Infineon Technologies S25FL512SDSBHMC13

Overview

S25FL512SDSBHMC13 from Infineon is a 512 Mb (64 MB) serial NOR flash memory with SPI Multi-I/O interface, 3.0 V core supply (2.7–3.6 V), and 16-pin SOIC package. It supports Quad Read at up to 52 MBps, uniform 256-KB sector erase, 100,000 program-erase cycles, and 20-year data retention. Used in industrial embedded boot storage for microcontrollers requiring fast, reliable nonvolatile code execution.

For engineers reviewing the S25FL512SDSBHMC13 datasheet, S25FL512SDSBHMC13 pinout, S25FL512SDSBHMC13 application, or S25FL512SDSBHMC13 equivalent, this page delivers verified electrical specs, SOIC-16 terminal mapping, CFI/SDP register support, AutoBoot configuration, and OTP-based security implementation - all critical for boot loader integrity and long-life firmware deployment.

Technical Context

This device implements Infineon's 65 nm MIRRORBIT™ technology with Eclipse™ architecture, enabling true single-bit ECC correction via on-die hardware without host intervention. Its SPI interface supports standard and DDR modes (Clock Polarity/Phase 0 & 3), extended 32-bit addressing, and command sets compatible with S25FL-A/K/P families.

The logic block integrates SRAM latches, X/Y decoders, and configurable I/O buffers supporting dual- and quad-I/O read/write operations. Core and I/O supplies are independently rated (VCC: 2.7–3.6 V; VIO: 1.65–3.6 V), allowing interoperability with 1.8 V or 3.3 V host systems while maintaining full performance at VIO ≥ 3.0 V.

FAQ

Does S25FL512SDSBHMC13 support execute-in-place (XIP) operation?

Yes, it supports XIP via Quad Read commands with continuous address increment. The device outputs sequential data on IO0–IO3 without requiring repeated command issuance, enabling direct CPU instruction fetch from flash. This requires host controller SPI controller support for Quad mode and proper address alignment per the datasheet's XIP timing constraints.

What is the function of the RESET# pin, and is it required for normal operation?

RESET# is an asynchronous active-low input that forces the device into a known initial state, clearing internal registers and aborting any ongoing command. It is not required during normal read/write/erase operations but is essential during power-up sequencing or recovery from bus contention errors. Pull-up resistor (10 kΩ) is recommended per datasheet Section 2.3.

How does the AutoBoot feature configure which address is read at power-up?

AutoBoot address is set via the Configuration Register (CR) bits [15:0], programmed using the Write Configuration Register command. The default address is 0x00000000, but users may write any valid 32-bit address within the memory map. AutoBoot triggers automatically after VCC stabilization and RESET# deassertion, executing either Normal or Quad Read based on CR bit [16].

Can the 1024-byte OTP area be reprogrammed after initial programming?

No, the OTP (One-Time Programmable) array is permanently programmed using high-voltage pulses and cannot be erased or rewritten. Once a byte is set to '0', it remains '0'; '1' bits may be changed to '0', but never vice versa. This ensures cryptographic keys and security credentials remain immutable after provisioning.
