AS7C31025B-20TJCN

Overview

The AS7C31025B-20TJCN is a 1 Mbit (128K x 8) asynchronous static random access memory manufactured by Alliance Memory. It operates within a supply voltage range of 3.0 V to 3.6 V, with a maximum power consumption current of 70 mA. The device features a parallel interface and offers a typical access time of 20 ns. It is housed in a 32-pin SOJ surface-mount package and supports single data rate operations. The component is rated for commercial operating temperatures between 0°C and +70°C.

Feature Summary

Asynchronous operation with fast data access capabilities
Single voltage supply requirement for simplified system design
Surface-mount packaging for automated assembly integration

Applications

Embedded systems requiring non-volatile-like temporary storage
Industrial control units needing rapid data buffering
Consumer electronics utilizing low-voltage logic interfaces

Procurement Notes

Verify the specific suffix TJCN corresponds to the 32-pin SOJ package configuration rather than TSOP or other variants. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure ESD handling protocols are followed due to moisture sensitivity classification. Cross-reference the exact part number against the latest datasheet revision to validate electrical characteristics and pinout assignments.

Selection Notes

Select this component when a 1 Mbit capacity with 20 ns access speed is required in a 3.3 V environment. The SOJ package is suitable for applications where board space allows for its specific footprint dimensions. Compare against faster access time variants if higher throughput is necessary, or lower voltage parts if system power constraints are stricter than 3.0 V minimums.

Part Context

This part belongs to the AS7C31025B series of high-speed CMOS SRAMs. It shares architectural similarities with other members like the AS7C31025B-10TJCN but differs in access speed specifications. The series is designed for general-purpose memory applications requiring reliable data retention without refresh cycles, distinct from DRAM technologies.

Replacement Considerations

Direct substitutes include the AS7C31025B-10TJCN for faster performance or AS7C31024B-20TJCN for pin-compatible alternatives within the same voltage family. Verify package compatibility and electrical tolerances before swapping.
