EEPROM capacity, automotive applications also require extremely high
reliability and security. The SII S-25A series was developed to specifically
answer the needs of the automotive market.
While conventional EEPROMs typically have significantly degraded write
performance at high temperature, the S-25A series assures performance of up to
500,000 writes at 125 degrees C, and 1,000,000 writes at 85 degrees C, along
with retention of the EEPROM data for as long as 50 years.
Using SII's proprietary know-how, the new EEPROMs are screened to
eliminate electronic leakage bit-errors; achieve a 4-ms write time (5 to 10 ms
is typical for other manufacturers); and use special low power and voltage
fluctuation detection circuits to prevent errors caused by electrical noise or
variations.
Typical automotive applications include engine, transmission, and EPS
control systems; ABS, ESC (Electronic Stability Control), and airbags;
key-less entry, air-conditioning, dashboard displays, and BCM (Body Control
Module). The S-25A series is offered in a wide range of memory capacities from
1k to 64k. SII forecasts sales of 10 million pieces annually.
