Product details

Overview

S25FL064LABBHV033 from Infineon is a 64 Mb (8 MB) serial NOR flash memory IC using 65-nm floating gate technology, operating from 2.7 V to 3.6 V, supporting SPI multi-I/O (SIO/DIO/QIO/QPI), DDR read modes, and uniform 4 KB/32 KB/64 KB erase sectors. It enables XIP execution and code shadowing in space-constrained embedded systems such as industrial controllers and automotive infotainment head units.

For engineers reviewing the S25FL064LABBHV033 datasheet, S25FL064LABBHV033 pinout, S25FL064LABBHV033 application, or S25FL064LABBHV033 equivalent, key selection considerations include Quad I/O read throughput up to 54 MBps, 100,000 program-erase cycles, industrial temperature grade (–40°C to +85°C), security region protection, and SOIC-16 package compatibility with legacy S25FL-A/S25FL1-K families.

Technical Context

The S25FL064LABBHV033 implements a serial flash architecture with configurable 24-/32-bit addressing, SFDP-compliant configuration registers, and dual-edge DDR read capability for QIO/QPI commands. Its command set supports suspend/resume during program and erase operations, enabling real-time system responsiveness.

It integrates four 256-byte non-volatile Security Regions outside the main array, with programmable lock-down via Status Register Protect (SRP0/SRP1), WP# pin control, and password-protected access to Regions 2–3 and the Pointer Region - all compliant with JEDEC JESD216B parameter tables.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory size	64 Mb (8 MB) organized as 128 × 64 KB blocks; enables full firmware storage for mid-tier microcontrollers.
Interface	SPI multi-I/O with SIO/DIO/QIO/QPI and DDR support; reduces pin count vs parallel NOR while matching its bandwidth.
Max read rate	54 MBps (Quad I/O at 108 MHz SDR or DDR Quad I/O at 54 MHz); sufficient for real-time XIP of ARM Cortex-M4/M7 code.
Erase granularity	Uniform 4 KB sectors, 32 KB half-blocks, 64 KB blocks; allows fine-grained firmware updates without full chip erase.
Endurance & retention	100,000 program-erase cycles minimum; 20-year data retention at 85°C; validated for long-life industrial deployments.
Supply voltage	2.7 V to 3.6 V single supply; compatible with 3.3 V logic rails and brown-out tolerant power domains.
Temperature grade	Industrial (–40°C to +85°C); qualified for factory automation PLCs and outdoor telecom edge nodes.

Pinout & Package

Package: 16-lead SOIC 300 mil (SO3016), Pb-free, RoHS-compliant.

Pin/Terminal	Circuit Role	Design Meaning
CS#	Chip Select	Active-low enable for SPI command latching; supports multi-device daisy-chaining with independent addressing.
SO / IO1	Serial Output / I/O Line 1	Primary output in SIO mode; bidirectional data lane in DIO/QIO/QPI; supports dual-edge sampling in DDR mode.
WP# / IO2	Write Protect / I/O Line 2	Hardware lock for status/config registers; doubles as quad data line; enables hardware-based sector protection.
IO3 / RESET#	I/O Line 3 / Reset Input	Configurable as fourth data line or hardware reset; resets internal state machine without power cycle.
VCC	Power Supply	2.7–3.6 V core and I/O supply; decoupling required within 10 mm of pin per layout guidelines.
VSS	Ground	Signal and power return; separate analog/digital ground not required due to integrated noise suppression.

Key Features

Feature	Design Value
Quad Peripheral Interface (QPI)	Enables single-cycle 4-bit command/address/data transfers, reducing instruction overhead by ~75% vs standard SPI.
Page programming buffer	256-byte internal latch allows full-page writes in one command; eliminates host-side buffering and improves write efficiency.
Erase suspend/resume	Halts 4 KB/32 KB/64 KB erase mid-operation to service higher-priority reads; resumes without data loss or timing penalty.
Security Regions	Four 256-byte protected zones outside main array; used for secure boot keys, calibration data, or OEM-specific parameters.
SFDP compliance	JESD216B-compliant parameter table enables automatic host configuration without hard-coded timing or command tables.

