PIC16F18857-I/SP中文资料微芯科技数据手册PDF规格书

描述 Description

PIC16(L)F18857/77 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 56 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.
