Integrated LCD, Ethernet and CAN to ARM7 Microcontrollers - LPC2478 and LPC2470 - NXP

NXP announced its new LPC2478 microcontroller, featuring 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.

Peripherals supported by the NXP LPC2478 and LPC2470 microcontrollers in addition to the LCD interface include Ethernet, USB host/OTG/device, two CAN channels, four UARTs, three I2C buses, two-input and two-output I2S, SPI, SSP, RTC, ADC/DAC, SD/MMC card interface, external interfaces to SRAM, SDRAM and NOR Flash.

The NXP LPC2478 and LPC2470 microcontrollers will be available in April.
