DESCRIPTION

•
•
•
The ISSI IS61LV12816 is a high-speed, 2,097,152-bit static
RAM organized as 131,072 words by 16 bits. It is fabricated
using ISSI'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.
High-speed access time: 8, 10, 12, and 15 ns
CMOS low power operation
TTL and CMOS compatible interface levels
Single 3.3V ± 10% power supply
Fully static operation: no clock or refresh
required
• Three state outputs
• Data control for upper and lower bytes
• Industrial temperature available
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 IS61LV12816 is packaged in the JEDEC standard 44-pin
400-mil SOJ, 44-pin TSOP, 44-pin LQFP, and 48-pin mini
BGA (6mm x 8mm).

Notes:
1. Test conditions assume signal transition times of 3 ns or less, timing reference levels of 1.5V, input pulse levels
of 0V to 3.0V 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.

Notes:
1. Test conditions assume signal transition times of 3 ns or less, timing reference levels of 1.5V, input pulse levels of 0V
to 3.0V 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. 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 t SA, t HA, t SD, and t HD 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.
