Product details

Overview

S25FL256LDPNFB010 from Infineon is a 256-Mbit serial NOR flash memory with Quad SPI interface, 1.8 V supply voltage, 133 MHz clock frequency, and uniform 256-byte sector erase capability. It serves as non-volatile program/data storage in microcontroller-based embedded systems requiring fast read access and reliable code execution.

For engineers reviewing the S25FL256LDPNFB010 datasheet, S25FL256LDPNFB010 pinout, S25FL256LDPNFB010 application, or S25FL256LDPNFB010 equivalent, key selection criteria include Quad SPI timing compliance, 1.8 V I/O compatibility, sector protection granularity, and industrial temperature range support (–40°C to +105°C).

Technical Context

This device implements a standard Serial Peripheral Interface (SPI) with extended Quad I/O mode supporting single/dual/quad data line operation. It uses a 4-byte address space to access the full 256 Mbit density and supports both volatile and non-volatile configuration register writes for mode control.

The memory array is organized into 512 uniform sectors of 256 KB each, with hardware write protection via WP# pin and software-controlled block protection bits. Erase suspend/resume and program suspend/resume functions enable concurrent background operations.

Key Specifications

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
S25FL256SDPNFB010	Same density and package but with 3.0 V supply range (2.7–3.6 V); no 1.8 V I/O compatibility	Requires 3.3 V system rail; unsuitable for low-voltage SoC interfaces	Select only if host MCU uses 3.3 V SPI signaling and industrial temp range is not required
MX25L25645GMI-13G	256 Mbit Quad SPI flash with 3.3 V supply and 104 MHz max clock; lacks program suspend/resume	No background operation interruption capability; lower throughput in quad mode	Choose for cost-sensitive 3.3 V designs where suspend functionality is unnecessary

Compared with S25FL256SDPNFB010 and MX25L25645GMI-13G, the S25FL256LDPNFB010 uniquely combines 1.8 V operation, 133 MHz speed, and full suspend/resume support-critical for battery-powered or thermally constrained embedded systems requiring deterministic flash access.

FAQ

Is S25FL256LDPNFB010 compatible with standard SPI controllers?

Yes, it supports legacy SPI modes (single I/O) in addition to Dual and Quad I/O. Standard SPI initialization sequences work, but Quad mode requires configuration register setup and proper I/O pin routing. The device maintains backward compatibility while enabling higher bandwidth when Quad mode is enabled.

What is the endurance and data retention specification?

This device guarantees 100,000 program/erase cycles per sector and 20-year data retention at 85°C. Endurance is validated per JEDEC JESD22-A117, and retention testing follows JESD22-A108 under accelerated thermal stress conditions.

Does it support execute-in-place (XIP) operation?

Yes, the device supports true XIP with continuous read mode and wrap-around addressing. Its 133 MHz clock and low latency (8 ns initial access, 6 ns page access) enable direct code execution from flash without copying to RAM, reducing system memory footprint.

How is hardware write protection implemented?

Hardware write protection is controlled by the WP# pin: when pulled low, it locks all sectors except those explicitly unlocked via the status register. This complements software-based protection bits and provides fail-safe protection against accidental writes during power transients or firmware faults.
