Infineon Technologies S25FS064SAGNFI030

Overview

S25FS064SAGNFI030 from Infineon is a 64 Mb (8 MB) serial NOR flash memory IC with SPI Multi-I/O interface, 1.8 V single supply, 133 MHz max clock rate, DDR Quad I/O read up to 80 MBps, and AEC-Q100 Grade 2 automotive qualification (–40°C to +105°C). It integrates hardware ECC, hybrid/uniform sector erase, and OTP security for embedded boot code storage in automotive ADAS controllers.

For engineers reviewing the S25FS064SAGNFI030 datasheet, S25FS064SAGNFI030 pinout, S25FS064SAGNFI030 application, or S25FS064SAGNFI030 equivalent, key selection criteria include SPI-MIO timing compliance, 64 KB/256 KB uniform erase block support, SFDP/CFI configuration capability, industrial-plus temperature operation, and BGA-24 (FAB024) package compatibility.

Technical Context

This device implements Infineon's ECLIPSE architecture with 65-nm MIRRORBIT™ technology, supporting both legacy SPI and QPI modes. It delivers burst-wrap and XIP-capable continuous read, with configurable 24-/32-bit addressing and programmable latency for deterministic timing in real-time systems.

The internal control logic manages dual-bank erase suspend/resume, automatic single-bit ECC correction during read, and multi-layer protection via status register bits, ASP password control, and hardware WP#/RESET# assertion - enabling secure firmware update and boot integrity in safety-critical ECUs.

FAQ

What is the maximum DDR Quad I/O read speed for S25FS064SAGNFI030?

The device achieves 80 MBps DDR Quad I/O read throughput at 80 MHz clock frequency, as specified in Table 1 of the official Infineon datasheet (002-03631 Rev. *I). This requires proper PCB layout with matched trace lengths and controlled impedance for all four I/O lines.

Does S25FS064SAGNFI030 support 32-bit addressing in all operating modes?

Yes - extended 32-bit addressing is supported in both standard SPI and QPI modes, enabling full 64 Mb address space access without bank switching. The mode is selected via configuration register bit CR3[2], and remains active after power-on reset unless reconfigured.

How is hardware write protection implemented on this device?

Hardware write protection is activated by pulling the WP#/IO2 pin low, which locks all status register bits and prevents program/erase commands. This protection persists through power cycles and is independent of software configuration - a critical feature for preventing accidental firmware corruption in deployed systems.

Can S25FS064SAGNFI030 be used in XIP (execute-in-place) mode?

Yes - the device supports continuous read mode with wrap-around burst, enabling true XIP execution from flash memory. This requires QPI mode activation and proper cache coherency handling in the host processor; Infineon provides reference initialization sequences in Application Note AN229032.
