Product details
Overview
S25FL128LDPNFA010 from Infineon is a 128-Mbit serial NOR flash memory with quad SPI interface, 1.8 V supply voltage, and 133 MHz read clock frequency, supporting XIP (execute-in-place) operation in automotive-grade applications.
For engineers reviewing the S25FL128LDPNFA010 datasheet, S25FL128LDPNFA010 pinout, S25FL128LDPNFA010 application, or S25FL128LDPNFA010 equivalent, key selection criteria include automotive temperature range (-40°C to +125°C), sector-erase capability, hardware write protection, and dual/quad I/O command support.
Technical Context
This device implements a standard Serial Peripheral Interface (SPI) with extended quad I/O (QPI) mode for high-speed data transfer. It supports continuous read, fast read quad I/O, and wrap-around burst modes with configurable latency.
The memory array is organized as 256 Kbytes per sector across 64 uniform sectors, with a 256-byte page programming buffer and 100K program/erase cycle endurance rating. Internal ECC and error flag reporting support functional safety requirements.
Key Specifications

| Memory Density | 128 Mbit (16 Mbyte) - sufficient for boot code, firmware, and configuration data storage in ECUs |
| Supply Voltage | 1.7 V to 2.0 V - compatible with low-voltage automotive power domains |
| Read Clock Frequency | 133 MHz in Quad I/O mode - enables >50 MB/s effective throughput for XIP execution |
| Operating Temperature | -40°C to +125°C - qualified per AEC-Q100 Grade 2 for under-hood automotive use |
| Endurance | 100,000 program/erase cycles - supports field firmware updates over vehicle lifetime |
| Data Retention | 20 years at 85°C - ensures long-term reliability in high-temp environments |
Pinout & Package
Supplied in an 8-pin SOIC (300 mil) package with standard SPI pinout: /CS, SI, SO, WP#, HOLD#, CLK, VCC, VSS.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /CS | Chip Select | Active-low enable for SPI command decoding; required for multi-device bus arbitration |
| SI | Serial Input | Input for command/address/data during write and register operations |
| SO | Serial Output | Output for read data and status register contents in standard/quad mode |
| WP# | Write Protect | Hardware lock for top/bottom 4-KB sectors; prevents accidental erase/write |
| HOLD# | Hold Function | Pauses ongoing read transfer without deselecting device; preserves bus state |
| CLK | Serial Clock | Master-generated timing reference; up to 133 MHz in QPI mode |
| VCC | Power Supply | 1.8 V core and I/O supply; decoupling required per automotive EMC standards |
| VSS | Ground | Reference return path; requires low-impedance connection to system ground plane |
Key Features
| Feature | Design Value |
|---|---|
| Quad SPI (QPI) Mode | Enables single-cycle 4-bit data transfers, doubling bandwidth vs standard SPI at same clock rate |
| Hardware Sector Protection | Independent locking of top/bottom 4-KB sectors via WP# and status register bits |
| Internal ECC | On-the-fly single-bit error correction and detection with flag reporting for ASIL-B compliance |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY15B104QN-PSOC | 4-Mbit density, FRAM technology, unlimited endurance, but lower capacity and no QPI mode | Better for frequent logging; unsuitable for boot code due to size limitation | Select only when byte-level write endurance and zero write latency outweigh capacity needs |
| MX25L12833FZNI-10G | Same 128-Mbit density and SOIC-8 package, but industrial temp range (-40°C to +85°C) and no AEC-Q100 qualification | Limited to cabin electronics; not approved for powertrain or ADAS use | Acceptable for cost-sensitive non-safety applications where automotive qualification is not mandated |
Compared with CY15B104QN-PSOC and MX25L12833FZNI-10G, the S25FL128LDPNFA010 uniquely combines AEC-Q100 Grade 2 qualification, 128-Mbit density, and 133 MHz quad SPI performance-making it the only option qualified for safety-critical boot memory in powertrain and ADAS systems.

FAQ
Is S25FL128LDPNFA010 pin-compatible with earlier S25FL1xxL devices?
Yes, it shares the same 8-pin SOIC package and SPI pinout with S25FL064L and S25FL128L variants. However, register map differences exist for QPI enable and sector protection bits-firmware must be updated to match the latest datasheet revision.
Does this device support Dual Transfer Rate (DTR) mode?
No, S25FL128LDPNFA010 does not implement DTR mode. It supports standard SPI, dual I/O, and quad I/O protocols only. DTR capability is reserved for higher-tier Semper™ devices like S25HS512T.
What is the maximum allowable /CS pulse width for reliable command latching?
The minimum /CS low time is 20 ns, and maximum pulse width is not limited-/CS must remain asserted throughout command, address, and data phases. Violating the 20 ns minimum causes command decode failure per datasheet AC timing spec tCS.
Can hardware write protection be disabled after initial configuration?
No. Once the Status Register Block Protection bits (SRBP[1:0]) are set via WRSR command, they become permanently locked until power cycle. Permanent protection requires issuing WRDI before WRSR to clear the write enable latch first.
