Microchip Technology WE128K32 series EEPROM module, part number WE128K32-140G2TC, offers a 4Mbit (128K x 32) non-volatile memory solution. This CMOS parallel interface device features a maximum access time of 140ns and can be configured as 512K x 8. It supports asynchronous operation with a programmable voltage of 5V and a supply voltage range of 4.5V to 5.5V. The WE128K32-140G2TC includes data polling and toggle bit functionality for efficient data management, along with hardware/software write protection. Endurance is rated at 100,000 write cycles, with a data retention of 10 years. This module is housed in a 68-lead ceramic CQFP package (JESD-30 Code S-CQFP-G68) suitable for surface mounting, with a terminal pitch of 1.27mm. Applications span industrial control, telecommunications, and aerospace sectors.
