AS7C1026B-12JINTR

Overview

The AS7C1026B-12JINTR is a 1 Mbit (64 K x 16) asynchronous static random-access memory manufactured by Alliance Memory. It operates with 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 44-pin SOJ package designed for surface-mount technology. It supports single data rate operation and functions within an industrial temperature range of -40°C to +85°C, with a maximum power consumption of 75 mA.

Feature Summary

• Provides high-speed asynchronous data access with a 12 ns cycle time for efficient system integration.
• Supports 16-bit data organization to facilitate wide-bus microprocessor architectures.
• Operates on a standard 3.3 V power supply for compatibility with low-voltage logic systems.

Applications

• Industrial control systems requiring reliable memory storage under varying environmental conditions.
• Embedded applications utilizing 16-bit microprocessors or digital signal processors.
• Automotive electronics operating within specified industrial temperature ranges.

Procurement Notes

Verify the specific suffix JINTR against official datasheets to confirm the package type and moisture sensitivity level. Ensure the design supports the required 3.3 V supply voltage and 12 ns timing constraints. Confirm availability status as distribution channels may vary. Check RoHS compliance documentation for regulatory adherence before finalizing procurement decisions.

Selection Notes

Select this component when a 16-bit data width is necessary for the target application architecture. The 12 ns speed class suits general-purpose processing tasks without requiring synchronous clocking. Consider the SOJ-44 package dimensions for PCB layout constraints. Verify that the industrial temperature rating aligns with the operational environment requirements of the end product.

Part Context

This part belongs to the AS7C1026B series of 1 Mbit SRAM devices from Alliance Memory. The series offers various speed grades and packaging options to accommodate different design needs.
