The IS61(64)LPS12832A is organized as 131,072 words by 32 bits. The IS61(64)LPS/VPS12836A is organized as 131,072 words by 36 bits. The IS61(64)LPS/ VPS25618A is organized as 262,144 words by 18 bits. Fabricated with ISSI's advanced CMOS technology, the device integrates a 2-bit burst counter, high-speed SRAM core, and high-drive capability outputs into a single monolithic circuit. All synchronous inputs pass through registers controlled by a positive-edge-triggered single clock input. Write cycles are internally self-timed and are initiated by the rising edge of the clock input. Write cycles can be one to four bytes wide as controlled by the write control inputs. Separate byte enables allow individual bytes to be written. The byte write operation is performed by using the byte write enable (BWE) input combined with one or more individual byte write signals (BWx). In addition, Global Write (GW) is available for writing all bytes at one time, regardless of the byte write controls. Bursts can be initiated with either ADSP (Address Status Processor) or ADSC (Address Status Cache Controller) input pins. Subsequent burst addresses can be generated internally and controlled by the ADV (burst address advance) input pin. The mode pin is used to select the burst sequence order, Linear burst is achieved when this pin is tied LOW. Interleave burst is achieved when this pin is tied HIGH or left floating.

X means “Don’t Care.” H means logic HIGH. L means logic LOW. 2. For WRITE, L means one or more byte write enable signals (BWa-d) and BWE are LOW or GW is LOW. WRITE = H for all BWx, BWE, GW HIGH. 3. BWa enables WRITEs to DQa’s and DQPa. BWb enables WRITEs to DQb’s and DQPb. BWc enables WRITEs to DQc’s and DQPc. BWd enables WRITEs to DQd’s and DQPd. DQPa and DQPb are available on the x18 version. DQPa-DQPd are available on the x36 version. 4. All inputs except OE and ZZ must meet setup and hold times around the rising edge (LOW to HIGH) of CLK. 5. Wait states are inserted by suspending burst. 6. For a WRITE operation following a READ operation, OE must be HIGH before the input data setup time and held HIGH during the input data hold time. 7. This device contains circuitry that will ensure the outputs will be in High-Z during power-up. 8. ADSP LOW always initiates an internal READ at the L-H edge of CLK. A WRITE is performed by setting one or more byte write enable signals and BWE LOW or GW LOW for the subsequent L-H edge of CLK. See WRITE timing diagram for clarification.
