DESCRIPTION
The 1+51 IC62LV2568L and IC62LV2568LL are low power
and low VCC, 262,144-bit words by 8 bits CMOS static RAMs.
They are fabricated using 1+51's high-performance CMOS
technology. This highly reliable process coupled with innova-
tive circuit design techniques, yields higher performance and
low power consumption devices.
When CE1 is HIGH or CE2 is LOW (deselected), the device
assumes a standby mode at which the power dissipation can
be reduced by using CMOS input levels.
Easy memory expansion is provided by using two Chip Enable
inputs, CE1 and CE2. The active LOW Write Enable (WE)
controls both writing and reading of the memory.
The IC62LV2568L and IC62LV2568LL are available in 32-pin
8*20mm TSOP-1, 8*13.4mm TSOP-1 and 48-pin 6*8mm T.-
BGA.
