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. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.

Chapter 1. F1 Evaluation Platform Overview
1.1 INTRODUCTION
Thank you for choosing the F1 Evaluation Platform. This kit allows you to begin
development using the PIC16LF1937 microcontroller (MCU).
The PIC16LF1937 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 derivatives feature an enhanced CPU, support for extended amounts of
memory, improved peripherals, and XLP low power. The F1 Evaluation Platform allows
you to evaluate these features for your application in a simple, low-cost platform.
This chapter introduces the F1 Evaluation Platform:

1.2 PLATFORM CONTENTS
The F1 Evaluation Platform contains the following items:
1. F1 Evaluation Platform Demo Board – www.microchip.com/
1.3 HARDWARE FEATURES
The F1 Evaluation Platform has the following hardware features:
1.3.1 PIC16LF1937
The PIC16LF1937 is a 40-pin full-featured device, including:
1. Enhanced PIC16 instruction set
2. 8K Words of Flash memory
3. 512 bytes of RAM
4. 256 bytes of EEPROM
5. 2 CCPs and 3 enhanced CCPs
6. MSSP (I
7. Enhanced USART
8. 8- and 16-bit timers
9. 32 MHz internal oscillator
10. Low-power 32 kHz crystal oscillator and
11. LCD controller.

C™, SPI)
F1Eval
1.3.2 MCP9800 I2C Temperature Sensor
The MCP9800 is a low-power, I2C temperature sensor with selectable 9 to 12 bits of
output resolution.

F1 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 PIC16LF1937 MCU using the PICkit ISCP™ header.
1.3.4 PICkit Serial Communications Header
The PICkit serial is a low-cost development tool that allows I2C, SPI and USART
protocols to be monitored and debugged through a simple 6-pin connector.
1.3.5 1 Button, 1 Potentiometer, 4 LEDs
Simple applications need the basic user interface elements. The button, potentiometer
and 1 LED are available for any application. The remaining 3 LEDs are shared with the
20-bit motor control expansion connector.
1.3.6 One 3.5 Digit LCD
The 3.5-digit LCD glass supplied on this board is a typical meter-type display with icons
for ohms, amps, etc. The PIC16LF1937 makes controlling the LCD very simple.
1.3.7 20-pin Motor Control Expansion Connector
This connector allows the PIC16LF1937 to control an optional Sensorless BLDC
add-on board (DM164130-2). The PIC16LF1937 has complete control of 3 phases so
other 1, 2, or 3-phase motor topologies can also be controlled.
1.3.8 Current Monitoring Connector
To demonstrate the Extreme Low Power (XLP) features of the PIC16LF1937, 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 PIC16LF1937 in your
application.

Chapter 2. Getting Started
2.1 INTRODUCTION
This chapter gives instruction to get your F1 Evaluation Platform powered up and
running the default demonstration. The following sections include:
• Powering the F1 Evaluation Platform
• Default Firmware
• Programming the F1 Evaluation Platform with the PICkit™ 3
• Attaching a PICkit Serial (optional)
• Measuring the current consumption

USER’S GUIDE
2.2 POWERING THE F1 EVALUATION PLATFORM
The PIC16LF1937 supplied with your F1 Evaluation Platform requires a supply voltage
of 1.8V-3.6V. Voltages above 3.6V will degrade or damage the device. There are four
ways to supply the necessary power.
1. Use PICkit 3,
2. Use the power connector at JP3,
3. Use PICkit Serial, or
4. Use the BLDC Expansion Header J3.
2.3 POWERING WITH PICkit™ 3
To power with the PICkit 3, perform the following steps:
1. Make sure a jumper or an ammeter is connected across JP2.
2. If you are using a BLDC expansion, remove the jumper at JP1.
