Microchip has launched a new family of microcontrollers (MCUs). The PIC24FJ128GC010 is an analogue system on a chip that integrates a full analogue signal chain and includes Microchip’s first ever on-chip precision 16-bit ADC and 10 Msps 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 combination of analogue integration and low power consumption helps to significantly reduce system cost and noise, and improves the signal throughput in applications which include portable medical monitoring devices such as blood glucose meters and blood pressure monitors; as well as industrial applications and portable monitoring devices, such as voltage and current monitors, gas sensors and high-speed sensor arrays, among others.
The PIC24FJ128GC010 family includes an integrated LCD display driver that offers 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 (DM240015). The kit is focused on the family’s integrated analogue to preserve signal integrity and provides, according to the company, 95% of what designers need to develop a handheld analogue prototypes – all they need to do is add sensors.
The new PIC24FJ128GC010 MCU family is now avilable for sampling and volume production. The PIC24FJ128GC010 (128 KB Flash) and PIC24FJ64GC010 (64 KB Flash) are available in 100-pin TQFP and 121-pin BGA packages. The PIC24FJ128GC006 (128 KB Flash) and PIC24FJ64GC006 (64 KB Flash) are available in 64-pin TQFP and QFN packages.
