8-bit PIC MCUs Set For Battery-powered LCD Designs


Microchip has unveiled new 8-bit microcontrollers (MCUs) ideal for driving low-power and battery-powered touch-enabled LCD applications.

The PIC16F19197 MCUs integrate a battery-friendly LCD drive charge pump, 12-bit Analog-to-Digital Converter with computation (ADC2), a low-power comparator and active clock tuning of its high-frequency oscillator.

The new MCUs include 28- to 64-pin devices with up to 56 KB Flash and 4 KB RAM. The charge pump ensures that LCD screens maintain consistent contrast even as battery voltage drops.

The ADC2 automates signal acquisition and processing tasks, making robust touch buttons and sliders easy to implement.


The Active Clock Tuning feature provides customers with an extremely stable oscillator across the entire voltage and temperature operating range. This helps the MCUs to accomplish this entirely in hardware rather than relying upon software, says Microchip.

The family also features a Real Time Clock and Calendar (RTCC) with battery backup and high-current I/O pins to directly drive the LCD backlighting.

Additionally, IDLE/DOZE low-power modes and Peripheral Module Disable (PMD) extend battery life.

The MCUS are able to drive up to 360 LCD segments, making the PIC16F19197 family an ideal choice for battery-powered LCD applications.

“This PIC16F19197 family makes the design of low-power LCD applications easy,” said Steve Drehobl, vice president of Microchip’s 8-bit MCU division. “All of these new features can be set up in MPLAB Code Configurator (MCC), significantly reducing development time and shortening time to market.”

The family is supported by the MPLAB Code Configurator (MCC), which is a free plug-in for MPLAB X and MPLAB Xpress Integrated Development Environments, that provides a graphical interface for the configuration of peripherals and functions specific to your application.

Microchip offers the LCD XLP Explorer Development Board (part #DM240314) for evaluation of the PIC16F19197 family of MCUs.

The first members of the family are available for volume production and sampling. The products are offered in a variety of package options. Volume pricing begins at $1.03 each in 10,000 unit quantities.
