The 40-pin IC has 14 Channel 10-bit ADC making it suitable for applications that require more ADC inputs. The IC also has 2 Comparators, 2 Timers (8-bit and 16-bit) and supports SPI, I2C, and UART communication protocols. PIC16F887 Microcontroller Overview The PIC16F887 is an 8-bit microcontroller from Microchip. The 40-pin IC has 14 Channel 10-bit ADC making it suitable for applications that 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. The IC also supports safety features like Power-on Reset (POR), Brown-out Reset (BOR), Low Current Watchdog Timer (WDT), etc making it suitable for task-critical and industrial applications. The controller supports In-Circuit Serial Programming (ICSP) allowing the designer to program the controller easily even without removing it from the actual circuit. Features PIC16F887 –Simplified Features CPU 8-bit PIC Number of Pins 40 Operating Voltage (V) 2 to 5.5 V Number of I/O pins 35 ADC Module 14ch, 10-bit Timer Module 8-bit(2), 16-bit(1) Comparators 2 DAC Module Nil Communication Peripherals UART(1), SPI(1), I2C(1), MSSP(SPI/I2C) External Oscillator Up to 20Mhz Internal Oscillator 8Mhz to 32KHz Program Memory Type Flash Program Memory (KB) 14KB CPU Speed (MIPS) 5 MIPS RAM Bytes 368 Data EEPROM 256 bytes the most pins are multi-functional. For example, designator RA3/AN3/Vref+/C1IN+ for the fifth pin specifies the following functions: RA3 Port A third digital input/output AN3 Third analog input Vref+ Positive voltage reference C1IN+ Comparator C1positive input This small trick is often used because it makes the microcontroller package more compact without affecting its functionality. These various pin functions cannot be used simultaneously but can be changed at any point during operation. The following tables, refer to the PDIP 40 microcontroller.
