DESCRIPTION
The ISSI IS61LV51216 is a high-speed, 8M-bit static RAM
organized as 525,288 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 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 IS61LV51216 is packaged in the JEDEC standard
44-pin TSOP Type II and 48-pin Mini BGA (9mm x 11mm).

Notes:

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.
