S26KS128SDGBHI030

Memory IC Overview

The S26KS128SDGBHI030 is a 128 Mbit (16 M x 8) HyperFlash NOR memory device manufactured by Spansion. It operates with a supply voltage range of 1.7 V to 1.95 V and features a synchronous interface supporting up to 166 MHz clock rates. The component provides an initial random read access time of 96 ns and delivers sustained read throughput of up to 333 MB/s at the specified voltage. It utilizes a 24-pin FBGA package measuring 6x8 mm, designed for high-speed embedded applications requiring low power consumption and fast data retrieval.

Memory IC Feature Summary

• Enables simultaneous read and write operations without bus contention
• Features differential clock signaling for improved signal integrity at high frequencies
• Includes hardware-based security mechanisms for code protection

Memory IC Applications

• Boot code storage in mobile devices and IoT gateways
• Firmware storage for baseband processors and application processors
• High-performance embedded systems requiring fast boot times
• Automotive infotainment and telematics control units

Memory IC Procurement Notes

Verify the manufacturer designation as Spansion or its successor entities, noting corporate acquisitions may affect branding on datasheets. Confirm the specific suffix 'H' corresponds to the correct temperature grade and package variant. Ensure compatibility with host controllers supporting the HyperBus protocol. Check for RoHS compliance status and lead-free certification requirements relevant to your region.

Memory IC Selection Notes

Select this component when system architecture demands high-speed sequential and random reads with low latency. Compare against asynchronous NOR options if power constraints are critical, as synchronous interfaces offer better performance per watt. Ensure the host processor supports the required 1.7 V to 1.95 V I/O voltage levels. Validate that the 24-pin FBGA footprint fits within the PCB layout constraints.

Memory IC Part Context

This part belongs to the S26KS family of HyperFlash memories, which succeeded earlier synchronous NOR products. The family integrates advanced timing controls and error correction capabilities. It represents a transition toward higher density and faster access times compared to legacy parallel NOR flash, targeting modern compact electronic designs.

Memory IC Replacement Considerations

Check for direct pin-to-pin replacements within the same HyperFlash family, such as other S26KS variants with different densities. Verify electrical compatibility before substituting with older Spansion synchronous NOR models. Consult official obsolescence notices for any discontinued equivalents.
