Guidelines for Getting Started with PIC16F152 Microcontrollers

4.1

Basic Connection Requirements

Getting started with the PIC16F152 family of 8-bit microcontrollers requires attention to a minimal set of device pin

connections before proceeding with development.

The following pins must always be connected:

• All VDD and VSS pins (see “Power Supply Pins”)

• MCLR pin (see “Master Clear (MCLR) Pin”)

These pins must also be connected if they are being used in the end application:

• PGC/PGD pins used for In-Circuit Serial Programming

™ (ICSP™) and debugging purposes (see “In-Circuit Serial

Programming (ICSP) Pins”)

• CLKIN pin when an external clock source is used.

Additionally, the following may be required:

• VREF+/VREF- pins are used when external voltage reference for analog modules is implemented

The minimum recommended connections are shown in the figure below.

Power Supply Pins

4.2.1

Decoupling Capacitors

The use of decoupling capacitors on every pair of power supply pins (VDD and VSS) is required.

Consider the following criteria when using decoupling capacitors:

• Value and type of capacitor: A 0.1 μF (100 nF), 10-25V capacitor is recommended. The capacitor should be a

low-ESR device, with a resonance frequency in the range of 200 MHz and higher. Ceramic capacitors are

recommended.

• Placement on the printed circuit board: The decoupling capacitors should be placed as close to the pins as

possible. It is recommended to place the capacitors on the same side of the board as the device. If space is

constricted, the capacitor can be placed on another layer on the PCB using a via; however, ensure that the trace

length from the pin to the capacitor is no greater than 0.25 inch (6 mm).
