FEATURES
DESCRIPTION
The ISSI IS62LV12816L is a high-speed, 2,097,152-bit static
RAM organized as 131,072 words by 16 bits. It is fabricated
usingISSI'shigh-performanceCMOStechnology. Thishighly
reliable process coupled with innovative circuit design
techniques, yields high-performance and low power
consumption devices.
• High-speed access time: 70, 100, and 120 ns
• CMOS low power operation
2
– 120 mW (typical) operating
– 6 µW (typical) CMOS standby
• TTL compatible interface levels
• Single 3V ± 10% VCC power supply
3
WhenCEisHIGH(deselected),thedeviceassumesastandby
mode at which the power dissipation can be reduced down
with CMOS input levels.
• Fully static operation: no clock or refresh
required
4
Easy memory expansion is provided by using Chip Enable
and Output Enable inputs, CEand 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.
• Three state outputs
• Data control for upper and lower bytes
• Industrial temperature available
5
• Available in the 44-pin TSOP (Type II) and
48-pin mini BGA
The IS62LV12816L is packaged in the JEDEC standard
44-pin TSOP (Type II) and 48-pin mini BGA.

of 0.4 to 2.2V 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 0.4V to
2.2V 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).
