Note the following details of the code protection feature on Microchip devices: (cid:129) Microchip products meet the specification contained in their particular Microchip Data Sheet. (cid:129) 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. (cid:129) 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. (cid:129) Microchip is willing to work with the customer who is concerned about the integrity of their code. (cid:129) 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.

44-PIN DEMO BOARD USER’S GUIDE Chapter 1. 44-Pin Demo Board Overview 1.1 INTRODUCTION The 44-Pin Demo Board is a small and simple demonstration PCB for Microchip’s 44-pin Thin Quad Flatpack (TQFP) PICmicro® Microcontroller Units (MCU). It is populated with a PIC16F917 MCU, eight LEDs, push button and potentiometer. The demo board has several test points to access the I/O pins of the MCU and a surface mount prototyping area. The MCU can be programmed with the PICkit™ 2 Microcontroller Programmer or the MPLAB® ICD 2 using the RJ-11 to 6-pin inline adapter (AC164110). 1.2 HIGHLIGHTS This chapter discusses: (cid:129) Devices supported by the 44-Pin Demo Board (cid:129) The 44-Pin Demo Board Overview (cid:129) Running the Default Demonstration 1.3 DEVICES SUPPORTED BY THE 44-PIN DEMO BOARD The 44-Pin Demo Board can be used with virtually any 44-pin Thin Quad Flatpack (TQFP) PICmicro MCU. The assembled 44-Pin Demo Board is populated with a PIC16F917-I/PT microcontroller. Additional 44-Pin Demo Boards can be ordered from Microchip Technology and distrib- utors. Part number, DM164120-2, comes with one assembled and two blank 44-Pin Demo Boards. The blank demo board can be used for evaluating or prototyping circuits using any of the 44-pin devices listed below. 44-pin TQFP Flash Devices: (cid:129) PIC16F74 (cid:129) PIC16F747 (cid:129) PIC16F77 (cid:129) PIC16F777 (cid:129) PIC16F871 (cid:129) PIC16F874A (cid:129) PIC16F877A (cid:129) PIC16F917 (cid:129) PIC18F4220 (cid:129) PIC18F4320 (cid:129) PIC18F4331 (cid:129) PIC18F4410 (cid:129) PIC18F4420 (cid:129) PIC18F4431 (cid:129) PIC18F4450 (cid:129) PIC18F4455 (cid:129) PIC18F4480 (cid:129) PIC18F44J10 (cid:129) PIC18F4510 (cid:129) PIC18F4515 (cid:129) PIC18F4520 (cid:129) PIC18F4525 (cid:129) PIC18F4550 (cid:129) PIC18F4580 (cid:129) PIC18F4585 (cid:129) PIC18F45J10 (cid:129) PIC18F4610 (cid:129) PIC18F4620 (cid:129) PIC18F4680 © 2006 Microchip Technology Inc.

44-Pin Demo Board User’s Guide 1.4 44-PIN DEMO BOARD OVERVIEW The 44-Pin Demo Board is populated with a PIC16F917 MCU (U1), eight LEDs (DS1-DS8), push button (SW1) and potentiometer (RP1). The board layout is shown in Figure1-1. The demo board has several test points to access the I/O pins of the MCU and a surface mount prototyping area. The MCU can be programmed with the PICkit™ 2 Microcontroller Programmer from header P1. FIGURE 1-1: 44-PIN DEMO BOARD PICkit™ 2 Programming Header Push Button SW1 Potentiometer RP1 LEDs DS1-DS8 Surface Mount Prototyping Area 1.5 RUNNING THE DEFAULT DEMONSTRATION The assembled 44-Pin Demo Board comes preprogrammed with a demonstration program. To use this program, power the demo board (3.0 - 5.5VDC) using a PICkit™ 2 Microcontroller Programmer, or a bench power supply connected to header P2. To use the PICkit™ 2 Microcontroller Programmer, connect it to a PC USB port using the USB cable. Start the PICkit™ 2 Microcontroller Programmer PC application and click on the target power box to apply power to the demo board. The demo program will blink the eight red lights in succession. Press the push button switch, labeled SW1, and the sequence of the lights will reverse. Rotate the potentiometer, RP1, and the light sequence will blink at a different rate.
