Functional Description
The V62C1802048L 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 act-
ive LOW OE, and Tri-state I/O’s. This device has an auto-
matic 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-imped-
ance state when the device is deselected: the outputs are
disabled during a write cycle.
The V62C1802048LL comes with a 1V data retention feature
and Lower Standby Power. The V62C1802048L is available in
a 32-pin 8 x 13.4 & 8 x 20 mm TSOP1 / STSOP packages.
