AS7C31026B-10TCNTR

Overview

The AS7C31026B-10TCNTR is a 1 Mbit (64K x 16) asynchronous static random-access memory manufactured by Alliance Memory. It operates within a voltage range of 3.0 V to 3.6 V and features a maximum access time of 10 ns. The device utilizes a parallel interface and is housed in a 44-pin TSOP II package suitable for surface-mount technology. It supports single data rate operations and functions reliably across commercial temperatures from 0°C to +70°C, with a maximum supply current of 80 mA.

Feature Summary

• Provides high-speed asynchronous data access with a 10 ns cycle time for efficient system integration.
• Operates on a standard 3.3 V power supply, ensuring compatibility with modern low-voltage logic families.
• Utilizes a compact 44-pin TSOP II surface-mount package to optimize printed circuit board real estate.

Applications

• Embedded systems requiring fast local data storage
• Industrial control units needing reliable volatile memory
• Consumer electronics utilizing 3.3 V logic interfaces

Procurement Notes

Verify the specific suffix TCNTR indicates tape-and-reel packaging when sourcing components. Confirm that the 10 ns speed grade matches the target system timing requirements. Ensure the 3.3 V operating voltage aligns with the design's power rails. Check RoHS compliance status if environmental regulations apply to the manufacturing process.

Selection Notes

Select this component for designs requiring 1 Mbit capacity with a 16-bit word width. The 10 ns access time suits applications demanding rapid data retrieval. The TSOP II package facilitates automated surface-mount assembly processes. Consider the commercial temperature range limits when evaluating environmental exposure during operation.

Part Context

This part belongs to the AS7C31026B series of SRAM devices. It shares architectural similarities with other members like the AS7C31026B-10JCN but differs in packaging and temperature rating. The series offers various speed grades and package options to accommodate diverse embedded memory needs.

Replacement Considerations

Direct substitutes include the AS7C31026B-10JCN for tube packaging or the AS7C31026B-12JCNTR for slower 12 ns performance. Verify pinout compatibility before swapping packages. Ensure voltage and temperature specifications meet the original design constraints.
