High security for smart card MCU family
Philips Semiconductors describes SmartMX as the world's first ultra-low-power cost-optimised high-performance family of smart card controller ICs.
Offering significant savings in cost, area and power consumption, the new NXP microcontrollers can be used in 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", says Geoff Lees, General Manager, Microcontroller Product Line, NXP Semiconductors.

"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 768pixel, 15 gray-scale monochromes and up to 24bit/pixel true-colour TFT panels.
For embedded system designers, the LCD implementation allows code execution on-chip and minimises bus contention with frame data retrieval from external memory.
In addition, the new microcontrollers provide 512Kbyte, fast 128bit wide embedded Flash with built-in error correction, for maximum reliability.
The LPC2478 and LPC2470 require only a single voltage (3.3V) power supply and offer a novel real-time clock (RTC) with 2Kbyte of battery-backed 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 new microcontrollers 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, with development tools being demonstrated at Embedded World 2007 in Nuremberg, Germany (Booth #12-442).
Both devices will be available in 208 TFBGA and LQFP packages.
