The Microchip Technology 28C64A-20I-K is a 64 Kbit (8K x 8 bit) CMOS EEPROM. This parallel interface device offers a maximum access time of 200ns and operates with a 5V supply. Key features include automatic write, data polling, and ready/busy status, facilitating efficient data management. The device utilizes a 32-terminal CQCC package (JESD30 R-CQCC-N32) with a terminal pitch of 1.27mm. Operating within an industrial temperature range of -40°C to +85°C, the 28C64A-20I-K is suitable for applications requiring non-volatile data storage, such as industrial control systems, automotive electronics, and embedded systems. Its CMOS technology ensures low standby current, while the parallel interface supports straightforward integration into existing designs.
