Infineon Technologies S25FL512SAGBHAC13

Overview

S25FL512SAGBHAC13 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, and DDR read modes, and is qualified for Industrial Plus (–40°C to +105°C) operation in FBGA package.

For engineers reviewing the S25FL512SAGBHAC13 datasheet, S25FL512SAGBHAC13 pinout, S25FL512SAGBHAC13 application, or S25FL512SAGBHAC13 equivalent, key selection criteria include Quad/DDR read bandwidth, 100K P/E cycle endurance, OTP security, sector protection granularity, and AEC-Q100 Grade 2 qualification for extended-temperature embedded systems.

Technical Context

This device implements Infineon's 65 nm MIRRORBIT™ technology with Eclipse™ architecture, enabling high-density nonvolatile storage with deterministic timing and low-latency command execution. Its dual-voltage I/O (VIO = 1.65–3.6 V) decouples interface signaling from core logic, supporting mixed-voltage host designs without level shifters.

The SPI interface supports all four clock polarity/phase modes (0 and 3), DDR read commands, and extended 32-bit addressing-enabling seamless migration from legacy S25FL-A/K/P families while maintaining footprint compatibility with S25FL-P devices.

FAQ

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

The S25FL512SAGBHAC13 supports Fast Read DDR, Dual Read DDR, and Quad Read DDR at up to 80 MHz clock rate, delivering 20 MBps, 40 MBps, and 80 MBps respectively-provided VIO and VCC are both ≥3.0 V. DDR timing requires precise setup/hold margins and is validated per AC specification section 5.5 of the datasheet.

Does this part support hardware reset via the RESET# pin, and what is its behavior?

Yes, the RESET# pin provides asynchronous hardware reset. When asserted low, it aborts any ongoing command, clears internal state machines, and returns the device to standby mode with status register bits reset to default values. Release of RESET# initiates internal power-on reset sequence before accepting new commands.

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

The OTP array is accessed via dedicated JEDEC-standard One-Time-Program commands (0x4B, 0x42). Once programmed, bits cannot be erased. Protection is enforced by status register lock bits and hardware fuse-OTP programming is disabled after initial write unless specific unlock sequences are executed, preventing accidental overwrite.

Can the device operate with VIO = 1.8 V while VCC = 3.3 V, and what performance impact does this have?

Yes, VIO can be independently set from 1.65 V to 2.7 V while VCC remains 2.7–3.6 V. At VIO = 1.8 V, maximum Quad Read speed drops to 33 MBps (66 MHz clock), and Fast Read is limited to 8.25 MBps. All other functionality-including programming, erase, and security features-remains fully operational.
