Infineon Technologies S25FL512SDPMFIG10

Overview

S25FL512SDPMFIG10 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, 100,000 program-erase cycles, and AEC-Q100 Grade 2 automotive qualification (–40°C to +105°C). It supports Quad Read at up to 52 MBps and integrates hardware ECC for single-bit error correction.

For engineers reviewing the S25FL512SDPMFIG10 datasheet, S25FL512SDPMFIG10 pinout, S25FL512SDPMFIG10 application, or S25FL512SDPMFIG10 equivalent, this device is selected for boot code storage in automotive ADAS ECUs, industrial PLC firmware, and secure IoT edge node configuration where DDR-capable SPI bandwidth, long data retention, and sector-level protection are required.

Technical Context

This FL-S series flash implements Infineon's 65 nm MIRRORBIT™ technology with Eclipse™ architecture, enabling true multi-I/O operation across SI/IO0, SO/IO1, WP#/IO2, and HOLD#/IO3 pins. It supports all standard SPI modes (0 and 3), DDR read commands, and extended 32-bit addressing for full 512 Mb access without bank switching.

The device integrates dedicated control logic for AutoBoot execution on power-up/reset, CFI-compliant configuration registers, and a 512-byte page programming buffer with Quad-Input Page Programming (QPP) support-enabling efficient writes even under low-clock microcontroller interfaces.

FAQ

What is the maximum clock frequency supported for Quad DDR reads?

The S25FL512SDPMFIG10 supports Quad Read DDR at up to 80 MHz, delivering 80 MBps throughput when VIO = VCC = 3.0–3.6 V. This requires proper setup of the DDR enable bit in the configuration register and matching host controller timing margins per datasheet Section 5.5.

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

Yes, the RESET# pin provides asynchronous hardware reset functionality. When asserted low, it aborts any ongoing operation, clears internal state, and returns the device to standby mode. After release, the device remains in reset until VCC and VIO stabilize and the internal power-on reset circuit releases.

How is the 1024-byte OTP array protected from accidental overwrite?

The OTP array is protected by a one-time programmable fuse that permanently disables further writes after initial programming. Access requires first issuing the Write Enable command and setting the appropriate OTP lock bits in the status register; once fused, no command can re-enable write access to that region.

Can the device operate with VIO = 1.8 V while VCC = 3.3 V?

Yes, the S25FL512SDPMFIG10 supports independent VIO (1.65–3.6 V) and VCC (2.7–3.6 V) supplies. At VIO = 1.8 V and VCC = 3.3 V, Quad Read operates at up to 33 MBps (66 MHz clock), and all control signals (CS#, SCK, WP#, HOLD#) are referenced to VIO, ensuring safe interfacing with 1.8 V logic families.
