Product details

Overview

S25FL512SDSMFB013 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 supports AutoBoot, CFI, and DDR read modes, and is qualified for Industrial Plus (–40°C to +105°C) operation in FBGA package.

For engineers reviewing the S25FL512SDSMFB013 datasheet, S25FL512SDSMFB013 pinout, S25FL512SDSMFB013 application, or S25FL512SDSMFB013 equivalent, this device delivers high-speed Quad/DDR read performance, robust data retention (20 years), 100,000 program-erase cycles, OTP security, and AEC-Q100 Grade 2 automotive qualification - critical for boot code storage in embedded controllers and ADAS ECUs.

Technical Context

This FL-S series flash implements Infineon's 65 nm MIRRORBIT™ technology with Eclipse™ architecture, enabling simultaneous read-while-write capability and deterministic latency via uniform sector erase. Its dual-voltage I/O (1.65–3.6 V) and core (2.7–3.6 V) support flexible host interfacing across industrial and automotive platforms.

The device uses standard SPI command sets compatible with S25FL-A/K/P families and extends functionality with Quad Input Page Programming (QPP), Fast/Quad/DDR read variants, and Advanced Sector Protection (ASP) controlled by boot code or password - enabling secure, field-upgradable firmware storage without external logic.

Key Specifications

Parameter	Value and Actual Design Meaning
Density	512 Mb (64 MB) - sufficient for full firmware images including bootloader, OS, and application binaries in resource-constrained microcontrollers.
Read Speed (Quad)	52 MBps at 104 MHz (VIO = VCC = 3.0–3.6 V) - enables sub-100 ms full-image reads for fast boot recovery and OTA update verification.
Erase Unit	Uniform 256-KB sectors - simplifies partitioning for secure firmware updates and eliminates wear-leveling complexity in bare-metal systems.
Endurance	100,000 program-erase cycles - supports frequent field updates in telematics gateways and industrial PLCs over 10+ year lifetimes.
Data Retention	20 years minimum - ensures long-term reliability of stored calibration data and configuration parameters in automotive ECU modules.
Security	1024-byte OTP array + ASP + Status Register block protection - provides immutable root-of-trust storage and per-sector write lock for ISO 21434-compliant systems.
Temperature Range	–40°C to +105°C (Industrial Plus) - validated for under-hood automotive applications without derating or thermal management overhead.

Pinout & Package

Package: 24-ball FBGA (FAB024 footprint, 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 valid transactions.
SCK	Serial Clock	Input clock driving all SPI operations; supports up to 133 MHz SDR and 80 MHz DDR modes for timing-critical boot sequences.
IO0 (SI)	Serial Input / I/O0	Primary data input for commands and addresses; also serves as first I/O line in Dual/Quad modes for bidirectional high-throughput transfers.
IO1 (SO)	Serial Output / I/O1	Primary data output during reads; functions as second I/O line in Dual/Quad modes to double or quadruple effective bandwidth.
IO2 (WP#)	Write Protect / I/O2	Hardware-enabled sector lock control; when tied low, prevents program/erase of protected sectors independent of software commands.
IO3 (HOLD#)	Hold / I/O3	Pauses ongoing SPI transfer without deselecting device; preserves internal state during host interrupt handling or bus arbitration.
VCC	Core Supply	2.7–3.6 V power for memory array and control logic; decoupling required within 10 mm of pin per layout guidelines.
VIO	I/O Supply	1.65–3.6 V voltage setting logic levels for IO0–IO3; allows direct interfacing with 1.8 V or 3.3 V host MCUs without level shifters.
RESET#	Hardware Reset	Asynchronous active-low reset that clears internal state and forces re-initialization - essential for fail-safe recovery after brownout or watchdog timeout.

Key Features

Feature	Design Value
AutoBoot	Automatically executes Normal or Quad Read at power-up/reset from preconfigured address - eliminates host-side boot initialization delay and reduces BOM count.
Hardware ECC	On-the-fly single-bit error correction with no CPU overhead - maintains data integrity across temperature cycling and radiation exposure in automotive environments.
Quad Input Page Programming (QPP)	Enables page programming using all four I/O lines even at low clock frequencies (<20 MHz) - improves programming throughput in low-power MCU subsystems.
Common Flash Interface (CFI)	Standardized register-based query mechanism providing runtime-accessible geometry, timing, and feature flags - simplifies portable flash driver development across toolchains.
Advanced Sector Protection (ASP)	Password- or boot-code-controlled individual sector locking - enforces secure firmware update policies without requiring external secure elements or TPMs.

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 S25FL512SAGMFI000	Same die, identical electrical specs and pinout; differs only in marking and packaging (tray vs. tape-and-reel).	No functional difference; both qualified for Industrial Plus and AEC-Q100 Grade 2.	Select based on logistics preference - S25FL512SDSMFB013 is tape-and-reel optimized for SMT production.
Winbond W25Q512JWIM > 256KB sectors	512 Mb density, but uses 4-KB and 64-KB sectors (not uniform 256-KB); lacks AutoBoot and ASP features.	Suitable for general-purpose code storage where sector granularity flexibility is prioritized over deterministic erase timing.	Choose S25FL512SDSMFB013 when uniform sector size, AutoBoot, or ASP are required for safety-critical boot paths.

Compared with S25FL512SAGMFI000, this part offers identical functionality with optimized packaging for automated assembly; versus W25Q512JW, it delivers deterministic 256-KB erase, AutoBoot, and ASP - essential for ASIL-B and SIL-2 certified boot architectures.

FAQ

What is the maximum clock frequency supported for DDR read operations?

The S25FL512SDSMFB013 supports Fast Read DDR, Dual Read DDR, and Quad Read DDR at up to 80 MHz clock rate, delivering 20 MBps, 40 MBps, and 80 MBps respectively when VIO = VCC = 3.0–3.6 V. DDR mode requires proper setup via Configuration Register bits and is not enabled by default after power-on.

Does this device require external hardware for ECC correction?

No. The S25FL512SDSMFB013 includes fully integrated hardware ECC that automatically detects and corrects single-bit errors during read operations without CPU intervention or external circuitry. No additional components or software drivers are needed to enable this function.

Can the OTP area be reprogrammed after initial programming?

No. The 1024-byte One-Time-Programmable (OTP) array is permanently programmed using high-voltage pulses and cannot be erased or rewritten. Once written, its contents remain immutable - making it suitable for storing cryptographic keys, device identifiers, or calibration constants requiring permanent integrity.

Is the FAB024 FBGA package compatible with standard reflow profiles?

Yes. The S25FL512SDSMFB013 in FAB024 package (6 × 8 mm, 0.8 mm pitch) is qualified for lead-free reflow per JEDEC J-STD-020D, supporting peak temperatures up to 260°C. Recommended profile includes ramp rate ≤3°C/s, time above 217°C of 60–150 s, and cooling rate ≤6°C/s.
