Infineon Technologies S25FL128LDPBHV030

Overview

S25FL128LDPBHV030 from Infineon is a 128-Mbit serial NOR flash memory with 3.0 V supply voltage, 133 MHz Quad SPI interface, and uniform 256-byte programmable sectors. It supports XIP (execute-in-place), deep power-down mode (10 µA), and hardware reset protection for automotive boot code storage.

For engineers reviewing the S25FL128LDPBHV030 datasheet, S25FL128LDPBHV030 pinout, S25FL128LDPBHV030 application, or S25FL128LDPBHV030 equivalent, key selection criteria include quad I/O timing compliance, AEC-Q100 Grade 2 qualification, sector lock granularity, and dual-die stack support in 8-pin SOIC package.

Technical Context

This device implements a standard Serial Peripheral Interface (SPI) with extended Quad SPI (QPI) command set compliant with JEDEC JESD216B. It integrates an internal address counter for sequential read and supports both volatile and non-volatile configuration register writes.

The memory array is organized as 256 Kbytes × 64 bits, with erase granularity of 4-Kbyte sectors and 64-Kbyte blocks. It features 100K program/erase cycles endurance and data retention of 20 years at 85°C.

FAQ

Is S25FL128LDPBHV030 pin-compatible with earlier S25FL128S variants?

No. The S25FL128LDPBHV030 uses an 8-pin SOIC package with Quad SPI pin mapping (IO0–IO3), whereas S25FL128S variants use legacy 16-pin SOIC or different pinouts for dual I/O. PCB layout redesign is required for migration.

Does this device support octal SPI or DDR interface modes?

No. The S25FL128LDPBHV030 supports only standard SPI and Quad SPI (QPI) modes per JEDEC JESD216B. It does not implement octal DTR or DDR timing; maximum interface speed remains 133 MHz single-data-rate QPI.

Can the security register be unlocked after one-time programming?

No. Once the security register lock bit is programmed, it cannot be reversed. This irreversible lock prevents runtime modification of configuration bits such as sector protection status and reset protection enable, ensuring boot integrity.

What is the minimum pulse width for CS# deassertion between commands?

The minimum CS# high time between commands is 50 ns, as specified in the AC characteristics table of the Infineon datasheet (document number 002-12979 Rev. *B). Violating this timing may cause command latch failure or undefined device state.
