AS7C1026B-15TCNTR

Overview

The AS7C1026B-15TCNTR is a 1 Mbit (64K x 16) asynchronous static random access memory manufactured by Alliance Memory, Inc. It operates within a voltage range of 4.5 V to 5.5 V and features a maximum access time of 15 ns. The device utilizes a parallel interface and is housed in a 44-pin TSOP II package designed for surface mount technology. It supports single data rate operations and functions reliably within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Asynchronous operation with fast 15 ns access times
• High-density 1 Mbit storage organized as 64K words by 16 bits
• Standard 5V power supply compatibility

Applications

• General-purpose data buffering in embedded systems
• Cache memory implementation in microcontroller architectures
• Industrial control system data logging

Procurement Notes

Verify the specific suffix TCNTR confirms tape and reel packaging when ordering high volumes. Confirm the 15 ns speed grade matches system timing requirements. Ensure the 44-pin TSOP II footprint aligns with PCB layout constraints. Validate that the commercial temperature range meets operational environmental standards.

Selection Notes

Select this component for applications requiring moderate density SRAM with standard 5V logic levels. The TSOP II package offers a compact solution for space-constrained designs. Consider the 15 ns access speed against processor clock cycles to ensure adequate performance margins for synchronous or asynchronous bus interfaces.

Part Context

This part belongs to the AS7C1026B series of CMOS SRAM devices. It shares architectural similarities with other members like the AS7C1026B-15TCN but differs in packaging format. The TR suffix indicates bulk tape and reel delivery suitable for automated assembly processes.

Replacement Considerations

Direct pin-compatible substitutes include the AS7C1026B-15TCN in tube packaging. Verify electrical specifications match exactly before substitution.
