Product details
Overview
S25FL128SDPNFI001 from Cypress Semiconductor (now Infineon) is a 128-Mbit serial NOR flash memory with Quad SPI interface, 3V supply voltage, and 105 MHz clock frequency, supporting XIP (execute-in-place) operation in embedded microcontroller boot applications.
For engineers reviewing the S25FL128SDPNFI001 datasheet, S25FL128SDPNFI001 pinout, S25FL128SDPNFI001 application, or S25FL128SDPNFI001 equivalent, key selection criteria include read latency, sector erase time, write endurance, data retention, and Quad SPI command compatibility for firmware storage in industrial controllers and automotive ECUs.
Technical Context
This device implements a 4-wire Quad SPI interface with dual/quad I/O modes, supporting standard, fast, dual-output, dual-input, quad-output, and quad-input read commands. It uses uniform 256-byte programming and 4-KB sector erase granularity.
The memory array is organized as 256 Kbytes × 64 bits, with hardware reset and write protection via WP# and HOLD# pins. It supports deep power-down mode with 10 µA typical current draw and 100 ms wake-up time.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Supply Voltage | 2.7–3.6 V, compatible with 3.3 V system rails and brown-out tolerant |
| Read Latency | 8 ns address access + 6-cycle dummy clocks at 105 MHz, critical for XIP timing closure |
| Erase Time | Typical 120 ms per 4-KB sector, impacts firmware update duration in field deployments |
| Endurance | 100,000 program/erase cycles per sector, meets 10-year industrial logging requirements |

Pinout & Package
Package: 8-pin SOIC (208 mil width), JEDEC MS-012AC compliant, surface-mount compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SO/QIO | Serial Output / Quad I/O | Bi-directional data line for Quad SPI read/write; requires pull-up for standard SPI fallback |
| SI/QIO | Serial Input / Quad I/O | Bi-directional data line; shares physical pin with SO in quad mode, enabling x4 bandwidth |
| WP#/QIO | Write Protect / Quad I/O | Hardware sector lock when low; doubles as QIO line in quad mode, reducing pin count |
| HOLD#/QIO | Hold / Quad I/O | Pauses ongoing transfer without chip deselect; also functions as fourth I/O in quad mode |
| CLK | Clock Input | Driven by host controller; supports up to 105 MHz for high-speed read bursts |
| CS# | Chip Select | Active-low enable; must be asserted before command and held during transaction |
| VCC | Power Supply | 3.3 V nominal; decoupling capacitor required within 10 mm of pin per layout guidelines |
| GND | Ground | Reference for all I/O and internal logic; separate analog/digital ground not required |
Key Features
| Feature | Design Value |

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 |
|---|---|---|---|
| MX25L12833FZNI-10G | 1.8 V core supply, 133 MHz max clock, no deep power-down mode | Requires level-shifting in 3.3 V systems; higher speed but less power-efficient in always-on nodes | Select for battery-powered IoT gateways needing faster read but accepting voltage translation complexity |
| W25Q128JVSIM | Dual/quad SPI only (no standard SPI fallback), 3.3 V, 133 MHz, 100K endurance | Lacks hardware WP#/HOLD# pin multiplexing; requires additional GPIOs for protection signaling | Prefer for cost-sensitive consumer routers where pin count is not constrained and legacy SPI compatibility is unnecessary |
Compared with MX25L12833FZNI-10G and W25Q128JVSIM, S25FL128SDPNFI001 uniquely balances 3.3 V simplicity, Quad SPI performance, hardware write protection integration, and automotive-grade reliability-making it optimal for industrial and automotive boot memory where robustness and pin efficiency are prioritized over peak clock speed.

FAQ
What is the maximum clock frequency supported in Quad SPI mode?
The S25FL128SDPNFI001 supports up to 105 MHz in Quad SPI read mode, delivering 420 Mbps effective throughput. This frequency is validated across the full industrial temperature range (-40°C to +85°C) with standard 3.3 V supply and proper PCB layout per Infineon's AN98567 layout guidelines.
Does this part support execute-in-place (XIP) operation without external buffering?
Yes, the device supports true XIP operation via its Quad SPI interface, allowing direct instruction fetch by compatible MCUs such as NXP i.MX RT1060 or Infineon AURIX TC3xx. No external cache or buffer is required, provided the host controller implements proper address remapping and latency compensation.
How is hardware write protection implemented on this flash device?
Hardware write protection is implemented through dedicated WP# and HOLD# pins that double as Quad I/O lines. When WP# is pulled low, it locks all sectors or selected sectors based on status register configuration. The protection remains active even after power cycling, ensuring boot code immunity to accidental writes.
Is the S25FL128SDPNFI001 qualified for automotive applications?
Yes, this part carries AEC-Q100 Grade 2 qualification (−40°C to +105°C ambient), with full PPAP documentation available. It is used in production automotive ECUs for boot memory, meeting stringent requirements for data retention, endurance, and thermal cycling reliability per ISO/TS 16949.
