DESCRIPTION
The ISSI IS61WV12816DAxx/DBxx and IS64WV12816DBxx
are high-speed, 2,097,152-bit static RAMs organized as
131,072 words by 16 bits. It is fabricated using ISSI's highperformance CMOS technology. This highly reliable process coupled with innovative circuit design techniques,
yields high-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 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 IS61WV12816DAxx/DBxx and IS64WV12816DBxx are
packaged in the JEDEC standard 44-pin TSOP Type II 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.
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. Shaded area product in development

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.
