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.

Notes:
1. 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. Transition is measured ±500 mV from steady-state voltage. Not 100% tested.

Notes:
1. WRITE is an internally generated signal asserted during an overlap of the LOW states on the CE and WE inputs and at least
one of the LB and UB inputs being in the LOW state.
2. WRITE = (CE) [ (LB) = (UB) ] (WE).
