Product details
Overview
S25FL256LAGBHM020 from Infineon is a 256-Mbit serial NOR flash memory with quad SPI interface, 3.0 V supply voltage, 133 MHz clock frequency, and 8-pin SOIC package. It supports XIP (execute-in-place), sector erase, and deep power-down mode for low-power embedded applications including industrial controllers and IoT edge nodes.
For engineers reviewing the S25FL256LAGBHM020 datasheet, S25FL256LAGBHM020 pinout, S25FL256LAGBHM020 application, or S25FL256LAGBHM020 equivalent, key selection criteria include read latency, erase granularity, write endurance, and SPI command compatibility with host microcontrollers.
Technical Context
This device implements a standard Serial Peripheral Interface (SPI) with Quad I/O (QPI) mode enabling 4-bit data transfers per clock cycle. It uses a 64-Mbyte address space mapped across 512 uniform 64-KB sectors and supports dual/quad read commands with configurable dummy cycles.
The memory integrates an internal charge pump for erase/write operations and features hardware write protection via WP# pin and software-controlled block protection. It operates across industrial temperature range (−40°C to +85°C) and meets JEDEC JESD22-A117 reliability standards.

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 |
|---|---|---|---|
| CY15B104QN-PSOC | 4-Mbit density, FRAM technology, no write delay, unlimited endurance | Better suited for high-frequency data logging; insufficient capacity for full firmware storage | Select when frequent byte-level writes dominate over code storage needs |
| MX25L25645GZC-13G | Same 256-Mbit density, 133 MHz max clock, but uses standard SPI (no QPI) and lacks XIP support | Compatible for basic boot loading but not for real-time XIP execution | Choose if host MCU lacks QPI support or XIP is not required |
Compared with CY15B104QN-PSOC and MX25L25645GZC-13G, S25FL256LAGBHM020 uniquely balances high-density code storage, quad-speed read performance, and XIP capability-making it optimal for complex embedded firmware with tight boot-time constraints.

FAQ
What is the maximum clock frequency supported in Quad SPI mode?
The S25FL256LAGBHM020 supports up to 133 MHz in Quad SPI (QPI) mode, delivering up to 532 MB/s effective read throughput. This frequency is validated under 3.0 V ±10% supply and industrial temperature conditions, and requires proper PCB layout with matched trace lengths and controlled impedance for stable operation.
Does this device support execute-in-place (XIP) functionality?
Yes, the S25FL256LAGBHM020 supports true XIP operation via its Quad SPI interface. The memory controller can fetch instructions directly from flash without copying to RAM, reducing boot time and eliminating the need for external SRAM in cost-sensitive designs.
How many program/erase cycles are guaranteed per sector?
Infineon guarantees 100,000 program/erase cycles per sector, verified per JEDEC JESD22-A117 standard. This endurance rating applies to all 512 uniform 64-KB sectors and remains valid across the full industrial temperature range (−40°C to +85°C).
Is hardware write protection available on this part?
Yes, the WP# (Write Protect) pin provides hardware-level sector protection. When asserted low, it locks all sectors regardless of software protection settings. This feature is independent of VCC and remains active during power transitions, offering robust defense against accidental or malicious firmware corruption.
