8-bit PIC MCUs for Low-Power LCD Applications

Microchip presents eXtreme low-power (XLP) microcontrollers for driving liquid crystal displays

Microchip’s PIC16F19197 family of MCUs are the first 8-bit MCUs optimized for popular low-power and battery-powered touch-enabled LCD applications. This family consists of 28- to 64-pin devices with up to 56 KB Flash, 4 KB RAM, a real-time clock and calendar (RTCC) with battery backup, and high-current I/O pins to directly drive LCD backlighting. 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.

Additionally, the active clock tuning feature provides customers with an extremely stable oscillator across the entire voltage and temperature operating range. Other features included in this product family include 12-bit analog-to-digital Converter with computation (ADC2), a low-power comparator and active clock tuning of its high-frequency oscillator. The PIC16F19197 family can accomplish this entirely in hardware rather than relying upon software. The battery life of your application can be extended by utilizing the IDLE/DOZE low-power modes and peripheral module disable (PMD) built into the device.

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. These hardware peripherals combined with rich software platform makes the design of low-power LCD applications easy.
