AS7C1026B-20TCN

Overview

The AS7C1026B-20TCN is a 1 Mbit (64 K x 16) asynchronous static random-access memory manufactured by Alliance Memory. It operates with a maximum access time of 20 ns and supports a parallel interface. The device functions within a supply voltage range of 4.5 V to 5.5 V, with a maximum power consumption of 80 mA. It is designed for surface-mount installation in a 44-pin TSOP II package. The component supports an industrial operating temperature range from -40°C to +85°C.

Feature Summary

• Asynchronous operation without clock synchronization requirements
• High-speed data access capabilities for system integration
• Industrial-grade thermal stability for demanding environments

Applications

• Industrial control systems requiring reliable data storage
• Embedded applications utilizing parallel memory interfaces
• Consumer electronics operating under standard voltage conditions

Procurement Notes

Verify the specific suffix TCN confirms the TSOP II package and commercial/industrial temperature rating as documented. Confirm RoHS compliance status through official manufacturer declarations prior to procurement. Ensure the ordering quantity aligns with distributor packaging constraints. Validate that the 20 ns speed grade matches the target system timing requirements exactly.

Selection Notes

Select this component when a 64 K x 16 organization is required for 1 Mbit capacity designs. Choose this part for applications needing 5V logic compatibility with low power consumption characteristics. Consider the TSOP II form factor for space-constrained surface-mount layouts. Verify that the 20 ns access time satisfies the system's maximum cycle time specifications.

Part Context

This SRAM belongs to the AS7C1026B series, representing a generation of high-density static memory solutions. The series provides non-volatile-like retention properties for volatile memory architectures. It serves as a bridge between older parallel memory standards and modern embedded processing needs.

Replacement Considerations

Check for AS7C1026B-20TIN or AS7C1026B-20JIN for alternative pin-compatible options with different packaging or temperature grades. Verify electrical parameter equivalence before substitution.
