During a byte write, the address and data are latched internally, freeing the microprocessor address and data bus for other operations. Following the initiation of a write cycle, the device will go to a busy state and automatically clear and write the latched data using an internal control timer. The end of a write cycle can be determined by DATA polling of I/O7. Once the end of a write cycle has been detected, a new access for a read or a write can begin. The CMOS technology offers fast access times of 250 ns at low power dissipation. When the chip is deselected the standby current is less than 50 µA. Atmel’s 28BV16 has additional features to ensure high quality and manufacturability. The device utilizes error correction internally for extended endurance and for improved data retention characteristics. An extra 32-bytes of EEPROM are available for device identification or tracking.

When CE and OE are low and WE is high, the data stored at the memory location determined by the address pins is asserted on the outputs. The outputs are put in a high impedance state whenever CE or OE is high. This dual line control gives designers increased flexibility in preventing bus contention.
