Product details

Overview

S25FS064SAGBHM020 from Infineon 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 options - deployed in industrial and automotive systems requiring reliable nonvolatile code storage and XIP execution.

For engineers reviewing the S25FS064SAGBHM020 datasheet, S25FS064SAGBHM020 pinout, S25FS064SAGBHM020 application, or S25FS064SAGBHM020 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. It supports both legacy SPI and QPI modes, with configurable 24-/32-bit addressing and burst wrap/continuous read for XIP capability.

The control logic integrates automatic ECC generation, program/erase suspend-resume, and dual protection schemes: status-register-based block protection plus Advanced Sector Protection (ASP) with password- or boot-code-controlled sector locking and optional read-access restriction.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Size	64 Mb (8 MB) - sufficient for firmware images, boot code, and configuration data in resource-constrained embedded hosts.
Supply Voltage	1.7 V to 2.0 V - compatible with low-power 1.8 V system rails and reduces active current vs. 3.3 V flash.
Max Read Rate	80 MBps (DDR Quad I/O) - enables fast code fetch for real-time XIP execution without external RAM buffering.
Endurance	100,000 program-erase cycles - supports field firmware updates over extended product lifetimes.
Data Retention	20 years minimum - ensures long-term reliability in unpowered storage across automotive and industrial deployments.
Erase Options	Hybrid (4 KB/32 KB) and uniform (64 KB/256 KB) sectors - balances fine-grained update flexibility with legacy software compatibility.
Security	1024-byte OTP array + ASP with password-controlled read lock - prevents unauthorized firmware extraction or modification.

Pinout & Package

Package: 24-ball BGA (6 × 8 mm, FAB024 footprint), RoHS-compliant, suitable for high-density PCB layouts and automotive thermal cycling.

Pin/Terminal	Circuit Role	Design Meaning
CS#	Chip Select	Active-low enable for command/address/data transfer; must be asserted before each SPI transaction.
SCK	Serial Clock	Provides timing reference for all SPI transfers; supports up to 133 MHz SDR or 80 MHz DDR operation.
IO0–IO3	Multi-I/O Data Lines	Bi-directional pins supporting single/dual/quad I/O protocols; IO3 doubles as RESET# input in standard mode.
WP#	Write Protect	Hardware-enabled sector protection override; tied low to prevent accidental program/erase during power transients.
VCC / VSS	Power / Ground	Single 1.8 V supply rail with dedicated ground plane; decoupling required per layout guidelines for signal integrity.

Key Features

Feature	Design Value
Hardware ECC	On-the-fly single-bit error correction with no CPU overhead - maintains data integrity without software intervention.
DDR Quad I/O Interface	80 MBps read throughput using double-data-rate on four I/O lines - cuts latency vs. standard SPI by >2× at same clock frequency.
Hybrid Sector Architecture	Eight 4 KB + one 32 KB sectors at top/bottom address space - enables safe bootloader storage with independent protection.
Advanced Sector Protection (ASP)	Password- or boot-ROM-controlled sector locking - enforces secure firmware partitioning and prevents unauthorized access to critical code regions.
SFDP & CFI Support	Standardized parameter tables readable via SPI - allows automatic driver initialization and eliminates hard-coded timing assumptions.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
S25FS128SAGBHM020	128 Mb density, identical pinout and command set - requires no layout change but doubles capacity.	Used when future firmware growth headroom or dual-image redundancy is required.	Select if design anticipates >8 MB firmware expansion without board revision.
MX25L6433FZNI-10G	64 Mb, 3.3 V operation, no DDR mode, lower max read rate (40 MBps), no ASP or OTP.	Legacy industrial designs lacking voltage scaling or security requirements.	Choose only for cost-sensitive, non-automotive applications where 1.8 V and advanced protection are unnecessary.

Compared with S25FS064SAGBHM020, the S25FS128S offers seamless scalability within the same family, while MX25L6433F trades security, speed, and voltage efficiency for legacy compatibility and lower unit cost - making it unsuitable for AEC-Q100 or secure boot use cases.

FAQ

Is S25FS064SAGBHM020 pin-compatible with earlier S25FL-S series devices?

Yes - it maintains identical 24-ball BGA (FAB024) footprint and SPI command subset compatibility with S25FL1-K, S25FL-P, and S25FL-S families. Pin functions, timing, and register maps align, enabling drop-in replacement where voltage and temperature requirements match.

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

Yes - continuous read mode and burst wrap addressing allow direct code execution from flash without copying to RAM. QPI mode further enhances XIP performance by reducing instruction overhead, and SFDP provides auto-configurable timing parameters for host driver initialization.

What is the function of the IO3/RESET# pin?

IO3 serves dual roles: as a quad I/O data line in normal operation and as an active-low hardware reset input (RESET#) when configured via status register. This enables in-system recovery without external reset circuitry, and the pin remains functional during deep power-down mode.

How does Advanced Sector Protection (ASP) differ from standard block protection?

Standard block protection uses status register bits to lock contiguous sectors globally. ASP adds granular, individual-sector control via boot ROM or password - enabling selective lockdown of bootloader, calibration, or crypto key regions independent of other sectors, with optional password-gated read access enforcement.
