Product details
Overview
S25FS064SDSBHM020 from Infineon is a 64 Mb (8 MB) serial NOR flash memory with SPI Multi-I/O interface, operating at 1.7–2.0 V supply and supporting DDR Quad I/O read up to 80 MBps. It features 65-nm MIRRORBIT™ technology, hardware ECC, hybrid/uniform sector erase options, and AEC-Q100 Grade 2 automotive qualification (–40°C to +105°C). Used in automotive ADAS boot code storage and industrial firmware update modules.
For engineers reviewing the S25FS064SDSBHM020 datasheet, S25FS064SDSBHM020 pinout, S25FS064SDSBHM020 application, or S25FS064SDSBHM020 equivalent, key selection factors include DDR Quad I/O throughput, 100K program-erase endurance, OTP array security, SFDP/CFI configuration support, and SOIC-8 package compatibility with legacy S25FL-S designs.
Technical Context
This device implements a QPI-capable SPI-MIO interface with configurable 24-/32-bit addressing, burst wrap and XIP continuous read modes, and dual/quad/DDR command subsets aligned with S25FL1-K/S25FL-P families. Its ECLIPSE architecture enables simultaneous read-while-write via program/erase suspend-resume functionality.
The internal hardware ECC corrects single-bit errors on-the-fly during read operations, while the 1024-byte OTP array supports secure boot key storage. Sector protection uses status register bits plus Advanced Sector Protection (ASP) with password-controlled read access and boot-code-triggered individual sector locking.

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S25FS064SDBHVF020 | LGA-8 (5×6 mm) package; identical electrical specs and feature set | Requires PCB redesign for LGA footprint; better thermal dissipation in space-constrained modules | Select when board layout prioritizes thermal performance and smaller footprint over SOIC rework compatibility |
| S25FL064LAFMFI000 | Legacy 65 nm S25FL-L family; no DDR mode; max Quad I/O = 40 MBps; lacks ASP and OTP | Lower cost for non-security-critical consumer applications; not AEC-Q100 qualified | Choose only for cost-sensitive, non-automotive designs where DDR throughput and advanced protection are unnecessary |
Compared with S25FS064SDSBHM020, the LGA variant offers identical functionality in a thermally superior package, while the S25FL064L lacks DDR, ASP, OTP, and automotive qualification-making it unsuitable for safety-critical or secure firmware roles.

FAQ
Is S25FS064SDSBHM020 pin-compatible with S25FL128S?
No. While both are Infineon SPI flash devices, S25FL128S is 128 Mb and uses a different pinout for WP#/RESET# functions. S25FS064SDSBHM020 shares pin mapping only with S25FS064S variants in SOIC-8, not higher-density S25FL families.
Does this device support execute-in-place (XIP) operation?
Yes. The device supports continuous read mode with wrap-around addressing, enabling true XIP execution of code directly from flash without copying to RAM-verified in Infineon's AN219277 application note for ARM Cortex-M hosts.
What is the purpose of the IO3_RESET# pin in QPI mode?
In QPI mode, IO3 operates exclusively as RESET#; it cannot function as a data I/O. This dedicated reset path ensures reliable hardware initialization independent of SPI bus state, critical for fail-safe boot sequences in automotive systems.
Can the 1024-byte OTP array be reprogrammed after initial programming?
No. The OTP array is one-time programmable by design. Once written, bits can only be changed from '1' to '0'; no erase or rewrite capability exists. This guarantees immutability of stored keys or calibration data across the device's lifetime.
