ARM Cortex-M3 MCUs with USB interface from NXP Semiconductor

NXP Semiconductor has rolled out new MCU series coded LPC1340 series, a new ARM Cortex-M3 MCU with full-speed USB 2.0 device connectivity enabled by on-chip USB drivers certified by USB-IF. The LPC1340 is supported by VDE IEC 60335 Class B test libraries to support customers in the Class B certification process.

"Having introduced the first Cortex-M0 based LPC1100 MCU series just weeks ago, we are now adding easy-to-use USB connectivity to our pin-compatible Cortex-M3 series," said Geoff Lees, vice president and general manager, microcontroller product line, NXP Semiconductors. "In addition we've created the industry's first virtually free fully integrated open-source development tools for the ARM Cortex platform."

The USB 2.0 device controller supports all 4-transfer types of control, bulk, interrupt, and isochronous supporting USB-based audio applications. Double buffering is supported on both isochronous and bulk end-points. The on-chip USB drivers support both the Mass Storage Class (MSC) and Human Interface Device (HID) class.

The built-in drivers are incorporated in ROM to save approximately 5-6 K bytes of user code. ROM-based firmware drivers offer the dual advantage of low power operation with secure and safe bootloading via USB or other on-chip serial channels. Both Windows and Linux recognize LPC1340 series as a mass storage device. Flash programming is enabled by a simple drag-and-drop action.

Price: Starts at $1.49 for 10k pieces and the development platform under $30.
