Product details
Overview
S25FL256LDPNFM013 from Infineon is a 256-Mbit serial NOR flash memory with quad SPI interface, 133 MHz clock frequency, and 3.0 V supply voltage, supporting XIP operation in automotive-grade applications up to 105 °C junction temperature.
For engineers reviewing the S25FL256LDPNFM013 datasheet, S25FL256LDPNFM013 pinout, S25FL256LDPNFM013 application, or S25FL256LDPNFM013 equivalent, key selection criteria include automotive AEC-Q100 qualification, 1.8/3.0 V dual-voltage support, sector-erase granularity, hardware write protection, and 20-year data retention at 105 °C.
Technical Context
This device implements a standard Serial Peripheral Interface (SPI) with extended quad I/O (QPI) mode for high-speed read throughput. It uses a 64-Mbyte address space organized into 512 uniform 64-KB sectors and supports both volatile and non-volatile configuration registers.
Internal architecture includes a 256-byte page buffer for fast program operations and a dedicated status register with write-in-progress (WIP), write-enable latch (WEL), and block-protection bits. Erase suspend/resume functionality enables concurrent background erase and foreground read.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Interface | Quad SPI (QPI) - enables 532 MB/s peak read bandwidth using 4-bit I/O lines |
| Max Clock Frequency | 133 MHz - supports high-speed XIP execution without external wait states |
| Supply Voltage | 2.7–3.6 V - compatible with 3.3 V rail and tolerant of transient dips during vehicle cranking |
| Data Retention | 20 years at 105 °C - meets long-life requirement for powertrain and chassis control modules |
| Endurance | 100,000 program/erase cycles per sector - supports over-the-air (OTA) firmware updates across vehicle lifetime |
| Operating Temp | −40 °C to +105 °C - qualified per AEC-Q100 Grade 2 for under-hood automotive use |
Pinout & Package
Package: 8-pin SOIC (300 mil, PNFM). Lead-free, RoHS-compliant, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SO / IO1 | Serial Output / Quad I/O Line 1 | Bi-directional data line used in QPI read/write; requires pull-up for SPI mode compatibility |
| SI / IO0 | Serial Input / Quad I/O Line 0 | Input for standard SPI writes; becomes bidirectional in QPI mode for full-duplex transfers |
| WP# / IO2 | Write Protect / Quad I/O Line 2 | Active-low hardware lock for top/bottom 4 KB sectors; doubles as I/O line in QPI |
| HOLD# / IO3 | Hold Input / Quad I/O Line 3 | Pauses ongoing serial transfer without chip deselect; functions as fourth I/O in QPI |
| CS# | Chip Select | Active-low enable controlling device participation in SPI/QPI bus transactions |
| CLK | Serial Clock | Master-generated timing reference; edge-triggered on rising edge for data sampling |
| VCC | Power Supply | 3.0 V nominal supply; decoupling capacitor required within 10 mm of pin |
| VSS | Ground | Reference return path for all I/O and core logic; must be low-impedance connection |
Key Features
| Feature | Design Value |
|---|---|
| Quad SPI (QPI) Mode | Enables 4-bit parallel data transfers, doubling read bandwidth versus standard SPI without increasing clock rate |
| Hardware Write Protection | Independent top/bottom 4 KB sector locking via WP# pin eliminates need for software-based lock management |
| Erase Suspend/Resume | Allows interrupting background sector erase to service time-critical read requests in real-time ECU environments |
| AEC-Q100 Grade 2 | Validated for continuous operation at 105 °C junction temperature, enabling placement near power semiconductors |
| Program/Erase Resume | Permits recovery from power loss during write/erase operations without data corruption or manual intervention |

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 |
|---|---|---|---|
| S25FL256SDPNFM000 | Same density and package but lacks AEC-Q100 qualification; rated for industrial −40 °C to +85 °C only | Not suitable for under-hood automotive deployments requiring 105 °C operation | Select only for cost-sensitive non-automotive industrial designs with lower ambient temperature requirements |
| MX25L25645GMI-13G | 256 Mbit, 133 MHz, but uses standard SPI (not QPI); no AEC-Q100 qualification | Limited to non-safety-critical consumer or industrial systems without automotive reliability mandates | Choose when QPI bandwidth is unnecessary and qualification documentation is not required |
Compared with S25FL256SDPNFM000 and MX25L25645GMI-13G, the S25FL256LDPNFM013 uniquely delivers AEC-Q100 Grade 2 qualification, QPI-enabled high-speed XIP, and 20-year data retention at 105 °C-making it the only option for safety-critical automotive firmware storage.

FAQ
Is S25FL256LDPNFM013 pin-compatible with earlier S25FL256S variants?
No. While both share the same 8-pin SOIC package, S25FL256LDPNFM013 uses a different pin mapping for QPI functionality: IO2 and IO3 replace dedicated WP# and HOLD# signals in legacy SPI-only versions. Hardware redesign is required for migration.
Does this device support execute-in-place (XIP) operation?
Yes. The S25FL256LDPNFM013 supports true XIP mode via quad SPI interface, allowing direct instruction fetch from flash without copying to RAM. This reduces MCU memory footprint and boot latency in automotive ECUs.
What is the minimum programming voltage tolerance during vehicle cranking?
The device operates down to 2.7 V, meeting ISO 7637-2 Pulse 4 (cold crank) requirements. Internal voltage regulation maintains stable core operation even during 2.8 V transients lasting up to 10 ms, preventing firmware corruption.
How does hardware write protection differ from software-based protection?
Hardware write protection uses the dedicated WP# pin to physically disable program/erase commands for top/bottom 4 KB sectors, independent of firmware state. This prevents accidental or malicious overwrite during runtime, unlike software locks vulnerable to stack overflow or reset glitches.
