AS7C1026B-12TCN

Overview

The AS7C1026B-12TCN is a 1 Mbit (64K x 16) asynchronous static random-access memory manufactured by Alliance Memory. It operates within a voltage range of 4.5 V to 5.5 V, with a maximum supply current of 100 mA. The device features a 12 ns access time and supports parallel interface communication. Designed for commercial applications, it functions between 0°C and +70°C. The component is housed in a 44-pin TSOP II surface-mount package.

Feature Summary

• Asynchronous operation without clock synchronization requirements
• Single 5V power supply compatibility
• Surface-mount TSOP II packaging for compact integration

Applications

• Embedded systems requiring fast local data storage
• Industrial control units operating in commercial temperature ranges
• Consumer electronics utilizing 5V logic interfaces

Procurement Notes

Verify the specific suffix TCN against official datasheets to confirm the commercial temperature grade and TSOP II package configuration. Ensure voltage requirements align with system design limits. Confirm moisture sensitivity handling procedures are followed during assembly. Cross-reference manufacturer documentation for any recent updates regarding RoHS compliance or pinout definitions before finalizing procurement orders.

Selection Notes

Select this component when a 64K x 16 organization is required with 12 ns speed at 5V. Consider alternative packages like SOJ if leaded connections are preferred. Evaluate thermal constraints as the commercial grade lacks extended temperature support. Compare power consumption metrics against other SRAM families for efficiency optimization in battery-operated designs.

Part Context

This part belongs to the AS7C1026B series of high-speed CMOS SRAMs. It shares architectural similarities with other members but differs in speed grade and package type. The TSOP II variant offers a smaller footprint compared to traditional SOJ packages, facilitating denser PCB layouts while maintaining standard parallel interface compatibility across the family.

Replacement Considerations

AS7C1026B-12TIN provides industrial temperature range (-40°C to +85°C) in the same TSOP II package. AS7C1026B-15TCN offers slower 15 ns access time in the same commercial package. Verify pin compatibility and electrical specifications before substituting.
