IC62LV1024AL IC62LV1024ALL
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 W (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 3.3V power supply
DESCRIPTION The ICSI IC62LV1024AL and IC62LV1024ALL are low power
and low Vcc,131,072-word by 8-bit CMOS static RAMs. They are fabricated using ICSI'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 IC62LV1024AL and IC62LV1024ALL 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. Test conditions assume signal transition times of 5 ns or less, timing reference levels of 1.5V, input pulse levels of 0.4V to 2.2V and output loading specified in Figure 1. 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.