Applications

Industrial PLC Firmware Storage

Automotive ADAS Boot Memory

Use Scenario: Storing firmware images and configuration tables in programmable logic controllers deployed in factory environments with wide temperature swings and EMI exposure.

IC Role / Device Role / Timing Role: Non-volatile boot memory providing XIP-capable code execution and field-upgradable firmware patches.

Use Value: Uniform 4 KB erase enables incremental firmware updates without disrupting runtime logic; 100K cycle endurance supports >10 years of field reprogramming.

Use Scenario: Holding boot loader and safety-critical sensor fusion algorithms in radar/EPS ECUs requiring AEC-Q100 qualification and secure key storage.

IC Role / Device Role / Timing Role: Secure, high-reliability boot memory with hardware-enforced protection of cryptographic keys in Security Regions.

Use Value: Password-locked Security Regions 2–3 prevent unauthorized access to calibration data; industrial-grade temp range meets AEC-Q100 Grade 3 requirements.

Medical Imaging UI Flash

Smart Grid RTU Code Storage

Use Scenario: Hosting GUI assets, localization strings, and diagnostic firmware in portable ultrasound or patient monitor front-ends with strict power and space constraints.

IC Role / Device Role / Timing Role: Low-pin-count SPI flash supporting burst-wrap reads for rapid UI asset loading and fast boot sequences.

Use Value: Quad I/O read at 54 MBps loads 512 KB UI bundle in <10 ms; SOIC-16 footprint fits compact PCB layouts with minimal routing layers.

Use Scenario: Storing communication protocol stacks and metering firmware in remote terminal units installed in outdoor substations with extended temperature and humidity exposure.

IC Role / Device Role / Timing Role: Long-life, high-retention code storage with deep power-down mode (<2 µA) for battery-backed operation during grid outages.

Use Value: 20-year data retention ensures firmware integrity over full equipment lifecycle; standby QPI current (35 µA) extends backup battery life beyond 5 years.

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
Cypress S25FL164K0XMFI001	64 Mb, 1.8 V core, SOIC-16, no DDR support, max Quad Read = 40 MBps	Lacks DDR and SFDP; requires manual timing setup; lower power but reduced bandwidth	Choose for ultra-low-power battery systems where 40 MBps read speed suffices and 1.8 V supply is mandatory.
Winbond W25Q64JVSIQ	64 Mb, 3.3 V, SOIC-8, no Security Regions, max Quad Read = 40 MBps, no DDR	Smaller 8-pin package; no hardware security zones; simpler command set	Choose for cost-sensitive consumer devices needing basic code storage without security or DDR performance.

Compared with S25FL064LABBHV033, the Cypress alternative trades DDR and SFDP for lower voltage operation, while the Winbond part sacrifices security and bandwidth for footprint and cost - making the Infineon device optimal where secure, high-speed, auto-configurable flash is required.

FAQ

Is S25FL064LABBHV033 pin-compatible with earlier S25FL-A series devices?

Yes, it uses identical SOIC-16 pinout and command set subset compatibility with S25FL-A, S25FL1-K, and S25FL-P families. Signal mapping (CS#, SO/IO1, WP#/IO2, IO3/RESET#) matches exactly, enabling drop-in replacement without PCB redesign - provided host firmware supports QPI and SFDP.

Does this device support execute-in-place (XIP) operation?

Yes, it supports continuous read mode (XIP) via Fast Read, Dual I/O, Quad I/O, and QPI commands. The burst-wrap feature enables seamless address wrapping for looped code execution, and DDR Quad Read delivers sustained 54 MBps bandwidth required for real-time XIP on Cortex-M7 and similar cores.

What security mechanisms protect firmware against unauthorized modification?

It provides layered protection: hardware WP# pin lock, Status Register Protect (SRP0/SRP1) bits, four dedicated 256-byte Security Regions with password-locked access, and Individual Block Lock for volatile sector locking. These features collectively prevent accidental or malicious overwrite of boot code and calibration data.

Can S25FL064LABBHV033 operate in deep power-down mode during system sleep?

Yes, it supports Deep Power Down mode with only 2 µA typical current draw. Entry is via instruction 0xB9; exit requires 100 µs wake-up delay after CS# deassertion. This mode preserves memory contents while minimizing energy use in battery-powered or intermittently active systems.
