Infineon Technologies S25FL512SAGBHMA13

Overview

S25FL512SAGBHMA13 from Infineon is a 512 Mb (64 MB) serial NOR flash memory with SPI Multi-I/O interface, 3.0 V core supply, and uniform 256-KB sector architecture. It supports Quad Read at up to 52 MBps, internal ECC for single-bit error correction, and AutoBoot execution from preselected address on power-up or reset - deployed in industrial control firmware storage and automotive infotainment boot code retention.

For engineers reviewing the S25FL512SAGBHMA13 datasheet, S25FL512SAGBHMA13 pinout, S25FL512SAGBHMA13 application, or S25FL512SAGBHMA13 equivalent, key selection criteria include Quad DDR read performance (80 MBps), AEC-Q100 Grade 2 qualification (–40°C to +105°C), OTP security array size (1024 bytes), and SO16/FBGA package compatibility with legacy S25FL-P designs.

Technical Context

This device implements Infineon's 65 nm MIRRORBIT™ technology with Eclipse™ architecture, enabling high-density nonvolatile storage with deterministic timing across SPI SDR and DDR modes. It supports all four SPI clock polarity/phase combinations (CPOL/CPHA = 0/0 and 1/1), extended 32-bit addressing, and CFI/JEDEC SFDP parameter discovery for host auto-configuration.

The integrated control logic handles automatic ECC generation during programming, hardware/software block protection via status register bits, and Advanced Sector Protection (ASP) with password- or boot-code-controlled individual sector lockdown - eliminating external error-handling firmware overhead in safety-critical boot paths.

Equivalent & Alternatives

The following parts are listed as comparable options for similar serial NOR flash memory applications.

Compared with S25FL512SAGBHMA13, the Infineon FBGA variant offers identical functionality in smaller form factor, while the Winbond part sacrifices AutoBoot, ECC, and dual-voltage I/O - making it unsuitable for automotive or industrial boot-critical roles despite matching density.

FAQ

What is the maximum clock frequency supported in DDR mode?

The S25FL512SAGBHMA13 supports Fast Read DDR, Dual Read DDR, and Quad Read DDR at up to 80 MHz clock frequency, delivering 20 MBps, 40 MBps, and 80 MBps read throughput respectively when VIO = VCC = 3.0–3.6 V. DDR timing requires strict setup/hold alignment per datasheet Section 5.5, and is disabled below 3.0 V I/O supply.

Does this part support 32-bit addressing in all command modes?

Yes - extended 32-bit addressing is enabled by default and supported across all read, program, and erase commands. The device implements JEDEC JESD216 SFDP v1.6, allowing host drivers to auto-detect address width and configure accordingly without manual register writes.

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

The OTP array resides at fixed address 0x00000000 and is accessed via dedicated One-Time-Program commands (0x4B, 0x42). Once programmed, bits cannot be reset. Protection is enforced by Status Register Lock Bit (SRP) and hardware WP# assertion - both must be cleared before OTP write commands are accepted.

Can AutoBoot be configured to execute from any address in the memory map?

AutoBoot reads from a user-programmable 24-bit address stored in the Configuration Register (CR2[23:0]). Valid range is 0x000000 to 0xFFFFFF, covering the first 16 MB of the 64 MB array. Address must align to page boundary (512-byte) for Quad Read AutoBoot; misaligned addresses trigger Normal Read instead.
