Infineon Technologies S25FL512SAGMFB013

Overview

S25FL512SAGMFB013 from Infineon is a 512 Mb (64 MB) serial NOR flash memory with SPI Multi-I/O interface, designed for boot code storage and firmware execution in embedded systems. It supports Quad, Dual, and DDR read modes up to 80 MHz clock (80 MBps Quad DDR), features 256-KB uniform sectors, 100,000 program-erase cycles, and 20-year data retention. Used in industrial controllers requiring fast, reliable nonvolatile code storage.

For engineers reviewing the S25FL512SAGMFB013 datasheet, S25FL512SAGMFB013 pinout, S25FL512SAGMFB013 application, or S25FL512SAGMFB013 equivalent, key selection criteria include SPI Multi-I/O timing compliance, 256-KB sector erase granularity, OTP security configuration, AEC-Q100 Grade 2 qualification, and FBGA-24 (FAB024) package compatibility.

Technical Context

This device implements Infineon's 65 nm MIRRORBIT™ technology with Eclipse™ architecture, enabling high-density, low-power serial flash operation. It supports SPI clock modes 0 and 3, extended 32-bit addressing, and CFI/SFDP parameter discovery for automatic host configuration.

The integrated hardware ECC provides single-bit error correction during read operations, while AutoBoot enables configurable power-up execution of Normal or Quad Read commands at a preselected address-critical for deterministic boot latency in real-time systems.

FAQ

What is the maximum supported clock frequency for Quad DDR read operations?

The S25FL512SAGMFB013 supports Quad DDR read at up to 80 MHz clock frequency, delivering 80 MBps effective throughput when VIO = VCC = 3.0–3.6 V. This requires strict adherence to AC timing parameters including tDSH (data setup hold) and tDH (data hold time), as specified in Section 5.5 of the datasheet. The device does not support DDR above 80 MHz, even with tighter voltage margins.

Does this part support hardware reset via the RESET# pin, and what is its behavior?

Yes, the RESET# pin provides asynchronous hardware reset. When asserted low, it terminates all ongoing operations, clears internal command state, resets status registers to default values, and places the device into standby mode. Release of RESET# initiates internal initialization, after which the device is ready to accept new commands within tRES1 (max 100 µs). No external delay is required before issuing the first post-reset command.

How is Advanced Sector Protection (ASP) configured and enforced?

ASP is configured by writing password-protected commands to dedicated ASP registers, then setting ASP enable bits in the configuration register. Once enabled, individual 256-KB sectors can be locked/unlocked only via valid password authentication or boot code execution. Lock status persists across power cycles and cannot be overridden by standard block protection bits-providing hierarchical, tamper-resistant firmware partitioning.

Can the VIO and VCC supplies operate at different voltages simultaneously?

Yes, VIO (1.65–3.6 V) and VCC (2.7–3.6 V) are independently powered. This allows interfacing with 1.8 V hosts while maintaining full core performance, provided VIO ≥ 1.65 V and VCC ≥ 2.7 V. Voltage sequencing is not required, but VCC must be stable before asserting CS#; VIO may ramp concurrently or slightly after VCC per Section 4.4 of the datasheet.
