1. Description
The AT28LV010 is a high-performance 3-volt only Electrically Erasable and Program-
mable Read-Only Memory. Its 1 megabit of memory is organized as 131,072 words by
8 bits. Manufactured with Atmel’s advanced nonvolatile CMOS technology, the device
offers access times to 200 ns with power dissipation of just 54 mW. When the device
is deselected, the CMOS standby current is less than 20 µA.
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
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 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 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 implemented to guard
against inadvertent writes. The device also includes an extra 128 bytes of EEPROM
for device identification or tracking.
