Product details
Overview
S25FL129P0XBHIY10 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 bandwidth via Quad I/O FAST_READ, features 100,000 program/erase cycles per sector, 20-year data retention, and integrated OTP (128-bit secure ID + 490-byte user space). Used in boot code storage for industrial microcontrollers and FPGA configuration.
For engineers reviewing the S25FL129P0XBHIY10 datasheet, S25FL129P0XBHIY10 pinout, S25FL129P0XBHIY10 application, or S25FL129P0XBHIY10 equivalent, key selection criteria include SPI interface timing compliance (up to 104 MHz FAST_READ), sub-sector erase capability (4 KB), W#/ACC-accelerated programming, and BGA/WSON/SO package compatibility with legacy Spansion/Cypress designs.
Technical Context
The S25FL129P0XBHIY10 implements a SPI-compatible serial interface with five extended command sets: Dual Output Read (DOR), Quad Output Read (QOR), Dual I/O Read (DIOR), Quad I/O Read (QIOR), and Quad Page Program (QPP). It supports both uniform 64 KB sectors (with 32 × 4 KB sub-sectors) and uniform 256 KB sectors, enabling flexible firmware partitioning.
Internally, it uses Cypress's 0.09 µm MirrorBit® process and integrates CFI-compliant identification, status/configuration registers, and hardware-based memory protection via BP2–BP0 bits and W#/ACC pin control. The device requires no external high-voltage supply - accelerated programming is enabled by applying 9 V to W#/ACC.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 128 Mbit (16 MB) - sufficient for full MCU boot images and FPGA bitstreams in space-constrained embedded systems. |
| Supply Voltage Range | 2.7 V to 3.6 V - single-supply operation compatible with 3.3 V system rails without level-shifting. |
| Read Speed (Quad I/O) | 80 MHz clock / 40 MB/s effective - enables fast code execution directly from flash (XIP) in real-time applications. |
| Page Program Time | 1.5 ms typical (256-byte page) - defines minimum write latency for firmware updates and parameter logging. |
| Erase Granularity | 4 KB sub-sector, 64 KB sector, 256 KB sector, bulk - allows precise field-upgrade of bootloader sections without erasing entire image. |
| Data Retention | 20 years typical - meets long-life requirements for industrial controllers and medical devices with infrequent reprogramming. |
| Cycling Endurance | 100,000 cycles per sector - supports robust over-the-air (OTA) update mechanisms in connected edge devices. |
| OTP Capacity | 128-bit secure ID + 490-byte user area - enables device authentication and calibration data storage without external EEPROM. |
Pinout & Package
Package: 8-contact WSON (6 × 8 mm), RoHS-compliant, with exposed thermal pad (not electrically connected; may be tied to GND if potential difference is 0 mV).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS# | Chip Select | Active-low enable for SPI communication; required falling edge after power-up before command acceptance. |
| SCK | Serial Clock | Drives all timing: latches input on rising edge, outputs data on falling edge; supports up to 104 MHz. |
| SI/IO0 | Serial Input / I/O0 | Primary data input in standard mode; becomes bidirectional I/O0 in Dual/Quad I/O modes. |
| SO/IO1 | Serial Output / I/O1 | Primary data output in standard mode; becomes bidirectional I/O1 in Dual/Quad I/O modes. |
| W#/ACC/IO2 | Write Protect / Acceleration / I/O2 | Hardware write protection when low; enables accelerated programming at 9 V; serves as I/O2 in Quad modes. |
| HOLD#/IO3 | Hold / I/O3 | Pauses ongoing SPI transfer without deselecting chip; functions as I/O3 in Quad I/O and QPP modes. |
| VCC | Power Supply | Single 2.7–3.6 V supply powers all read/write/erase operations; internal charge pumps generate programming voltages. |
| GND | Ground | Reference for all signals and internal regulation; must be low-impedance connection for stable erase/write margins. |
Key Features
| Feature | Design Value |
|---|---|
| Dual/Quad I/O High-Performance Read | Enables 2×/4× throughput vs standard SPI - critical for XIP-capable MCUs requiring low-latency instruction fetch. |
| Sub-Sector Erase (4 KB) | Allows selective firmware patching without disturbing adjacent boot or config data - reduces OTA update risk and time. |
| W#/ACC Pin Accelerated Programming | Reduces page program time by ~40% when 9 V applied - improves production programming throughput and field update speed. |
| CFI Compliance | Enables automatic flash detection and driver configuration in Linux/Bare-metal bootloaders - eliminates hard-coded timing assumptions. |
| One-Time Programmable Area | Provides tamper-resistant storage for cryptographic keys or device-specific calibration - avoids external secure elements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S25FL128SAGMFI10 | Successor device: same density, 1.8 V/3.0 V dual-voltage support, enhanced 133 MHz Quad I/O, improved ECC, and updated CFI table. | Supports mixed-voltage systems and higher-speed XIP; lacks W#/ACC acceleration but adds built-in error correction. | Select for new designs requiring longer product lifecycle, automotive qualification, or tighter bit-error tolerance. |
| MX25L12833FZNI-10G | 128 Mbit Macronix device: 104 MHz max clock, no W#/ACC pin, no sub-sector erase (only 4 KB sector erase), 100K cycles, 20-year retention. | Compatible pinout in SO8/WSON; lacks Quad Page Program and accelerated programming - slower field updates. | Select where cost sensitivity outweighs programming speed; verify hold-time compliance for existing S25FL129P layouts. |
Compared with S25FL129P0XBHIY10, the S25FL128S offers higher performance and broader voltage support but removes W#/ACC acceleration, while the MX25L12833F provides drop-in layout compatibility at lower cost but sacrifices sub-sector flexibility and programming speed.

FAQ
Is S25FL129P0XBHIY10 still recommended for new designs?
No. Cypress explicitly states this part is not recommended for new or current designs. The factory-recommended migration path is S25FL128S, which offers dual-voltage support, higher Quad I/O speed (133 MHz), and enhanced reliability features. S25FL129P0XBHIY10 remains viable only for sustaining legacy production with documented qualification.
What package does S25FL129P0XBHIY10 use, and is the thermal pad electrically active?
S25FL129P0XBHIY10 uses the 8-contact WSON package (6 × 8 mm, part code "Y"). Its exposed central pad is not electrically connected to any internal circuitry. It may be soldered to a GND copper pour only if PCB routing ensures zero voltage difference between the pad and the GND pin - otherwise, it must remain floating.
Does S25FL129P0XBHIY10 support Quad SPI mode without external high voltage?
Yes. Standard Quad I/O read (QIOR) and Quad Page Program (QPP) operate at normal VCC (2.7–3.6 V); no external high voltage is needed for basic Quad functionality. The 9 V applied to W#/ACC is optional and used exclusively to activate accelerated programming - it does not affect Quad I/O timing or signal integrity.
How is memory protection implemented on S25FL129P0XBHIY10?
Protection is implemented via three Status Register bits (BP2–BP0) that configure block lock/unlock states for top/bottom sectors, combined with hardware control of the W#/ACC pin. When W#/ACC is low, protected sectors cannot be programmed or erased - even if software issues a valid command. This provides hardware-enforced security independent of firmware state.
