Infineon Technologies S25FL512SAGBHI313

Overview

S25FL512SAGBHI313 from Infineon is a 512 Mb (64 MB) serial NOR flash memory IC 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 hardware ECC for single-bit 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 S25FL512SAGBHI313 datasheet, S25FL512SAGBHI313 pinout, S25FL512SAGBHI313 application, or S25FL512SAGBHI313 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. Its dual-voltage I/O (1.65–3.6 V) and core (2.7–3.6 V) support mixed-signal SoC interfacing while maintaining full command set compatibility with S25FL-A/K/P families.

The integrated control logic handles automatic ECC generation during programming, uniform 256-KB sector erase with 100,000 program-erase cycles, and configurable block protection via status register bits or advanced sector protection (ASP) using boot code or password. CFI and SFDP tables provide standardized configuration discovery.

FAQ

What is the maximum Quad DDR read speed of the S25FL512SAGBHI313?

The device achieves 80 MBps Quad DDR read throughput at 80 MHz clock frequency with VIO = VCC = 3.0–3.6 V. This performance is measured under JEDEC-compliant AC test conditions and requires proper PCB layout with matched trace lengths and controlled impedance (50 Ω ±10%) for all I/O lines to maintain signal integrity.

Does the S25FL512SAGBHI313 support hardware reset recovery without host intervention?

Yes. The RESET# pin provides asynchronous hardware reset that clears internal command state, resets status registers, and forces the device into standby mode. After deassertion, the device automatically enters AutoBoot mode if enabled, executing a preconfigured read command without host SPI traffic - critical for fail-safe boot recovery in automotive systems.

How is the 1024-byte OTP array used in secure firmware deployment?

The OTP array is one-time programmable and stores immutable values such as cryptographic root keys, device-specific identifiers, or secure boot policy flags. Once written, contents cannot be erased or modified. It is accessed via dedicated JEDEC-standard commands and protected against accidental overwrite by hardware fuse-lock mechanisms verified during manufacturing test.

Can the S25FL512SAGBHI313 operate with different core and I/O voltages simultaneously?

Yes. The device supports independent VCC (2.7–3.6 V) and VIO (1.65–3.6 V) supplies, enabling direct interface with 1.8 V microcontrollers while maintaining full 3.3 V core performance. This eliminates level-shifter components and reduces BOM count in mixed-voltage designs, provided both supplies meet datasheet ripple and sequencing requirements.
