Microchip PIC16F18854 Microcontroller (MCU)

Full-featured for a wide range of general purpose and low-power applications

The PIC16(L)F18854 microcontrollers by Microchip feature Analog, Core Independent Peripherals and Communication Peripherals, combined with eXtreme Low-Power (XLP) technology for a wide range of general purpose and low-power applications.

Microchip is ADAS

The family features the CRC/SCAN, Hardware Limit Timer (HLT) and Windowed Watchdog Timer (WWDT) to support customers looking to add safety to their application. Additionally, this family includes up to 7 KB of Flash memory, along with a 10-bit ADC with Computation (ADC2) extensions for automated signal analysis to reduce the complexity of the application.
