Functional Description

The V62C3802048L is a low power CMOS Static RAM orga-

nized as 262,144 words by 8 bits. Easy memory expansion is p-

rovided by an active LOW CE1, an active HIGH CE2, an acti-

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

atic power-down mode feature when deselected.

Writing to the device is accomplished by taking Chip En-

able 1 (CE1) with Write Enable (WE ) LOW, and Chip Enab-

le 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-impedance sta-

te when the device is deselected: the outputs are disabled d-

uring a write cycle.

The V62C3802048LL comes with a 1V data retention feature

and Lower Standby Power. The V62C3802048L is available in

a 32-pin 8 x 20 mm TSOP1/8 x 13.4mm STSOP and CSP type

48-fpBGA packages.
