  • 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

All voltages referenced to V SS (GND). 2. I CC limit shown is for absolute worst case switching of ADDR, ADDR\\, ADDR, etc. 3. I CC is dependent on output loading and cycle rates. 4. This parameter is guaranteed but not tested. 5. Test conditions as specified with the output loading as shown in Fig. 1 unless otherwise noted. tLZCE, tLZWE, tLZOE, t HZCE, tHZOE and tHZWE are specified with CL = 5pF as in Fig. 2. Transition is measured ±200mV from steady state voltage. 7. At any given temperature and voltage condition, tHZCE is less than tLZCE, and tHZWE is less than tLZWE. 8. WE\\ is HIGH for READ cycle. 9. Device is continuously selected. Chip enables and output enables are held in their active state. 10. Address valid prior to, or coincident with, latest occurring chip enable. 11. tRC = Read Cycle Time. 12. Chip enable and write enable can initiate and terminate a WRITE cycle. 13. Output enable (OE\\) is inactive (HIGH). 14. Output enable (OE\\) is active (LOW). 15. ASI does not warrant functionality nor reliability of any product in which the junction temperature exceeds 150°C. Care should be taken to limit power to acceptable levels.
