Infineon Technologies S25FL512SAGBHMA10

Overview

S25FL512SAGBHMA10 from Infineon is a 512 Mb (64 MB) serial NOR flash memory IC with SPI Multi-I/O interface, 3.0 V core supply, uniform 256-KB sector erase architecture, Quad-Input Page Programming, and integrated hardware ECC. It supports Fast/Quad/DDR read modes up to 80 MHz clock rate (80 MBps Quad DDR), operates across –40°C to +105°C (Industrial Plus), and is used in boot code storage for ARM Cortex-A/RISC-V-based edge gateways.

For engineers reviewing the S25FL512SAGBHMA10 datasheet, S25FL512SAGBHMA10 pinout, S25FL512SAGBHMA10 application, or S25FL512SAGBHMA10 equivalent, key selection criteria include Quad DDR read throughput, 100,000 program-erase cycles, OTP security array size, AEC-Q100 Grade 2 qualification, and SO16 vs. FBGA package compatibility with existing PCB layouts.

Technical Context

This device implements Infineon's 65 nm MIRRORBIT™ technology with Eclipse™ architecture, enabling true single-bit ECC correction per 512-byte page without software overhead. Its command set is backward-compatible with S25FL-A/K/P families and supports extended 32-bit addressing for >16 MB memory maps.

The dual-voltage I/O interface (VIO = 1.65–3.6 V, VCC = 2.7–3.6 V) allows interoperability with 1.8 V and 3.3 V host controllers, while AutoBoot functionality executes preconfigured Normal or Quad Read at power-up or reset-critical for deterministic boot timing in industrial PLCs.

FAQ

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

The S25FL512SAGBHMA10 supports up to 80 MHz clock frequency in Quad DDR mode, delivering 80 MBps effective read throughput. This is validated under VIO = VCC = 3.0–3.6 V conditions and requires strict PCB layout adherence to DDR timing margins per Infineon's layout guidelines in section 6.1 of the datasheet.

Does this part support hardware write protection independent of software commands?

Yes-WP# pin provides hardware-level write protection for status register bits and sector protection registers. When WP# is held low, all program and erase commands targeting protected sectors are blocked regardless of software state, meeting IEC 62443-3-3 requirements for secure firmware update paths.

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

The 1024-byte OTP array is strictly one-time programmable: bits can be changed from '1' to '0' only, with no provision for erasure or reprogramming. Once written, contents remain immutable-even after power cycling-ensuring cryptographic key persistence and tamper-evident configuration storage.

How does AutoBoot behavior interact with the status register's QUAD bit setting?

AutoBoot uses the QUAD bit value stored in the status register at power-up to determine whether to execute Normal or Quad Read. If QUAD=1, AutoBoot performs Quad Read from the configured address; if QUAD=0, it defaults to Normal Read-enabling flexible boot mode selection without external configuration pins.
