AS7C31024B-12TJCN

Overview

The AS7C31024B-12TJCN 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 storage and functions reliably across a commercial temperature range from 0°C to +70°C, with a maximum power consumption of 65 mA.

Feature Summary

Provides non-volatile-like high-speed data retention through asynchronous SRAM architecture
Supports standard parallel data bus interfaces for direct microcontroller integration
Operates at low voltage levels suitable for modern 3.3V logic systems

Applications

Embedded system data buffering
Cache memory implementation in industrial controllers
Data storage in consumer electronics devices

Procurement Notes

Verify the specific suffix TJCN corresponds to the SOJ-32 package configuration when sourcing replacements. Confirm that the 3.3V operating voltage aligns with the target circuit design requirements. Ensure compatibility with existing PCB footprints for 32-pin small outline J-leads. Check RoHS compliance documentation if environmental regulations apply to the final assembly process.

Selection Notes

Select this component when a 12 ns access speed is required for 1 Mbit capacity in a 3.3V environment. The SOJ-32 package offers a compact form factor suitable for space-constrained designs. Compare against TSOP variants if leadless surface mounting is preferred over J-leads. Consider the 65 mA current draw for power budget calculations in battery-operated applications.

Part Context

This part belongs to the AS7C31024B series of high-speed asynchronous SRAMs. It shares architectural similarities with other members like the AS7C31024B-12JCN but differs in package type. The series is designed for general-purpose memory applications requiring fast read/write cycles without complex control protocols.
