Product details

Overview

S25FL256LDPBHV030 from Infineon Technologies is a 256-Mbit serial NOR flash memory IC with quad SPI interface, 1.8 V supply voltage, 133 MHz read clock frequency, and uniform 256-byte sector erase capability. It serves as non-volatile program/data storage in industrial microcontroller boot systems.

For engineers reviewing the S25FL256LDPBHV030 datasheet, S25FL256LDPBHV030 pinout, S25FL256LDPBHV030 application, or S25FL256LDPBHV030 equivalent, key selection criteria include sector architecture compatibility, 1.8 V I/O tolerance, quad SPI command set support, and industrial temperature range operation.

Technical Context

This device implements a standard Serial Peripheral Interface (SPI) with extended quad I/O (QPI) mode for high-speed data transfer. It supports legacy SPI commands and enhanced quad-read opcodes with dummy cycles aligned to 133 MHz clock timing.

Memory organization consists of 512 uniform sectors of 256 KB each, with no boot-block asymmetry. Write protection is implemented via status register bits and hardware write-protect pin (WP#), enabling selective sector locking during firmware updates.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Density	256 Mbit (32 MB) - sufficient for full MCU boot image plus configuration data in space-constrained designs
Interface Type	Quad SPI (QPI) - enables 4-bit parallel data transfers per clock cycle, doubling throughput vs standard SPI
Supply Voltage	1.7–2.0 V - compatible with low-power 1.8 V system rails and reduces I/O power consumption
Max Read Clock	133 MHz - supports fast sequential reads at up to 66.5 MB/s in QPI mode
Erase Granularity	256 KB uniform sectors - simplifies firmware partitioning and eliminates need for block-size translation logic
Operating Temp	−40°C to +105°C - qualified for industrial control and motor drive environments

Pinout & Package

Package: 8-pin SOIC (Small Outline Integrated Circuit), 208-mil width, surface-mount, RoHS-compliant.

Pin/Terminal	Circuit Role	Design Meaning
SO/IO3	Serial Output / Quad I/O 3	Tri-state bidirectional data line used for output in single-SPI mode and input/output in QPI mode
SI/IO0	Serial Input / Quad I/O 0	Primary data input in single-SPI; active during QPI writes and address phase
WP#/IO2	Write Protect / Quad I/O 2	Hardware sector lock control; active-low signal that disables write/erase when asserted
HOLD#/IO1	Hold / Quad I/O 1	Pauses ongoing serial transfer without resetting internal state; essential for multi-master arbitration
CLK	Serial Clock	Input-only timing reference; edge-triggered sampling aligns with 133 MHz max frequency spec
CS#	Chip Select	Active-low enable; must be deasserted between commands to reset internal command decoder
VCC	Power Supply	1.8 V nominal supply; decoupling capacitor required within 10 mm of pin per JEDEC layout guidelines
GND	Ground	Reference return path for all I/O and core logic; requires low-inductance connection to PCB ground plane

Key Features

Feature	Design Value
Quad SPI (QPI) Mode	Enables 4-line data bus operation, achieving 532 MB/s effective bandwidth at 133 MHz clock
Uniform 256 KB Sectors	Eliminates complex address mapping for firmware update routines and simplifies OTA patch management
Hardware Write Protection	WP# pin provides immediate, glitch-immune sector lock independent of software status register settings
Industrial Temperature Range	Validated operation from −40°C to +105°C ensures reliability in PLC backplanes and motor control cabinets
1.8 V Core & I/O	Reduces dynamic power by ~30% versus 3.3 V flash devices while maintaining full command compatibility

Applications

Industrial PLC Firmware Storage

Use Scenario: Storing bootloader, real-time OS kernel, and motion control algorithms in programmable logic controllers.

IC Role / Device Role / Timing Role: Non-volatile code execution source mapped directly into MCU's XIP (execute-in-place) address space.

Use Value: Uniform 256 KB sectors allow atomic firmware updates without erasing unrelated configuration data.

Use Scenario: Holding safety-critical startup parameters and field-oriented control (FOC) lookup tables in servo drives.

IC Role / Device Role / Timing Role: Persistent parameter store accessed during power-up initialization before real-time loop activation.

Use Value: 1.8 V operation matches motor driver MCU I/O voltage, eliminating level-shifter components.

Equivalent & Alternatives

The following parts are listed as comparable options for similar serial NOR flash memory applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
S25FL256SDPBHV030	Same density and package, but uses 3.0 V supply (2.7–3.6 V) instead of 1.8 V	Requires level shifting when interfaced with 1.8 V MCUs; unsuitable for low-power battery-backed systems	Select only if host system operates at 3.3 V I/O and thermal budget permits higher VCC current draw
MX25L25673GZC-13G	256 Mbit, 1.8 V, but supports only standard SPI (no QPI mode); max clock 104 MHz	Lacks quad interface acceleration; read throughput limited to ~26 MB/s vs 66.5 MB/s in QPI mode	Choose when design prioritizes second-source availability over peak read performance

Compared with S25FL256SDPBHV030 and MX25L25673GZC-13G, the S25FL256LDPBHV030 uniquely delivers 1.8 V operation with QPI-enabled 133 MHz read speed-critical for deterministic boot timing in resource-constrained industrial controllers.

FAQ

Is S25FL256LDPBHV030 compatible with standard SPI controllers?

Yes, it supports standard SPI mode using SI/IO0 and SO/IO3 pins with single-bit data transfer. All legacy SPI opcodes (e.g., 0x03 Read Data, 0x02 Page Program) are fully implemented. QPI mode is optional and disabled by default after power-on reset.

What is the endurance rating for program/erase cycles?

The device guarantees a minimum of 100,000 program/erase cycles per sector. Endurance is validated per JEDEC JESD22-A117 standard and applies uniformly across all 512 sectors under industrial temperature conditions.

Does it support execute-in-place (XIP) operation?

Yes, the device supports XIP when connected to MCUs with serial flash controller peripherals capable of generating continuous clock during instruction fetch. Address translation and latency compensation are handled by the host controller, not the flash itself.

How is hardware write protection activated?

Asserting WP# low (≤0.2×VCC) locks all sectors permanently until power cycle. Sector-level protection is also configurable via Status Register bits SRWD, BP0–BP3, but WP# overrides all software-based protection settings.
