Product details

Overview

S25FL512SAGMFA010 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, SFDP, and operates across industrial (–40°C to +85°C) and automotive AEC-Q100 Grade 2 (–40°C to +105°C) temperature ranges.

For engineers reviewing the S25FL512SAGMFA010 datasheet, S25FL512SAGMFA010 pinout, S25FL512SAGMFA010 application, or S25FL512SAGMFA010 equivalent, this device delivers high-speed Quad/DDR read modes, OTP security, advanced sector protection, and drop-in compatibility with S25FL-P family footprints in SO16 and FBGA packages.

Technical Context

This FL-S series flash uses Infineon's 65 nm MIRRORBIT™ technology with Eclipse™ architecture, enabling simultaneous read-while-write capability via dual-bank architecture and supporting both SDR and DDR SPI protocols with clock polarity/phase modes 0 and 3. The device implements a 512-byte page programming buffer and automatic ECC generation during write/erase cycles.

It features extended 32-bit addressing, programmable block protection via status register bits, and Advanced Sector Protection (ASP) with password- or boot-code-controlled individual sector locking. The versatile I/O voltage range (1.65 V to 3.6 V) allows interoperability with mixed-voltage host systems while maintaining full 133 MHz Fast Read performance at VIO = VCC ≥ 2.7 V.

Key Specifications

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 microcontrollers without level shifters.

Pinout & Package

Package: 16-pin SOIC (300 mil), Pb-free, RoHS-compliant, industrial temperature grade (–40°C to +85°C).

Pin/Terminal	Circuit Role	Design Meaning
CS#	Chip Select Input	Active-low enable for SPI command decoding; must be asserted before SCK edge to initiate valid transaction.
SCK	Serial Clock Input	Drives all timing for command, address, and data transfers; supports up to 133 MHz SDR and 80 MHz DDR modes.
SI / IO0	Serial Input / I/O0	Primary data input in standard SPI; functions as bidirectional I/O0 in Dual/Quad modes for parallel data transfer.
SO / IO1	Serial Output / I/O1	Primary data output in standard SPI; functions as bidirectional I/O1 in Dual/Quad modes for parallel read throughput.
WP# / IO2	Write Protect Input / I/O2	Hardware lock for status register and sector protection; doubles as I/O2 in Quad mode for 4-bit data bus expansion.
HOLD# / IO3	Hold Input / I/O3	Pauses ongoing SPI transfer without deselecting device; doubles as I/O3 in Quad mode for full 4-bit I/O capability.
VCC	Core Supply	2.7–3.6 V power for internal logic and array operation; decoupling required per datasheet layout guidelines.
VIO	I/O Supply	1.65–3.6 V supply for pin drivers; independent of VCC to support mixed-voltage host interfaces.
VSS	Ground	Common reference for VCC and VIO; requires low-impedance connection to minimize noise coupling during high-speed reads.

Key Features

Feature	Design Value
AutoBoot Function	Executes preconfigured Normal or Quad Read at power-up/reset - eliminates external boot controller and reduces BOM count in headless systems.
Hardware ECC	On-the-fly single-bit error correction with no software overhead - improves data integrity in noisy environments without sacrificing throughput.
Quad-Input Page Programming (QPP)	Enables efficient programming under slow system clocks by accepting 4-bit-wide input - reduces total programming time in low-power MCU applications.
Advanced Sector Protection (ASP)	Password- or boot-code-triggered per-sector lock - prevents unauthorized firmware modification while allowing selective reprogramming of non-critical partitions.
CFI & SFDP Support	Standardized configuration discovery via JEDEC JESD216 - enables automatic driver initialization and runtime parameter negotiation in Linux and RTOS platforms.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
Cypress S25FL512SDSMFV00	Same die, identical electrical specs and pinout; differs only in marking and tape/reel packaging (no functional difference).	No application impact - fully interchangeable in design and qualification.	Select when sourcing from legacy Cypress channel or requiring specific reel orientation.
Winbond W25Q512JWIM	512 Mb Quad SPI flash with 1.8 V I/O support, but lacks DDR mode, AutoBoot, and ASP; ECC is software-managed.	Not suitable for AEC-Q100 Grade 2 or safety-critical boot scenarios requiring hardware ECC and sector-level password lock.	Consider only for cost-sensitive consumer applications where DDR speed and hardware security are nonessential.

Compared with S25FL512SAGMFA010, the Cypress alternative offers identical functionality with packaging variance, while the Winbond part trades DDR performance and hardware security for lower cost and broader I/O voltage flexibility - making it viable only in non-safety, non-automotive contexts.

FAQ

Is S25FL512SAGMFA010 pin-compatible with earlier S25FL-P series devices?

Yes - it maintains identical SO16 and FBGA footprints and signal assignments with S25FL-P family members, including CS#, SCK, IO0–IO3, WP#, HOLD#, RESET#, VCC, VIO, and VSS. No PCB redesign is needed for migration from S25FL256S or S25FL128S, provided voltage and timing margins are verified per Rev. *U datasheet.

Does S25FL512SAGMFA010 support DDR SPI mode in all temperature grades?

DDR SPI operation is specified only at VIO = VCC = 3.0 V to 3.6 V and is validated across industrial (–40°C to +85°C) and automotive AEC-Q100 Grade 2 (–40°C to +105°C) ranges. DDR timing parameters are not characterized below 3.0 V or outside these temperature limits per Section 5.5 of the datasheet.

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

The OTP region is accessed via dedicated JEDEC-standard One-Time-Program commands (0x4B/0x4C) and locked permanently after programming. Once set, OTP bits cannot be erased or rewritten. Access requires prior Write Enable (0x06) and is blocked if Status Register Bit 7 (SRP) is set to hardware-protected mode using WP# assertion.

What is the maximum sustained write throughput for sequential page programming?

With Quad-Input Page Programming (QPP) enabled and optimal host timing, the device achieves up to 1.5 MBps sustained write throughput - corresponding to ~300 μs per 512-byte page. This assumes continuous command issuance without inter-page delays and accounts for internal ECC computation overhead.
