Overview

The USB2250I-NU-06 is a high-speed USB 2.0 flash media controller designed for industrial-grade applications requiring reliable data transfer between USB and various memory card formats. It features an integrated 8051-based microprocessor, 64KB of flash memory, and 14KB of RAM to manage complex file systems and interface protocols. The device includes on-chip power FETs and a 1.8V regulator to reduce external component count and simplify PCB routing.

Why Choose This Part

This controller minimizes BOM cost by integrating four card power FETs and a core voltage regulator while providing fold-back short circuit protection. Its industrial temperature rating of -40C to 85C and optimized 128-VTQFP pinout ensure stable performance and easier signal integrity management in dense hardware designs.

Applications

Industrial Data Logging
High-reliability interface for logging sensor data to SD or MMC cards in harsh industrial environments.
Embedded Storage Modules
Integrated flash memory bridge for internal storage within ruggedized computer systems.
Secure Card Readers
Used in building access control or identification systems requiring high-speed USB communication with memory cards.
Medical Diagnostic Equipment
Reliable data transfer from portable diagnostic devices to external workstations via USB 2.0.

Getting Started

To begin development, consult the Microchip ProTouch tool for configuration and firmware customization. Hardware designers should reference the recommended 24 MHz crystal circuit and provide a stable 3.3V supply to meet the 135mA peak high-speed current requirement.

Also Consider

USB2514BI MCHPMicrochip Technology - Suitable if you require a USB 2.0 hub controller for multiple downstream ports rather than a dedicated media card bridge.
USB4604I MCHPMicrochip Technology - Provides higher integration with USB 2.0 hub features and HSIC support for mobile or tablet-based industrial designs.
