New High Performance ARM7 Microcontroller
NXP introduces integrated LCD support to ARM7 microcontroller family
NXP, has released its new LPC2478 microcontroller - the industry’s only ARM7 Flash-based MCU offering integrated LCD support - as well as a Flashless version, the LPC2470. 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. Offering significant savings in cost, area and power consumption, the new NXP microcontrollers are ideal for a wide range of industrial, consumer, retail and medical systems using LCD panels and requiring network or Internet connectivity.
“LCD panels with small displays are now ubiquitous in our daily lives - from mobile phones and portable media players to car entertainment, GPS and point-of-sale systems. LCD screens are also increasingly common in a wide range of industrial and medical equipment that need to support high-speed communications functions,” said Geoff Lees, general manager, microcontroller product line, NXP Semiconductors. “Our newest microcontrollers, the LPC2478 and LPC2470, offer an innovative, cost-effective, low-power solution for LCD applications and are an important addition to NXP's extensive portfolio of ARM-based MCUs.”
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.
The large array of 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.
