It is organized as 131,072 words by 32 bits or 36 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 from one to four bytes wide as controlled by the write control inputs. Separate byte enables allow individual bytes to be written. BW1 controls DQa, BW2 controls DQb, BW3 controls DQc, BW4 controls DQd, conditioned by BWE being LOW. A LOW on GW input would cause all bytes to be written. 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.

This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability. 2. This device contains circuitry to protect the inputs against damage due to high static voltages or electric fields; however, precautions may be taken to avoid application of any voltage higher than maximum rated voltages to this high-impedance circuit. 3. This device contains circuitry that will ensure the output devices are in High-Z at power up. 6 Integrated Silicon Solution, Inc. -- 1-800-379-4774 PRELIMINARY INFORMATION Rev. 00A 05/28/2001 IS61LF12832 IS61LF12836 ISSI (R) OPERATING RANGE Range Ambient Temperature VCC VCCQ 0C to +70C -40C to +85C 3.3V, +10%, -5% 3.3V, +10%, -5% 2.5V +5%V 2.5V +5%V Commercial Industrial DC ELECTRICAL CHARACTERISTICS (Over Operating Range) Symbol Parameter Test Conditions Min.
