AS5LC512K8 Rev. 1.0 7/02 Austin Semiconductor, Inc. reserves the right to change products or specifications without notice. 1 FEATURES • Ultra High Speed Asynchronous Operation • Fully Static, No Clocks • Multiple center power and ground pins for improved noise immunity • Easy memory expansion with CE\ and OE\ options • All inputs and outputs are TTL-compatible • Single +3.3V Power Supply +/- 0.3% • Data Retention Functionality Testing • Cost Efficient Plastic Packaging • Extended Testing Over -55ºC to +125ºC for plastics OPTIONS MARKING • Timing 12ns access -12 15ns access -15 20ns access -20 • Operating Temperature Ranges Military (-55oC to +125oC) XT Industrial (-40oC to +85oC) IT • Package(s) Ceramic Flatpack F No. 307 Plastic SOJ (400 mils wide) DJ Ceramic LCC EC No. 210 • 2V data retention/low power L PIN ASSIGNMENT (Top View) 36-Pin PSOJ (DJ) 36-Pin CLCC (EC) GENERAL DESCRIPTION The AS5LC512K8 is a 3.3V high speed SRAM. It offers flexibility in high-speed memory applications, with chip enable (CE\) and output enable (OE\) capabilities. These features 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. As a option, the device can be supplied offering a reduced power standby mode, allowing system designers to meet low standby power requirements. This device operates from a single +3.3V power supply and all inputs and outputs are fully TTL-compatible. The AS5LC512K8DJ offers the convenience and reliability of the AS5LC512K8 SRAM and has the cost advantage of a plastic encapsulation. 36-Pin Flat Pack (F) AVAILABLE AS MILITARY SPECIFICATIONS •MIL-STD-883 for Ceramic •Extended Temperature Plastic (COTS) 512K x 8 SRAM 3.3 VOLT HIGH SPEED SRAM with CENTER POWER PINOUT For more products and information please visit our web site at www.austinsemiconductor.com |
