Overview
The AS7C31026B-12TIN is a 1 Mbit (64 K x 16) asynchronous static random-access memory manufactured by Alliance Memory. It operates with a supply voltage range of 3.0 V to 3.6 V and features a maximum access time of 12 ns. The device utilizes a parallel interface and is housed in a 44-pin TSOP II surface-mount package. It supports single data rate operations and functions within a commercial temperature range of 0°C to +70°C, with a maximum power consumption of 75 mA.
Feature Summary
- Provides high-speed asynchronous data access with a 12 ns cycle time for efficient system integration.
- Supports 16-bit wide data organization to reduce pin count requirements compared to narrower architectures.
- Operates on a standard 3.3 V power supply for compatibility with modern logic families.
Applications
- Embedded systems requiring fast local data storage
- Industrial control units needing reliable volatile memory
- Consumer electronics utilizing 3.3 V logic interfaces
Procurement Notes
Verify the specific suffix 'TIN' against official datasheets to confirm the TSOP II package and industrial/commercial temperature rating. Ensure the design supports 3.3 V logic levels, as this variant differs from 5 V versions. Confirm humidity sensitivity handling during assembly, as moisture sensitivity is indicated for this component type.
Selection Notes
Select this part when a 16-bit data width is required for memory efficiency. Compare against the AS7C31026B-12JCN if a SOJ package is preferred instead of TSOP II. Verify that the 12 ns speed meets the system timing constraints and that the 3.3 V operating voltage aligns with the target platform's power rails.
Part Context
This component belongs to the AS7C31026B series of 1 Mbit SRAM devices. It shares architectural similarities with other members like the AS7C31025B but offers a wider 16-bit bus width. The series is designed for applications demanding low power consumption and high-speed performance in compact surface-mount form factors.
Replacement Considerations
Check for direct substitutes such as the AS7C31026B-12JCN for package differences or AS7C31026B-12TCN for alternative mounting styles. Ensure electrical parameters match before substitution.
