PIC MCU integrates 16-bit ADC, 10 Msps ADC, DAC, USB, and LCDThe PIC24FJ128GC010 is a new family of microcontrollers (MCUs) from Microchip. The new family provides an analog system on a chip (SoC) that integrates a full analog signal chain, including Microchip’s first ever on-chip precision 16-bit ADC and 10 Msps 12-bit ADC. That ship also has 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.
The 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 monitor), as well as industrial applications such as portable monitoring devices (e.g., 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 PIC24FJ128GC010 family is supported by Microchip’s Starter Kit for PIC24F Intelligent.Integrated.Analog (part # DM240015), which is being offered for a special introductory price of $89.99 for a limited time. 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.
