Infineon Technologies S25FL512SAGMFVG11

Overview

S25FL512SAGMFVG11 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 supports AutoBoot, CFI, and DDR read modes, and is qualified for Industrial Plus (–40°C to +105°C) operation in SO16 package.

For engineers reviewing the S25FL512SAGMFVG11 datasheet, S25FL512SAGMFVG11 pinout, S25FL512SAGMFVG11 application, or S25FL512SAGMFVG11 equivalent, this device delivers high-speed Quad/DDR read performance, robust data retention (20 years), AEC-Q100 Grade 2 automotive qualification, and flexible I/O voltage (1.65–3.6 V) for embedded boot code and firmware storage in resource-constrained systems.

Technical Context

This SPI NOR flash implements Infineon's 65 nm MIRRORBIT™ technology with Eclipse™ architecture, enabling simultaneous read-while-write capability and deterministic latency via uniform sector erase. Its command set is backward-compatible with S25FL-A/K/P families and supports extended 32-bit addressing for >16 MB memory maps.

The device integrates dual power domains (VCC = 2.7–3.6 V, VIO = 1.65–3.6 V), allowing independent I/O voltage scaling for interfacing with 1.8 V or 3.3 V controllers. Hardware ECC operates transparently during program/erase, eliminating software overhead while ensuring bit-level reliability across 100,000 P/E cycles.

FAQ

What is the maximum clock frequency supported in DDR mode?

The S25FL512SAGMFVG11 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. These rates require VIO = VCC = 3.0–3.6 V and are specified under AC test conditions per datasheet Rev. *U Section 5.5.

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

Yes, the RESET# pin provides hardware reset functionality: asserting it low for ≥20 µs places the device into hardware reset state, clearing internal registers and terminating any ongoing operation. After release, the device enters standby mode and is ready for new commands after tRES1 (100 ns max).

Can the WP# and HOLD# pins be used as general-purpose I/Os?

No - WP# and HOLD# are dedicated function pins with defined roles in SPI protocol. In Quad mode, they serve as IO2 and IO3 for data transfer, but cannot be repurposed as GPIOs. Their behavior is fixed by command mode and cannot be reconfigured via registers or software.

Is the OTP area accessible after programming?

The 1024-byte OTP array is one-time programmable: once a bit is set to '0', it cannot be reverted to '1'. Reads remain fully accessible post-programming, but writes are permanently disabled after initial programming. Access control is enforced by status register bits and requires Write Enable command prior to programming.
