Product details
Overview
S25FL128LDPBHV020 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.
For engineers reviewing the S25FL128LDPBHV020 datasheet, S25FL128LDPBHV020 pinout, S25FL128LDPBHV020 application, or S25FL128LDPBHV020 equivalent, key selection criteria include quad SPI timing compliance, 1.8 V VCC tolerance, sector protection granularity, erase suspend/resume capability, and JEDEC JESD216-compliant SFDP register support.
Technical Context
This device implements a standard Serial Peripheral Interface (SPI) with extended quad I/O mode for high-speed data transfer. It uses a 4-byte address space to access the full 128 Mbit density and includes hardware write protection via WP# pin and software-controlled block protection.
The memory array is organized into 256 uniform 64-KB sectors and supports both 4-KB subsector and 64-KB sector erase operations. The device complies with JEDEC JESD216B for Serial Flash Discoverable Parameters, enabling automatic configuration by host boot loaders.

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Cypress S25FL128SAGMFI000 | Same density and 1.8 V supply, but uses 16-pin SOIC package and lacks HOLD# pin | Requires PCB redesign; no hold functionality for transfer pausing | Select only if board layout accommodates larger footprint and hold is unused |
| Winbond W25Q128JVSIM | 1.8 V quad SPI NOR flash with identical 8-pin SOIC, but rated only to +85°C and 10K erase cycles | Not qualified for extended temperature or high-update-frequency use cases | Acceptable for commercial-grade consumer devices where cost is primary driver |
Compared with S25FL128SAGMFI000 and W25Q128JVSIM, the S25FL128LDPBHV020 uniquely combines industrial temperature range, 100K endurance, and HOLD# functionality in an 8-pin SOIC - critical for real-time embedded systems requiring field updates and deterministic boot.

FAQ
Is S25FL128LDPBHV020 compatible with legacy SPI controllers?
Yes. It supports standard SPI mode 0 and mode 3 at up to 80 MHz, and maintains backward compatibility with single I/O commands while offering enhanced performance in dual/quad modes. All command sets align with JEDEC JESD216B for interoperability.
Does this part support hardware reset or power-on initialization?
No. S25FL128LDPBHV020 has no dedicated reset pin. Initialization occurs automatically after power ramp and CS# assertion; internal power-on reset circuitry ensures valid state upon VCC stabilization within 100 µs.
What security features does S25FL128LDPBHV020 provide?
It includes software-controlled sector protection (with OTP lock bits), hardware write protection via WP# pin, and volatile/non-volatile status register locking. No cryptographic acceleration or secure boot engine is integrated - security relies on external MCU enforcement.
Can it be used in daisy-chain SPI configurations?
No. S25FL128LDPBHV020 does not support daisy-chaining. Each device requires its own dedicated CS# line. Multi-device systems must use independent chip selects or external multiplexing logic.
