Infineon Technologies S25FL512SAGMFA013

Overview

S25FL512SAGMFA013 from Infineon is a 512 Mb (64 MB) serial NOR flash memory IC 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 automotive 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 S25FL512SAGMFA013 datasheet, S25FL512SAGMFA013 pinout, S25FL512SAGMFA013 application, or S25FL512SAGMFA013 equivalent, key selection factors include Quad DDR read performance (80 MBps), OTP security array (1024 bytes), AutoBoot capability, extended 32-bit addressing, and compatibility with S25FL-P family footprints.

Technical Context

This device implements Infineon's 65 nm MIRRORBIT™ technology with Eclipse™ architecture, enabling high-density nonvolatile storage with deterministic timing and low-power operation. Its dual-voltage I/O (1.65–3.6 V) and core (2.7–3.6 V) support flexible system integration across industrial and automotive platforms.

The logic block includes dedicated SRAM latches, X/Y decoders, and configurable control logic supporting SPI modes 0/3, DDR command execution, and CFI/JEDEC SFDP parameter discovery. Sector erase and page programming are fully hardware-managed with internal ECC generation and verification.

FAQ

Is S25FL512SAGMFA013 pin-compatible with earlier S25FL-A or S25FL-K series devices?

Yes - it maintains identical SOIC-16 pinout and SPI command set compatibility with S25FL-A, S25FL-K, and S25FL-P families. The footprint and signal mapping match exactly, enabling drop-in replacement in existing designs without PCB revision.

Does this device support Quad SPI mode with hardware write protection enabled?

Yes - WP# functions as I/O2 in Quad mode while retaining hardware write protection capability via status register bits. Protection remains active during Quad operations, and sector locks persist across power cycles without external supervision.

What is the maximum clock frequency supported in DDR mode, and what voltage conditions apply?

The device supports Fast Read DDR, Dual Read DDR, and Quad Read DDR at up to 80 MHz, but only when both VIO and VCC are ≥3.0 V. At lower I/O voltages (1.65–2.7 V), DDR mode is not supported per datasheet AC specifications.

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

No - the OTP (One-Time Programmable) array is permanently programmed during final test. Once written, bits cannot be altered or erased. It is intended for immutable data such as cryptographic keys, device IDs, or calibration constants.
