Infineon Technologies S25FL512SAGBHVB10

Overview

S25FL512SAGBHVB10 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, and integrated hardware ECC. It supports Quad Read at up to 52 MBps, AutoBoot, CFI, and operates across –40°C to +105°C (Industrial Plus). Used in boot code storage for embedded microcontrollers and FPGA configuration.

For engineers reviewing the S25FL512SAGBHVB10 datasheet, S25FL512SAGBHVB10 pinout, S25FL512SAGBHVB10 application, or S25FL512SAGBHVB10 equivalent, this page delivers verified electrical specs, package mapping, real-world timing performance, security features (OTP, ASP), and validated alternative parts for migration or sourcing continuity.

Technical Context

This device implements Infineon's 65 nm MIRRORBIT™ technology with Eclipse™ architecture, enabling high-density nonvolatile storage with single-bit ECC correction and deterministic erase/program latency. Its dual-voltage I/O (1.65–3.6 V) and core (2.7–3.6 V) support mixed-signal SoC interfacing without level shifters.

The SPI interface supports all four clock modes (0 and 3 standard), DDR read commands, extended 32-bit addressing, and command sets compatible with S25FL-A/K/P families-ensuring firmware reuse and PCB footprint compatibility across generations.

FAQ

What is the maximum clock frequency supported in DDR mode?

The S25FL512SAGBHVB10 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. DDR timing requires strict setup/hold alignment per AC specification section 5.5.

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

Yes. The WP# pin provides hardware-based write protection: when held low, it blocks all program and erase operations regardless of status register settings. This function remains active even if software write-enable latches are set, offering fail-safe protection against accidental writes.

How is the 1024-byte OTP array used in secure boot implementations?

The OTP array stores immutable keys, certificates, or cryptographic seeds used during secure boot verification. Once programmed, its contents cannot be erased or rewritten. It interfaces directly with boot ROM logic to authenticate firmware signatures before execution, forming the root-of-trust foundation for ASIL-B and SIL-2 systems.

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

Yes. The device 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 performance and reliability.
