FUNCTIONAL BLOCK DIAGRAM
DESCRIPTION
The ISSI IS64LV6416L is a high-speed, 1,048,576-bit
static RAM organized as 65,536 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 access times
as fast as 10 ns with low power consumption.
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 IS64LV6416L is packaged in the JEDEC standard
44-pin TSOP-II, and 48-pin mini BGA (6mm x 8mm).
