AS7C1026B-10TCN

Overview

The AS7C1026B-10TCN is a 1 Mbit asynchronous static random access memory (SRAM) manufactured by Alliance Memory. It features a storage organization of 128K x 8 bits and operates with a maximum access time of 10 ns. The device supports a parallel interface and functions within a supply voltage range of 3 V to 3.6 V, with a maximum power consumption of 70 mA. It is housed in a 32-pin TSOP I package suitable for surface mount technology. The component is rated for commercial operating temperatures between 0°C and +70°C.

Feature Summary

• Provides high-speed data access with a 10 ns cycle time for efficient system performance.
• Operates on a single 3.3 V power supply to simplify circuit design.
• Utilizes a compact 32-pin TSOP I surface-mount package for space-constrained applications.

Applications

• Embedded systems requiring fast local data storage
• Industrial control equipment
• Consumer electronics devices

Procurement Notes

Verify the specific suffix TCN confirms the 32-pin TSOP I package and commercial temperature grade. Ensure the 128K x 8 organization matches the target design requirements rather than the 64K x 16 variants found in other series members. Confirm RoHS compliance status through official documentation before integration.

Selection Notes

Select this part when a 1 Mbit capacity with 8-bit word width is required. The 10 ns speed class suits general-purpose processing tasks. Compare against 5V variants if system voltage differs. Verify pin compatibility with existing footprints as TSOP dimensions vary by manufacturer.

Part Context

This component belongs to the AS7C1026B family of asynchronous SRAMs. While related models like the AS7C31024B share similar speed grades, they differ in organization and package type. The AS7C1026B series generally offers 1 Mbit density, but specific bit-width configurations depend on the exact model suffix.

Replacement Considerations

Check for direct cross-references from other manufacturers offering identical 128K x 8, 10 ns, 3.3V specifications in a 32-pin TSOP. Verify electrical characteristics match exactly to ensure functional equivalence without redesign.
