AS7C31025C-12JINTR

Overview

The AS7C31025C-12JINTR is a 1 Mbit (128K x 8) asynchronous static random-access memory manufactured by Alliance Memory. It operates within a supply voltage range of 3.0 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 32-pin SOJ package suitable for surface-mount technology. It supports single data rate operation and functions reliably across an industrial temperature range from -40°C to +85°C, with a maximum power consumption of 150 mA.

Feature Summary

• Asynchronous parallel interface for direct system integration
• Industrial-grade operational temperature stability
• Surface-mount compatible 32-pin SOJ packaging

Applications

• Industrial control systems requiring robust memory storage
• Embedded applications operating in extreme temperatures
• Data buffering in high-speed digital circuits

Procurement Notes

Verify the specific suffix JINTR against official datasheets to confirm package type and tape-and-reel configuration. Confirm RoHS compliance status through manufacturer documentation before procurement. Check current lifecycle status as components may be discontinued or subject to limited availability constraints.

Selection Notes

Select this component when a 128K x 8 organization is required with 12 ns speed at 3.3V logic levels. Ensure the design accommodates the 32-pin SOJ footprint and SMD mounting requirements. Verify that the 150 mA maximum current draw fits within the system's power budget and thermal management capabilities.

Part Context

This part belongs to the AS7C31025C series of fast asynchronous SRAMs. It shares architectural similarities with other members like the AS7C31025B but differs in speed grade and voltage specifications. The 'C' designation typically indicates specific process technology optimizations compared to older generations.

Replacement Considerations

AS7C31025C-12TJINTR: Same capacity and speed, different package variant.
