S26KL128SDABHN020

Memory IC Overview

The Infineon S26KL128SDABHN020 is a 128 Mbit (16 MB) HYPERFLASH NOR flash memory device featuring the HYPERBUS interface. It supports 3.0 V and 1.8 V I/O voltages with an 8-bit data bus. The device achieves up to 166 MHz clock rates at 1.8 V, providing sustained read throughput of 333 MBps. Key specifications include a 96 ns initial random read access time, uniform 256-KB sector erase capability, and embedded ECC for one-bit correction and two-bit detection.

Memory IC Feature Summary

• Supports high-speed DDR data transfers via the HYPERBUS protocol with configurable burst characteristics.
• Integrates embedded Error Correction Code (ECC) logic for automatic single-bit error correction during read operations.
• Includes hardware-accelerated Cyclic Redundancy Check (CRC) calculation capabilities over user-defined address ranges.
• Features advanced sector protection mechanisms supporting both volatile and non-volatile locking methods.

Memory IC Applications

• Boot code storage in industrial systems requiring fast execution from memory.
• Data logging applications utilizing the embedded CRC functionality for integrity verification.
• Automotive electronic control units (ECUs) leveraging AEC-Q100 certified variants for reliability.
• Embedded systems needing secure parameter storage with dedicated parameter sectors.

Memory IC Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm voltage levels, temperature grades, and package variations. Ensure compatibility with host system timing requirements for the HYPERBUS interface. Confirm that the selected density matches the application's storage needs, as this model represents the 128 Mbit capacity within the family.

Memory IC Selection Notes

Select this component when high-speed sequential read performance is critical for booting or executing code directly from memory. Consider the integrated ECC feature if data integrity is paramount without external processing overhead. Evaluate the thermal operating range requirements, as the device supports extended industrial temperatures suitable for harsh environments.

Memory IC Part Context

This part belongs to the HYPERFLASH family, which combines high-speed parallel-like performance with low pin-count serial interfaces. The S26KL series specifically targets industrial and automotive markets, offering robust data retention and endurance specifications compared to standard commercial grade memories.

Memory IC Replacement Considerations

Check for other densities within the same HYPERFLASH family, such as 256 Mbit or 512 Mbit variants, if storage requirements differ. Verify pinout compatibility with existing PCB layouts, as package dimensions may vary slightly between different density options in the same series.
