AS6C62256A-70SINTR

Overview

The AS6C62256A-70SINTR is a 256-kbit (32K x 8) asynchronous static random-access memory manufactured by Alliance Memory. It operates within a voltage range of 4.5V to 5.5V and features a maximum access time of 70ns. The device utilizes a parallel interface and is housed in a 28-pin Thin Small Outline Package (TSOP). It supports single data rate operations and functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

Asynchronous parallel SRAM architecture for direct interfacing
Industrial-grade operational temperature capability
Single data rate memory organization

Applications

Industrial control systems requiring robust environmental tolerance
Embedded applications with standard logic voltage levels
Data buffering in consumer electronics hardware

Procurement Notes

Verify the specific suffix 'IN' confirms the industrial temperature grade (-40°C to +85°C) rather than commercial variants. Confirm the package type matches the required PCB footprint, as TSOP dimensions differ significantly from DIP or SOP formats. Ensure power supply rails strictly adhere to the 4.5V minimum requirement to prevent malfunction.

Selection Notes

Select this component when an industrial temperature range is mandatory for the application environment. The 70ns access speed suits moderate-speed data processing tasks. Verify that the system design accommodates the 28-pin TSOP surface-mount form factor and provides stable 5V logic power supplies without exceeding the 5.5V maximum limit.

Part Context

This part belongs to the AS6C62256A series of high-density SRAMs. It serves as a non-volatile-free storage solution for microcontrollers and processors. The series offers various speed grades and package options to accommodate different board space and performance requirements in electronic designs.
