Infineon Technologies S25FL512SAGBHV310

Overview

S25FL512SAGBHV310 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, SFDP, and operates across –40°C to +105°C (Industrial Plus grade) in FBGA-24 package.

For engineers reviewing the S25FL512SAGBHV310 datasheet, S25FL512SAGBHV310 pinout, S25FL512SAGBHV310 application, or S25FL512SAGBHV310 equivalent, key selection criteria include Quad DDR read performance (80 MBps), 100,000 program-erase cycles, OTP security (1024 bytes), AEC-Q100 Grade 2 qualification, 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 for boot code and firmware storage. Its dual-voltage I/O (VIO = 1.65–3.6 V) allows interoperability with legacy and low-voltage controllers while maintaining full 3.0 V core operation.

The command set supports both SDR and DDR SPI modes, including Fast, Dual, Quad, and DDR variants of Read/Program/Erase operations. Internal hardware ECC provides single-bit error correction without host intervention, and AutoBoot enables automatic execution of Normal or Quad Read at power-up from a user-configurable address.

Compared with S25FL512SAGBHV310, the SOIC variant trades mechanical ruggedness for ease of hand-soldering, while the Winbond alternative sacrifices integrated reliability features for finer erase granularity-neither matches the combined AEC-Q100 Grade 2 qualification, hardware ECC, and AutoBoot of the original.

FAQ

What is the maximum clock frequency supported in DDR mode?

The S25FL512SAGBHV310 supports up to 80 MHz DDR clock frequency, delivering 80 MBps Quad Read DDR throughput when VIO = VCC = 3.0–3.6 V. This requires strict PCB layout adherence to DDR timing constraints, including matched trace lengths and controlled impedance routing for IO0–IO3 lines.

Does this part require external pull-up resistors on WP# and HOLD# pins?

Yes-WP# and HOLD# are active-low inputs with internal weak pull-downs. External 4.7 kΩ pull-up resistors to VIO are required for reliable deassertion during normal operation; omission may cause unintended sector protection or transaction suspension during noise events.

How is the AutoBoot address configured?

The AutoBoot address is stored in the Configuration Register (CR) bits [23:8] and is loaded at power-up or RESET#. It must be programmed via Write Enable + Write Configuration Register command prior to first use; default value is 0x000000, pointing to the start of the memory array.

Is the OTP region one-time programmable only, or can it be erased?

The 1024-byte OTP array is permanently programmable-once a bit is set to '0', it cannot be reset to '1'. Erase is not supported. Programming is performed via dedicated One-Time Program commands and requires Write Enable; each byte must be written individually with proper timing margins.
