Eight-bit microcontrollers
PHILIPS Electronics has released the LPC900 family of eight-bit microcontrollers with two analogue-to-digital converters.
The LPC935 can simultaneously convert and read data in two channels. This allows real time data analysis such as simultaneously reading voltage and current measurements. The LPC935 converts these signals in less than 4μs.
The low-cost devices are intended for consumer applications from coffeemakers and washing machines to intelligent toys. They require external components and have a small footprint. They are capable of A/D conversion or high-speed digital-to-analogue (ADC/DAC) output. This removes the need to use separate ADC or DAC on printed circuit boards that are already integrated into the LPC900 family. Users can also define data reading boundaries for when response is necessary, freeing up the CPU to handle other tasks.
The microcontrollers have byte-erasable flash technology for enhanced flexibility and performance. The LPC900 family is based on a processor architecture that executes instructions in 167ns at 12MHz. The LPC900 has a real time clock and three other 16-bit counter/times. The family also features serial communication channels such as a 400kHz byte-wide I2C-bus, enhanced UART and SPI. The flexible power management features also help extend the battery life of handheld applications.
