S26KS256SDPBHB020

Memory IC Overview

The S26KS256SDPBHB020 is a 256 Mbit HyperFlash NOR memory device from the KS-S series, manufactured by Infineon Technologies (formerly Spansion). It features an x8 bus width and operates within a voltage range of 1.7 V to 1.95 V, typically at 1.8 V. The component supports HYPERBUS interface with an interface frequency of 166 MHz in DDR mode, achieving an interface bandwidth of 333 MByte/s. Initial access time is specified at 96 ns. It is designed for industrial quality grades, functioning between -40 °C and 105 °C, and utilizes a 24-ball FBGA package with Sn/Ag/Cu lead ball surfaces.

Memory IC Feature Summary

• Supports HYPERBUS interface protocol for high-speed data transfer
• Industrial temperature grade operation up to 105 °C
• Low voltage operation compatible with 1.8 V systems
• Automotive qualification compliant with AEC-Q100 standards

Memory IC Applications

• Industrial control systems requiring robust non-volatile storage
• Automotive infotainment and instrument cluster firmware storage
• Network infrastructure equipment boot code storage
• Consumer electronics requiring fast random read access

Memory IC Procurement Notes

Verify the manufacturer designation carefully, as this component originates from Infineon Technologies following the acquisition of Spansion's memory business. Confirm the specific suffix HB020 corresponds to the required industrial temperature range and package variant. Ensure compatibility with the host system's 1.8 V power supply rails and HYPERBUS controller capabilities before integration.

Memory IC Selection Notes

Select this part when a balance of high read speed and moderate density is required for code execution or data logging. The KS-S series offers improved performance over standard SPI NOR flash while maintaining pin compatibility with legacy parallel interfaces. Consider the 24-ball FBGA footprint constraints and thermal management requirements for industrial environments during PCB layout design.

Memory IC Part Context

This component belongs to the S26KS256S family of HyperFlash memories, which are optimized for applications demanding faster random read access than traditional SPI NOR devices. The KS variant specifically targets industrial and automotive markets, offering enhanced reliability and extended temperature ranges compared to commercial-grade counterparts. It serves as a drop-in replacement for certain older parallel NOR solutions where higher throughput is necessary.

Memory IC Replacement Considerations

Direct substitutes include other members of the S26KS256S family, such as S26KS256SDPBHV020 or S26KS256SDPBHI020, depending on the required temperature grade and packaging specifications. Verify that any alternative maintains the same HYPERBUS interface timing and electrical characteristics to ensure functional compatibility without hardware redesign.
