Infineon Technologies S25FL512SAGMFIG13

Overview

S25FL512SAGMFIG13 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, 100,000 program-erase cycles, and AEC-Q100 Grade 2 qualification (–40°C to +105°C). It supports Quad Read at up to 52 MBps and integrates hardware ECC for single-bit error correction.

For engineers reviewing the S25FL512SAGMFIG13 datasheet, S25FL512SAGMFIG13 pinout, S25FL512SAGMFIG13 application, or S25FL512SAGMFIG13 equivalent, this device is selected for automotive ADAS boot storage, industrial PLC firmware retention, and high-reliability embedded systems requiring extended temperature operation and secure sector protection.

Technical Context

This FL-S family device implements Infineon's 65 nm MIRRORBIT™ technology with Eclipse™ architecture, enabling fast random access and deterministic read latency. It supports SPI clock modes 0 and 3, DDR read commands, and 32-bit extended addressing-enabling direct mapping of full 512 Mb address space without bank switching.

The integrated control logic handles AutoBoot execution on power-up/reset, CFI-compliant configuration data retrieval, and programmable block protection via status register bits or advanced sector protection (ASP) with password- or boot-code-controlled individual sector locking.

FAQ

What is the maximum clock frequency supported for Quad Read operations?

The S25FL512SAGMFIG13 supports Quad Read at up to 104 MHz with VIO = VCC = 2.7–3.6 V, delivering 52 MBps throughput. At reduced I/O voltage (1.65–2.7 V), max Quad Read clock drops to 66 MHz (33 MBps). DDR Quad Read operates at 80 MHz (80 MBps) only when VIO = VCC ≥ 3.0 V.

Does this part support hardware reset-initiated boot loading?

Yes. The AutoBoot feature executes a preconfigured Normal or Quad Read command automatically upon power-up or RESET# assertion. The target address is stored in a dedicated configuration register and persists across power cycles, eliminating need for external boot controller logic.

How is sector protection implemented-via hardware pins or registers?

Sector protection uses both methods: hardware WP# pin enables top/bottom sector lock, while status register bits and Advanced Sector Protection (ASP) allow software-configurable, password- or boot-code-controlled locking of any individual 256-KB sector-providing layered security for firmware partitions.

Is the 20-year data retention specification validated at maximum operating temperature?

Yes. The 20-year minimum data retention is guaranteed across the full industrial-plus temperature range (–40°C to +105°C), verified per JEDEC JESD22-A117 stress testing methodology. No derating is required for Grade 2 operation at +105°C ambient.
