On-chip LCD controller extends reach of ARM MCU family

NXP Semiconductors has extended its LPC24xx family of MCUs based on the ARM7TDMI-S core by introducing the LPC2478 featuring strong peripherals for point-of-sale, medical and industrial applications.

By adding an LCD controller suitable for STN and TFT graphic display panels up to 1024 x 768 pixels, and featuring hardware cursor support, the LPC2478 can host a powerful user interface in addition to the inherent processing and networking capabilities of the LPC24xx series. The LCD driver operates from monochrome up to 24-bit true colour and also supports Windows CE data formats.

The LPC2478 is founded on rich connectivity, and includes a 10/100 Ethernet Media Access Controller (MAC), a USB fullspeed device/host/OTG controller, four UARTs, two Controller Area Network (CAN) channels, an SPI interface, two Synchronous Serial Ports (SSP), three I2C interfaces, as well as an I2S interface.

These interfaces benefit from extensive memory resources, including 64kbyte local SRAM, 16kbyte SRAM for Ethernet, 16kbyte SRAM for general-purpose DMA and 2kbyte battery-backed SRAM. An External-Memory Controller (EMC) and 4MHz internal oscillator are also included, allowing designers to achieve high integration for portable devices and POS equipment.

Developers can also take advantage of 512kbyte on-chip Flash memory, with performance enhancements including 128-bits memory-interface width and an accelerator architecture that permits sequential instruction-execution from Flash at the maximum 72MHz clock rate.
