DESCRIPTION
The
1+51
IS62LV1024L and IS62LV1024LL are low power
and low Vcc,131,072-word by 8-bit CMOS static RAMs. They
are fabricated using
1+51
's high-performance CMOS technol-
ogy. This highly reliable process coupled with innovative 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 IS62LV1024L and IS62LV1024LL are available in 32-pin
8*20mm TSOP-1, 8*13.4mm TSOP-1, 450mil SOP and 48-pin
6*8mm T.-BGA.
