Product details

Overview

S25FL512SAGBHA210 from Infineon is a 512 Mb (64 MB) serial NOR flash memory with SPI Multi-I/O interface, 3.0 V core supply, uniform 256-KB sectors, Quad Read up to 52 MBps, and integrated hardware ECC for single-bit error correction. It operates across industrial temperature range (–40°C to +85°C) in FBGA-24 package and is used for firmware storage in embedded controllers and boot code execution in automotive ECUs.

For engineers reviewing the S25FL512SAGBHA210 datasheet, S25FL512SAGBHA210 pinout, S25FL512SAGBHA210 application, or S25FL512SAGBHA210 equivalent, key selection factors include Quad DDR read speed (80 MBps), AEC-Q100 Grade 3 qualification, OTP security array (1024 bytes), and compatibility with S25FL-P family footprint and command set.

Technical Context

This device implements Infineon's 65 nm MIRRORBIT™ technology with Eclipse™ architecture, enabling high-density nonvolatile storage with deterministic timing and low-power operation. Its dual-voltage I/O (VIO = 1.65–3.6 V) supports mixed-signal SoC interfacing while maintaining full SPI command compatibility across legacy FL-S families.

The control logic integrates AutoBoot functionality-configurable to execute Normal or Quad Read at power-up-and supports both standard SPI modes (0/3) and DDR mode with extended 32-bit addressing. CFI and JEDEC JESD216 SFDP tables provide runtime configuration discovery for host bootloaders.

Key Specifications

Parameter	Value and Actual Design Meaning
Density	512 Mb (64 MB) - sufficient for full firmware images including bootloader, OS kernel, and application binaries in resource-constrained embedded systems
Read Speed (Quad)	52 MBps at 104 MHz - enables sub-100 ms firmware load time for 4 MB image, critical for fast-boot automotive modules
Erase Unit	Uniform 256-KB sectors - simplifies wear leveling and avoids fragmentation in OTA update partitions
Endurance	100,000 program-erase cycles - supports frequent field updates over 10+ years of automotive service life
Data Retention	20 years minimum - ensures firmware integrity across vehicle lifetime without refresh
Security	1024-byte OTP + ASP - allows secure key storage and per-sector password protection for bootloader authentication
Supply Range	VCC: 2.7–3.6 V; VIO: 1.65–3.6 V - enables direct interfacing with 1.8 V or 3.3 V host processors without level shifters

Pinout & Package

Package: 24-ball FBGA (FAB024, 6 × 8 mm, 0.8 mm pitch), Pb-free, RoHS-compliant.

Pin/Terminal	Circuit Role	Design Meaning
CS#	Chip Select	Active-low enable for SPI command decoding; must be asserted before SCK edge to initiate transaction
SCK	Serial Clock	Input clock for SDR (modes 0/3) or DDR; max 133 MHz SDR / 80 MHz DDR for full performance compliance
IO0	Serial Input / I/O0	Primary data line for standard SPI; functions as bidirectional quad I/O lane in QPI mode
IO1	Serial Output / I/O1	Default SO in standard mode; becomes second quad I/O lane in QPI; supports dual/quad read/write
IO2	Write Protect / I/O2	Hardware write protection enable when WP# is low; also serves as third quad I/O lane in QPI
IO3	Hold / I/O3	Pauses ongoing transaction when HOLD# is low; doubles as fourth quad I/O lane in QPI
RESET#	Hardware Reset	Asynchronous active-low reset that clears internal state and reinitializes flash controller logic
VCC	Core Supply	2.7–3.6 V power for memory array and control logic; decoupling required within 10 mm of pad
VIO	I/O Supply	1.65–3.6 V supply for all I/O pins; independent of VCC to support mixed-voltage host interfaces
VSS	Ground	Common reference for VCC and VIO; requires low-inductance connection to PCB ground plane

Key Features

Feature	Design Value
AutoBoot Execution	Configurable automatic Quad Read at power-up or reset from user-defined address - eliminates external boot ROM and reduces BOM count
Hardware ECC	On-the-fly single-bit error correction with no software overhead - maintains data integrity without CPU intervention during reads
Advanced Sector Protection (ASP)	Password- or boot-code-controlled individual sector locking - prevents unauthorized firmware modification in safety-critical ECUs
JEDEC JESD216 SFDP Support	Runtime discoverable parameters (read latency, erase sizes, voltage ranges) - enables generic flash drivers across multiple vendors
Quad-Input Page Programming (QPP)	4-lane parallel programming for slow-clock hosts - achieves full 1.5 MBps write throughput even at 20 MHz SCK

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
Cypress S25FL512SDSBHI210	Same die, identical electrical specs and pinout; differs only in marking and tape-and-reel packaging	No functional difference; suitable for drop-in replacement where packaging logistics allow	Select when sourcing from legacy Cypress channel or requiring specific reel orientation
Winbond W25Q512JWIM > 210	512 Mb density, 1.8 V I/O compatible, but lacks AutoBoot and ASP; uses different SFDP layout	Requires host-side boot management; not AEC-Q100 qualified; lower security assurance	Choose for cost-sensitive industrial designs where automotive qualification and advanced protection are unnecessary

Compared with S25FL512SAGBHA210, the Cypress alternative offers identical functionality with packaging variance, while the Winbond part trades security and automotive compliance for broader I/O voltage flexibility and lower unit cost in non-safety-critical applications.

FAQ

What is the maximum clock frequency supported in DDR mode?

The S25FL512SAGBHA210 supports up to 80 MHz in DDR mode, delivering 80 MBps Quad Read DDR throughput when VIO and VCC are both ≥3.0 V. This is validated per datasheet Rev. *U Section 3, Table on page 3. Operation above 80 MHz DDR is not guaranteed and may result in timing violations or data corruption.

Does this part support 32-bit addressing in all command modes?

Yes - extended 32-bit addressing is supported in all read, program, and erase commands via the 4-Byte Address Instruction (0xB7/0xE9), enabling full access to the entire 512 Mb array without bank switching. This is mandatory for firmware images exceeding 16 MB and is compliant with JEDEC JESD216B SFDP v1.6.

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

The OTP array is accessed via dedicated One-Time-Program commands (0x4B/0x42) and is permanently locked after first write to any byte. Protection is enforced by status register bit SRP0/SRP1 and hardware fuse; once programmed, OTP contents cannot be erased or rewritten, ensuring cryptographic key immutability.

Can the device operate with VIO = 1.8 V while VCC = 3.3 V?

Yes - the device supports independent VIO (1.65–3.6 V) and VCC (2.7–3.6 V) supplies. At VIO = 1.8 V and VCC = 3.3 V, Quad Read is limited to 33 MBps (66 MHz SCK), and DDR mode is disabled. All DC and AC specifications for this condition are fully characterized in datasheet Section 4.5 and Table on page 3.
