Microchip Technology presents the 28C64AX-25I-K, a 64-kilobit (8K x 8) CMOS Parallel EEPROM. This component offers a maximum access time of 250ns and features automatic write capabilities with data polling for efficient programming. Operating asynchronously, it utilizes a parallel interface and is housed in a 32-terminal Ceramic Quad Flat No-Lead (CQFN) package with a terminal pitch of 1.27mm. The 28C64 series is suitable for applications requiring non-volatile data storage across industrial temperature ranges from -40°C to +85°C. Key specifications include a supply voltage range of 4.5V to 5.5V and a standby current of 100µA. This device is well-suited for embedded control, industrial automation, and data logging systems.
