Infineon Technologies S25FL128LDPBHA030

Overview

S25FL128LDPBHA030 from Infineon is a 128-Mbit serial NOR flash memory with quad SPI interface, 3.0 V supply voltage, 100 MHz clock frequency, and 133 MHz DDR read speed, used in boot code storage for industrial microcontrollers.

For engineers reviewing the S25FL128LDPBHA030 datasheet, S25FL128LDPBHA030 pinout, S25FL128LDPBHA030 application, or S25FL128LDPBHA030 equivalent, key selection criteria include sector protection granularity, erase suspend/resume capability, and WRSR-protected status register lock.

Technical Context

This device implements a standard Serial Peripheral Interface (SPI) with extended quad I/O (QPI) mode supporting single/dual/quad I/O read and write operations. It features a 256-byte page programming buffer and supports uniform 4-KB sectors and 64-KB blocks.

Erase operations are hardware-controlled with internal timing; the device supports both sector and bulk erase with typical times of 0.5 s and 35 s respectively. The status register includes write enable latch (WEL), write in progress (WIP), and block protect (BP) bits.

FAQ

What is the maximum clock frequency supported in DDR mode?

The S25FL128LDPBHA030 supports up to 133 MHz in DDR (double data rate) read mode, achieving 266 million transfers per second. This is specified under VCC = 3.0–3.6 V and ambient temperature range –40°C to +105°C, with setup/hold timing validated per JEDEC JESD252A.

Does this device support software reset commands?

No, the S25FL128LDPBHA030 does not support software reset via instruction; it requires assertion of the dedicated RESET# pin for hardware-initiated reset. The RESET# pin must be held low for ≥20 μs to ensure full internal state recovery and register initialization.

How many bytes can be programmed per page write operation?

The device supports 256-byte page programming, meaning up to 256 contiguous bytes may be written in a single PROGRAM command. Programming beyond this limit requires multiple page write commands, and partial page writes are permitted without prior erase.

Is the WP# pin active-high or active-low?

The WP# pin is active-low: when pulled low, it enables hardware write protection for sectors controlled by the status register BP bits. When WP# is high (≥0.7 × VCC), hardware protection is disabled and software-based protection remains configurable via WRSR.
