AS7C4098A-15TCN

Memory IC Overview

The AS7C4098A-15TCN is a 4 Mbit (256K x 16) asynchronous static random-access memory manufactured by Alliance Memory. It operates within a 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 44-pin TSOP-II surface-mount package. It supports single data rate operations and is rated for commercial temperature ranges from 0°C to +70°C, with a maximum supply current of 170 mA.

Memory IC Feature Summary

• Provides non-volatile-like retention characteristics inherent to SRAM technology without requiring refresh cycles.
• Supports high-speed parallel data transfer via dedicated address and data lines.
• Designed for surface-mount assembly using a compact 44-pin thin-shrink small-outline package.

Memory IC Applications

• Embedded systems requiring fast local data storage
• Industrial control units needing reliable volatile memory
• Consumer electronics with space-constrained PCB layouts

Memory IC Procurement Notes

Verify the specific suffix TCN confirms the TSOP-II-44 package and commercial temperature grade. Ensure the 3.3V logic compatibility matches the target system voltage. Confirm RoHS compliance status through official manufacturer documentation before integration into regulated assemblies.

Memory IC Selection Notes

Select this component when a 256K x 16 organization is required with 15 ns speed. Compare against AS7C4098A-10 variants for faster access or AS7C32098A for lower density. Ensure the 44-pin TSOP-II footprint fits the design constraints.

Memory IC Part Context

This part belongs to the AS7C34098A series of 4 Mbit asynchronous SRAMs. It shares architectural similarities with other members like AS7C4098A-15JCN but differs in package type and operating temperature specifications. The series targets general-purpose memory applications requiring moderate speed and density.

Memory IC Replacement Considerations

Direct pin-compatible substitutes include AS7C4098A-15JCN (SOJ package) or AS7C4098A-10TCN (faster speed). Verify electrical parameters match exactly before substitution.
