Infineon Technologies S25FL512SAGBHA213

Overview

S25FL512SAGBHA213 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 256-KB uniform sector erase architecture. It supports Quad Read at up to 52 MBps, features hardware ECC, 100,000 program-erase cycles, and operates across –40°C to +105°C (Industrial Plus grade). Used in boot code storage for embedded microcontrollers in industrial HMIs.

For engineers reviewing the S25FL512SAGBHA213 datasheet, S25FL512SAGBHA213 pinout, S25FL512SAGBHA213 application, or S25FL512SAGBHA213 equivalent, key selection criteria include Quad DDR read performance (80 MBps), OTP security (1024-byte array), AEC-Q100 Grade 2 qualification, 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 single-bit error correction via integrated hardware ECC logic. Its dual-voltage I/O (1.65–3.6 V) and core (2.7–3.6 V) support flexible system-level voltage scaling.

The SPI interface supports all four clock modes (CPOL/CPHA 0/0 and 1/1), DDR operation, 32-bit extended addressing, and command sets fully compatible with S25FL-A/K/P families-ensuring migration path continuity without PCB redesign.

FAQ

What is the maximum clock frequency supported in DDR mode?

The S25FL512SAGBHA213 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 respectively-achievable only when both VIO and VCC are ≥3.0 V. This DDR mode requires precise setup/hold timing per datasheet Section 5.5 and is incompatible with 1.8 V I/O interfaces.

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

Yes, the RESET# pin provides asynchronous hardware reset functionality: asserting it low for ≥20 ns forces the device into hardware reset state, clearing internal registers and aborting any ongoing operation. After release, the device enters standby mode and waits for CS# assertion before accepting new commands-no internal oscillator restart delay is required.

Can the WP# and HOLD# pins be used as general-purpose I/Os?

Yes-when Multi-I/O mode is enabled via status register configuration, WP# becomes IO2 and HOLD# becomes IO3, allowing full Quad SPI operation. However, in standard SPI mode, they retain dedicated hardware protection functions and must not be driven externally during active commands to avoid bus contention or unintended protection activation.

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: bits can be changed from '1' to '0' only, with no provision for erasure or reprogramming. Once written, contents remain intact across power cycles and temperature extremes-making it suitable for immutable keys, calibration constants, or device-specific identifiers that must survive field updates.
