Product details

Overview

S25FS064SAGBHB020 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) alongside uniform 64 KB/256 KB block erase options. Used in industrial microcontroller boot code storage requiring high reliability and fast XIP-capable reads.

For engineers reviewing the S25FS064SAGBHB020 datasheet, S25FS064SAGBHB020 pinout, S25FS064SAGBHB020 application, or S25FS064SAGBHB020 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 hybrid vs. uniform sector erase configuration flexibility.

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 Quad I/O with configurable 24-/32-bit addressing - critical for memory-mapped execution in resource-constrained embedded systems.

The internal control logic integrates automatic ECC generation, program/erase suspend-resume capability, and dual protection schemes: status-register-based block protection plus Advanced Sector Protection (ASP) with password-controlled read access. These features enable secure, field-upgradable firmware storage in automotive and industrial controllers.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
S25FS128SAGBHI20	128 Mb density, identical package and pinout, same 1.8 V operation and AEC-Q100 Grade 2 rating	Requires larger PCB footprint only if higher capacity is needed; otherwise drop-in compatible for future-proofing	Select when firmware image size exceeds 8 MB or when design requires headroom for feature expansion
MX25L6433FZNI-10G	64 Mb, 3 V operation (2.7–3.6 V), no DDR support, no ASP or OTP array, lower endurance (50K cycles)	Lacks automotive qualification, security features, and high-speed DDR read - suitable only for cost-sensitive consumer applications	Choose only for non-automotive, non-industrial designs where voltage margin and security are not required

Compared with S25FS064SAGBHB020, the S25FS128SAGBHI20 offers seamless scalability within the same family, while the MX25L6433FZNI-10G sacrifices automotive qualification, ECC, and security for lower unit cost - making it unsuitable for safety-critical or long-lifecycle deployments.

FAQ

What is the maximum clock frequency supported in DDR Quad I/O mode?

The S25FS064SAGBHB020 supports up to 80 MHz in DDR Quad I/O mode, delivering 80 MBps effective read throughput. This is specified in Table 1 of the datasheet and validated across the full industrial temperature range (–40°C to +105°C). The device uses DLP (Dual Latency Pulse) timing to maintain setup/hold margins at this rate.

Does this part support both 24-bit and 32-bit addressing?

Yes, the S25FS064SAGBHB020 supports extended addressing with configurable 24-bit or 32-bit address modes. This is implemented via the Extended Address Register (EAR) and enables compatibility with legacy 24-bit systems while allowing future expansion into larger address spaces without hardware changes.

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

The OTP array is accessed via dedicated SPI commands (0x4B and 0x4C) and is permanently locked after programming using the OTP Lock Bit in the Configuration Register. Once locked, no further writes or erases are possible - ensuring cryptographic keys or calibration data remain immutable throughout the device's lifetime.

Can the hybrid sector erase option be disabled in favor of uniform 64 KB sectors only?

Yes, the device supports uniform sector erase mode via Configuration Register bit CR3[1]. When set, all sectors operate as 64 KB blocks, disabling the top/bottom hybrid layout. This mode improves software compatibility with existing drivers written for earlier S25FL families and simplifies erase scheduling in deterministic real-time systems.
