Infineon Technologies S25FL512SDSBHI210

Overview

S25FL512SDSBHI210 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 extended 32-bit addressing for boot code storage in embedded controllers and FPGA configuration.

For engineers reviewing the S25FL512SDSBHI210 datasheet, S25FL512SDSBHI210 pinout, S25FL512SDSBHI210 application, or S25FL512SDSBHI210 equivalent, key selection criteria include Quad DDR read performance (80 MBps), 100,000 program-erase cycles, AEC-Q100 Grade 2 qualification (–40°C to +105°C), OTP security, and SOIC-16 package compatibility with legacy S25FL-A/K/P families.

Technical Context

This device implements Infineon's 65 nm MIRRORBIT™ technology with Eclipse™ architecture, enabling high-density nonvolatile storage with deterministic timing and low-power operation. Its dual-voltage I/O (1.65–3.6 V) and core (2.7–3.6 V) support flexible system integration across industrial and automotive platforms.

The command set includes full backward compatibility with S25FL-A/K/P families and extends functionality via DDR modes, AutoBoot execution at power-up/reset, and Advanced Sector Protection (ASP) with password- or boot-code-controlled sector locking - all managed through standard SPI protocols without external logic.

FAQ

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

The S25FL512SDSBHI210 supports Quad DDR read operations at up to 80 MHz, delivering 80 MBps throughput when VIO = VCC = 3.0–3.6 V. This mode requires strict PCB layout adherence to differential clock routing rules and proper termination to maintain signal integrity across the SPI bus.

Does this device require external hardware for ECC correction?

No. The device includes fully integrated hardware ECC that automatically detects and corrects single-bit errors during read operations without CPU involvement or external circuitry. No additional components or firmware drivers are needed to enable this feature - it operates transparently on every read access.

Can the AutoBoot address be reprogrammed in the field?

Yes. The AutoBoot address is stored in a dedicated configuration register (CR3[7:0]) and can be updated via standard SPI Write Register commands. Changes persist across power cycles and do not require OTP programming - enabling dynamic boot source selection during firmware updates or recovery sequences.

Is the SOIC-16 package RoHS-compliant and lead-free?

Yes. The S25FL512SDSBHI210 uses a Pb-free, RoHS-compliant 16-pin SOIC package with matte tin plating. It meets JEDEC J-STD-020 moisture sensitivity level 3 (MSL-3) and is qualified for reflow soldering per IPC/JEDEC J-STD-020 standards without special handling requirements.
