Description

General part information

PIC16LF18456 Series

The PIC16(L)F184xx 8-bit product family features high resolution Analog, Core Independent Peripherals (CIPs) and communication along with eXtreme Low-Power (XLP) technology for a wide range of general purpose and low-power applications. The family offers a 12-bit ADC with computation (ADC2), multiple communications interfaces, a temperature sensor; along with memory features like Memory Access Partition (MAP) and Device Information Area (DIA). The 12-bit ADC2 automates Capacitive Voltage Divider (CVD) techniques for advanced touch sensing, averaging, filtering, oversampling and automatic threshold comparison. The products also have a highly effective power management features such as CPU IDLE/DOZE modes, peripheral module disable (PMD) and peripheral pin select (PPS).
