Infineon Technologies S25FS064SAGNFN030

Overview

S25FS064SAGNFN030 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 internal 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 high reliability and AEC-Q100 Grade 2 qualification.

For engineers reviewing the S25FS064SAGNFN030 datasheet, S25FS064SAGNFN030 pinout, S25FS064SAGNFN030 application, or S25FS064SAGNFN030 equivalent, this page delivers verified technical context, real-world timing performance, package-specific pin mapping, security features including OTP and ASP, and validated alternative parts for migration or sourcing continuity.

Technical Context

This device implements Infineon's 65-nm MIRRORBIT™ technology with ECLIPSE architecture, enabling fast random access and robust data retention (20 years minimum). Its SPI-MIO interface supports legacy SPI modes 0/3, QPI mode, and DDR operation with configurable 24-/32-bit addressing - critical for firmware update flexibility in resource-constrained embedded systems.

The integrated control logic handles automatic ECC generation during program/erase, suspend/resume for both program and erase operations, and SFDP/CFI compliance for self-configuration. Sector protection includes hardware/software status register lock, advanced sector protection (ASP) with password-controlled read access, and 1024-byte OTP array for secure key or calibration storage.

FAQ

What is the maximum clock frequency supported in DDR Quad I/O mode?

The S25FS064SAGNFN030 supports up to 80 MHz in DDR Quad I/O mode, delivering 80 MBps effective read bandwidth. This is confirmed in Table 1 of the official Infineon datasheet (002-03631 Rev. *I), where DDR Quad I/O Read is specified at 80 MHz with 80 MBps throughput. The device requires proper impedance-controlled routing and termination to maintain signal integrity at this rate.

Does this part support 32-bit addressing for devices larger than 16 MB?

Yes, the S25FS064SAGNFN030 supports both 24-bit and 32-bit addressing modes via extended address commands, as documented in Section 2 of the datasheet. Although its 64 Mb capacity fits within 24-bit addressing (16 MB limit), the 32-bit mode ensures software compatibility with higher-density successors and simplifies firmware abstraction layers across product families.

How does the Advanced Sector Protection (ASP) differ from standard status register protection?

ASP provides individual sector-level locking controlled by boot code or user-defined password, unlike status register protection which locks contiguous sector ranges. ASP enables fine-grained access control - for example, locking only the bootloader sector while allowing runtime parameter updates in adjacent sectors - and supports password-protected read access, adding a layer beyond hardware write-enable restrictions.

Is the 1024-byte OTP array one-time programmable per byte or per block?

The 1024-byte OTP array is programmed in 8-byte rows, with each row permanently locked after programming. Once a row is written and locked, it cannot be altered. This structure allows partial OTP usage - such as storing unique device IDs in early rows and calibration data in later rows - while preserving unused sections for future field updates or manufacturing flexibility.
