AS6C62256A-70SIN

Overview

The AS6C62256A-70SIN is a 256-kbit (32K x 8) asynchronous static random-access memory (SRAM) manufactured by Alliance Memory. It features a parallel interface with a maximum access time of 70 ns and operates within a supply voltage range of 4.5 V to 5.5 V. The component utilizes a 28-pin Small Outline Package (SOP) for surface-mount installation, supporting commercial temperature operation from 0°C to +70°C.

Feature Summary

• Asynchronous parallel SRAM architecture providing non-clock-dependent data access
• Single power supply operation compatible with standard 5V logic systems
• Surface-mount SOP-28 package design for compact circuit board integration

Applications

• General-purpose volatile data storage in embedded systems
• Cache memory buffers for microcontroller applications
• Industrial control system data logging

Procurement Notes

Verify the specific suffix 'SIN' against official datasheets to confirm pinout compatibility and electrical characteristics. Ensure the selected variant matches the required operating temperature range and voltage specifications for the target application environment before finalizing procurement.

Selection Notes

Select this component when a 256-kbit capacity is required with a 70 ns access speed. It is suitable for designs needing a 5V supply and surface-mount packaging. Compare against other AS6C62256 variants if lower access times or different voltage ranges are necessary.

Part Context

This part belongs to the AS6C62256 series of high-speed CMOS asynchronous SRAMs. The series offers various access speeds and package options, including through-hole and surface-mount configurations, catering to diverse memory requirements in consumer and industrial electronics.

Replacement Considerations

Compatible substitutes include the AS6C62256-70PCN (PDIP package) and AS6C62256-70STIN (TSOP package). Verify pin compatibility and electrical parameters before substitution.
