LPSR019-0A 11/13/2001 1 IC62VV25616L IC62VV25616LL 256K x 16 1.8V ULTRA LOW POWER CMOS STATIC RAM FEATURES DESCRIPTION The ICSI IC62VV25616L and IC62VV25616LL are low-power, • High-speed access times: 55, 70, 100 ns • CMOS low power operation ICC1=10mA (typical)* operating ISB2=1µA (typical)* CMOS standby * Typical values are measured at VCC=1.8V, TA=25°C • TTL compatible interface levels • Single 1.65V-2.2V Vcc power supply • Fully static operation: no clock or refresh required • Three state outputs • Data control for upper and lower bytes • Industrial temperature available • Available in the 44-pin TSOP-2 and 48-pin 6*8mm TF-BGA 4.194,304 bit static RAMs organized as 262,144 words by 16 bits. They are fabricated using ICSI's high-performance CMOS technology. This highly reliable process coupled with innovative circuit design techniques, yields high-performance and low power consumption devices. When CE is HIGH (deselected) or both LB and UB are HIGH, 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 Chip Enable Output and Enable inputs, CE and OE. The active LOW Write Enable (WE) controls both writing and reading of the memory. A data byte allows Upper Byte (UB) and Lower Byte (LB) access. The IC62VV25616L and IC62VV25616LL are packaged in the JEDEC standare 44-pin TSOP-2 and 48-pin 6*8mm TF-BGA.

Test conditions assume signal transition times of 5 ns or less, input pulse levels of 0.4V to 1.4V and output loading specified in Figure 1. 2. The internal write time is defined by the overlap of CE LOW, and UB or LB, 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. 3. Tested with the load in Figure 2.
