Preocessor Overview

Processor OverviewAs an innovation leader with its highly-integrated and cost-effective products, NXP Semiconductors realizes that increased performance and functionality, along with lower pricing, is a must in every design. Now, embedded designers can take advantage of higher performance, lower power consumption, and a smaller footprint in applications that require flexible USB connectivity — all at a significantly lower price point with NXP's LPC313x microcontrollers, the industry's lowest cost ARM9 microcontrollers with high-speed (480Mbps) USB 2.0 On-The-Go (OTG).

With an extensive and enhanced feature set, the LPC313x ARM9 microcontrollers are ideal for a wide range of applications, including consumer applications such as advanced remote controls, language translators, A/V home devices, mobile and PC accessories, industrial applications such as industrial controls, factory and building automation, POS systems, bar code readers, e-Metering, security systems, Smart Cards with USB flash and power management systems, medical application such as portable diagnostics and pump and flow metering devices, automotive applications such as engine diagnostics, fleet management and in-dash audio, communications application such as I/O communication and network controllers, and instrumentation and testing applications.

The LPC315x series runs at 180MHz and adds a stereo audio CODEC with class AB headphone amplifier, a Power Supply Unit (PSU), a low-power real-time clock, and a Li-ion battery charger.
