PIC16(L)F18854
Full-Featured 28/40/44-Pin Microcontrollers
Description
PIC16(L)F18854 microcontrollers 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.
The family will feature 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.
