Product details
Overview
S25FS064SDSMFM010 from Infineon Technologies is a 64 Mb (8 MB) serial NOR flash memory IC with SPI Multi-I/O interface, 1.8 V single-supply operation, and industrial temperature range (–40°C to +85°C). It supports DDR Quad I/O read at 80 MHz (80 MBps), 256/512-byte page programming, hardware ECC, and hybrid/uniform sector erase options. Used in embedded boot code storage for microcontrollers in industrial control systems.
For engineers reviewing the S25FS064SDSMFM010 datasheet, S25FS064SDSMFM010 pinout, S25FS064SDSMFM010 application, or S25FS064SDSMFM010 equivalent, key selection criteria include SPI-MIO timing compliance, 1.7–2.0 V VCC tolerance, AEC-Q100 Grade 3 qualification, SFDP/CFI support, and OTP array size for secure firmware storage.
Technical Context
This device implements Infineon's 65-nm MIRRORBIT™ technology with ECLIPSE architecture, enabling high-density, low-voltage NOR flash operation. It features dual-mode SPI interface supporting both legacy single-data-rate (SDR) and double-data-rate (DDR) protocols, with QPI mode for quad-parallel instruction execution.
The memory array is organized with configurable sector architecture: eight 4 KB + one 32 KB physical sectors at top/bottom plus uniform 64 KB or 256 KB blocks. Internal hardware ECC provides single-bit error correction during read operations without host intervention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 64 Mb (8 MB) - sufficient for full MCU boot image + firmware update partition in resource-constrained edge nodes |
| Interface | SPI Multi-I/O with DDR option - enables 80 MBps read throughput in DDR Quad I/O mode for fast XIP execution |
| Voltage Range | 1.7 V to 2.0 V - compatible with modern low-power SoC I/O rails and eliminates level-shifting in 1.8 V systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Cypress S25FL064L | Larger 133 MHz max clock; no DDR mode; 3.0 V only; lacks SFDP v1.6 support | Requires voltage translation in 1.8 V systems; no DDR acceleration for XIP | Select only if legacy 3.0 V design and SDR-only interface suffice |
| Winbond W25Q64JW | 1.8 V operation; supports octal DTR but no DDR Quad I/O; 64 KB erase only (no hybrid sectors) | Higher read bandwidth possible with octal mode, but incompatible command set and no 4 KB sector option | Prefer for new designs needing octal interface; avoid if hybrid sector flexibility is required |
Compared with S25FS064SDSMFM010, the S25FL064L requires system-level voltage translation and lacks DDR acceleration, while the W25Q64JW offers octal bandwidth but sacrifices sector granularity and SFDP-based configurability.

FAQ
Does S25FS064SDSMFM010 support Quad Peripheral Interface (QPI) mode?
Yes, it supports QPI mode with quad-parallel instruction execution, enabling faster command throughput and reduced bus occupancy compared to standard SPI. QPI mode is enabled via status register configuration and requires host controller support for 4-bit command/address/data transfers.
What is the function of the IO3/RESET# pin?
The IO3/RESET# pin serves as an asynchronous hardware reset input. When asserted low, it forces the device into a known initial state, clears internal status registers, and terminates any ongoing program or erase operation. It can also be used as a general-purpose I/O in non-reset configurations after initialization.
How does the hybrid sector option affect firmware update design?
The hybrid sector option provides eight 4 KB sectors plus one 32 KB sector at either end of the address space, allowing small, frequent updates (e.g., patch files) in 4 KB units while reserving larger contiguous blocks for major firmware images. This avoids erasing unnecessary sectors during partial updates, reducing wear and improving update speed.
Is the 1024-byte OTP array reprogrammable?
No, the 1024-byte OTP (One-Time Programmable) array is permanently programmed during manufacturing or first-time field programming and cannot be erased or rewritten. It is intended for storing immutable data such as cryptographic keys, device serial numbers, or calibration constants that must remain tamper-resistant throughout the product lifetime.
