IC61LV25616
256K x 16 HIGH SPEED ASYNCHRONOUS
CMOS STATIC RAM WITH 3.3V SUPPLY
FEATURES
DESCRIPTION
The ICSI IC61LV25616 is a high-speed, 4,194,304-bit static
RAM organized as 262,144 words by 16 bits. It is fabricated
using ICSI's high-performance CMOS technology. This highly
reliable process coupled with innovative circuit design
techniques, yields high-performance and low power consump-
tion devices.
• High-speed access time: 8, 10, 12, and 15 ns
• CMOS low power operation
• TTL compatible interface levels
• Single 3.3V ± 10% power supply
• Fully static operation: no clock or refresh
required
When CE is HIGH (deselected), the device assumes a standby
mode at which the power dissipation can be reduced down with
CMOS input levels.
• Three state outputs
• Data control for upper and lower bytes
• Industrial temperature available
Easy memory expansion is provided by using Chip Enable and
Output 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 IC61LV25616 is packaged in the JEDEC standard
44-pin 400mil SOJ, 44 pin 400mil TSOP-2 and 48-pin 6*8 TF-
BGA.

Notes:
1. Test conditions assume signal transition times of 3 ns or less, timing reference levels of 1.5V, input pulse levels of 0 to 3.0V and
output loading specified in Figure 1a.
2. Tested with the load in Figure 1b. Transition is measured ±500 mV from steady-state voltage. Not 100% tested.
3. 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.

Notes:
1. The internal Write time is defined by the overlap of CE = LOW, UB and/or LB = LOW, and WE = LOW. All signals must be
in valid states to initiate a Write, but any can be deasserted to terminate the Write. The tSA, tHA, tSD, and tHD timing is
referenced to the rising or falling edge of the signal that terminates the Write.
2. Tested with OE HIGH for a minimum of 4 ns before WE = LOW to place the I/O in a HIGH-Z state.
3. WE may be held LOW across many address cycles and the LB, UB pins can be used to control the Write function.
