Product details

Overview

S25FS064SDSBHI020 from Infineon Technologies is a 64 Mb (8 MB) serial NOR flash memory 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 industrial embedded controllers requiring reliable nonvolatile code storage and XIP execution.

For engineers reviewing the S25FS064SDSBHI020 datasheet, S25FS064SDSBHI020 pinout, S25FS064SDSBHI020 application, or S25FS064SDSBHI020 equivalent, key selection criteria include 1.7–2.0 V operation, AEC-Q100 Grade 2 qualification (–40°C to +105°C), SFDP/CFI support, OTP array size, and DDR Quad I/O timing compliance.

Technical Context

This device implements Infineon's 65-nm MIRRORBIT™ technology with ECLIPSE architecture, enabling high-density, low-voltage NOR flash operation. Its SPI-MIO interface supports legacy SPI modes 0/3, QPI mode, and DDR command/data transfers - all with configurable 24-/32-bit addressing and burst wrap/continuous read modes.

The internal control logic integrates automatic ECC generation, program/erase suspend-resume capability, and dual protection schemes: status-register-based block protection and Advanced Sector Protection (ASP) with password- or boot-code-controlled sector locking. Reset behavior includes both cold (power-on) and warm (RESET#/IO3_RESET# asserted) sequences.

Key Specifications

IO2 (WP#)	Write Protect / Data Line 2	Hardware write-protection enable when pulled low; also serves as quad-mode data line IO2.
IO3 (RESET#)	Reset Input / Data Line 3	Hardware reset trigger (active-low); doubles as quad-mode data line IO3 in MIO operation.
VCC	Power Supply	1.7–2.0 V core and I/O supply; decoupling required per datasheet layout guidelines.
VSS	Ground	Reference return path for all signals and power; requires low-impedance PCB connection.

Key Features

Feature	Design Value
Hardware ECC	On-the-fly single-bit error correction with no software overhead - improves data integrity in noisy environments.

Equivalent & Alternatives

The following parts are listed as comparable options for similar serial NOR flash applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
S25FS064SDBHI020	Same die, BGA-24 (6×8 mm, FAB024) package instead of SOIC; identical electrical specs and timing.	Preferred for space-constrained PCBs with BGA routing capability and thermal management infrastructure.	Select when board layout favors BGA footprint and thermal dissipation exceeds SOIC limits.
S25FL064LDBHI020	Legacy 65 nm FL-L family; lacks DDR mode, max Quad I/O read = 66 MBps, no ASP or OTP array.	Suitable only for cost-sensitive, non-security-critical applications without DDR or advanced protection needs.	Choose only if DDR, ASP, or OTP are not required and legacy driver compatibility is mandatory.

Compared with S25FS064SDBHI020, the SOIC variant offers easier prototyping and rework; versus S25FL064LDBHI020, it delivers higher bandwidth, stronger security, and longer lifecycle support - critical for next-generation certified systems.

FAQ

Is S25FS064SDSBHI020 pin-compatible with earlier S25FL-S devices?

Yes - it maintains identical SOIC-8 pinout and signal definitions with S25FL1-K/S25FL-P/S25FL-S families. Command sets, address mapping, and basic SPI protocols are backward-compatible, though DDR and ASP features require updated host firmware.

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

During active SPI communication, IO3 serves as the fourth I/O line (IO3) in Quad or DDR Quad modes. When asserted low independently, it triggers a hardware warm reset - clearing internal state without cycling VCC, preserving power sequencing integrity in safety-critical systems.

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

Yes - continuous read mode and burst wrap addressing enable true XIP execution. The 80 MBps DDR Quad I/O read rate ensures low-latency instruction fetches, and SFDP registers allow automatic configuration of optimal timing parameters for the host controller.

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

The OTP array resides at fixed address 0x00000000 and is accessed via standard READ/WRITE commands after unlocking via status register write. Once programmed, bits cannot be erased; protection is enforced by hardware - no software override is possible after OTP lock bit is set.
