http://www.nxp.com/#/pip/pip=[pip=LPC2478]|pp=[t=pip,i=LPC2478]

Single-chip 16-bit/32-bit micro; 512 kB flash, Ethernet, CAN, LCD, USB 2.0 device/host/OTG, external memory interface

NXP Semiconductors designed the LPC2478 microcontroller, powered by the ARM7TDMI-S core, to be a highly integrated microcontroller for a wide range of applications that require advanced communications and high quality graphic displays. The LPC2478 microcontroller has 512 kB of on-chip high-speed flash memory. This flash memory includes a special 128-bit wide memory interface and accelerator architecture that enables the CPU to execute sequential instructions from flash memory at the maximum 72 MHz system clock rate.

This feature is available only on the LPC2000 ARM microcontroller family of products. The LPC2478, with real-time debug interfaces that include both JTAG and embedded trace, can execute both 32-bit ARM and 16-bit Thumb instructions.

The LPC2478 microcontroller incorporates an LCD controller, a 10/100 Ethernet Media Access Controller (MAC), a USB full-speed Device/Host/OTG Controller with 4 kB of endpoint RAM, four UARTs, two Controller Area Network (CAN) channels, an SPI interface, two Synchronous Serial Ports (SSP), three I²C interfaces, and an I²S interface. Supporting this collection of serial communications interfaces are the following feature components; an on-chip 4 MHz internal oscillator, 98 kB of total RAM consisting of 64 kB of local SRAM, 16 kB SRAM for Ethernet, 16 kB SRAM for general purpose DMA, 2 kB of battery powered SRAM, and an External Memory Controller (EMC).

These features make this device optimally suited for portable electronics and Point-of-Sale (POS) applications. Complementing the many serial communication controllers, versatile clocking capabilities, and memory features are various 32-bit timers, a 10-bit ADC, 10-bit DAC, two PWM units, and up to 160 fast GPIO lines. The LPC2478 connects 64 of the GPIO pins to the hardware based Vector Interrupt Controller (VIC) allowing the external inputs to generate edge-triggered interrupts.

All of these features make the LPC2478 particularly suitable for industrial control and medical systems.

Philips plugs OLEDs into wall socket

9/8/2010 1:58 PM EDT

SAN JOSE, Calif. – Philips Research has developed an organic light emitting diode module that can be powered directly from a standard wall outlet, accelerating the move to create mainstream OLED products.

Currently, OLEDs require low-voltage direct current (DC) sources. The alternating current (AC) powered white-light module developed by Philips Research can be plugged directly into a wall socket. The prototype suggests future products could eliminate the cost and bulk of for power management conversion circuitry OLEDs need today.

“We have combined proprietary interconnect and packaging technology to create this demonstrator,” said Dirk Hente a researcher at Philips, speaking in a press statement. “We’re already seeing AC-driven LEDs coming onto the market. Our prototype marks a breakthrough step towards a similar evolution in OLEDs,” he said.

OLEDs have some advantages in the quality of light they emit and their compact size compared to other light sources including existing LEDs, Philips said in a statement. The company already sells a line of commercial and industrial OLEDs for lighting.

Philips Research developed its AC-powered module as part of the TOPSA 2012 project funded by the German Federal Ministry of Education and Research. The work was done in collaboration with the Institut für Hochfrequenztechnik in Braunschweig, Germany.
