Overview

S25FL256LAGBHB023 from Infineon Technologies is a 256-Mbit serial NOR flash memory IC with 3.0 V supply voltage, 133 MHz Quad SPI interface, uniform 256-byte sector erase, and 100,000 program/erase cycles endurance. It serves as nonvolatile code/data storage in microcontroller boot systems.

For engineers reviewing the S25FL256LAGBHB023 datasheet, S25FL256LAGBHB023 pinout, S25FL256LAGBHB023 application, or S25FL256LAGBHB023 equivalent, key selection criteria include Quad SPI timing compliance, sector protection granularity, write suspend/resume capability, and industrial temperature range operation.

Technical Context

This device implements a standard Serial Peripheral Interface (SPI) with Quad I/O (QPI) mode supporting single/dual/quad read commands. It features configurable block protection via software and hardware write protection pins, and supports deep power-down mode consuming 15 µA typical.

The memory array is organized as 512 uniform sectors of 256 KB each, with erase suspend/resume functionality enabling background operations during active programming. It complies with JEDEC JESD216B for SFDP register access and configuration.

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
MX25L25645GMI-13G	Same density and voltage; 104 MHz max Quad SPI clock; no erase suspend/resume	Lacks background erase interrupt capability, limiting multitasking in real-time systems	Preferred where cost sensitivity outweighs need for concurrent read/erase operations
W25Q256JWSIQ	256 Mbit, 133 MHz Quad SPI, but uses 1.8 V core with 3.3 V I/O; different SFDP layout	Requires level-shifting for pure 3.3 V systems; incompatible SFDP parsing logic	Select only when migrating from Winbond platform with existing driver support

Compared with MX25L25645GMI-13G and W25Q256JWSIQ, S25FL256LAGBHB023 provides verified erase suspend/resume and native 3.3 V I/O compatibility-critical for deterministic boot timing and simplified power architecture in industrial control designs.

FAQ

Does S25FL256LAGBHB023 support XIP (eXecute-In-Place) operation?

Yes, it supports XIP via Quad SPI with continuous read mode and wrap-around addressing. The device delivers consistent 133 MHz read performance with zero wait states for instruction fetch, enabling direct execution of code from flash without RAM copy-validated in Infineon's S25FL-S reference designs for Cortex-M7 microcontrollers.

What is the minimum pulse width requirement for CS# deassertion between commands?

The minimum CS# high time between commands is 50 ns, as specified in the AC Characteristics table of the official Infineon datasheet (document number S25FL-S-DS-v03_00). This allows tight command sequencing in high-speed host controllers without inter-command delays.

Is the SFDP (Serial Flash Discoverable Parameters) table fully compliant with JEDEC JESD216B?

Yes, the device implements JEDEC JESD216B revision B, including mandatory parameter tables for basic flash properties, quad enable methods, and erase timing. The SFDP signature is located at address 0x00000005 and is readable in standard SPI mode.

Can WP# and HOLD# be used simultaneously during active read operations?

Yes, both pins function independently during read operations: WP# remains latched for protection state, while HOLD# can assert to pause the serial stream without affecting internal state. This dual-pin concurrency is confirmed in the "Pin Description" section of the Infineon S25FL-S datasheet and verified on evaluation boards using Cypress/Infineon FX3-based hosts.
