Infineon Technologies S25FL512SAGBHIA13

Overview

S25FL512SAGBHIA13 from Infineon is a 512 Mb (64 MB) serial NOR flash memory with SPI Multi-I/O interface, 3.0 V core supply, uniform 256-KB sectors, Quad Read up to 52 MBps, and integrated hardware ECC. It supports AutoBoot, CFI, and DDR read modes, and is qualified for Industrial Plus (–40°C to +105°C) operation in FBGA package.

For engineers reviewing the S25FL512SAGBHIA13 datasheet, S25FL512SAGBHIA13 pinout, S25FL512SAGBHIA13 application, or S25FL512SAGBHIA13 equivalent, this device is selected for high-reliability embedded boot storage requiring fast Quad/DDR read access, sector-level protection, and 100K program-erase cycles in space-constrained industrial control and automotive infotainment systems.

Technical Context

This FL-S series flash implements Infineon's 65 nm MIRRORBIT™ technology with Eclipse™ architecture, enabling true single-bit ECC correction and uniform 256-KB sector erase granularity. It supports SPI clock modes 0 and 3, extended 32-bit addressing, and command-set compatibility with S25FL-A/K/P families.

The device features dual power domains (VCC = 2.7–3.6 V, VIO = 1.65–3.6 V), enabling interoperability with 1.8 V or 3.3 V host interfaces. Its AutoBoot function executes preconfigured Normal or Quad Read at power-up/reset, reducing firmware initialization overhead in real-time systems.

FAQ

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

The S25FL512SAGBHIA13 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 when VIO = VCC = 3.0–3.6 V. These rates are specified under AC test conditions with controlled slew rate and termination, and require host controller DDR timing compliance.

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

Yes - the WP#/IO2 pin provides hardware write protection. When asserted low, it disables all program and erase operations regardless of status register settings. This feature operates independently of software commands and remains active even after power cycling, offering fail-safe protection for critical sectors.

How is the 1024-byte OTP array accessed and secured?

The OTP array is accessed via dedicated One-Time-Program commands (0x4B and 0x42) and resides at fixed address 0x00000000 in the OTP address space. Once programmed, bits cannot be reset. Access requires prior write enable and is blocked if the OTP lock bit is set, preventing further writes without hardware reset or power cycle.

Can the device operate with VIO = 1.8 V while VCC = 3.3 V?

Yes - the S25FL512SAGBHIA13 supports independent VIO (1.65–3.6 V) and VCC (2.7–3.6 V) supplies. At VIO = 1.8 V and VCC = 3.3 V, Quad Read achieves 33 MBps (66 MHz clock), enabling interoperability with 1.8 V FPGAs or microcontrollers while maintaining full core functionality and endurance specifications.
