Microchip Technology 28C64A-20-K is a 65536-bit CMOS electrically erasable programmable read-only memory (EEPROM) organized as 8K words by 8 bits. This parallel interface device features a maximum access time of 200ns, supporting asynchronous operation. The 28C64 series offers automatic write, data polling, and ready/busy signals for efficient data management. It operates from a 4.5V to 5.5V supply voltage range and is housed in a 32-terminal CQCC (Ceramic Quad Flatless Chip Carrier) package. Typical applications include industrial control, medical equipment, and telecommunications systems requiring non-volatile data storage. The component exhibits a standby current of 100µA and a maximum supply current of 30mA during active operation. Write cycle time is specified at a maximum of 1.0ms.
