Overview

The LPC24xx series is built on a 2-AHB bus architecture. Like the LPC23xx series, the LPC24xx features Ethernet, USB FS, and CAN. The LPC24xx further adds a USB Host/OTG, an external bus, and higher I/O count, making this the most powerful series of ARM7-based MCUs in the marketplace. Our newest LPC247x microcontrollers further integrate an LCD controller supporting high resolution STN and TFT panels with up to 24-bit true color. These microcontrollers support Super-Twisted Nematic (STN) and Thin-Film Transistor (TFT) graphic display panels up to 1024 x 768 pixels, from monochrome up to 24-bit true-color, and with hardware cursor support. This capability is ideal for point-of-sale, industrial, and medical/diagnostic applications. Further, the LCD controller supports Windows CE data formats.
