AS7C256A-10TIN

Overview

The AS7C256A-10TIN is a 256Kbit (32K x 8) asynchronous static random-access memory (SRAM) manufactured by Alliance Memory, Inc. It operates within a voltage range of 4.5V to 5.5V and features a maximum access time of 10ns. The device utilizes a parallel interface and is housed in a 28-pin TSOP I surface-mount package. It supports an operating temperature range from -40°C to +85°C, suitable for industrial applications. Maximum supply current is specified at 70mA.

Feature Summary

Asynchronous SRAM architecture providing non-clock-dependent data access
Industrial-grade operational temperature range for robust performance
Surface-mount TSOP I packaging optimized for space-constrained designs

Applications

Industrial control systems requiring reliable volatile memory storage
Embedded systems with strict thermal environment constraints
Data buffering in high-speed parallel communication interfaces

Procurement Notes

Verify the specific suffix 'TIN' confirms the 10ns speed grade and TSOP I package variant. Ensure the design accommodates the 4.5V to 5.5V power supply requirements. Confirm moisture sensitivity level handling procedures are followed during assembly. Cross-reference the manufacturer datasheet for exact pinout definitions and electrical characteristics prior to integration.

Selection Notes

Select this component when a 256Kbit capacity with 10ns access speed is required in a 28-pin surface-mount form factor. It is appropriate for designs needing industrial temperature stability (-40°C to +85°C). Consider the 5V logic compatibility and parallel interface requirements. Evaluate alternative speed grades or packages if voltage or footprint constraints differ.

Part Context

This part belongs to the AS7C256A series of 256Kbit SRAMs from Alliance Memory. The series offers various speed grades and package options to suit different application needs. The AS7C256A-10TIN specifically targets industrial environments with its extended temperature range and standard 5V operation, distinguishing it from commercial variants or lower-speed models.
