New microcontroller LPC2478 from NXP company is based on ARM7 core with built in Flash memory and have built in LCD interface. LPC2470 has no Flash memory.

LPC24 series have two high speed buses AHB to ensure independent work of peripherals like LCD, 10/100 Ethernet, USB and two channels of CAN. LPC24xx have reasonable low prices that allow these MCU to be used in industries like various gadgets, home appliances, medical equipment where LCD is required and also connection to the internet.

LCD displays are part of our life starting from cell phones, media players and car navigation systems GPS. LCD takes important part in medical environment. Where visual information may be critical. So LPC2478 and LPC2470 goes in front of non expensive and low requirements for LCD interfacing.

LPC2478 and LPC2470 supports most of statical LCD displays up to 1024×768 pixels monochrome with fifteen gray levels and color 24bit/pixel TFT panels. Designers of embedded systems have to program LCD functions inside the chip what allows to avoid various conflicts that would occur with external interfacing. LPC2478 comes with 512kB fast internal flash memory with built in error correction to ensure maximum reliability of performance.

LPC2478 and LPC2470 only need to be powered from 3.3Valso there is a real time module (RTC) with separate power supply and internal 2kB battery RAM memory.

Microcontrollers come with wide range of peripherals including two CAN, four UART, three I2C, two input and two output I2S interfaces, SPI, SSP, RTC, ADC/DAC, memory car interface for CD/MMC, external interface for SRAM, SDRAM and NOR Flash.

LPC2478 and LPC2470 are cased in 208 pin TFBGA and LQFP packages what makes them powerful and flexible tools.
