LPC24xx series device highlight

Key Features: 72MHz, 32-bit ARM7TDMI-S with dual AHB buses External interface for SDRAM, SRAM, and flash 10/100 Ethernet MAC interface with DMA and MII/RMII interface USB 2.0 full-speed OTG/Device/OHCI plus PHY and DMA Available with LCD STN/TFT graphics controller Wide range of peripherals, including CAN, I2S, ADC, PWM, and more

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.

The LPC2468 microcontroller has 512KB of on-chip high-speed flash memory. It is ideal for multi-purpose communication applications. It incorporates a 10/100 Ethernet Media Access Controller (MAC), a USB full speed device/host/OTG controller with 4KB of endpoint RAM, four UARTs, two CAN channels, and a collection of serial communications.

The LPC247x microcontrollers add integrated LCD controllers. 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.
