Product details

Overview

S25FS064SDSNFV033 from Infineon is a 64 Mb (8 MB) serial NOR flash memory IC with SPI Multi-I/O interface, operating at 1.8 V supply. It supports DDR Quad I/O read up to 80 MBps, features hardware ECC for single-bit error correction, and offers hybrid sector erase (eight 4 KB + one 32 KB sectors) plus uniform 64 KB/256 KB block erase options. Used in automotive infotainment boot code storage requiring AEC-Q100 Grade 2 qualification (–40°C to +105°C).

For engineers reviewing the S25FS064SDSNFV033 datasheet, S25FS064SDSNFV033 pinout, S25FS064SDSNFV033 application, or S25FS064SDSNFV033 equivalent, key selection criteria include SPI-MIO timing compliance (DDR Quad I/O at 80 MHz), OTP array size (1024 bytes), SFDP/CFI support for auto-configuration, and AEC-Q100 Grade 2 temperature rating.

Technical Context

This device implements Infineon's 65-nm MIRRORBIT™ technology with ECLIPSE architecture, enabling high-density, low-voltage (1.7–2.0 V) operation and 100,000 program-erase cycles. Its dual-mode SPI interface supports both legacy single-data-rate (SDR) and double-data-rate (DDR) protocols, with QPI mode and burst wrap/continuous XIP read modes enabled via configuration registers.

The logic block integrates dedicated X/Y decoders, SRAM latch-based data path, and on-die ECC generation logic. Sector protection is implemented through status register bits, hardware/software WP# control, and Advanced Sector Protection (ASP) with password-locked read access - all configurable without external controllers.

FAQ

Is S25FS064SDSNFV033 pin-compatible with earlier S25FL-S devices?

Yes - it maintains identical 8-lead SOIC pinout and command subset compatibility with S25FL1-K, S25FL-P, and S25FL-S families. This enables drop-in replacement in existing designs without layout changes, provided voltage and timing margins are verified per the updated AC specifications.

What is the function of the IO3/RESET# pin in normal operation?

In standard SPI mode, IO3 operates as RESET#, providing hardware reset initiation. During Quad I/O operations, it functions as bidirectional I/O3. The pin supports warm reset via pulse assertion while powered, and its dual role is managed automatically by internal logic based on command context and configuration register settings.

Does this device support execute-in-place (XIP) mode?

Yes - it supports continuous read mode for true XIP execution, allowing microcontrollers to fetch and execute code directly from flash without copying to RAM. This mode is enabled via status register bit configuration and requires host controller support for burst wrap addressing and latency management.

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

The OTP array is accessed via dedicated SPI commands (0x4B and 0x42) and resides in a physically isolated memory region. Once programmed, bits cannot be reset. Protection is enforced by status register lock bits and optional password verification before read access - preventing unauthorized extraction of cryptographic keys or calibration data.
