AS7C31026B-12JINTR

Overview

The AS7C31026B-12JINTR is a 1 Mbit (64 K x 16) asynchronous static random-access memory manufactured by Alliance Memory. It operates within a supply voltage range of 3 V to 3.6 V and features a maximum access time of 12 ns. The device utilizes a parallel interface and is housed in a surface-mount SOJ-44 package. It supports single data rate storage and functions within an operating temperature range of 0°C to +70°C, with a maximum power supply current of 75 mA.

Feature Summary

• Provides high-speed asynchronous data access with a 12 ns cycle time for efficient system integration.
• Supports wide 16-bit data organization to reduce pin count requirements compared to narrower architectures.
• Operates on a standard 3.3 V power supply rail for compatibility with modern logic families.

Applications

• High-performance embedded systems requiring fast local data buffering
• Industrial control units needing reliable volatile memory storage
• Telecommunications equipment utilizing 3.3 V logic interfaces

Procurement Notes

Verify the specific suffix JINTR against official datasheets to confirm the reel packaging configuration and moisture sensitivity level. Ensure the ordering quantity aligns with the manufacturer's specified minimum order multiples for tape-and-reel delivery. Confirm RoHS compliance status through the latest environmental documentation provided by Alliance Memory prior to final procurement decisions.

Selection Notes

Select this component when a 16-bit data width is required alongside a 3.3 V operating voltage. The 12 ns speed class suits applications demanding rapid random access without complex clocking schemes. Compare the SOJ-44 footprint against available board space and ensure thermal management meets the commercial temperature range specifications.
