DECEMBER 2008
DESCRIPTION
The ISSI IS62WV1288ALL / IS62/65WV1288BLL are high-speed, 1M bit static RAMs organized as 128K words
by 8 bits. It is fabricated using ISSI's high-performance
CMOS technology. This highly reliable process coupled
with innovative circuit design techniques, yields highperformance and low power consumption devices.
When CS1 is HIGH (deselected) or when CS2 is low
(deselected), the device assumes a standby mode at
which the power dissipation can be reduced down with
CMOS input levels.
• Single power supply: 1.65V--2.2V Vdd (62WV1288ALL)
2.5V--3.6V Vdd (62WV1288BLL/ 65WV1288BLL)
• Fully static operation: no clock or refresh
required
• Three state outputs
• Automotive and Industrial temperatures available
Easy memory expansion is provided by using Chip Enable
and Output Enable inputs. The active LOW Write Enable
(WE) controls both writing and reading of the memory.
The IS62WV1288ALL and IS62/65WV1288BLL are
packaged in the JEDEC standard 32-pin TSOP (TYPEI),
sTSOP (TYPEI), SOP, and 36-pin mini BGA.
• Lead-free available

2. The internal write time is defined by the overlap of CS1 LOW, CS2 HIGH, 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.
