Infineon Technologies S25FL256LAGBHV020

Overview

S25FL256LAGBHV020 from Infineon Technologies is a 256-Mbit serial NOR flash memory with Quad SPI interface, 3.0 V supply voltage, and 133 MHz read clock frequency. It supports XIP (execute-in-place), dual/quad I/O protocols, and features 100K program/erase cycles with 20-year data retention at 85°C.

For engineers reviewing the S25FL256LAGBHV020 datasheet, S25FL256LAGBHV020 pinout, S25FL256LAGBHV020 application, or S25FL256LAGBHV020 equivalent, key selection criteria include Quad SPI timing compliance, sector protection granularity, deep power-down current (10 µA), and industrial temperature range (-40°C to +105°C) support.

Technical Context

This device implements a standard Serial Peripheral Interface (SPI) with extended quad I/O commands compliant with JEDEC JESD216B. It uses stacked-die architecture to achieve 256 Mbit density in a single package and integrates an internal address counter for sequential read operations.

The memory array is organized into 512 uniform 64-KB sectors and supports programmable block protection via status register bits. Erase suspend/resume functionality enables background operation during firmware updates without halting host execution.

FAQ

Is S25FL256LAGBHV020 pin-compatible with earlier S25FL256S variants?

Yes, it shares identical 8-pin SOIC (208-mil) mechanical footprint and pin assignment with S25FL256S devices. However, electrical behavior differs in deep power-down current (10 µA vs. 20 µA) and Quad SPI timing parameters, requiring validation of timing margins in legacy designs.

Does this part support XIP (execute-in-place) operation?

Yes, S25FL256LAGBHV020 supports true XIP via Quad SPI with continuous read mode and wrap-around addressing. It delivers sustained read throughput up to 532 MB/s, enabling direct code execution without copying to RAM-critical for resource-constrained microcontrollers.

What sector protection mechanisms are implemented?

The device provides both software and hardware protection: status register bits (SRWD, BP0–BP3) enable programmable lock-down of uniform 64-KB sectors, while the WP# pin offers physical override to freeze protection settings during power-up or runtime.

Is AEC-Q100 qualification confirmed for this specific variant?

Yes, S25FL256LAGBHV020 is explicitly qualified to AEC-Q100 Grade 2 (-40°C to +105°C) per Infineon's official product brief and packaging label marking "HV020", indicating automotive-grade screening and test coverage.
