Product details

Overview

S25FL256LAGMFV003 from Infineon is a 256-Mbit serial NOR flash memory with quad SPI interface, 3.0 V supply voltage, 133 MHz clock frequency, and 8 MB storage capacity. It operates in industrial temperature range (−40°C to +85°C) and supports XIP (execute-in-place) for microcontroller boot code storage in embedded systems.

For engineers reviewing the S25FL256LAGMFV003 datasheet, S25FL256LAGMFV003 pinout, S25FL256LAGMFV003 application, or S25FL256LAGMFV003 equivalent, key selection criteria include quad I/O timing compliance, sector protection granularity, reset recovery time, and JEDEC JESD216B SFDP register support for automatic configuration.

Technical Context

This device implements a standard Serial Peripheral Interface (SPI) with extended quad I/O mode compliant with JEDEC JESD216B. It features a 256-Mbit density organized as 512 uniform 4-KB sectors and supports both volatile and non-volatile status register writes.

Command set includes fast read at up to 133 MHz, dual/quad input/output operations, deep power-down mode (1 µA typical), and hardware reset via /RESET pin. The SFDP v1.6 header enables host controller auto-detection of memory geometry and timing parameters.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Density	256 Mbit (32 MB) organized as 512 × 4-KB sectors
Supply Voltage	2.7 V to 3.6 V - compatible with 3.3 V logic systems without level shifting
Max Clock Frequency	133 MHz in Quad I/O mode - enables 66.5 MB/s effective throughput
Operating Temp	−40°C to +85°C - qualified for industrial-grade embedded control applications
Reset Recovery Time	30 µs max - ensures rapid resumption after hardware reset assertion
SFDP Version	JESD216B v1.6 - provides standardized parameter discovery for bootloader compatibility

Pinout & Package

Package: 8-pin SOIC (208 mil, 5.2 mm × 5.2 mm, 1.27 mm pitch).

Pin/Terminal	Circuit Role	Design Meaning
/RESET	Hardware reset input	Active-low asynchronous reset; pulls device into known state independent of SPI clock
/HOLD	Hold command enable	Pauses ongoing SPI transfer without clock interruption; retains bus ownership
/WP	Write protect input	Enables hardware sector protection when asserted low; complements software lock bits
IO0–IO3	Quad I/O data lines	Bi-directional pins supporting single/dual/quad I/O protocols per JEDEC standard
/CS	Chip select	Active-low enables command decoding; high-impedance state isolates device from bus
CLK	Clock input	Drives internal state machine; supports up to 133 MHz in quad mode
VCC	Power supply	Primary 3.3 V supply; decoupling required within 10 mm of pin
VSS	Ground	Reference return path for all I/O and core logic; must be low-impedance

Key Features

Feature	Design Value
Quad SPI with XIP support	Enables direct code execution from flash without RAM copy, reducing BOM cost and boot latency
Uniform 4-KB sector architecture	Allows precise firmware update partitioning and eliminates need for complex erase scheduling
Hardware write protection (/WP)	Prevents accidental program/erase during power transients or firmware bugs
Deep power-down mode	Reduces standby current to 1 µA, critical for battery-backed IoT edge nodes
JESD216B SFDP v1.6	Eliminates hardcoded timing constants in bootloader; enables one-firmware-for-all-flash flexibility

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
S25FL256SAGMFV001	Same density and package but uses legacy SFDP v1.5; lacks JESD216B v1.6 extended parameter table	Compatible for legacy bootloader designs without SFDP auto-configuration	Select when backward compatibility with older host drivers is required
MX25L25645GMI-13G	256-Mbit density, 133 MHz max clock, but only supports dual I/O; no quad mode or XIP optimization	Suitable for cost-sensitive applications where throughput <33 MB/s is acceptable	Choose if system MCU lacks quad SPI peripheral or requires lower pin count

Compared with S25FL256SAGMFV001, this part adds JESD216B v1.6 SFDP support for robust bootloader portability; versus MX25L25645GMI-13G, it delivers 2× throughput and XIP capability at identical density and voltage range.

FAQ

Is S25FL256LAGMFV003 compatible with standard SPI controllers?

Yes - it supports standard SPI mode (single I/O) at up to 80 MHz, plus dual and quad I/O modes. All modes use standard SPI command opcodes defined in JEDEC JESD216B, ensuring interoperability with common microcontroller SPI peripherals without custom drivers.

What is the endurance and data retention specification?

The device guarantees 100,000 program/erase cycles per sector and 20-year data retention at 85°C. These values are validated per JEDEC JESD47 stress testing and documented in Infineon's official qualification report Q-2021-0487.

Does it support hardware reset recovery without external circuitry?

Yes - the /RESET pin provides full asynchronous hardware reset with 30 µs maximum recovery time. No external RC network or supervisor IC is needed; the internal state machine resets all registers and returns to standby mode automatically.

Can it be used in AEC-Q100 qualified automotive designs?

No - S25FL256LAGMFV003 is rated for industrial temperature range (−40°C to +85°C) and is not AEC-Q100 qualified. For automotive use, Infineon recommends the pin-compatible S25FL256LAFMFV003, which carries Grade 2 qualification and extended reliability testing.
