Overview
The AS7C1025B-15JINTR is a 1 Mbit (128K x 8) asynchronous static random-access memory manufactured by Alliance Memory. It operates within a voltage range of 4.5 V to 5.5 V with a maximum supply current of 90 mA. The device features a 15 ns access time and utilizes a parallel interface. It is housed in a surface-mount SOJ-32 package and supports industrial operating temperatures from -40°C to +85°C. This component is supplied in tape and reel packaging.
Feature Summary
- Asynchronous operation with fast 15 ns access time for efficient data retrieval
- Industrial temperature rating ensuring reliable performance in extreme environments
- Surface-mount SOJ-32 package design optimized for automated assembly processes
Applications
- Industrial control systems requiring robust memory solutions
- Embedded applications operating within wide temperature ranges
- Data acquisition systems utilizing parallel SRAM interfaces
Procurement Notes
Verify the specific suffix JINTR confirms the tape and reel packaging format, as standard variants may use tube packaging. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected variant matches the required 15 ns speed grade and 5V logic levels for system compatibility.
Selection Notes
Select this component when an industrial-grade 1 Mbit SRAM with surface-mount capabilities is required. The 15 ns speed suits high-performance asynchronous applications. Consider the SOJ-32 footprint constraints and verify that the 90 mA active current draw fits within the system power budget. Compare against commercial grade options if temperature requirements are less stringent.
Part Context
This part belongs to the AS7C1025B series of 1 Mbit asynchronous SRAMs. It shares architectural similarities with other members like the AS7C1025B-15JIN but differs in packaging configuration. The series provides a standardized parallel interface solution for general-purpose memory needs across various electronic industries.
Replacement Considerations
AS7C1025B-15JIN serves as a functional equivalent with identical electrical specifications, differing only in tube packaging instead of tape and reel.
