AS7C31026B-15JCN

Overview

The AS7C31026B-15JCN is a 1 Mbit (64 K x 16) 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 of 75 mA. The device features a parallel interface and offers a typical access time of 15 ns. It is housed in a 44-pin Small Outline J-Lead package designed for surface-mount installation. The component supports commercial temperature operation, functioning reliably between 0°C and +70°C.

Feature Summary

• Provides non-volatile data retention characteristics inherent to SRAM technology without requiring refresh cycles.
• Supports standard parallel bus interfaces for direct connection to microprocessors and digital signal processors.
• Operates on a single 3.3 V power supply rail compatible with modern low-voltage logic families.

Applications

• Embedded systems requiring fast local data storage
• Industrial control units needing reliable memory buffers
• Consumer electronics utilizing 3.3 V logic architectures

Procurement Notes

Verify the specific suffix JCN confirms the SOJ-44 package and commercial temperature grade against your schematic requirements. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design-in reviews account for the humidity sensitivity classification indicated in the datasheet. Validate that the 15 ns access speed meets the timing constraints of your target processor bus.

Selection Notes

Select this component when a 64 K x 16 organization is required within a 44-pin form factor. Choose the JCN variant specifically for its Small Outline J-Lead package geometry suitable for certain PCB layouts. Consider the commercial temperature range if industrial specifications are not mandatory. Compare against TSOP-II alternatives if leadless surface mount is preferred over J-leads.

Part Context

This part belongs to the AS7C31026B series of high-speed asynchronous SRAMs. It serves as a fixed-width memory solution for applications demanding rapid read/write operations. The B-series designation typically indicates specific process improvements or pinout consistency within the manufacturer's portfolio. It complements other density variants in the same family offering different bit organizations.
