Infineon Technologies S25FL512SAGBHMC10

Overview

S25FL512SAGBHMC10 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, Quad Read up to 52 MBps, and integrated hardware ECC for single-bit error correction. It operates across industrial temperature range (–40°C to +85°C) in SO16 package and supports AutoBoot, CFI, and JEDEC SFDP.

For engineers reviewing the S25FL512SAGBHMC10 datasheet, S25FL512SAGBHMC10 pinout, S25FL512SAGBHMC10 application, or S25FL512SAGBHMC10 equivalent, key selection criteria include Quad DDR read performance (80 MBps), OTP security (1024-byte array), AEC-Q100 Grade 3 qualification, sector protection granularity, and compatibility with S25FL-P family footprint and command set.

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 while maintaining full SPI command compatibility across legacy FL-A/K/P families.

The logic block integrates SRAM latches, X/Y decoders, and dedicated control logic for simultaneous address decoding and data path management. All read, program, and erase operations are managed by on-die state machines with automatic ECC generation and verification-no host software intervention required for bit-error recovery.

FAQ

What is the maximum Quad DDR read speed supported by S25FL512SAGBHMC10?

The device achieves 80 MBps Quad DDR read speed at 80 MHz clock rate with VIO = VCC = 3.0–3.6 V. This requires proper setup of DDR mode via configuration register and matching controller timing margins. Performance drops to 33 MBps under 1.65–2.7 V I/O conditions due to reduced signal slew rate.

Does S25FL512SAGBHMC10 support hardware reset via the RESET# pin?

Yes, the RESET# pin is an active-low asynchronous input that forces the device into hardware reset state, clearing internal registers and aborting any ongoing operation. After deassertion, the device enters standby mode and waits for CS# assertion to resume normal operation-no reinitialization sequence is required.

How does the AutoBoot feature function without external configuration?

AutoBoot is configured using nonvolatile bits in the configuration register. Once programmed, the device automatically executes a Normal or Quad Read command at a user-defined address upon power-up or RESET#. No host processor interaction is needed, making it ideal for systems with minimal boot firmware.

Can S25FL512SAGBHMC10 be used in place of older S25FL-P series devices?

Yes-this part is pin-compatible and command-set compatible with S25FL-P devices, including identical SO16 footprint and register mapping. Migration requires no PCB change and minimal firmware update, primarily to leverage enhanced features like AutoBoot, ASP, and improved DDR timing margins.
