LPC24xx device highlight
Introduction
 |
|
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.
Products
LPC2468
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.
LPC2470 and LPC2478
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.
