64K x 16 LOW VOLTAGE,
ULTRA LOW POWER CMOS STATIC RAM
JUNE 2005
FEATURES
DESCRIPTION
• High-speed access time: 45ns, 55ns
The ISSI IS62WV6416ALL/ IS62WV6416BLL are highspeed, 1M bit static RAMs organized as 64K words by 16
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.
• CMOS low power operation:
30 mW (typical) operating
15 µW (typical) CMOS standby
When CS1 is HIGH (deselected) or when CS2 is LOW
(deselected) or when CS1 is LOW, CS2 is HIGH and both
LB and UB are HIGH, the device assumes a standby mode
at which the power dissipation can be reduced down with
CMOS input levels.
• TTL compatible interface levels
• Single power supply
1.7V--2.2V VDD (62WV6416ALL)
2.5V--3.6V VDD (62WV6416BLL)
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. A
data byte allows Upper Byte (UB) and Lower Byte (LB)
access.
• Fully static operation: no clock or refresh
required
• Three state outputs
• Data control for upper and lower bytes
The IS62WV6416ALL and IS62WV6416BLL are packaged
in the JEDEC standard 48-pin mini BGA (6mm x 8mm) and
44-Pin TSOP (TYPE II).
• Industrial temperature available
• 2CS Option Available
• Lead-free available

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