Features
1. Description
The AT28C64B is a high-performance electrically-erasable and programmable read-
only memory (EEPROM). Its 64K of memory is organized as 8,192 words by 8 bits.
Manufactured with Atmel’s advanced nonvolatile CMOS technology, the device offers
access times to 150 ns with power dissipation of just 220 mW. When the device is
deselected, the CMOS standby current is less than 100 µA.
The AT28C64B is accessed like a Static RAM for the read or write cycle without the
need for external components. The device contains a 64-byte page register to allow
writing of up to 64 bytes simultaneously. During a write cycle, the addresses and 1 to
64 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 write
the latched data using an internal control timer. The end of a write cycle can be
detected by DATA POLLING of I/O7. Once the end of a write cycle has been
detected, a new access for a read or write can begin.
Atmel’s AT28C64B has additional features to ensure high quality and manufacturabil-
ity. The device utilizes internal error correction for extended endurance and improved
data retention characteristics. An optional software data protection mechanism is
available to guard against inadvertent writes. The device also includes an extra
64 bytes of EEPROM for device identification or tracking.

... Read The AT28C64B is accessed like a Static RAM. 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 the high-impedance state when either high. This dual line control gives designers flexibility in preventing bus contention in their systems ...

... It should be noted that even after SDP is enabled, the user may still perform a byte or page write to the AT28C64B by preceding the data to be writ- ten by the same 3-byte command sequence used to enable SDP. Once set, SDP remains active unless the disable command sequence is issued. Power transi- tions do not disable SDP, and SDP protects the AT28C64B during power-up and power-down conditions ...
