These SRAMs are fabricated using double-layer metal, double-layer polysilicon technology. For flexibility in high-speed memory applications, Austin Semiconductor offers chip enable (CE\\) and output enable (OE\\) capability. These enhancements can place the outputs in High-Z for additional flexibility in system design. Writing to these devices is accomplished when write enable (WE\\) and CE\\ inputs are both LOW. Reading is accomplished when WE\\ remains HIGH and CE\\ and OE\\ go LOW. The device offers a reduced power standby mode when disabled. This allows system designs to achieve low standby power requirements. The “L” version provides a battery backup/low voltage data retention mode, offering 2mW maximum power dissipation at 2 volts. All devices operate from a single +5V power supply and all inputs and outputs are fully TTL compatible. 4 3 2 1 32 31 30 A12 A14 NC V CC WE\\ A13 14 15 16 17 18 19 20DQ2 DQ3 V SS NC DQ4 DQ5 DQ6 NC DQ1 A11 NC OE\\ A10 CE\\ DQ8 DQ7 3 2 1 28 27 A12 A14 V CC WE\\ 13 14 15 16 17 DQ3 VSS DQ4 DQ5 DQ6 DQ1 DQ2 A13 A11 OE\\ A10 CE\\ DQ8 DQ7 A14 1 28 VCC A12 2 27 WE\\ A7 3 26 A13 A6 4 25 A8 A5 5 24 A9 A4 6 23 A11 A3 7 22 OE\\ A2 8 21 A10 A1 9 20 CE\\ A0 10 19 DQ8 DQ1 11 18 DQ7 DQ2 12 17 DQ6 DQ3 13 16 DQ5 VSS 14 15 DQ4 32K x 8 SRAM SRAM MEMORY ARRAY For more products and information please visit our web site at www.austinsemiconductor.com A14 1 28 VCC A12 2 27 WE\\ A7 3 26 A13 A6 4 25 A8 A5 5 24 A9 A4 6 23 A11 A3 7 22 OE\\ A2 8 21 A10 A1 9 20 CE\\ A0 10 19 DQ8 DQ1 11 18 DQ7 DQ2 12 17 DQ6 DQ3 13 16 DQ5 V SS 14 15 DQ4
