The PIC16F19197 family consists of 28- to 64-pin devices with up to 56 KB of Flash and 4 KB of RAM. A charge pump ensures that LCD displays maintain consistent contrast even when the battery voltage drops. The ADC2 automates signal acquisition and processing, facilitating the implementation of robust touch-sensitive buttons and sliders. Furthermore, Active Clock-Tuning provides customers with an extremely stable oscillator across the entire voltage and temperature range. The PIC16F19197 family is capable of performing all these functions in hardware rather than software.
The family also incorporates a real-time clock and calendar (RTCC) with battery support and high-current I/O pins for direct LCD backlight control. In addition, low-power IDLE/DOZE modes and Peripheral Module Disable (PMD) extend battery life. All these features, along with the ability to control up to 360 LCD segments, make the PIC16F19197 family an ideal choice for battery-powered LCD applications.
The family is supported by MPLAB® Code Configurator (MCC), a free extension for the MPLAB X and MPLAB Xpress integrated development environments that provides a graphical interface for configuring peripherals and application-specific functions. The Microchip LCD XLP Explorer development board (DM240314) is now available for evaluating the PIC16F19197 microcontroller family.
