A new family of low-power microcontrollers (MCUs) for driving Liquid Crystal Displays (LCD) featuring Core Independent Peripherals (CIPs) and intelligent analog is now available from Microchip Technology Inc., a leading provider of microcontroller, mixed-signal, analogand Flash-IP solutions. The nine member PIC16F19197 family includesa 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. They are the first 8-bit MCUs optimised for popular low-power and battery-powered touch enabled LCD applications.
The PIC16F19197 family consists of 28- to 64-pin devices withup to 56 KB Flash and 4 KB RAM. The charge pump ensuresthat LCD screensmaintain consistent contrast even as battery voltage drops. The ADC2 automates signalacquisition 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. The PIC16F19197family is able to accomplish this entirely in hardware rather than relying upon software.
The family also features a Real Time Clock & 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. All of these features are offered along with the ability to drive up to 360 LCD segments, making the PIC16F19197 family an ideal choice for battery poweredLCD 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.”
