Infineon Technologies S25FL512SAGMFBG13

Overview

S25FL512SAGMFBG13 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 embedded boot code storage in industrial and automotive systems.

For engineers reviewing the S25FL512SAGMFBG13 datasheet, S25FL512SAGMFBG13 pinout, S25FL512SAGMFBG13 application, or S25FL512SAGMFBG13 equivalent, key selection factors include Quad DDR read performance (80 MBps), AEC-Q100 Grade 2 qualification (–40°C to +105°C), OTP security (1024 bytes), uniform sector erase, and SO16/FBGA package compatibility with legacy S25FL-P family designs.

Technical Context

This device implements Infineon's 65 nm MIRRORBIT™ technology with Eclipse™ architecture, enabling high-density nonvolatile storage with single-bit error correction via on-die ECC logic. Its dual-voltage I/O (1.65–3.6 V) and core (2.7–3.6 V) support mixed-signal SoC interfacing while maintaining full command set compatibility with S25FL-A/K/P families.

The logic block integrates SRAM latches, X/Y decoders, and configurable control logic supporting SPI modes 0/3, DDR operation, and programmable AutoBoot address. Sector protection uses both status register bits and Advanced Sector Protection (ASP) with password- or boot-code-controlled individual sector locking.

FAQ

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

The S25FL512SAGMFBG13 supports Quad DDR operation up to 80 MHz, delivering 80 MBps read throughput when VIO = VCC = 3.0–3.6 V. This mode requires precise setup/hold timing and matched trace lengths for all four I/O lines to maintain signal integrity and avoid sampling errors.

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

Yes, the RESET# pin provides asynchronous hardware reset functionality. When asserted low, it clears internal state machines, resets configuration registers to default values, and halts any ongoing command sequence - critical for recovery after brown-out or watchdog timeout events in safety-critical systems.

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

The OTP array is accessed via dedicated JEDEC-standard One Time Program commands (0x4B, 0x42). Once programmed, bits cannot be erased. Protection is enforced by status register lock bits and requires Write Enable (0x06) before programming - preventing accidental overwrite during normal firmware updates.

Can the device operate with VIO = 1.8 V while VCC = 3.3 V?

Yes, the device supports independent I/O and core supplies: VIO may be set from 1.65 V to 2.7 V (including 1.8 V) while VCC remains in its 2.7–3.6 V range. This allows direct interfacing with 1.8 V microcontrollers without level shifters, provided timing margins are verified per AC specifications.
