AS7C31026B-15TIN

Overview

The AS7C31026B-15TIN 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 15 ns. The device utilizes a parallel interface and is housed in a TSOP-II-44 surface-mount package. 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 70 mA.

Feature Summary

• Provides high-speed asynchronous data access with a 15 ns cycle time for efficient system integration.
• Operates on a low-voltage 3.3 V power supply to support energy-efficient designs.
• Designed for industrial environments with extended temperature tolerance from -40°C to +85°C.
• Utilizes a compact TSOP-II-44 surface-mount package for space-constrained applications.

Applications

• Industrial control systems requiring reliable memory under varying thermal conditions
• Embedded computing devices utilizing 3.3 V logic levels
• Data acquisition modules needing fast asynchronous read/write capabilities

Procurement Notes

Verify the specific suffix TIN indicates the TSOP-II-44 package and tray packaging configuration before ordering. Confirm that the 3.3 V operating voltage aligns with the target system design, as this component is not compatible with 5 V logic interfaces. Check current availability status as supply may be restricted or subject to long lead times due to manufacturing constraints.

Selection Notes

Select this component when a 64 k x 16 organization is required alongside strict 3.3 V power constraints. Compare against the AS7C31026B-12JCNTR if faster 12 ns access is needed, noting the trade-off in speed versus potential cost or availability differences. Ensure the PCB layout accommodates the TSOP-II-44 footprint and that the application environment stays within the specified -40°C to +85°C operational limits.

Part Context

This part belongs to the AS7C31026B series of 1 Mbit SRAMs from Alliance Memory. It shares architectural similarities with other members like the AS7C31026B-12JCNTR but differs in speed grade and package type. The series is designed for general-purpose memory applications where non-volatile storage is unnecessary, offering rapid data retention while powered.

Replacement Considerations

The AS7C31026B-12JCNTR serves as a functional substitute with identical pinout and capacity but offers a faster 12 ns access time. Verify compatibility with existing circuit timing requirements when considering this alternative.
