AS7C31025B-12TJINTR

Overview

The AS7C31025B-12TJINTR is a 1 Mbit (128 K x 8) 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 supports a maximum power consumption current of 65 mA and functions across an industrial temperature range from -40 °C to +85 °C. It utilizes a parallel interface and is housed in a surface-mount SOJ-32 package, supplied in reel packaging.

Feature Summary

• Provides high-speed asynchronous data access with a 12 ns cycle time for efficient system integration.
• Operates on a single 3.3 V power supply rail, ensuring compatibility with standard logic levels.
• Designed for industrial environments with extended temperature tolerance ranging from -40 °C to +85 °C.

Applications

• Industrial control systems requiring reliable non-volatile-like temporary storage
• Embedded applications utilizing 3.3 V logic families
• Data buffering in high-speed parallel communication interfaces

Procurement Notes

Verify the specific suffix TJINTR confirms the SOJ-32 package and tape-and-reel delivery format against official datasheets. Confirm that the industrial temperature grade (-40°C to +85°C) aligns with your environmental requirements. Ensure voltage specifications match your 3.3 V system design constraints before finalizing procurement orders.

Selection Notes

Select this component when a 128 K x 8 organization is required alongside strict 3.3 V operation limits. The SOJ-32 form factor suits space-constrained surface-mount designs. Consider the 12 ns access speed relative to your processor clock cycles to ensure timing compliance without additional wait states.

Part Context

This part belongs to the AS7C31025B series of fast asynchronous SRAMs. It represents a 3.3 V variant optimized for lower power consumption compared to older 5 V generations. The series maintains pin-out compatibility within its family while offering improved performance metrics suitable for modern embedded architectures.

Replacement Considerations

Check for AS7C31025B-12TCN or AS7C31025B-12JCN if commercial temperature grades suffice. Verify package equivalence for TSOP or SOJ variants if lead-free processing is mandatory.
