Infineon Technologies S25FL512SDSBHVC13

Overview

S25FL512SDSBHVC13 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 for single-bit error correction. It operates across industrial temperature range (–40°C to +85°C) in 16-pin SOIC package and supports AutoBoot for automatic read at power-up.

For engineers reviewing the S25FL512SDSBHVC13 datasheet, S25FL512SDSBHVC13 pinout, S25FL512SDSBHVC13 application, or S25FL512SDSBHVC13 equivalent, this device delivers high-speed Quad/DDR read modes, OTP-based security, AEC-Q100 Grade 3 qualification, and compatibility with legacy S25FL-A/K/P families - critical for boot code storage and firmware update in resource-constrained embedded systems.

Technical Context

This FL-S series flash implements Infineon's 65 nm MIRRORBIT™ technology with Eclipse™ architecture, enabling true multi-I/O operation (up to Quad and DDR modes) on a standard SPI bus. Its command set supports extended 32-bit addressing, CFI, and JEDEC JESD216 SFDP for auto-configuration.

The device integrates dedicated control logic for AutoBoot execution, hardware-managed ECC, and dual-voltage I/O (VIO = 1.65–3.6 V), allowing interoperability with both 1.8 V and 3.3 V host controllers while maintaining full 512 Mb density and 100,000 program-erase cycles endurance.

FAQ

What is the maximum clock frequency supported for DDR read operations?

The S25FL512SDSBHVC13 supports Fast Read DDR, Dual Read DDR, and Quad Read DDR at up to 80 MHz clock frequency, delivering 20 MBps, 40 MBps, and 80 MBps respectively when VIO = VCC = 3.0–3.6 V. DDR timing requires strict setup/hold compliance per AC specification Table 5.5 in Rev. *U datasheet.

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

Yes, the RESET# pin is an asynchronous active-low input that forces the device into a known initial state, aborting any ongoing command and clearing internal registers. After deassertion, the device resumes normal operation without requiring reinitialization of configuration registers.

How is the AutoBoot address configured?

The AutoBoot address is stored in the Configuration Register (CR) bits [23:8] and is programmed using the Write Configuration Register (WRCR) command. The device executes a Normal or Quad Read command automatically at this address upon power-up or RESET#, depending on CR bit [7].

Is the 1024-byte OTP array permanently locked after programming?

Yes, the OTP array is one-time programmable and irreversible. Once a byte is written (from FFh to any other value), it cannot be erased or rewritten. Programming is performed via the Program OTP command (A1h), and verification is done using the Read OTP command (A2h).
