Infineon Technologies S25FL129P0XBHI210

Overview

S25FL129P0XBHI210 from Cypress Semiconductor is a 128-Mbit (16 MB), single-supply 2.7–3.6 V serial NOR Flash memory with uniform 64 KB sectors and dual/quad I/O support. It features 104 MHz FAST_READ, 40 MB/s quad I/O effective data rate, 100,000 program/erase cycles per sector, 20-year data retention, and integrated OTP (16-byte secure ID + 490-byte user space). Used in boot code storage for industrial microcontrollers and FPGA configuration.

For engineers reviewing the S25FL129P0XBHI210 datasheet, S25FL129P0XBHI210 pinout, S25FL129P0XBHI210 application, or S25FL129P0XBHI210 equivalent, key selection criteria include SPI interface timing compliance, sector protection granularity (4 KB sub-sectors), W#/ACC-accelerated programming, and BGA/WSON package compatibility with PCB layout constraints.

Technical Context

The S25FL129P0XBHI210 implements a SPI-compatible serial interface with five extended command sets: DOR, QOR, DIOR, QIOR, and QPP - enabling dual- and quad-I/O read/write operations at up to 80 MHz clock rate. It supports both uniform 64 KB sectors (with 32 × 4 KB sub-sectors) and uniform 256 KB sectors via configuration register setting.

Internal architecture includes a 0.09 µm MirrorBit® floating-gate process, CFI-compliant identification, JEDEC-standard two-byte device ID, and hardware-based memory protection using BP2–BP0 bits plus W#/ACC pin control. OTP programming uses dedicated OTPP/OTPR instructions and supports factory or field locking.

FAQ

Is S25FL129P0XBHI210 still recommended for new designs?

No. Cypress explicitly states this part is "not recommended for new and current designs." The factory-recommended migration path is S25FL128S, which offers higher performance, extended endurance, and active lifecycle support. S25FL129P0XBHI210 remains available for legacy design support and obsolescence mitigation only.

What package does S25FL129P0XBHI210 use, and is it pin-compatible with other variants?

S25FL129P0XBHI210 uses a 24-ball BGA package (6 × 8 mm, 6 × 4 pin configuration, FAC024 footprint). It is not pin-compatible with the SO-16 or WSON-8 variants of the same family - each package has distinct pin assignments and thermal/mechanical requirements.

Does this device support execute-in-place (XIP) operation?

Yes. With FAST_READ (104 MHz) and Quad I/O modes (QIOR at 80 MHz), the device delivers sustained read bandwidth sufficient for XIP operation in Cortex-M7 and RISC-V microcontrollers. However, XIP feasibility depends on host controller's SPI peripheral capabilities and timing margin validation.

How is the OTP area secured, and can it be reprogrammed after locking?

The 16-byte secure OTP region can be programmed once and permanently locked using the LOCK_OTP command. Once locked, the region becomes read-only and immune to further writes or erases. The additional 490-byte OTP space supports multiple program/lock cycles per byte, but final lock is irreversible.
