The First Microcontroller Based on the ARM® Cortex™-M0 Processor with Integrated USB Class Drivers

Published:2011/11/30 1:02:00 Author:Phyllis From:SeekIC

NXP Semiconductors’ recent introduced LPC11U2x series is the first microcontroller based on the ARM® Cortex™-M0 processor to offer integrated USB class drivers. The LPC11U2x maximizes Flash memory utilization by integrating multiple USB drivers in ROM, saving up to 16KB of code space while providing fully tested and easy-to-use APIs to enable USB integration in a matter of minutes. The NXP LPC11U00 family of microcontrollers is designed for consumer, industrial, handheld and computing applications, and is the ideal choice for engineers looking for low-cost, easy-to-use USB solutions.

NXP also announced an important step to eliminate a significant start-up cost for potential USB product developers as it will sub-license its USB Vendor ID (VID) and offer Product ID (PID) numbers free of charge to MCU customers. With the LPC11U2x, NXP will also offer USB Implementers Forum (USB-IF) certification, giving users the assurance that their designs comply with the USB specification and are interoperable with existing USB solutions.

In addition to the highly successful LPCXpresso platform, NXP has partnered with the mbed project to create a new mbed NXP LPC11U24 microcontroller board. mbed.org, the ARM-supported rapid prototyping tool for microcontrollers, has extended support of its lightweight online compiler and powerful C/C++ microcontroller SDK to the LPC11U24, making it possible to develop USB devices in a few lines of code.

Low-cost Cortex-M0 based microcontrollers will become one of the most attractive ways to implement USB applications, and with the introduction of the LPC11U24 to the mbed platform, developers can prototype these applications in minutes, backed by the resources and support shared in the mbed community.

The extensible on-chip USB drivers include Human Interface Device (HID), Mass Storage Device Class (MSC), and Communication Device Class (CDC).
The NXP LPC11U2x USB microcontroller series builds on and broadens the company’s popular portfolio of ultra-low-power Cortex-M0 microcontrollers.
NXP LPC11U2x microcontrollers with up to 32K Flash are currently sampling and are available from distributors worldwide. Recommended distribution unit pricing in 10,000 piece quantities for the LPC11U23FBD48/301 with 24K Flash, 8K SRAM and 1K EEPROM is at 1.53 dollars. Higher Flash options (32K to 128K) will also be available for sampling in Q1 2012.
