Simplify the design of Low Power LCD Applications
The PIC16F19197 product family is a line of eXtreme Low-Power (XLP) microcontrollers for driving Liquid Crystal Displays (LCD) that features Core Independent Peripherals and Intelligent Analog. This nine-member family includes battery friendly LCD drive charge pump, 12-bit Analog-to-Digital Converter with Computation (ADC2), low-power comparator, and active clock tuning of its high frequency oscillator. These devices are an ideal solution for low-power and battery powered touch enabled LCD applications. The family consists for 28- to 64-pin devices with up to 56 KB of Flash and 4 KB of RAM.
To support battery applications, the product features a charge pump that ensures LCD screens maintain consistent contrast even as battery voltage drops. High current I/O pins also provide the ability to directly drive LCD backlighting. Each of these features is offered along with the ability to drive up to 360 LCD segments.
The 12-bit ADC2 automates signal acquisition and processing tasks making robust touch buttons and sliders easy to implement. Addition analog features include a Low Power Comparator, Zero Cross Detect (ZCD), and a 5-bit Digital-to-Analog converter (DAC).
Low Power Features
Power saving functions such as IDLE and DOZE low-power modes allow applications to optimize device performance and power consumption. IDLE Mode is a power saving mode that puts the CPU core to sleep while the internal peripherals continue to operate from the system clock and DOZE mode enables the CPU core to run at a slower speed compared to the system clock used by the internal peripherals.
