Microchip Technology WE128K32 series EEPROM module, part number WE128K32-140H1MA, offers a 4Mbit (128K x 32) parallel CMOS memory solution. This component provides a fast 140ns maximum access time and supports a wide operating temperature range from -55°C to +125°C. The WE128K32-140H1MA is configurable as 512K x 8 and features data polling and a toggle bit for efficient status monitoring. Designed for robust performance, it boasts a data retention of 10 years and an endurance rating of 100,000 write cycles. The module operates asynchronously with a supply voltage range of 4.5V to 5.5V and a nominal 5V. It is housed in a 66-pin Ceramic Pinned Grid Array (CPGA) package, measuring 27.3mm x 27.3mm. Applications for this type of memory include industrial control, aerospace, and defense systems.
