Product details

Overview

S25FL256LDPBHN023 from Cypress Semiconductor is a 256 Mbit (32 Mbyte) 3.0 V serial NOR flash memory with SPI Multi-I/O interface, supporting SDR/DDR Quad I/O and QPI modes, 4KB uniform sector erase, 100,000 program-erase cycles, and industrial temperature range (–40°C to +85°C). It serves as non-volatile code storage in microcontroller boot systems requiring XIP execution or firmware update capability.

For engineers reviewing the S25FL256LDPBHN023 datasheet, S25FL256LDPBHN023 pinout, S25FL256LDPBHN023 application, or S25FL256LDPBHN023 equivalent, key selection criteria include quad-read throughput (66 MB/s), security region protection (four 256-byte regions), page programming buffer size (256 bytes), and compatibility with legacy S25FL-P/S families.

Technical Context

This device implements a floating-gate 65 nm process architecture with a dedicated Page Programming Buffer enabling 256-byte atomic writes. Its command set supports both legacy SPI single-I/O and extended Dual/Quad I/O protocols-including DDR-capable Quad Read at 66 MHz-while maintaining footprint compatibility with prior S25FL-P and S25FL-S families.

Erase operations are fully uniform across 4 KB sectors, 32 KB half-blocks, and 64 KB blocks, with suspend/resume capability for both program and erase. Security is enforced via configurable Status/Configuration Register locks, volatile/non-volatile block locking, and power-supply lock-down of Security Regions 2–3 and the Pointer Region.

IO3 / RESET#	Quad I/O 3 / Reset Input	Third/fourth I/O in Quad mode; functions as hardware reset when CR2V[7]=1 and not in Quad mode
VDD	Power Supply	Primary 2.7–3.6 V supply; powers core logic and I/O buffers
VSS	Ground	Signal and power reference plane; must be low-impedance connection

Key Features

Feature	Design Value
Quad Peripheral Interface (QPI)	Enables 4-bit-wide command/address/data transfers, reducing instruction latency vs. standard SPI
Serial Flash Discoverable Parameters (SFDP)	JEDEC JESD216B-compliant parameter table allows automatic host configuration without hard-coded timing
Program/Erase Suspend & Resume	Permits interleaved background operations-e.g., servicing real-time interrupts while erasing a sector
Four Independent Security Regions	Each 256-byte region supports separate lock states (volatile/non-volatile), enabling secure bootloader + customer key partitioning
Legacy Footprint Compatibility	Pins and command subset match S25FL-P/S families-enables drop-in replacement in existing PCB layouts

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
S25FL256SAGMFV000	Same density and package; FL-S family, 90 nm process, no DDR support, lower max read rate (52 MB/s)	Lacks DDR and QPI; suitable only where legacy timing margins or cost sensitivity outweigh bandwidth needs	Select if board layout rework is prohibited and DDR/QPI features are unused
MX25L25645GMI-10G	Micron-compatible pinout; 32 MB density; supports DTR Quad but no SFDP; 64 KB erase only	No 4 KB sector erase; no security regions; requires custom driver for non-standard command set	Choose only for cost-driven consumer designs where security and fine-grained erase are unnecessary

Compared with S25FL256SAGMFV000 and MX25L25645GMI-10G, the S25FL256LDPBHN023 uniquely combines DDR-enabled throughput, SFDP auto-configuration, 4 KB erase granularity, and four hardware-isolated security regions-making it optimal for safety-aware, upgradable embedded systems.

Manufacturer

Cypress Semiconductor, now part of Infineon Technologies, designs high-performance memory and microcontroller solutions for industrial, automotive, and IoT applications.

The FL-L family targets space-constrained embedded systems needing high-speed serial flash with robust security, XIP capability, and seamless migration from earlier Cypress SPI flash generations.

FAQ

Does S25FL256LDPBHN023 support Execute-in-Place (XIP) operation?

Yes. The device supports continuous read mode (XIP) with burst wrap addressing, enabling direct code execution from flash without copying to RAM. This is enabled via Fast Read or Quad Read commands and requires host controller support for sustained address incrementing and latency tolerance.

What is the function of the IO3/RESET# pin in Quad I/O mode?

In Quad I/O mode (CR1V[1] = 1), IO3/RESET# operates as the fourth bidirectional data line (IO3). When CR1V[1] = 0 and CR2V[7] = 1, it functions as an active-low hardware reset input. The internal pull-up allows leaving it unconnected if unused, eliminating need for external biasing.

How does the 4 KB sector erase improve firmware update reliability?

Uniform 4 KB sector erase enables atomic firmware patching: each update fits within one sector, allowing verification before erase and rollback on failure. Combined with program/erase suspend, it permits real-time interrupt handling during background erase-critical for deterministic response in industrial control loops.

Can Security Regions 2 and 3 be permanently locked against modification?

Yes. Using Power Supply Lock-down mode with password entry, Security Regions 2 and 3-and the Pointer Region-can be made permanently non-volatile and unalterable. Once locked, no subsequent command (including WRR or WRAR) can modify their contents or protection state, even after power cycle.
