Infineon Technologies S25FL512SAGBHID13

Overview

S25FL512SAGBHID13 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-Input Page Programming, and hardware ECC. It supports Fast/Quad/Dual/DDR read modes up to 80 MHz DDR clock (80 MBps Quad Read DDR), operates from –40°C to +105°C (Industrial Plus), and is used in boot code storage for network routers and industrial HMIs.

For engineers reviewing the S25FL512SAGBHID13 datasheet, S25FL512SAGBHID13 pinout, S25FL512SAGBHID13 application, or S25FL512SAGBHID13 equivalent, key selection criteria include sector erase uniformity, AutoBoot capability at power-up, CFI/SFDP compliance, OTP security array size, and VIO voltage flexibility (1.65–3.6 V).

Technical Context

This FL-S series flash implements Infineon's 65 nm MIRRORBIT™ technology with Eclipse™ architecture, enabling single-bit ECC correction and 100,000 program-erase cycles. Its dual-voltage design separates core (VCC: 2.7–3.6 V) and I/O (VIO: 1.65–3.6 V) rails, supporting mixed-signal SoC interfacing without level shifters.

The device supports extended 32-bit addressing, SPI clock modes 0 and 3, and command sets compatible with S25FL-A/K/P families. AutoBoot executes preconfigured Normal or Quad Read at power-on reset, while Advanced Sector Protection enables password- or boot-code-controlled individual sector locking.

FAQ

What is the maximum supported SPI clock frequency for Quad Read DDR mode?

The S25FL512SAGBHID13 supports Quad Read DDR at up to 80 MHz clock frequency, delivering 80 MBps effective throughput when VIO = VCC = 3.0–3.6 V. This requires strict adherence to DDR timing windows specified in Section 5.5 of the datasheet, including setup/hold margins for double-data-rate sampling on both rising and falling edges.

Does this part support JEDEC JESD216 SFDP for automatic configuration detection?

Yes, the S25FL512SAGBHID13 implements JEDEC JESD216 serial flash discoverable parameters (SFDP) in its dedicated address space (0xFFFFFF00–0xFFFFFFFF). The SFDP table provides standardized descriptors for density, timing, erase block structure, and command sets, enabling automatic driver initialization without hard-coded parameters.

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

The OTP array is accessed via dedicated One-Time-Program commands (0x4B, 0x42) and resides at fixed address 0x00000000 in the OTP address space. Once programmed, bits cannot be reset. Protection is enforced by Status Register Lock Bit (SRP) and hardware write-protection pins (WP#), preventing accidental writes during normal operation or power transients.

Can AutoBoot be configured to execute Quad Read from any arbitrary address?

AutoBoot executes from one of two preselected addresses: 0x00000000 (default) or a user-defined address stored in the Configuration Register (CR3[7:0] and CR4[7:0]). The target address must be aligned to a 256-KB sector boundary and reside within the main array. Configuration requires issuing Write Enable and Write Configuration Register commands before power cycle.
