Product details
Overview
S25FL256LDPNFI013 from Infineon is a 256-Mbit serial NOR flash memory with Quad SPI interface, 1.8 V supply voltage, 133 MHz read clock, and uniform 256-byte programmable sectors. It supports XIP mode and is used in boot code storage for industrial microcontrollers.
For engineers reviewing the S25FL256LDPNFI013 datasheet, S25FL256LDPNFI013 pinout, S25FL256LDPNFI013 application, or S25FL256LDPNFI013 equivalent, key selection criteria include sector architecture, Quad SPI timing compliance, write endurance (100K cycles), data retention (20 years), and industrial temperature range (-40°C to +105°C).
Technical Context
This device implements a standard Serial Peripheral Interface (SPI) with extended Quad I/O commands compliant with JEDEC JESD216B. It uses a 4-bit-wide data bus during fast read and program operations, enabling up to 66.5 MB/s effective throughput.
The memory array is organized as 512 pages of 64 KB each, with erase granularity supporting 64 KB block, 4 KB sector, and chip-erase modes. Internal ECC corrects single-bit errors per 512-byte word without host intervention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 256 Mbit (32 MB) - sufficient for full firmware images including bootloader, OS kernel, and application binaries |
| Interface | Quad SPI (x4 I/O) - enables high-speed read access with reduced pin count vs parallel NOR |
| Read Clock | 133 MHz - supports fast execution-in-place (XIP) from flash without local RAM buffering |
| Supply Voltage | 1.7–2.0 V - compatible with low-voltage microcontroller I/O domains and reduces system power |
| Operating Temp | -40°C to +105°C - qualified for industrial control, motor drives, and outdoor embedded systems |
| Endurance | 100,000 program/erase cycles - suitable for field-upgradable firmware with infrequent updates |
| Data Retention | 20 years at +85°C - ensures long-term reliability in unattended equipment deployments |
Pinout & Package
Supplied in an 8-pin SOIC (300 mil) package with standard SPI pinout: VIO/VCC, GND, /RESET, /HOLD, /WP, SI, SO, SCLK.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /RESET | Hardware reset input | Active-low signal that clears internal state and returns device to default configuration |
| /HOLD | Operation suspend control | Holds ongoing read or program operation without interrupting SPI clock sequence |
| /WP | Write protection enable | Hardware lock for top/bottom 4 KB sectors when asserted low |
| SI | Serial input | Input for command, address, and data during write and erase operations |
| SO | Serial output | Output for read data and status register contents |
| SCLK | Serial clock | Master-generated clock synchronizing all SPI transactions |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S25FL256SDPNFI001 | Same density and package but supports octal DTR interface (up to 200 MHz) and has different sector protection scheme | Targeted at high-performance applications requiring faster random reads (e.g., graphics display buffers) | Select only if system controller supports octal DTR and requires >133 MHz bandwidth |
| MX25L25645GMI-13G | 256 Mbit, 3V supply, 133 MHz max clock, no internal ECC, different sector map (4 KB/32 KB/64 KB) | Suitable for cost-sensitive consumer designs where ECC is handled externally | Choose when 3V I/O compatibility is required and ECC can be implemented in host firmware |
Compared with S25FL256SDPNFI001, this part trades octal bandwidth for lower power and simpler controller interface; versus MX25L25645GMI-13G, it adds ECC and tighter industrial temp grading at higher unit cost.

FAQ
What is the maximum clock frequency supported in Quad SPI mode?
The S25FL256LDPNFI013 supports up to 133 MHz in Quad SPI read mode, delivering 66.5 MB/s effective throughput. This frequency is guaranteed across the full industrial temperature range (-40°C to +105°C) and requires proper PCB layout with matched trace lengths and controlled impedance.
Does this device support execute-in-place (XIP) operation?
Yes, the device supports XIP mode via Quad SPI interface, allowing microcontrollers to execute code directly from flash without loading into RAM. XIP is enabled using the 0x6B (Fast Read Quad Output) command and requires host MCU with appropriate instruction prefetch and caching support.
How is write protection implemented on this flash device?
Write protection is implemented through both software and hardware methods: status register bits (SRWD, BP0–BP3) configure sector-level locks, while the /WP pin provides hardware-level protection for top/bottom 4 KB sectors when held low. Both mechanisms must be disabled to permit programming or erasing.
Is internal ECC available, and what error correction capability does it provide?
Yes, the device includes built-in single-bit error correction (SEC) per 512-byte word using Hamming code. ECC operates transparently during read operations and requires no host intervention. It does not support double-bit error detection or correction.
