Functional Description

The V62C3801024L 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 a-

ctive LOW OE , and Tri-state I/O’s. This device has an au-

tomatic 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-

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

(CE2) is HIGH. The I/O pins are placed in a high-impeda-

nce state when the device is deselected: the outputs are di-

sabled during a write cycle.

The V62C3801024LL comes with a 2V data retention feature

and Lower Standby Power. TheV62C3801024L is available in

a 32-pin 8 x 20 mm TSOP1 / STSOP / 48-fpBGA pack-

ages.
