Microchip has introduced the PIC24FJ128GC010, a family of analogue systems-on-chip which integrate a full analogue signal chain along with eXtreme Low Power (XLP) technology for extended battery life in portable medical and Industrial applications.
The analogue signal chain in the PIC24FJ128GC010 includes a precision 16-bit ADC and a 10Msamples/s, 12-bit ADC, plus a DAC and dual operational amplifiers alongside the familiar 16-bit PIC® MCU core. The PIC24FJ128GC010 parts also offer an integrated LCD display driver which provides the ability to drive up to 472 segments with information-rich user displays supporting scrolling alphanumeric banners.
Integrated USB capability supports the uploading of data in a medical device, and can act as a service and data port in industrial equipment. An on-chip mTouch® peripheral provides for capacitive touch sensing.
This combination of analogue integration, MCU functions and XLP technology for low power consumption results in reduced system cost and noise, and improves the signal throughput in many medical and industrial applications.
In addition, the integration of a 16-bit ADC, USB and LCD into a single low-power MCU allows for the implementation of very small form-factor, battery-powered applications. By using the PIC24FJ128GC010, designers can achieve a valuable cost reduction compared to a multi-chip implementation, while benefitting from lower noise, faster throughput, a smaller PCB footprint and faster time to market.
