Product details
Overview
S25FS064SDSMFV010 from Infineon is a 64 Mb (8 MB) serial NOR flash memory with SPI Multi-I/O interface, operating at 1.8 V supply. It supports DDR Quad I/O read up to 80 MBps, features hardware ECC for single-bit error correction, and offers hybrid sector erase (eight 4 KB + one 32 KB sectors) plus uniform 64 KB/256 KB block erase options. Used in industrial microcontroller boot code storage requiring AEC-Q100 Grade 2 qualification (–40°C to +105°C).
For engineers reviewing the S25FS064SDSMFV010 datasheet, S25FS064SDSMFV010 pinout, S25FS064SDSMFV010 application, or S25FS064SDSMFV010 equivalent, key selection criteria include 1.8 V operation, DDR Quad I/O throughput, SFDP/CFI configuration support, OTP array size, and AEC-Q100 Grade 2 temperature compliance.
Technical Context
This device implements Infineon's 65-nm MIRRORBIT™ technology with ECLIPSE architecture, enabling high-density, low-voltage NOR flash operation. It supports both legacy SPI and QPI modes, with configurable 24-/32-bit addressing and burst wrap/continuous XIP read modes.
The internal control logic integrates automatic ECC generation, program/erase suspend-resume capability, and dual protection mechanisms: status register-based block protection and Advanced Sector Protection (ASP) with password- or boot-code-controlled access. Hybrid sector architecture allows flexible firmware partitioning between small boot sectors and large application blocks.

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S25FS064SAGMFV010 | Same die, LGA 5×6 mm package instead of SOIC; 0.4 mm pitch, lower profile, better thermal dissipation | Preferred for space-constrained PCBs with automated optical inspection and reflow requirements | Select when board area and thermal management outweigh hand-soldering convenience |
| S25FL064LAFMFI000 | Legacy 65 nm FL-L family; no DDR mode, max 80 MHz SDR clock, no ASP or OTP array | Limited to cost-sensitive consumer devices without security or high-speed XIP needs | Choose only if DDR, ECC, or AEC-Q100 Grade 2 are not required |
Compared with S25FS064SAGMFV010, this SOIC variant offers easier manual assembly and legacy footprint compatibility; versus S25FL064LAFMFI000, it delivers measurable improvements in boot speed, data integrity, and security-justifying upgrade where functional safety or field update robustness is mandated.

FAQ
What is the maximum clock frequency supported in DDR Quad I/O mode?
The S25FS064SDSMFV010 supports up to 80 MHz in DDR Quad I/O mode, delivering 80 MBps effective read bandwidth. This frequency is validated across the full industrial temperature range (–40°C to +105°C) and requires proper PCB layout with matched trace lengths and controlled impedance for all four I/O lines.
Does this part support both 24-bit and 32-bit addressing?
Yes, the device supports configurable extended addressing: 24-bit mode for compatibility with legacy 16 MB address space, and 32-bit mode to access the full 64 Mb capacity. Address mode is selected via configuration register bit CR3[1], and switching requires issuing the Write Enable and Write Configuration Register commands.
How does the Advanced Sector Protection (ASP) differ from standard status register protection?
ASP enables per-sector locking using either boot code execution or a user-defined password, whereas standard protection relies solely on status register bits that guard contiguous sector ranges. ASP provides granular, non-contiguous sector control and adds authentication layers beyond simple hardware write-enable pin assertion.
Is the 1024-byte OTP array one-time programmable per byte or per block?
The 1024-byte OTP array is organized as 32 × 32-byte sectors, each individually one-time programmable. Once a sector is programmed, its contents cannot be altered-even by erasing adjacent sectors. Programming is performed via dedicated OTP Program commands and requires prior Write Enable activation.
