Microchip Technology PIC16(L)F1847 Flash MCUs

Microchip PIC16(L)F1847 Flash MCUs are designed with an enhanced mid-range 8-bit CPU core with 49 instructions, 16 stack levels, and in-circuit debugging. These MCUs feature precision 32MHz internal oscillator block, ADC module, analog comparator, voltage reference model, programmable code protection, and data signal modulator module. The reference clock module enables sending a divided clock to the clock-output pin (CLKR) and provides a secondary internal clock source to the modulator module. The oscillator module has various clock sources and selection features, allowing it to be used in various applications while maximizing performance and minimizing power consumption. The PIC16(L)F1847 flash MCUs have a Capture/Compare/PWM peripheral module, which allows users to time and control different events and generate PWM signals. The debugging and programming support is available via PICkit™ 3 and MPLAB^® ICD 3.
