Microchip Technology's 28C64A-25I-TS is a 64 Kbit (8K x 8) CMOS EEPROM featuring a 250ns maximum access time. This parallel interface device operates asynchronously and supports automatic write and data polling functionalities, with a ready/busy output for status monitoring. The device is specified for an industrial operating temperature range of -40°C to +85°C and requires a supply voltage between 4.5V and 5.5V, with a nominal 5V operation. Its 28-lead TSOP package (JESD30 code R-PDSO-G28) offers a 0.5mm terminal pitch, suitable for surface-mount applications in industrial control, automotive, and consumer electronics. The 28C64 series provides a reliable solution for data storage in embedded systems.
