Functional Description
The V62C1801024L is a low power CMOS Static RAM or-
ganized 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-
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 Ena-
ble 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 st-
ate when the device is deselected: the outputs are disabled
during a write cycle.
The V62C1801024LL comes with a 1V data retention feature
and Lower Standby Power. The V62C1801024L is available in
a 32-pin 8 x 20 mm TSOP1 / STSOP / 48-fpBGA packages.
