AS7C1025C-15JINTR

Overview

The AS7C1025C-15JINTR is a 1-Mbit (128K x 8) asynchronous static random-access memory manufactured by Alliance Memory. It operates at a maximum access time of 15 ns and requires a 3.3 V power supply. The device utilizes a parallel interface for data transfer and is housed in a 32-pin Small Outline J-Lead package. Designed for surface-mount technology, it supports industrial temperature ranges from -40°C to +85°C. The component is supplied in tape-and-reel packaging and exhibits moisture sensitivity.

Feature Summary

• Asynchronous operation with fast 15 ns access times for efficient data retrieval
• Single 3.3 V power supply requirement for low-voltage system integration
• Industrial-grade temperature range ensuring reliability in harsh environments
• Surface-mount SOJ-32 package optimized for automated assembly processes

Applications

• Industrial control systems requiring robust memory solutions
• Embedded applications operating within specified voltage and temperature limits
• Data storage buffers in consumer electronics utilizing 3.3 V logic

Procurement Notes

Verify the specific suffix 'IN' indicates industrial temperature range compliance and 'TR' denotes tape-and-reel packaging configuration. Confirm that the 3.3 V operating voltage aligns with target system requirements. Check current lifecycle status as older variants may be obsolete. Ensure handling procedures account for moisture sensitivity classification during soldering.

Selection Notes

Select this component when a 128K x 8 organization is required with 15 ns speed. Choose over 5 V variants if system design mandates 3.3 V operation exclusively. Consider the SOJ-32 footprint constraints against available PCB space. Verify compatibility with existing asynchronous bus architectures before finalizing the design choice.

Part Context

This part belongs to the AS7C1025C series of high-speed SRAMs. It shares architectural similarities with other members like the AS7C1025B but differs in process technology and voltage specifications. The series provides non-volatile-like retention without power while offering rapid read/write capabilities typical of static RAM structures used in cache and buffer applications.

Replacement Considerations

Direct pin-compatible substitutes include the AS7C1025C-15JIN for tube packaging or AS7C1025C-15TJCNTR for commercial temperature reel options. Cross-reference datasheets to confirm voltage tolerance and temperature range matches before substitution.
