DESCRIPTION The ISSI IS61WV51216ALL/BLL and IS64WV51216BLL
are high-speed, 8M-bit static RAMs organized as 512K 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 device is packaged in the JEDEC standard 44-pin TSOP Type II and 48-pin Mini BGA (9mm x 11mm).

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 tSA, t HA, tSD, and tHD 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.
