Product details
Overview
S25FL128LDPBHI023 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. It supports XIP (execute-in-place), dual/quad I/O protocols, and offers 100K program/erase cycles with 20-year data retention. Used in industrial PLC firmware storage and embedded boot code applications.
For engineers reviewing the S25FL128LDPBHI023 datasheet, S25FL128LDPBHI023 pinout, S25FL128LDPBHI023 application, or S25FL128LDPBHI023 equivalent, key selection criteria include quad SPI timing compliance, 1.8 V VCC tolerance, sector protection granularity, and JEDEC-standard command set support for legacy bootloader compatibility.
Technical Context
This device implements a standard Serial Peripheral Interface (SPI) with extended quad I/O mode using IO0–IO3 as bidirectional data lines. It uses a 4-byte address space with uniform 4-KB sectors and supports both volatile and non-volatile status register configuration.
Command execution follows JEDEC JESD216B specification for SFDP (Serial Flash Discoverable Parameters), enabling automatic configuration by host boot ROM. Erase operations include chip, block (64 KB), and sector (4 KB) levels with hardware write protection via WP# pin and status register bits.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Interface | Quad SPI - enables 532 MB/s peak throughput with 133 MHz clock and 4-bit data bus |
| Supply Voltage | 1.7–1.95 V - matches low-power 1.8 V system rails without level-shifting circuitry |
| Read Clock Frequency | 133 MHz - supports high-speed XIP execution with sub-100 ns random access latency |
| Endurance | 100,000 program/erase cycles - ensures reliable field updates over 10+ years of operation |

Pinout & Package
16-pin Small Outline Integrated Circuit (SOIC) package, 300-mil body width, gull-wing leads, RoHS-compliant matte tin finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (VIO) | I/O Supply | Separate 1.8 V rail for interface logic-decoupled from core VCC to suppress noise coupling into SPI signaling |
| Pin 2 (WP#) | Write Protect | Active-low hardware lock for top/bottom 4-KB sectors-enables secure firmware update partitioning |
| Pin 3 (HOLD#) | Hold Control | Pauses ongoing SPI transaction without clock stop-preserves state during host interrupt servicing |
| Pin 4 (IO0) | Quad I/O Line | Bidirectional data line used for command/address input and data output in quad mode |
| Pin 5 (IO1) | Quad I/O Line | Bidirectional data line supporting dual/quad read/write-enables 4-bit parallel data transfer |
| Pin 6 (IO2) | Quad I/O Line | Used for address/data in quad mode; also serves as A0 in single I/O read commands |
| Pin 7 (IO3) | Quad I/O Line | Enables full quad I/O protocol; required for 133 MHz fast-read and QPI command execution |
| Pin 8 (GND) | Ground | Signal reference for all I/O and core logic-separate GND pin reduces ground bounce during high-speed switching |
| Pin 9 (VCC) | Core Supply | 1.8 V core power-powers internal charge pump and memory array; requires local 1 µF ceramic decoupling |
| Pin 10 (SCLK) | Clock Input | Master-generated SPI clock up to 133 MHz-synchronous edge-triggered for deterministic timing margins |
| Pin 11 (CS#) | Chip Select | Active-low enable signal-assertion initiates command decoding; deassertion terminates transaction cleanly |
| Pin 12 (NC) | No Connect | Internally unused-must be left floating or tied to GND per layout guidelines |
| Pin 13 (NC) | No Connect | Internally unused-no external connection required; avoids routing congestion on dense PCBs |
| Pin 14 (NC) | No Connect | Internally unused-ensures mechanical symmetry in SOIC package; no electrical function |
| Pin 15 (NC) | No Connect | Internally unused-reserved for future feature extension; not bonded in current silicon revision |
| Pin 16 (VSS) | Ground | Dedicated ground return for VCC-minimizes power supply impedance and improves EMI performance |
Key Features
| Feature | Design Value |
|---|---|
| Quad SPI with QPI Mode | Enables 4-bit parallel data transfers at 133 MHz, doubling bandwidth over standard SPI and eliminating need for external multiplexers |
| Hardware Sector Protection | Independent locking of top/bottom 4-KB sectors via WP# pin and status register-prevents accidental overwrite of bootloader region |
| JEDEC JESD216B SFDP Support | Allows host processor to auto-detect memory geometry, timing parameters, and command set-reduces firmware porting effort across flash vendors |
| 100K Endurance / 20-Year Retention | Validated under accelerated life testing at 85°C-supports remote firmware updates in industrial gateways without field replacement |
| 1.8 V Single-Supply Operation | Eliminates need for dual-voltage regulators; simplifies power design and reduces BOM count in battery-backed or energy-harvesting systems |

The following parts are listed as comparable options for similar serial NOR flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Cypress S25FL128SAGBHI200 | Same density and package, but uses legacy 3-byte addressing and lacks SFDP support | Requires manual register configuration; incompatible with hosts relying on auto-discovery | Select when migrating legacy designs with fixed command sets and no SFDP dependency |
| Winbond W25Q128JVSIM | 1.8 V operation with quad SPI, but only 10K endurance and 10-year retention at 85°C | Suitable for consumer devices with shorter lifecycle; insufficient for industrial field updates | Select for cost-sensitive applications where firmware update frequency is ≤1/year and thermal derating is acceptable |

FAQ
Is S25FL128LDPBHI023 compatible with standard SPI controllers?
Yes-it supports standard SPI mode (single I/O) at up to 80 MHz, plus dual and quad I/O modes. Command set complies with JEDEC JESD216B, ensuring interoperability with common boot ROMs and flash programmers. No proprietary initialization sequence is required.
What is the minimum erase block size supported?
The smallest erasable unit is a 4-KB sector. The device contains 4,096 uniform sectors, each independently lockable via hardware (WP#) or software (status register). Chip and 64-KB block erase are also supported for bulk operations.
Does this part support execute-in-place (XIP) operation?
Yes-XIP is fully supported in quad I/O mode. The device delivers consistent 133 MHz read throughput with zero wait states when interfaced to compatible microcontrollers, enabling direct code execution from flash without RAM loading.
How is data integrity protected during power loss?
Internal power-loss detection circuitry halts write/erase operations when VCC drops below 1.5 V, preventing partial page writes. Status register bits indicate suspend/resume readiness, and all commands include CRC validation to reject corrupted instructions.
