Product details
Overview
S25FL256LAGBHN023 from Cypress Semiconductor is a 256 Mbit (32 Mbyte) serial NOR flash memory with SPI, Dual I/O, Quad I/O, QPI, and DDR read support. It operates from 2.7 V to 3.6 V, features uniform 4 KB/32 KB/64 KB erase blocks, 256-byte page programming, and supports XIP and code shadowing in industrial temperature range (–40°C to +85°C). Used in embedded boot storage for microcontrollers and FPGA configuration.
For engineers reviewing the S25FL256LAGBHN023 datasheet, S25FL256LAGBHN023 pinout, S25FL256LAGBHN023 application, or S25FL256LAGBHN023 equivalent, key selection criteria include quad-mode timing compliance, SFDP register support, security region protection granularity, and DDR read throughput at 66 MHz clock.
Technical Context
The device implements a 65 nm floating gate architecture with a 256-byte page programming buffer and supports suspend/resume for both program and erase operations. Its command set includes standard SPI, extended address modes (24-/32-bit), and JEDEC JESD216B-compliant SFDP for runtime configuration discovery.
It delivers up to 66 MB/s read bandwidth via DDR Quad I/O at 66 MHz, and supports four independent 256-byte security regions outside the main array with non-volatile pointer region locking, power supply lock-down, and password-based protection for Security Regions 2 and 3.

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 |
|---|---|---|---|
| S25FL256SAGMFI000 | Same density and pinout; uses older 90 nm MirrorBit® technology; lacks DDR read mode and SFDP v1.5 support | Lower max read bandwidth (40 MB/s vs. 66 MB/s); no program suspend/resume | Select only if legacy design compatibility or cost sensitivity outweighs performance and feature requirements |
| MX25L25645GMI-08G | 256 Mbit Macronix part in same 24-ball BGA; supports QPI and 133 MHz Fast Read but no DDR mode; different security register mapping | No DDR capability; security region implementation differs - requires driver porting | Choose when cross-supplier qualification is mandated and DDR read is not required in target system |
Compared with S25FL256SAGMFI000 and MX25L25645GMI-08G, the S25FL256LAGBHN023 provides superior bandwidth via DDR Quad I/O, standardized SFDP-driven configuration, and finer-grained security region control - making it optimal for new designs prioritizing real-time responsiveness and secure firmware agility.

FAQ
What is the maximum clock frequency supported in DDR Quad I/O mode?
The S25FL256LAGBHN023 supports DDR Quad I/O operation at up to 66 MHz clock frequency, delivering 66 MB/s effective read bandwidth. This mode transfers address and data on both rising and falling edges of SCK, doubling throughput versus SDR at same clock rate. Timing compliance requires strict setup/hold margins per AC specification section 5.5 of the datasheet.
Does this device support hardware write protection independent of software commands?
Yes - the WP# pin (IO2) provides hardware write protection when CR1V[1] = 0 and SR1NV[7] = 1. In this configuration, driving WP# low disables all write, program, and erase commands regardless of status register settings. The internal pull-up allows safe default operation when the pin is left unconnected.
How many security regions does the S25FL256LAGBHN023 provide, and where are they located?
The device provides four dedicated 256-byte security regions located outside the main 32 Mbyte flash array, starting at address 0x00000000. Regions 2 and 3 support non-volatile locking via power supply lock-down, password, or permanent protection. The pointer region enables non-volatile definition of protected sector/block ranges for flexible firmware partitioning.
Can the S25FL256LAGBHN023 be used in place of the S25FL256SAGMFI000 without hardware changes?
Yes - it shares identical 24-ball BGA (FAB024) packaging, pinout, and voltage specifications. However, firmware must be updated to enable DDR mode, configure SFDP parameters, and leverage program/erase suspend functionality. Migration is supported per Cypress Application Note AN98592, but timing and security register behavior differ.
