Microchip’s New Family of Low-power PIC Microcontrollers

06 June 2017

Microchip (http://www.microchip.com/) announced the development of a new family of extreme low-power (XLP) microcontrollers especially designed to drive liquid-crystal displays (LCD). The nine-member family (PIC16(L)F19197) products include features such as:

·Battery LCD drive charge pump to ensure that LCD screens maintain consistent contrast even if the battery voltage drops.

·Twelve-bit Computation-ADC2 to make data acquisition and processing more reliable so that touch button and sliders are easily implemented.

·Low-power saving modes such as IDLE (a power saving mode that puts the CPU core to sleep while other operation continue to work) and DOZE (a mode that enalbles the CPU core to run at a slower speed) to optimize power consumption.

·Active clock tuning of the 32 MHz high-frequency oscillator.

·Analog low-power comparator, Zero Cross Detector and a 5-bit Digital-to-Ananlog (DAC) converter.

·Four 10-bit PWMs.

The family has 28- to 64-bit processors with up to 56 kB of Flash and 4 kB of RAM.

According to Microchip, "The PIC16(L)F19197 family is supported by MPLAB® Code Configurator (MCC), a free software plug-in that provides a graphical interface to configure peripherals and functions specific to your application. MCC is incorporated into our award-winning development environments, the down-loadable MPLAB X IDE and the cloud-based MPLAB Xpress IDE.
