Microchip, 8 bit PIC, PIC16F18855 Microcontroller, 32 MHz, 14kB FLASH, 28-Pin QFN

The PIC16F range of Microcontrollers from Microchip are 8-bit MCUs that incorporate Microchip’s PIC® architecture into a variety of pin and package options.

PIC16F1885x/1887xx Microcontrollers are based on Microchip’s Enhanced Mid-Range core and are the first to include multiple new Low-Power features. IDLE and DOZE modes have been added along with Peripheral Module Disable, this allows peripherals to be removed from the power rail and clock tree for zero power leakage.

Additionally these devices are Microchip’s first PIC MCUs to incorporate an Analogue-to-Digital Converter with computation (ADC2). Functions like accumulation, averaging and low-pass filter calculations are completed in the ADC hardware instead of the MCU software, freeing up the CPU to sleep or complete other tasks.
