FEATURES
DESCRIPTION
The ISSI IS61LV6416/IS61LV6416L is a high-speed,
1,048,576-bitstaticRAMorganizedas65,536wordsby16
bits. It is fabricated using ISSI's high-performance CMOS
technology. This highly reliable process coupled with
innovative circuit design techniques, yields access times
as fast as 8 ns with low power consumption.
• High-speed access time: 8, 10, 12 ns
• CMOS low power operation
— 61LV6416:
75 mW (typical) operating current
0.5 mW (typical) standby current
— 61LV6416L:
When CE is HIGH (deselected), the device assumes a
standby mode at which the power dissipation can be
reduced down with CMOS input levels.
65 mW (typical) operating current
50 µW (typical) standby current
• TTL compatible interface levels
• Single 3.3V power supply
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.
• Fully static operation: no clock or refresh
required
• Three state outputs

standard 44-pin 400-mil SOJ, 44-pin TSOP-II, and 48-pin
mini BGA (6mm x 8mm).
• Data control for upper and lower bytes
• Industrial temperature available
• Lead-free available
