Philips Debuts 8-bit Microcontroller with 2 Analog-to-Digital Converters

6/14/2004 - As consumers increasingly integrate technology into their everyday lives, manufacturers are forced to adopt more cost-effective solutions into their systems to appeal to this market segment. To meet these demands, Royal Philips Electronics (NYSE: PHG, AEX: PHI) announced a low-priced microcontroller, the LPC935, which features two analog-to-digital (A/D) converters. At a fraction of the cost of competitive offerings, the LPC935 is the flagship chip of nine new microcontrollers in the LPC900 family designed for a variety of consumer devices from coffeemakers and washing machines to intelligent toys. Used in such applications, the LPC935 bridges the man-machine worlds, enabling the ADC and DAC conversions between the analog and digital computing worlds.

With two A/D converters, the LPC935 can simultaneously convert and read data in two channels, providing designers the advantages of real-time data analysis, such as simultaneously reading voltage and current measurements. The LPC935 converts these signals in less than four microseconds. With fewer external components required and a small footprint for compact integration, each of the new LPC900 family microcontrollers – the LPC904, LPC915/6/7, LPC924/5 and LPC933/4/5 – allows customers the flexibility to select A/D conversion or high-speed digital-to-analog (ADC/DAC) output. By offering ADC/DAC functionality, customers will no longer need to use separate ADC or DAC on their printed circuit boards (PCBs) that are already integrated into the LPC900 family. The new microcontrollers also offer customers the ability to define data reading boundaries for when response is necessary, thereby freeing up the CPU to handle other tasks.

“With the LPC900 family, Philips demonstrates its strong position in the home appliance semiconductors market,” said Wu Jie Huang, CEO, Ningbo Xiyu Electronic Developing Co. Ltd. “The LPC935’s unique features allow us to differentiate our products from those of our competition. These microcontrollers offer a very cost-effective solution for our home appliance protection products. Our partnership with Philips has allowed us to improve design efficiency and respond quickly to market demands.”

“Although our existing LPC900 family is successful in the market, we knew that expanding the family with ADC/DAC capabilities would benefit our customers as they continue to demand more functionalities and lower component count,” said Joe Yu, strategic marketing manager, Standard IC and Microcontroller Business Line, Philips Semiconductors. “By including ADC/DAC functionalities into these new microcontrollers, Philips provides its customers with a complete selection from 8-pin and up. Being able to offer these features for less than $2 in a market where the usual price for such components can reach five times as much, makes our solution even more attractive.”

Additional features of the LPC900 family
Armed with byte-erasable flash technology for enhanced flexibility and performance, the LPC900 family is based on a high-performance processor architecture that executes instructions in 167 ns at 12 MHz (600 percent improvement over the traditional 80C51). The LPC900 features a real-time clock (RTC) and three other 16-bit counter/times, resulting in enhanced timing functions. The family also features serial communication channels such as a 400 kHz byte-wide I˛C-bus, enhanced UART and SPI. The flexible power management features also help extend the battery life of handheld applications.

All of the new devices are available now in quantities of 10,000.
