Product details
Overview
S25FL129P0XBHIY13 from Cypress Semiconductor is a 128-Mbit (16 MB), 3.0 V serial NOR Flash memory with uniform 64 KB sectors and dual/quad I/O support, operating across 2.7–3.6 V. It delivers up to 40 MB/s effective read throughput via Quad I/O FAST_READ, features 100,000 program/erase cycles per sector, 20-year data retention, and includes 128-bit factory-programmable OTP for secure device identification.
For engineers reviewing the S25FL129P0XBHIY13 datasheet, S25FL129P0XBHIY13 pinout, S25FL129P0XBHIY13 application, or S25FL129P0XBHIY13 equivalent, key selection criteria include SPI interface timing compliance (104 MHz max FAST_READ), sub-sector erase capability (4 KB), W#/ACC-accelerated programming, and BGA/WSON/SO package compatibility in industrial embedded boot code storage.
Technical Context
The S25FL129P0XBHIY13 implements a quad-SPI-compatible serial interface with five extended instructions: DOR, QOR, DIOR, QIOR, and QPP - enabling simultaneous use of SI, SO, W#/ACC, and HOLD# as bidirectional I/O pins. Its architecture supports both uniform 64 KB sectors (with 4 KB sub-sectors) and uniform 256 KB sectors, maintaining backward compatibility with S25FL128P.
Internally, it uses Cypress's 0.09 µm MirrorBit® process and integrates CFI-compliant identification registers, status/configuration registers with BP2–BP0 block protection, and dedicated OTP space (16 bytes + 490 bytes). Accelerated programming requires 9 V applied to W#/ACC, while deep power-down draws only 3 µA typical.

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 |
|---|---|---|---|
| S25FL128SAGMFI000 | Successor device: same density, 1.8/3.0 V dual supply, 133 MHz Quad I/O, no W#/ACC acceleration pin | Supports lower-voltage systems; lacks 9 V acceleration but adds XIP support and enhanced security registers | Select for new designs requiring longer lifecycle support and dual-voltage flexibility |
| MX25L12833FZNI-10G | 128 Mbit, 3 V, 104 MHz max Quad I/O; no OTP area; 50K endurance; different status register layout | Cost-optimized alternative; lacks sub-sector erase and secure OTP - unsuitable for regulated firmware storage | Select only for non-critical consumer applications where OTP and 100K endurance are not required |
Compared with S25FL129P0XBHIY13, the S25FL128S offers higher clock rates and broader voltage support but removes W#/ACC acceleration and reduces OTP flexibility; the MX25L12833F trades endurance and security features for cost, limiting suitability to non-safety-critical use cases.

FAQ
Is S25FL129P0XBHIY13 pin-compatible with S25FL128P?
Yes - S25FL129P0XBHIY13 maintains identical pinout and command set with S25FL128P in uniform 256 KB sector configuration. Both share the same SO, WSON, and BGA package footprints and require no PCB redesign for drop-in replacement in legacy systems.
What is the function of the W#/ACC pin beyond write protection?
The W#/ACC pin serves three roles: (1) write protect when pulled low, (2) acceleration trigger when 9 V is applied (enabling ≤1.5 ms page programming), and (3) I/O2 in Quad I/O and Quad Page Program modes - enabling true 4-line bidirectional data transfer.
Does S25FL129P0XBHIY13 support execute-in-place (XIP)?
No - S25FL129P0XBHIY13 does not support XIP mode. It requires data to be copied into RAM before execution. XIP capability was introduced in the successor S25FL128S, which includes an enhanced instruction set and cache-friendly read modes.
How is the OTP area secured against reprogramming?
The 128-bit OTP region can be permanently locked via the OTP Lock command (B1h), which sets a one-time fuse. Once locked, no further writes or reads are possible - verified by reading status bit OTPLOCK=1. The lock operation is irreversible and hardware-enforced.
