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.
