AS7C1025B-12JCN

Overview

The AS7C1025B-12JCN is a 1 Mbit (128 K x 8) asynchronous static random-access memory manufactured by Alliance Memory. It operates with a supply voltage range of 4.5 V to 5.5 V and features a maximum access time of 12 ns. The device utilizes a parallel interface and is housed in a 32-pin Small Outline J-Lead package designed for surface-mount installation. It supports single data rate operations and functions within a commercial temperature range of 0°C to +70°C, with a maximum power supply current of 100 mA.

Feature Summary

• Provides 1 Mbit storage capacity organized as 128K words by 8 bits
• Supports fast asynchronous read access with 12 ns timing
• Operates on standard 5V logic supply levels

Applications

• Embedded systems requiring volatile data retention
• Industrial control equipment logic buffering
• Consumer electronics cache memory applications

Procurement Notes

Verify the specific suffix 'JCN' corresponds to the SOJ-32 package and commercial temperature grade when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design compatibility with 5V logic families due to the specified operating voltage range. Check for moisture sensitivity classification requirements during assembly processing.

Selection Notes

Select this component for designs requiring 5V operation with 12 ns speed. Compare against the AS7C1024B-12JCN variant which shares similar electrical characteristics but may differ in manufacturing revisions or specific pinout configurations. Consider the AS7C31025B series if a 3.3V supply rail is required instead of the standard 5V level.

Part Context

This part belongs to the AS7C1025B family of high-speed SRAM devices from Alliance Memory. The series offers various speed grades and packaging options tailored for different system performance needs. The 12 ns variant represents a balance between speed and power consumption suitable for general-purpose digital logic applications.
