Part Number : AS5C4009LL
Function : 512K x 8 SRAM - Ultra Low Power
Package : TSSOP 32 Pin Type
Maker : Austin Semiconductor
The AS5C4009LL is organized as 524,288 x 8 SRAM utilizing a special ultra low power design process. ASI’s pinout adheres to the JEDEC standard for pinout on 4 megabit SRAMs. The evolutionary 32 pin version allows for easy upgrades from the 1 meg SRAM design.
For flexibility in memory applications, ASI offers chip enable (CE) and output enable (OE) capabilities. These features can place the outputs in High-Z for additional flexibility in system design.
This devices operates from a single +5V power supply and all inputs and outputs are fully TTL-compatible.
• Ultra Low Power with 2V Data Retention (0.2mW MAX worst case Power-down standby)
• Fully Static, No Clocks
• Single +5V ±10% power supply
• Easy memory expansion with CE\ and OE\ options
• All inputs and outputs are TTL-compatible
