(CE2) is HIGH. The I/O pins are placed in a high-imped-
ance state when the device is deselected: the outputs are d-
isabled during a write cycle.
TheV62C2801024LL comes with a 1V data retention feature
and Lower Standby Power. The V62C2801024L is available in
a 32pin 8 x 20 mm TSOP1 / STSOP / 48-fpBGA packages.

Functional Description
TheV62C2801024L is a low power CMOS Static RAM org-
anized as 131,072 words by 8 bits. Easy memory expansion is
provided by an active LOW CE1 , an active HIGH CE2, an
active LOW OE , and Tri-state I/O’s. This device has an a-
able 2 (CE2) HIGH. Reading from the device is performed
by taking Chip Enable 1 (CE1) with Output Enable
(OE ) LOW while Write Enable (WE) and Chip Enable 2
utomatic power-down mode feature when deselected.
Writing to the device is accomplished by taking Chip E-
nable 1 (CE1 ) with Write Enable (WE ) LOW, and Chip En-
