Infineon Technologies S25FL256LDPNFB013

Overview

S25FL256LDPNFB013 from Infineon Technologies is a 256-Mbit serial NOR flash memory with Quad SPI interface, 133 MHz clock frequency, and 3.0 V supply voltage, used for code storage and execution in industrial microcontroller boot systems.

For engineers reviewing the S25FL256LDPNFB013 datasheet, S25FL256LDPNFB013 pinout, S25FL256LDPNFB013 application, or S25FL256LDPNFB013 equivalent, key selection criteria include read latency, sector erase granularity, write protection scheme, and JEDEC-standard command set compliance.

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 64-Mbyte address space organized into 512 uniform 64-KB sectors and supports both volatile and non-volatile status register configuration.

The memory employs stacked-die technology to achieve 256 Mbit density in a single 8-pin SOIC package. Erase suspend/resume, deep power-down mode (10 µA), and hardware write protection via WP# pin are implemented at silicon level.

FAQ

What is the minimum VCC voltage for reliable operation of S25FL256LDPNFB013?

The device operates reliably from 2.7 V to 3.6 V. Below 2.7 V, command execution may fail and status register reads become invalid. System designs must ensure brown-out detection engages before VCC drops below 2.7 V to prevent corruption during power-down sequences.

Does S25FL256LDPNFB013 support execute-in-place (XIP) mode?

Yes, it supports XIP mode via Quad SPI with wrap-around burst addressing. The device delivers consistent 133 MHz clock-aligned read latency and maintains valid instruction alignment across sector boundaries, enabling direct CPU fetch without local RAM buffering.

How many program/erase cycles does this flash guarantee?

Infineon specifies 100,000 program/erase cycles per sector. This rating applies across the full industrial temperature range (-40°C to +105°C) and assumes proper command sequencing and voltage compliance per datasheet timing diagrams.

Is hardware write protection enabled by default on power-up?

No. Hardware write protection is disabled by default; the WP# pin must be actively driven low to engage protection. The status register's block protection bits remain unprogrammed after power-on reset, allowing unrestricted writes until explicitly configured.
