Infineon Technologies S25FS064SDSMFM013

Overview

S25FS064SDSMFM013 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), 100,000 program-erase cycles, 20-year data retention, and integrated hardware ECC for single-bit error correction. Used in boot code storage for microcontroller-based edge nodes requiring fast XIP-capable nonvolatile memory.

For engineers reviewing the S25FS064SDSMFM013 datasheet, S25FS064SDSMFM013 pinout, S25FS064SDSMFM013 application, or S25FS064SDSMFM013 equivalent, key selection criteria include SPI-MIO timing compliance, hybrid/uniform sector erase flexibility, OTP array size (1024 bytes), AEC-Q100 grade compatibility, and 65-nm MIRRORBIT™ process reliability.

Technical Context

This device implements Infineon's ECLIPSE architecture with MIRRORBIT™ technology, enabling high-density NOR flash with deterministic latency for execute-in-place (XIP) operation. It supports both legacy SPI and quad peripheral interface (QPI) modes, with configurable 24-/32-bit addressing and SFDP/CFI for runtime configuration discovery.

The logic block integrates dual I/O path control, dedicated reset and write-protect terminals with dual-function capability (IO2/IO3), and on-die ECC generation aligned to page-program and read operations. Erase suspend/resume and program suspend/resume enable real-time system responsiveness during background flash maintenance.

FAQ

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

The S25FS064SDSMFM013 supports DDR Quad I/O operation up to 80 MHz, delivering 80 MBps effective read throughput. This is specified in Table 1 of the datasheet and validated across the full industrial temperature range. The device requires proper PCB layout with matched trace lengths and controlled impedance to maintain signal integrity at this rate.

Does this part support both 24-bit and 32-bit addressing?

Yes, the S25FS064SDSMFM013 supports extended addressing via configurable 24-bit or 32-bit address modes. This is enabled through status register bits and allows seamless migration between density tiers without changing host driver logic. The default is 24-bit for backward compatibility with legacy SPI flash controllers.

How is hardware write protection implemented on this device?

Hardware write protection is implemented via the WP# pin (IO2), which when held low disables all program and erase commands to protected sectors. Protection granularity is controlled by status register bits defining contiguous sector ranges. This operates independently of software protection and remains active during power transitions.

Is the OTP array reprogrammable after initial programming?

No, the 1024-byte OTP (One-Time Programmable) array is permanently programmed using high-voltage pulses and cannot be erased or rewritten. Once written, its contents persist across power cycles and device resets. It is intended for immutable data such as cryptographic keys, calibration coefficients, or unique device identifiers.
