A new family of microcontrollers (MCUs) is an analog system on a chip that integrates a full analog signal chain, including an on-chip precision 16-bit ADC and 10 Msamples/s 12-bit ADC, plus a DAC and dual operational amplifiers (op amps), along with eXtreme Low Power (XLP) technology for extended battery life in portable medical and industrial applications.

This  PIC24FJ128GC010 family offers a combination of analog integration and low power consumption, reduces system cost and noise, and improves the signal throughput in applications such as portable medical monitoring devices, (e.g., blood-glucose meters and blood-pressure monitors), as well as in industrial applications such as portable monitoring devices including voltage and current monitors, gas sensors and high-speed sensor arrays, among others. The PIC24FJ128GC010 family includes an integrated LCD display driver that provides the ability to drive up to 472 segments with information-rich user displays that include scrolling alphanumeric banners. Integrated USB supports the uploading of clinical data for medical equipment, and can act as a service/data port for industrial equipment. Capacitive touch sensing is supported with an on-chip mTouch peripheral. The integration of a 16-bit ADC, USB and LCD into a single low-power MCU allows for very small form factor, battery-powered applications. The PIC24FJ128GC010 family represents a significant cost reduction over a multi-chip implementation, enabling lower noise, faster throughput, smaller PCB size and faster time-to-market.

The new Microchip family appears to have brought together a set of features that can be highly integrated, reducing cost, BOM, board area and power consumptions, and is widely applicable in a host of applications that can take advantage of high-precision analog processing, high computational power, low power consumption and mobility.

Designing precision analog circuits is a challenge. The new family integrates most of the analog signal path to eliminate the chance of introducing noise from onboard components and circuits.  Thus designers get consistent analog performance across applications. Microchip also offers a comprehensive starter kit on which customers can build their software, hardware and sensors—drastically improving their development time by eliminating the need to design a board. The PIC24FJ128GC010 family is supported by Microchip’s MPLAB Starter Kit for PIC24F Intelligent.Integrated.Analog. This kit is focused on the family’s integrated analog to preserve signal integrity. It provides 95% of what designers need to develop a handheld analog prototype—all they need to do is add sensors.
