Infineon Technologies S25FL129P0XBHI213

Overview

S25FL129P0XBHI213 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 (including thirty-two 4 KB sub-sectors) and support for Quad I/O, Dual I/O, and Quad Page Programming. It delivers up to 40 MB/s effective read bandwidth via QUAD I/O FAST_READ at 80 MHz, features 100,000 program/erase cycles per sector, 20-year data retention, and integrated OTP (128-bit secure ID + 490-byte user space). It is used in boot code storage for industrial microcontrollers and firmware image storage in network edge devices.

For engineers reviewing the S25FL129P0XBHI213 datasheet, S25FL129P0XBHI213 pinout, S25FL129P0XBHI213 application, or S25FL129P0XBHI213 equivalent, key selection considerations include SPI interface mode compatibility (standard/Dual/Quad), sub-sector erase granularity (4 KB), OTP programmability, and migration path to S25FL128S for new designs.

Technical Context

The S25FL129P0XBHI213 implements a SPI-compatible serial interface with five extended command sets enabling Dual Output Read (DOR), Quad Output Read (QOR), Dual I/O Read (DIOR), Quad I/O Read (QIOR), and Quad Page Program (QPP). Its architecture supports configurable memory protection via Status Register BP2–BP0 bits and W#/ACC pin control, plus hardware-accelerated programming using external 9 V on W#/ACC.

It integrates a 0.09 µm MirrorBit® process-based array with CFI compliance for host auto-configuration, and provides three package options: 16-pin SOIC (300-mil), 8-contact WSON (6 × 8 mm), and 24-ball BGA (6 × 8 mm, 5×5 or 6×4 pinout). The "0XBHI213" suffix denotes the 16-pin SOIC package, Industrial temperature grade (−40°C to +85°C), and lead-free/halogen-free construction.

The S25FL129P belongs to Cypress's Spansion-branded serial NOR Flash family, designed specifically for industrial, networking, and automotive applications demanding robustness, long data retention, and flexible in-system programming.

FAQ

Is S25FL129P0XBHI213 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 higher speed (133 MHz Quad I/O), improved power efficiency, and updated packaging-but without 4 KB sub-sector erase. Designers must evaluate whether firmware update granularity or raw performance is the higher priority.

What does the "0XBHI213" suffix indicate?

The suffix identifies the specific variant: "0X" = 16-pin SOIC package; "B" = Industrial temperature grade (−40°C to +85°C); "H" = Lead-free and halogen-free; "I213" = Standard tape-and-reel packaging (2,000 pcs/reel) with Infineon/Cypress standard marking and traceability. This matches the SO3 016 package drawing in the datasheet.

Can the OTP area be reprogrammed after locking?

No. Once the OTP region is locked via the appropriate command sequence (e.g., OTP Lock command), it becomes permanently read-only. The 128-bit secure ID portion is typically programmed and locked at the factory; the 490-byte user area may be programmed and locked in-system, but lock is irreversible and verified by Status Register bit OTPLOCK.

Does S25FL129P0XBHI213 support standard SPI mode only, or also Dual/Quad?

It supports all SPI modes: standard single I/O (SI/SO), Dual I/O (SI/SO), Quad I/O (SI/SO/W#/ACC/HOLD#), plus Dual Output Read and Quad Output Read. These are enabled via Configuration Register bits and require proper initialization sequences (e.g., setting CR[1] for Quad Enable). All modes operate within the same 2.7–3.6 V supply range.
