Overview

The USB2250-NU-06 is a high-speed USB 2.0 flash media controller designed to interface various memory card formats to a host system. It features an integrated 8051-based 8-bit microprocessor running at up to 60MHz and includes an internal regulator for 1.8V core operation.

Why Choose This Part

This controller offers hardware-controlled data flow and a pipelined architecture to optimize throughput. It simplifies design by including an internal power FET and allowing customization of vendor-specific data via an optional external serial EEPROM.

Applications

Multi-Format Card Readers
Designing standalone or integrated USB readers that support multiple simultaneous card insertions.
Embedded Storage Modules
Adding removable flash storage capabilities to industrial PCs or consumer electronics via a USB 2.0 interface.
Firmware-Upgradable USB Devices
Systems requiring Device Firmware Upgrade (DFU) support for field maintenance over the USB bus.
