Infineon Technologies S25FL512SAGMFI013

Overview

S25FL512SAGMFI013 from Infineon is a 512 Mb (64 MB) serial NOR flash memory with SPI Multi-I/O interface, 3.0 V core supply, and uniform 256-KB sector architecture. It supports Quad Read at up to 52 MBps, features internal hardware ECC, 100,000 program-erase cycles, and operates across –40°C to +105°C (Industrial Plus grade). Used for firmware storage in industrial controllers requiring high reliability and fast boot.

For engineers reviewing the S25FL512SAGMFI013 datasheet, S25FL512SAGMFI013 pinout, S25FL512SAGMFI013 application, or S25FL512SAGMFI013 equivalent, key selection criteria include Quad DDR read performance (80 MBps), OTP security array size (1024 bytes), AEC-Q100 Grade 2 qualification, and SO16/FBGA package compatibility with legacy S25FL-P designs.

Technical Context

This device implements Infineon's 65 nm MIRRORBIT™ technology with Eclipse™ architecture, enabling true single-bit ECC correction without software overhead. Its command set is fully compatible with S25FL-A/K/P families, supporting both standard SPI modes 0/3 and DDR operation with 32-bit extended addressing.

The dual-voltage I/O interface (VIO = 1.65–3.6 V, VCC = 2.7–3.6 V) allows interoperability with 1.8 V and 3.3 V host controllers. AutoBoot functionality enables automatic execution of Normal or Quad Read at power-up or reset from a preselected address, reducing boot latency in embedded systems.

FAQ

What is the maximum clock frequency supported in DDR mode?

The S25FL512SAGMFI013 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. This is specified in the AC characteristics section of the datasheet under DDR timing parameters.

Does this part support hardware reset via the RESET# pin?

Yes, the RESET# pin is an active-low hardware reset input that forces the device into a known state, clearing internal registers and aborting any ongoing command. It is electrically compatible with standard microcontroller reset outputs and requires no external pull-up resistor per datasheet recommendations.

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

The OTP array is accessed using dedicated JEDEC-standard One Time Program commands (0x4B and 0x42). Once programmed, bits cannot be erased. Protection is enforced by status register lock bits and requires Write Enable before programming - preventing accidental writes during normal operation or field updates.

Can the SO16 package operate across the full Industrial Plus temperature range?

Yes, the S25FL512SAGMFI013 in 16-pin SOIC package is fully qualified for –40°C to +105°C (Industrial Plus grade), with all electrical specifications guaranteed across this range. Thermal resistance (θ_JA) is 110°C/W, and derating curves confirm stable operation at maximum ambient temperature with standard PCB copper area.
