The LPC2478 and LPC2470 microcontrollers are the industry’s only ARM7™ Flash-based MCU´s offering integrated LCD support . The LPC2470 is the Flashless version of the LPC2478.
The new microcontrollers feature two ARM® high-speed buses (AHB) for the concurrent operation of multiple high-bandwidth peripherals, including LCD, 10/100 Ethernet, USB host/OTG/device, and two CAN channels.
The NXP LPC2478 and LPC2470 microcontrollers can support most static LCD displays – up to 1024 x 768 pixels, 15 gray-scale monochromes and up to 24 bits per pixel true color TFT panels. For embedded system designers, the LCD implementation allows code execution on-chip and minimizes bus contention with frame data retrieval from external memory. In addition, the new microcontrollers provide 512KB, fast 128-bit wide embedded Flash with built-in error correction, for maximum reliability. The LPC2478 and LPC2470 require only single voltage (3.3V) power supply and offer a unique real-time clock (RTC) with 2KB of battery backed-up SRAM, allowing the device to consume only small amounts of current in power-down while quickly waking up with an external interrupt or at user-determined intervals.
