Note the following details of the code protection feature on Microchip devices:

• Microchip products meet the specification contained in their particular Microchip Data Sheet.

• Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the intended manner and under normal conditions.

• There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data Sheets. Most likely, the person doing so is engaged in theft of intellectual property.

• Microchip is willing to work with the customer who is concerned about the integrity of their code.

• Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not mean that we are guaranteeing the product as “unbreakable.”

Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our products.

Chapter 1. F1 LV Evaluation Platform Overview

1.1 INTRODUCTION

Thank you for choosing the F1 LV Evaluation Platform. This kit allows you to begin development using the PIC16LF1947 microcontroller (MCU).

The PIC16LF1947 is the first in a family of enhanced mid-range microcontrollers. These architectural enhancements allow for more memory and faster computation than that of legacy PIC16 microcontrollers.

The PIC16F1 and PIC12F1 family of microcontrollers are a series of 8-bit microcontrollers derived from the popular PIC16 series of 8-bit PIC The F1 LV derivatives feature an enhanced CPU, support for extended amounts of memory, improved peripherals, and XLP low power. The F1 LV Evaluation Platform allows you to evaluate these features for your application in a simple, low-cost platform.

F1 LV Evaluation Platform User’s Guide

1.3.3 PICkit™ 3 Programming/Debug Header

The PICkit 3 is a low-cost development tool that allows programming and debugging of the PIC16LF1947 MCU using the PICkit ICSP™ header.

1.3.4 MCP2200 USB to Serial Converter

The MCP2200, with the associated driver, makes the F1 LV Evaluation platform appear as a serial port when connected to a PC. The demo code includes utilities to control the various add-on boards through this serial interface.

1.3.5 Two Push Buttons, One Potentiometer, 7 LEDs

Simple applications need the basic user interface elements. Two push buttons, one potentiometer and 4 green LEDs are available for any application. The remaining three LEDs are used as indicators, a red LED is used to indicate the board is powered, the remaining two LEDs are green and indicate RX/TX communication through the USB Serial Converter.

1.3.6 One Custom LCD

The LCD glass supplied on this board is a Microchip custom display with icons for a battery indicator, 4 large numerical digits, 2 small numerical digits, adjustable decimal point, colon for time keeping, 4 function mode (Fx) indicators, 8 segment bar, a three-segment battery power indicator and 1 custom Microchip symbol. The PIC16LF1947 makes controlling the LCD very simple.

1.3.7 20-pin Add-on Connector

This connector expands the F1 LV Evaluation Board with optional add-on boards. Currently, there are 4 motor control add-ons planned or in production. The PIC16LF1947 has complete control of 3 phases, so other 1, 2, or 3-phase motor topologies are supported.

1.3.8 Current Monitoring Connector

To demonstrate the Extreme Low Power (XLP) features of the PIC16LF1947, a precision ammeter can be connected to the current monitoring connector. This allows your application to be easily optimized for the lowest possible current.

1.3.9 Generous Prototyping Area

Our circuits are not your circuits. A prototyping area has been provided to extend the functionality of this demo board to demonstrate the utility of the PIC16LF1947 in your application.

1.3.10 MCP1640 Synchronous Boost Regulator

The MCP1640 is a compact, high-efficiency, fixed frequency, synchronous step-up DC-DC converter. Through the use of this component, the F1 LV Evaluation board has the option of boosting an AAA 1.8V battery to 3.3V, which is then used to power the board and supporting circuitry.

1.3.11 MCP1703 LDO Regulator

The MCP1703 is a low-dropout voltage regulator with a 250 mA maximum output. Through the use of this component, the user has the option of powering the F1 LV Evaluation board through the USB Serial Converter connector. The USB supplies 5V, and the MCP1703 reduces this to the operating voltage of 3.3V.

F1 LV Evaluation Platform Overview

1.3.12 User Selectable Power Sources

The F1 LV Evaluation board operates at 3.3V and comes with a flexable range of powering options.

• J5 – (EXT SUPP) The user can power the board from a external power supply connected to the +/- headers.

• J6 – (EXP PWR) The user can power the board from any Add-on board through the expansion connector.

• J7 – (AAA BATT) The user can power the board by inserting a single AAA battery into B1 battery clamp.

• J8 – (USB PWR) The user can power the board by connecting a USB cable to J2 USB SERIAL CONV header.
