AT28LV010
2
The AT28LV010 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 writ-
ing 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 opera-
tions. Following the initiation of a write cycle, the device will
automatically write the latched data using an internal con-
trol 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 28LV010 has additional features to ensure high
quality and manufacturability. The device utilizes internal
error correction for extended endurance and improved data
retention characteristics. Software data protection is imple-
mented to guard against inadvertent writes. The device
also includes an extra 128 bytes of EEPROM for device
identification or tracking.
