Overview
The AS7C31024B-12JCN 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 and features a maximum access time of 12 ns. The device utilizes a parallel interface and is housed in a 32-pin SOJ package designed for surface-mount technology. It supports single data rate operation and functions reliably across a commercial temperature range from 0°C to +70°C, with a maximum power consumption of 65 mA.
Feature Summary
- Asynchronous SRAM architecture providing fast read access times
- Single voltage operation compatible with 3.3V logic systems
- Surface-mountable 32-pin SOJ package design
Applications
- Embedded memory storage in consumer electronics
- Cache memory buffers in industrial control systems
- Data buffering in telecommunications equipment
Procurement Notes
Verify the specific suffix JCN corresponds to the 32-pin SOJ package configuration when sourcing replacements. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the procurement channel provides valid traceability for the Alliance Memory brand. Check humidity sensitivity levels if the component has been stored outside controlled conditions.
Selection Notes
Select this component for designs requiring 1 Mbit capacity with 12 ns speed at 3.3V. The SOJ-32 form factor suits applications needing surface mount assembly without excessive board space. Compare against TSOP variants if leaded pin requirements differ. Validate that the 65 mA current draw fits the system power budget constraints.
Part Context
This part belongs to the AS7C31024B series of high-speed asynchronous SRAMs. It serves as a non-volatile-free memory solution for temporary data retention in digital circuits. The JCN designation specifically identifies the plastic SOJ package variant offered by Alliance Memory for commercial grade applications.
Replacement Considerations
Direct substitutes include AS7C31024B-12TCN (TSOP-32 package) or AS7C31024B-10JCN (10ns speed). Verify pin compatibility and voltage tolerances before swapping packages.
