PIC16F887 Microcontroller from Microchip. The 40-pin IC has 14 Channel 10-bit ADC making it suitable for applications which require more ADC inputs. The IC also has 2 Comparators, and 2 Timers (8-bit and 16-bit) and supports SPI, I2C and UART communication protocols.
It can operate at a speed of up to 20MHz with an external oscillator and also has a precision internal oscillator tunable between 8MHz to 32kHz. The IC supports nanoWatt technology allowing it to consume very low power and operate in Power-Saving sleep mode. It also has a wide operating voltage from 2V to 5.5V making it suitable for battery-powered applications
