AS5C4009LL datasheet



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.

SRAM stands for Static Random Access Memory. It is a type of computer memory that is commonly used as cache memory for the processor. SRAM is a volatile memory, which means that it requires a constant supply of power to maintain the data stored in it. When power is turned off, the data in SRAM is lost.
