Microchip Technology 28C64B-90B-XB is a 64-kilobit CMOS EEPROM organized as 8K words by 8 bits. This parallel interface memory offers a fast 90ns access time and operates over a wide temperature range of -55°C to +125°C. Featuring data polling and ready/busy status for efficient read and write operations, this component is suitable for applications requiring non-volatile data storage in harsh environments, including aerospace, defense, and industrial control systems. The device is housed in a 28-pin ceramic dual in-line package (CDIP28) with through-hole mounting. Its 5V supply voltage and 80mA maximum operating current are standard for its class. The 28C64 series provides reliable data retention and endurance for demanding embedded systems.
