Product details
Overview
S25FS064SAGBHI020 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, 256/512-byte page programming, hardware ECC, hybrid/uniform sector erase, and AEC-Q100 Grade 2 automotive qualification (–40°C to +105°C). Used in automotive ADAS ECUs for firmware storage with XIP support.
For engineers reviewing the S25FS064SAGBHI020 datasheet, S25FS064SAGBHI020 pinout, S25FS064SAGBHI020 application, or S25FS064SAGBHI020 equivalent, key selection criteria include 1.8 V operation, DDR Quad I/O throughput, AEC-Q100 Grade 2 temperature rating, OTP security, and SFDP/CFI configuration compliance.
Technical Context
This device implements Infineon's 65-nm MIRRORBIT™ technology with ECLIPSE architecture, enabling high endurance (100,000 P/E cycles) and 20-year data retention. Its dual-mode SPI interface supports legacy single-data-rate (SDR) and double-data-rate (DDR) protocols, with QPI mode for command efficiency and burst wrap/continuous XIP for code execution.
The logic block includes dedicated control logic for automatic ECC generation/correction, programmable sector protection via status register and ASP, and flexible addressing (24-/32-bit) with SFDP v1.6 and CFI for runtime configuration discovery. Reset behavior supports both cold power-on and warm hardware reset via IO3_RESET#.

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Cypress S25FL132K0XMFI010 | 32 Mb density, no DDR mode, 1.8 V, AEC-Q100 Grade 3 only | Limited to smaller firmware images; lacks DDR bandwidth for XIP-heavy designs | Select only if firmware size < 4 MB and DDR not required |
| Winbond W25Q64JWIM TR | 64 Mb, 1.8 V, QPI-only interface, no SFDP v1.6, 65 nm process | Requires QPI-specific host driver; no runtime parameter discovery via SFDP | Choose when host supports QPI exclusively and SFDP-based auto-configuration is unnecessary |
Compared with S25FS064SAGBHI020, the Cypress alternative offers lower density and no DDR support-limiting XIP performance-while the Winbond part omits SFDP v1.6 and DDR, reducing design flexibility for future-proofed automotive firmware stacks.

FAQ
What is the maximum DDR Quad I/O read speed for S25FS064SAGBHI020?
The device achieves 80 MBps DDR Quad I/O read throughput at 80 MHz clock frequency, as specified in Table 1 of the datasheet. This performance is enabled by simultaneous sampling on both clock edges across four I/O lines, and requires host controller support for DDR mode and proper PCB layout with matched trace lengths.
Does S25FS064SAGBHI020 support 32-bit addressing?
Yes, it supports extended addressing with both 24-bit and 32-bit address options, allowing full access to the entire 64 Mb address space without bank switching. The addressing mode is selected via configuration register bits and is compatible with SFDP-defined addressing instructions for seamless host integration.
How is hardware reset implemented on this device?
Hardware reset is triggered by asserting the IO3_RESET# pin low for ≥20 ns, initiating a warm reset that clears internal state without power cycling. The pin is multiplexed with IO3 functionality and must be pulled high during normal operation; reset timing and recovery are defined in Section 5.3 of the datasheet.
What security mechanisms protect against unauthorized firmware modification?
It provides three layers: (1) Status register-based block protection for contiguous sector locking, (2) Advanced Sector Protection (ASP) enabling password-protected individual sector access control, and (3) a 1024-byte One-Time-Programmable (OTP) array for immutable key storage-each enforced at silicon level without host software dependency.
