DESCRIPTION
The ISSI IS63/64WV1288Dxxx is a very high-speed,
low power, 131,072-word by 8-bit CMOS static RAM.
The IS63/64WV1288DBLL is fabricated using ISSI's
high-performance CMOS technology. This highly reliable
process coupled with innovative circuit design
techniques, yields higher performance and low power
consumption devices.
When CE is HIGH (deselected), the device assumes a
standby mode at which the power dissipation can be reduced down to 25 µW (typical) with CMOS input levels.
The IS63/64WV1288DBLL operates from a single Vdd
power supply. The IS63/64WV1288Dxxx is available in
32-pin TSOP (Type II), 32-pin sTSOP (Type I), 48-Ball
miniBGA (6mm x 8mm) and 32-pin SOJ (300-mil) packages.

3. The internal write time is defined by the overlap of CE LOW 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.

Notes:
1. Test conditions assume signal transition times of 1.5ns or less, timing reference levels of 1.25V, input pulse levels of 0.4V to
Vdd-0.3V 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. 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.

2. I/O will assume the High-Z state if OE > Vih.
