Infineon Technologies S25FL512SAGMFV013

Overview

S25FL512SAGMFV013 from Infineon is a 512 Mb (64 MB) serial NOR flash memory with SPI Multi-I/O interface, 3.0 V core supply, uniform 256-KB sectors, Quad-Input Page Programming, and hardware ECC. It supports Fast/Quad/DDR read modes up to 80 MHz and operates across industrial (–40°C to +85°C) and automotive AEC-Q100 Grade 2 (–40°C to +105°C) temperature ranges. Used in boot code storage for microcontrollers in industrial HMIs and automotive ADAS ECUs.

For engineers reviewing the S25FL512SAGMFV013 datasheet, S25FL512SAGMFV013 pinout, S25FL512SAGMFV013 application, or S25FL512SAGMFV013 equivalent, this page delivers verified electrical specs, SOIC-16 and FBGA package mapping, CFI/SFDP compliance, AutoBoot configuration, and real-world sector protection behavior - all critical for secure firmware update architecture and long-life embedded storage design.

Technical Context

This device implements Infineon's 65 nm MIRRORBIT™ technology with Eclipse™ architecture, enabling single-bit error correction via on-die hardware ECC and supporting both SDR and DDR SPI protocols. Its dual-voltage I/O (1.65–3.6 V) and core (2.7–3.6 V) rails allow interoperability with legacy and low-power host controllers.

The command set maintains footprint and register compatibility with S25FL-A/K/P families while extending addressing to 32 bits and adding Advanced Sector Protection (ASP) with password- or boot-code-controlled individual sector locking - essential for secure boot partitioning and OTA update integrity.

FAQ

What is the maximum clock frequency supported in DDR mode?

The S25FL512SAGMFV013 supports Fast Read DDR, Dual Read DDR, and Quad Read DDR at up to 80 MHz with VIO = VCC = 3.0–3.6 V, delivering 20 MBps, 40 MBps, and 80 MBps respectively. DDR operation requires proper setup/hold timing alignment per datasheet Section 5.5 and is disabled by default after power-up.

Does this part support JEDEC JESD216 SFDP?

Yes - it implements JEDEC JESD216B-compliant Serial Flash Discoverable Parameters (SFDP) in a dedicated address space, enabling automatic detection of density, timing parameters, and command sets by U-Boot, Linux mtd drivers, and vendor-agnostic flash programmers without hardcoded configuration.

How is the 1024-byte OTP array accessed and protected?

The OTP array is accessed via dedicated One-Time-Program commands (0x4B/0x4C) and locked permanently after programming. It resides at fixed address 0x00000000 in OTP space and is write-protected by status register bit SRWD and hardware WP# assertion - preventing accidental overwrite during field updates.

Can AutoBoot be configured to execute Quad Read from a non-default address?

Yes - AutoBoot address is programmable in the Configuration Register (CR) bits [23:8], allowing selection of any 64 KB-aligned location within the 64 MB address space. The boot command (Normal or Quad Read) and address persist through power cycles and are retained even after sector erases elsewhere in the array.
