AS7C31024B-15TCNTR

Overview

The AS7C31024B-15TCNTR is a 1 Mbit (128K x 8) asynchronous static random-access memory manufactured by Alliance Memory. It operates within a supply voltage range of 4.5 V to 5.5 V, with a maximum power consumption current of 90 mA. The device features a 15 ns access time and utilizes a parallel interface. It is housed in a 32-pin SOJ package designed for surface-mount installation. The component supports single-data-rate operation and functions reliably within a commercial temperature range from 0°C to +70°C.

Feature Summary

• Asynchronous SRAM architecture providing fast data access without external clock synchronization
• Parallel interface supporting standard digital logic connections for high-speed data transfer
• Surface-mount packaging optimized for automated assembly processes

Applications

• Embedded systems requiring non-volatile-like speed with volatile storage characteristics
• Industrial control units operating within commercial temperature environments
• Consumer electronics utilizing 5V logic families

Procurement Notes

Verify the complete part number including the trailing suffix against official manufacturer documentation to confirm specific packaging configurations. Ensure that the selected variant matches the required pinout and electrical specifications for your circuit design. Cross-reference datasheet revisions to confirm compatibility with existing system requirements before finalizing procurement decisions.

Selection Notes

Select this component when a 1 Mbit capacity with 15 ns access speed is required for 5V applications. Consider the SOJ package dimensions for board layout constraints. Verify that the 90 mA maximum current draw aligns with the power supply capabilities of the target system. Confirm humidity sensitivity handling procedures are integrated into the manufacturing workflow.

Part Context

This part belongs to the AS7C1024B series of asynchronous SRAMs. It shares architectural similarities with other members of the family but differs in specific package types and organizational structures. The 15 ns speed grade indicates its performance tier within the broader product line, balancing speed and power consumption for general-purpose memory applications.

Replacement Considerations

Check for direct cross-references such as AS7C1024B-15TJCN or similar variants within the same series. Ensure that any substitute maintains identical voltage ranges, access times, and pin configurations to guarantee functional compatibility without redesigning the host circuit.
