Overview
The AS7C31024B-12TCN is a 1 Mbit (128K x 8) asynchronous static random access memory manufactured by Alliance Memory. It operates at a maximum access time of 12 ns and requires a supply voltage between 3 V and 3.6 V, with a maximum power consumption of 65 mA. The device utilizes a parallel interface and is housed in a 32-pin TSOP II package suitable for surface mount technology. It supports single data rate storage and functions within a commercial temperature range of 0°C to +70°C.
Feature Summary
- Provides fast asynchronous data access with a 12 ns cycle time for high-performance applications.
- Operates on a standard 3.3 V power supply with low current consumption characteristics.
- Utilizes CMOS technology to ensure high reliability and compatibility with standard logic families.
Applications
- Battery backup nonvolatile memory systems
- Fast asynchronous data buffering
- Embedded system cache memory
Procurement Notes
Verify the specific suffix TCN confirms the TSOP II package and commercial temperature grade against official datasheets. Confirm RoHS compliance status through manufacturer documentation prior to integration. Ensure design-in requirements match the 3.3 V operating voltage and 12 ns timing specifications exactly.
Selection Notes
Select this component when a 128K x 8 organization is required with 12 ns speed in a compact 32-pin surface mount package. Compare against the AS7C31024B-12JCN if an SOJ package or industrial temperature range is preferred instead. Validate that the 3.3 V logic levels align with the target system architecture.
Part Context
This part belongs to the AS7C31024B series of 1 Mbit SRAM devices from Alliance Memory. The series offers various speed grades and packaging options including TSOP and SOJ formats. It serves as a direct replacement for legacy 1 Mbit SRAM components requiring similar pinouts and electrical characteristics.
Replacement Considerations
The AS7C31024B-12JCN is a documented alternative offering identical electrical performance but in an SOJ-32 package. Verify pinout compatibility and thermal requirements when substituting between TSOP and SOJ form factors.
