Product details
Overview
S25FS064SAGNFI033 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 implements MIRRORBIT™ technology with ECLIPSE architecture, supports DDR Quad I/O read up to 80 MBps, features hardware ECC for single-bit correction, and offers hybrid/ uniform sector erase options including 4 KB, 64 KB, and 256 KB blocks. It is qualified for industrial (–40°C to +85°C) and automotive AEC-Q100 Grade 3 applications.
For engineers reviewing the S25FS064SAGNFI033 datasheet, S25FS064SAGNFI033 pinout, S25FS064SAGNFI033 application, or S25FS064SAGNFI033 equivalent, key selection considerations include its 1.7–2.0 V supply range, SFDP/CFI configuration support, OTP array (1024 bytes), programmable block protection, and compatibility with S25FL1-K/S25FL-P/S25FL-S families.
Technical Context
This device implements a serial flash architecture with dual- and quad-mode I/O capability, supporting both legacy SPI and QPI protocols. Its command set includes Normal/Fast/Dual/Quad/DDR Quad I/O reads, burst wrap and XIP modes, and configurable addressing (24-/32-bit). The internal ECC engine operates transparently during program/erase, correcting single-bit errors in real time without host intervention.
The memory array uses 65-nm MIRRORBIT™ cells with ECLIPSE architecture to enable high endurance (100,000 P/E cycles) and 20-year data retention. Sector protection is implemented via status register bits, hardware/software WP# control, and Advanced Sector Protection (ASP) with password-protected read access - all configurable per sector or boot region.

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S25FS064SAGNFI020 | Same die, identical specs, but rated for Industrial (–40°C to +85°C) only - no AEC-Q100 qualification | Lacks automotive qualification; unsuitable for under-hood or safety-critical ECUs | Select when automotive qualification is not required and cost optimization is prioritized |
| S25FL164KAGNFI000 | 64 Mb, 3.0 V supply, SDR-only interface (no DDR/Quad I/O), lower max read speed (40 MBps) | Not pin-compatible; requires board redesign and firmware adaptation for timing and command set | Choose only if legacy 3.0 V system integration or simplified interface is mandatory |
Compared with S25FS064SAGNFI020, this part adds AEC-Q100 Grade 3 qualification and extended temperature margin; versus S25FL164KAGNFI000, it delivers 2× read bandwidth, 1.8 V operation, and DDR/Quad I/O flexibility - enabling faster boot and smaller power supplies.

FAQ
Is S25FS064SAGNFI033 pin-compatible with S25FL1-K series devices?
Yes - it maintains footprint compatibility with S25FL1-K, S25FL-P, and S25FL-S families per Infineon's migration notes. Pin assignments, package dimensions (e.g., SOIC 208 mil), and basic SPI command subsets match, enabling drop-in replacement in many designs. However, QPI mode and DDR Quad I/O require firmware enablement and timing validation.
Does this device support Execute-in-Place (XIP) mode?
Yes - the S25FS064SAGNFI033 supports continuous read mode (XIP) with burst wrap capability across all read command types (Fast, Dual, Quad, DDR Quad I/O). This allows direct code execution from flash without copying to RAM, reducing system memory footprint and boot latency in microcontroller-based systems.
What is the function of the RESET#/IO3 pin?
RESET#/IO3 serves dual roles: as an active-low hardware reset input that initiates cold/warm reset sequences, and as the fourth I/O line (IO3) in Quad and DDR Quad I/O modes. Its dual functionality is controlled by configuration register settings and is automatically managed during command execution without external multiplexing.
How is the 1024-byte OTP array accessed and protected?
The OTP array is accessed via dedicated SPI commands (e.g., RDSCUR, WRSR, PROG) and resides in a physically isolated memory region. Once programmed, bits cannot be erased. Protection is enforced by status register lock bits and ASP - preventing accidental writes unless explicitly unlocked via password or boot code sequence defined in the security configuration.
