AS7C1026B-10TCNTR

Overview

The AS7C1026B-10TCNTR is a 1 Mbit (64K x 16) asynchronous static random-access memory (SRAM) manufactured by Alliance Memory, Inc. It operates with a maximum access time of 10 ns and supports a parallel interface. The device functions within a supply voltage range of 3.0 V to 3.6 V, with a maximum power consumption of 80 mA. It is housed in a 44-pin TSOP II package and is designed for commercial temperature applications.

Feature Summary

• Provides high-speed asynchronous data access with a 10 ns cycle time.
• Utilizes a standard parallel interface for straightforward system integration.
• Operates on a single 5V-compatible power supply rail.

Applications

• Embedded systems requiring fast local data storage
• Industrial control units needing reliable volatile memory
• Consumer electronics with moderate speed requirements

Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging when ordering. Confirm that the commercial temperature grade meets your operational environment requirements. Ensure the 44-pin TSOP II footprint matches your PCB design constraints before finalizing procurement.

Selection Notes

Select this component if a 64K x 16 organization is required rather than byte-wide configurations. Consider the 10 ns speed as sufficient for most general-purpose microcontroller interfaces. Evaluate the TSOP II package size against available board space compared to SOJ or BGA alternatives.

Part Context

This part belongs to the AS7C1026B series of 1 Mbit SRAMs from Alliance Memory. It shares architectural similarities with other variants in the family but differs in package type and operating temperature range. The 'TCN' designation typically denotes commercial temperature and TSOP II packaging.

Replacement Considerations

Check for AS7C1026B-10TIN for tube-packaged equivalents. Verify compatibility with AS7C1026B-10TCN for identical electrical specifications but different packaging formats.
