PIC16(L)F18855/75
Full-Featured 28/40/44-Pin Microcontrollers
Description
PIC16(L)F18855/75 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 14 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.
