PRELIMINARY INFORMATION
FEBRUARY 2000
FEATURES
DESCRIPTION
The ISSI IS62LV12816BL and IS62LV12816BLL are
high-speed, 2,097,152-bit static RAMs organized as
131,072 words by 16 bits. They are fabricated using
ISSI's high-performance CMOS technology. This highly
reliable process coupled with innovative circuit design
techniques, yields high-performance and low power
consumption devices.
• High-speed access time: 55, 70, 100 ns
• CMOS low power operation
– 120 mW (typical) operating
– 6 µW (typical) CMOS standby
• TTL compatible interface levels
• Single 2.5V-3.0V VCC power supply
WhenCEisHIGH(deselected)orwhenCEislowandbothLBand
UBareHIGH,thedeviceassumesastandbymodeatwhichthe

• Fully static operation: no clock or refresh
required
• Three state outputs

• Data control for upper and lower bytes
• Industrial temperature available
• Available in the 44-pin TSOP (Type II) and
48-pin mini BGA

Notes:
1. Test conditions assume signal transition times of 3 ns or less, timing reference levels of 1.3V, 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 100ꢀ 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).
