Infineon Technologies S25FL256LDPBHV023

Overview

S25FL256LDPBHV023 from Infineon is a 256-Mbit serial NOR flash memory with quad SPI interface, 3.0–3.6 V supply voltage, 133 MHz clock frequency, and 100,000 program/erase cycles endurance. It operates in industrial temperature range (−40°C to +85°C) and supports XIP (execute-in-place) for microcontroller boot code storage in embedded control systems.

For engineers reviewing the S25FL256LDPBHV023 datasheet, S25FL256LDPBHV023 pinout, S25FL256LDPBHV023 application, or S25FL256LDPBHV023 equivalent, key selection criteria include quad I/O timing compliance, sector protection granularity, deep power-down current (10 µA), reset recovery time (30 µs), and JEDEC-standard SFDP register support.

Technical Context

This device implements a standard Serial Peripheral Interface (SPI) with extended quad I/O (QPI) mode, supporting single/dual/quad read commands per JEDEC JESD216B. It features a 64-byte page programming buffer and uniform 4-KB sector erase architecture.

Internal logic includes hardware write protection via WP# pin and software-controlled block protection (BP0–BP2 bits), plus volatile status register lock bit. The device uses CMOS floating-gate technology with stacked gate structure for data retention of 20 years at 85°C.

FAQ

Does S25FL256LDPBHV023 support octal DDR interface?

No. This device supports only standard SPI, dual I/O, and quad I/O modes per JEDEC JESD216B. It does not implement octal DDR signaling or DTR (double-transfer-rate) timing. Its maximum interface bandwidth is achieved in quad I/O mode at 133 MHz, delivering 532 MB/s effective throughput.

What is the minimum VCC voltage for reliable reset recovery?

The device guarantees full functionality-including reset recovery within 30 µs-down to 2.7 V VCC, though rated operation is specified from 3.0 V. Below 2.7 V, internal voltage regulators may fail to stabilize, risking incomplete command execution or status register corruption.

Can HOLD# and WP# be used simultaneously during active programming?

Yes. HOLD# suspends ongoing transfers without affecting internal state, while WP# independently disables all write/erase operations regardless of HOLD# status. Both signals are sampled synchronously on CS# deactivation, enabling coordinated bus arbitration and protection in multi-master systems.

Is SFDP table version fixed or configurable?

The SFDP table is factory-programmed per JEDEC JESD216B rev B and cannot be modified. It reports mandatory and optional parameter headers including density, timing, and erase block descriptors. Host systems read this static table at power-up to configure SPI timing and command sets automatically.
