Product details
Overview
S25FL256LDPNFN010 from Cypress Semiconductor is a 256 Mbit (32 Mbyte) serial NOR flash memory with SPI Multi-I/O interface, supporting SDR/DDR Quad I/O and QPI modes, 2.7–3.6 V supply, industrial temperature range (–40°C to +85°C), and uniform 4KB/32KB/64KB erase architecture. It enables XIP execution and code shadowing in space-constrained embedded systems.
For engineers reviewing the S25FL256LDPNFN010 datasheet, S25FL256LDPNFN010 pinout, S25FL256LDPNFN010 application, or S25FL256LDPNFN010 equivalent, key selection criteria include quad read throughput (66 MB/s), 100,000 program-erase cycles, SFDP support, security region protection, and WSON-8 package compatibility.
Technical Context
The S25FL256LDPNFN010 implements a 65 nm floating gate process with a 256-byte page programming buffer and supports burst wrap, continuous XIP, and DDR Quad I/O read modes. Its command set includes full SFDP v1.5 compliance for automatic configuration discovery and legacy block protection plus four 256-byte non-volatile security regions outside the main array.
It features dual-mode I/O routing: SI/SO/WP#/IO3 function as standard SPI signals in single/dual mode but reassign to IO0/IO1/IO2/IO3 in quad mode, controlled by Configuration Register-1 QUAD bit (CR1V[1]). Erase suspend/resume and program suspend/resume are supported across all erase granularities.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 256 Mbit (32 Mbyte) - sufficient for boot code, firmware, and configuration data in mid-tier microcontrollers. |
| Interface Modes | SDR SPI, Dual I/O, Quad I/O, QPI, DDR Quad I/O - enables scalable bandwidth from 6.25 MB/s to 66 MB/s without changing PCB layout. |
| Erase Granularity | Uniform 4 KB sector / 32 KB half-block / 64 KB block - allows fine-grained firmware updates without disturbing adjacent code sections. |

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 pinout, but FL-S family: 90 nm process, no DDR support, max 104 MHz Quad Read (52 MB/s), no SFDP v1.5. | Lacks DDR and SFDP - requires static driver configuration and offers lower bandwidth for XIP. | Select only if legacy design reuse mandates FL-S footprint compatibility and DDR/XIP performance is not required. |
| MX25L25645GMI-10G | Micron-compatible pinout, 3.3 V only (2.7–3.6 V), 100,000 cycles, no security regions, no DDR mode, SFDP v1.5 compliant. | No hardware security regions or erase suspend - unsuitable for secure boot or real-time update use cases. | Choose for cost-sensitive consumer applications where security and real-time interruptibility are not design requirements. |
Compared with S25FL256SAGMFV000 and MX25L25645GMI-10G, the S25FL256LDPNFN010 delivers superior real-time flexibility via DDR Quad I/O, SFDP auto-configuration, and hardware-enforced security regions - critical for industrial and automotive firmware integrity.

FAQ
What is the maximum clock frequency supported in DDR Quad I/O mode?
The S25FL256LDPNFN010 supports DDR Quad I/O at up to 66 MHz clock frequency, delivering 66 MB/s effective read throughput. This is achieved by sampling data on both rising and falling edges of the clock with four I/O lines active simultaneously, as specified in the AC characteristics section (Rev. *A, Table 5-5).
Does this device support hardware reset via the RESET# pin?
Yes - the RESET# pin provides hardware reset functionality. When driven low, it forces the device into standby state and clears internal command registers. In Quad or QPI modes, this pin serves as IO3 unless enabled as RESET# via Configuration Register-2 (CR2V[7] = 1), as detailed in Section 2.8 of the datasheet.
How many security regions does the S25FL256LDPNFN010 provide, and what is their size?
The device provides four independent security regions, each 256 bytes in size, located outside the main flash array. These regions support non-volatile locking, password protection, and power supply lock-down - documented in Sections 1.1 and 8.1 of the datasheet as dedicated areas for bootloader keys and calibration data.
Can the S25FL256LDPNFN010 be used for Execute-in-Place (XIP) operation?
Yes - the device supports continuous read mode (XIP) with burst wrap addressing, enabling direct CPU instruction fetch from flash without intermediate RAM buffering. This is confirmed in the Read Features section (page 1) and validated in Performance Summary (page 2) for Fast, Dual, Quad, and DDR Quad read modes.
