IS62LV1024L
IS62LV1024L/LL
IS62LV1024LL
128K x 8 LOW POWER and LOW Vcc
CMOS STATIC RAM
FEATURES
• Access times of 45, 55, and 70 ns
• Low active power: 60 mW (typical)
• Low standby power: 15 µW (typical) CMOS
standby
• Low data retention voltage: 2V (min.)
• Available in Low Power (-L) and
Ultra Low Power (-LL)
• Output Enable (OE) and two Chip Enable
(CE1 and CE2) inputs for ease in applications
• TTL compatible inputs and outputs
• Single 2.7V to 3.6V power supply
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 technology. 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 TF-BGA.

Notes:
1. Stress greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause
permanent damage to the device. This is a stress rating only and functional operation of the
device at these or any other conditions above those indicated in the operational sections of
this specification is not implied. Exposure to absolute maximum rating conditions for
extended periods may affect reliability.

2. Tested with the load in Figure 2. Transition is measured ±500 mV from steady-state voltage. Not 100% tested.
3. The internal write time is defined by the overlap of CE1 LOW, CE2 HIGH and WE LOW. All signals must be in valid states to
initiate a Write, but any one can go inactive to terminate the Write. The Data Input Setup and Hold timing are referenced to the
rising or falling edge of the signal that terminates the Write.
4. Tested with OE HIGH.
