PIC16F887 Microcontroller

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, 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.

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.
