Infineon Technologies S25FL512SDPBHBC13

Overview

S25FL512SDPBHBC13 from Infineon is a 512 Mb (64 MB) SPI NOR flash memory with Multi-I/O interface, 3.0 V core supply (2.7–3.6 V), and 16-pin SOIC package. It supports Quad Read up to 52 MBps, uniform 256-KB sector erase, 100,000 program-erase cycles, and 20-year data retention. Used in industrial microcontroller boot code storage where deterministic read latency and AEC-Q100 Grade 2 temperature operation (–40°C to +105°C) are required.

For engineers reviewing the S25FL512SDPBHBC13 datasheet, S25FL512SDPBHBC13 pinout, S25FL512SDPBHBC13 application, or S25FL512SDPBHBC13 equivalent, key selection criteria include Quad DDR read performance (80 MBps), internal ECC for single-bit correction, OTP security (1024-byte array), and compatibility with S25FL-P family footprint and command set.

Technical Context

This device implements Infineon's 65 nm MIRRORBIT™ technology with Eclipse™ architecture, enabling high-density nonvolatile storage with low-power serial interface operation. It supports SPI clock modes 0 and 3, DDR read commands, and extended 32-bit addressing - critical for systems requiring >16 MB addressable space without bank switching.

The integrated control logic handles automatic ECC generation during programming, uniform sector erase scheduling, and configurable block protection via status register bits or advanced sector protection (ASP) with password/boot-code control. I/O voltage independence (1.65–3.6 V) allows interoperability with 1.8 V or 3.3 V host controllers without level shifters.

FAQ

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

The S25FL512SDPBHBC13 supports Fast Read DDR and Quad Read DDR at up to 80 MHz clock frequency, delivering 80 MBps effective throughput. This requires VIO = VCC = 3.0–3.6 V and proper PCB layout with matched trace lengths for all four I/O lines to maintain signal integrity.

Does this part require external hardware for error correction?

No. The device includes fully autonomous hardware ECC that detects and corrects single-bit errors during every read operation without host intervention or additional components. No external ECC IC or software algorithm is needed for basic error resilience.

Can the OTP array be reprogrammed after initial programming?

No. The 1024-byte OTP (One-Time Programmable) array is permanently programmed using high-voltage pulses and cannot be erased or rewritten. It is intended for immutable data such as cryptographic keys, device identifiers, or calibration constants.

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

Yes. The S25FL512SDPBHBC13 uses a Pb-free 16-pin SOIC package compliant with RoHS Directive 2011/65/EU and JEDEC J-STD-020 moisture sensitivity level 3 (MSL-3), with standard reflow profile compatibility.
