PIC16F19195-I/PT

PIC16(L)F19195/6/7 microcontrollers offer eXtreme Low-Power (XLP) LCD drive coupled with Core Independent Peripherals (CIPs) and Intelligent Analog. They are especially suited for battery-powered LCD applications due to an integrated charge pump, high current I/O drive for backlighting, and battery backup of the Real-Time Clock/Calendar (RTCC). Active clock tuning of the HFINTOSC provides a highly accurate clock source over voltage and temperature. The family also features a new 12-bit ADC controller which can automate Capacitive Voltage Divider (CVD) techniques for advanced touch sensing, averaging, filtering, oversampling and automatic threshold comparison. Other new features include low-power Idle and Doze modes, Device Information Area (DIA), and Memory Access Partition (MAP). These low-power products are available in 64 pins to support the customer in various LCD and general purpose applications.
