STK64+ - ATmega64 MCU AVR Development Board

The STK64+ is a complete, cost-effective development board for the ATmega64. It is designed to provide designers a quick start to develop code for the ATmega64 MCU, expediting the prototype development of ATMega64 devices.

The ATmega64 chip is mounted on a device board, which can be separated from the motherboard, allowing the secure exchange of the MCU. The ATmega64 chip comes in a TQFP64 package and can be the ATmega64-16AU, ATmega64L-8AU, or ATmega64A-A8U.

The STK64+ package comes with an ATmega64 device board, an additional spare ATmega64 device board, and an Experiment Fittings Pack.

STK64+ - ATmega64 MCU AVR Development Board - Components

• Power

  • Powered from external 5V power supply
  • Jumper for configuring voltage level to be applied, 5V/3.3V

• Onboard Chips

  • ATmega64 (TQFP64), MCU, mounted on the device board
  • AMS1117-3.3, on board regulator
  • MAX3232, True RS232 Transceivers

• Interfaces

  • Two RS232 connector for UART0 and UART1, DB9 standard
    • Guaranteed to operate under 3V level supply thanks to the MAX3232
    • UART0 and UART1 jumpers, short the jumper to connect UART to AVR MCU, open the jumper to vacate the I/O ports.
  • 6-pin / 10-pin ISP port
  • JTAG port

• Human to Machine Interface

  • RESET button, used to reset the MCU
  • Power indicator LED
  • 8 surface mounted LEDs, can be used as I/O status indicator
  • 8 Push-buttons, for analog input

• Other Features

• Crystal configurable, there is a jumper for selecting on board 7.3728M crystal or external crystal mounted via the socket
• All the MCU pins are accessible on expansion connectors for further expansion
• All the pins are marked on the board. These marks describe the function of each pin
• Compatible with several AVR MCUs:
• Fully compatible with: ATmega64/ATmega128
• Partly compatible with: ATmega1281/ATmega2561, AT90CAN32/AT90CAN64/AT90CAN128

The AVR Microcontroller and Embedded Systems Using Assembly and C

The AVR microcontroller from Atmel (now Microchip) is one of the most widely used 8-bit microcontrollers. Arduino Uno is based on AVR microcontroller. It is inexpensive and widely available around the world. This book combines the two. In this book, the authors use a step-by-step and systematic approach to show the programming of the AVR chip. Examples in both Assembly language and C show how to program many of the AVR features, such as timers, serial communication, ADC, SPI, I2C, and PWM.

The text is organized into two parts:

• The first 6 chapters use Assembly language programming to examine the internal architecture of the AVR.
• Chapters 7-18 uses both Assembly and C to show the AVR peripherals and I/O interfacing to real-world devices such as LCD, motor, and sensor.

The first edition of this book published by Pearson used ATmega32. It is still available for purchase from Amazon. This new edition is based on Atmega328 and the Arduino Uno board.
