DESCRIPTION
The
1+51
IS61LV6416 is a high-speed, 1,048,576-bit static
RAM organized as 65,536 words by 16 bits. It is fabricated
using
1+51
's high-performance CMOS technology. This highly
reliable process coupled with innovative circuit design
techniques, yields access times as fast as 8 ns with low power
consumption.
When
CE
is HIGH (deselected), the device assumes a standby
mode at which the power dissipation can be reduced down with
CMOS input levels.
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 IS61LV6416 is packaged in the JEDEC standard 44-pin
400mil SOJ, 44-pin 400mil TSOP-2, and 48-pin 6*8mm 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. Not 100% tested.
