AS7C256A-15TINTR

Overview

The AS7C256A-15TINTR is a 256-kbit (32K x 8) asynchronous static random-access memory (SRAM) manufactured by Alliance Memory. It operates within a supply voltage range of 4.5V to 5.5V and features a maximum access time of 15ns. The device utilizes a parallel interface and is housed in a 28-pin TSOP I surface-mount package. It supports single data rate (SDR) operation and is rated for commercial temperature ranges, typically spanning from 0°C to +70°C. The component is supplied in tape and reel packaging for automated assembly processes.

Feature Summary

Asynchronous SRAM architecture with parallel interface
Surface-mount TSOP I package configuration
Single data rate (SDR) memory organization

Applications

Embedded systems requiring volatile data storage
Industrial control units
Consumer electronics devices

Procurement Notes

Verify the specific suffix 'TR' confirms tape-and-reel packaging rather than tray distribution. Confirm the operating temperature grade matches the target application environment, as commercial variants may differ from industrial ratings. Ensure the 5V logic compatibility aligns with the system bus requirements before integration.

Selection Notes

Select this component when a 32K x 8 memory organization is required with 15ns access speed. The TSOP I package suits space-constrained surface-mount designs. Verify that the 5V supply voltage and commercial temperature range meet the system specifications compared to lower-voltage or industrial-grade alternatives.

Part Context

This part belongs to the AS7C256A series of high-speed CMOS static RAMs. It shares the same memory density and core functionality with other variants in the family but differs in package type and delivery format. The 'TR' suffix specifically denotes the tape-and-reel packaging method used for high-volume automated manufacturing.
