Overview
The AS6C4008A-55STINTR is a 4 Mbit asynchronous static random-access memory organized as 512K x 8 bits. It operates within a supply voltage range of 2.7 V to 3.6 V and features a maximum access time of 55 ns. The device utilizes a parallel interface and is housed in a 32-pin Thin Small Outline Package (TSOP). It supports surface mount installation and functions reliably across an industrial temperature range from -40°C to +85°C.
Feature Summary
- Asynchronous parallel memory architecture for standard data storage applications
- Wide operating voltage compatibility supporting 2.7 V to 3.6 V systems
- Industrial-grade thermal stability for extended operational environments
Applications
- Embedded system data buffering
- Industrial control unit memory expansion
- Consumer electronics internal storage
Procurement Notes
Verify the specific suffix STINTR against official Alliance Memory documentation to confirm package type and reel specifications. Ensure the voltage rating aligns with your target circuit design, as variations exist within the AS6C4008 family. Cross-reference the manufacturer part number directly with authorized distributors to avoid counterfeit components and confirm current availability status.
Selection Notes
Select this component when a 512K x 8 organization is required with a 55 ns access speed. It is suitable for designs needing a 32-pin TSOP footprint. Compare against the AS6C4008-55TINTR if a different packaging format is preferred. Confirm that the 2.7 V to 3.6 V supply range meets the power constraints of the host application before finalizing the bill of materials.
Part Context
This part belongs to the AS6C4008 series of asynchronous SRAMs manufactured by Alliance Memory. The series provides non-volatile-like performance with volatile characteristics. The 'A' designation typically indicates a specific revision or enhanced feature set compared to earlier generations. The STINTR suffix denotes the specific physical package and tape-and-reel shipping configuration.
Replacement Considerations
The AS6C4008-55TIN is a related variant within the same series but may differ in packaging or lifecycle status. Verify pinout compatibility and electrical parameters before substitution. Check for end-of-life notifications on original parts to ensure long-term supply chain stability.
