The AT28C010 is a high-performance EEPROM with 1 megabyte of storage space organized as 131,072 8-bit words. Manufactured with Atmel's advanced nonvolatile CMOS technology, the device offers access times to 120 ns with power dissipation of just 220 mW. When the device is deselected, the CMOS standby current is less than 200 µA. The AT28C010 is accessed like a Static RAM for the read or write cycle without the need for external components. The device contains a 128-byte page register to allow writing of up to 128 bytes simultaneously. During a write cycle, the address and 1 to 128 bytes of data are internally latched, freeing the address and data bus for other operations. Following the initiation of a write cycle, the device will automatically complete the page write operation.
