Microchip Technology AT28HC256-90LC is a 262,144-bit (32K x 8) high-performance CMOS Electrically Erasable Programmable Read-Only Memory (EEPROM). This parallel interface device offers a fast 90ns access time and features automatic write and data polling capabilities. It operates from a single 5V supply voltage (4.5V to 5.5V) with a low standby current of 50µA and a maximum supply current of 80mA. The AT28HC256-90LC supports asynchronous operation and has a write cycle time of 10ms maximum. Its endurance is rated at 10,000 write cycles. This component is housed in a 32-pin Ceramic Chip Carrier (CQCC32) package, suitable for surface mounting. Applications include industrial control, data logging, and embedded systems requiring non-volatile data storage.
