S26KS256SDGBHV030

Memory IC Overview

The S26KS256SDGBHV030 is a 256 Mbit (32 M x 8) HyperFlash NOR memory device manufactured by Infineon Technologies, formerly Spansion. It operates with a 1.8V supply voltage and supports clock frequencies up to 133 MHz. The component utilizes a synchronous parallel interface within a 24-pin FBGA package measuring 6x8 mm. It features an initial random read access time of 96 ns and is designed for automotive applications, meeting AEC-Q100 standards with an operating temperature range from -40°C to +105°C.

Memory IC Feature Summary

• Supports HyperBus interface for high-speed data transfer using a single-ended clock and differential clock options.
• Delivers sustained read throughput via Double-Data Rate (DDR) architecture enabling two data transfers per clock cycle.
• Complies with AEC-Q100 automotive qualification standards for reliability in demanding environments.

Memory IC Applications

• Automotive infotainment systems requiring fast boot times
• Telematics control units needing rapid code execution
• Advanced driver-assistance systems (ADAS) storing calibration data

Memory IC Procurement Notes

Verify the manufacturer designation as Infineon Technologies, which acquired Spansion, when sourcing this component. Confirm the specific suffix HV indicates the extended industrial/automotive temperature grade. Ensure the package type matches the required 24-FBGA footprint on the target PCB layout. Check for RoHS compliance documentation relevant to the manufacturing date code.

Memory IC Selection Notes

Select this part when a synchronous parallel interface is preferred over SPI for higher bandwidth requirements. Compare against the S26KL series if lower power consumption at reduced clock speeds is acceptable. Consider the 256 Mbit density relative to system memory constraints. Verify that the 1.8V I/O logic levels are compatible with the host microcontroller or processor.

Memory IC Part Context

This device belongs to the S26KS family of HyperFlash memories, designed to replace traditional parallel NOR flash in high-performance embedded applications. It offers faster boot times and improved read performance compared to asynchronous counterparts. The family includes variants with different densities and voltage options, catering to diverse automotive and industrial storage needs.

Memory IC Replacement Considerations

Direct substitutes include other S26KS256 variants with compatible pinouts and electrical characteristics. Verify that any replacement maintains the same HyperBus protocol support and automotive qualification status. Cross-reference package dimensions to ensure mechanical compatibility without redesigning the board.
