FEATURES
DESCRIPTION
The ISSI IS61LV12816 is a high-speed, 2,097,152-bit static
RAM organized as 131,072 words bꢂ 16 bits. It is fabricated
ꢁsingISSI'shigh-performanceCMOStechnologꢂ. Thishighlꢂ
reliable process coꢁpled with innovative circꢁit design
techniqꢁes, ꢂields access times as fast as 8 ns with low power
consꢁmption.
• High-speed access time: 8, 10, 12, and 15 ns
• CMOS low power operation
• TTL and CMOS compatible interface levels
• Single 3.3V 10ꢀ power sꢁpplꢂ
• Fꢁllꢂ static operation: no clock or refresh
reqꢁired
When CE is HIGH (deselected), the device assꢁmes a
standbꢂ mode at which the power dissipation can be redꢁced
down with CMOS inpꢁt levels.
• Three state oꢁtpꢁts
• Data control for ꢁpper and lower bꢂtes
• Indꢁstrial temperatꢁre available
EasꢂmemorꢂexpansionisprovidedbꢂꢁsingChipEnableand
Oꢁtpꢁt Enable inpꢁts, CE and OE. The active LOW Write
Enable (WE) controls both writing and reading of the memorꢂ.
A data bꢂte allows Upper Bꢂte (UB) and Lower Bꢂte (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. 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 100ꢀ 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 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.
