Infineon Technologies S25FL512SAGMFAG13

Overview

S25FL512SAGMFAG13 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 S25FL512SAGMFAG13 datasheet, S25FL512SAGMFAG13 pinout, S25FL512SAGMFAG13 application, or S25FL512SAGMFAG13 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 package compatibility with legacy S25FL-A/K/P footprints.

Technical Context

This device implements Infineon's 65 nm MIRRORBIT™ technology with Eclipse™ architecture, enabling high-density nonvolatile storage with deterministic timing across SDR and DDR SPI 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 prior FL-S families.

The logic block integrates dedicated SRAM page buffers (512-byte), hardware ECC generation, and configurable protection registers (Status Register BP bits + ASP). Sector erase is exclusively uniform 256-KB, eliminating variable-block complexity - critical for deterministic firmware update timing in safety-critical embedded systems.

FAQ

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

The S25FL512SAGMFAG13 supports Quad DDR read commands at up to 80 MHz clock frequency, delivering 80 MBps throughput when VIO and VCC are both set to 3.0–3.6 V. This mode uses dual-edge sampling on all four I/O lines and requires proper setup/hold timing per datasheet Section 5.5.

Does this part support hardware reset via the RESET# pin?

Yes, the RESET# pin provides asynchronous hardware reset functionality. When asserted low, it forces the device into a known initial state, clears internal command latches, and disables all ongoing operations. The pin is internally pulled up and requires no external resistor per datasheet Section 2.3.

Can the WP# and HOLD# pins be used simultaneously as I/O2 and I/O3 in Quad mode?

No - WP# and HOLD# serve dual roles but cannot operate concurrently as I/O2/I/O3. When Quad mode is enabled via Status Register bit QUAD, these pins become bidirectional data lanes; however, hardware write protection or hold functionality is disabled during active Quad transfers.

Is the 1024-byte OTP array one-time programmable only, or can it be erased?

The 1024-byte OTP (One-Time Programmable) array is permanently programmable - once a bit is set to '0', it cannot be changed back to '1'. No erase command exists for this region. It is intended for immutable data such as cryptographic keys, device IDs, or calibration constants.
