STK505 Description

Short technical summary and product information.

The Atmel STK505 is an evaluation board categorized under Embedded - MCU, DSP. It is designed to facilitate the development and testing of microcontrollers and digital signal processors.

 

The board supports an operating voltage range of 2.7V to 6.0V, making it versatile for various power supply configurations. In-System Programming (ISP) is supported, allowing code to be downloaded into flash and EEPROM memory using the AVR internal SPI. This programming method requires minimal connections: VCC, GND, RESET, and three signal lines.

 

The STK505 is suitable for programming a wide range of AVR devices, with exceptions for AT90C8534, ATtiny11, and ATtiny28. It can program both internal flash and EEPROM, as well as fuse bits for clock options, startup time, and the Brown Out Detector (BOD).

 

For programming, the device utilizes standard programming headers and a 6-wire cable. Specific headers like ISP6PIN, SPROG1, SPROG2, and SPROG3 are used depending on the AVR device and socket type. The ISP frequency (SCK) should be less than 1/4 of the target clock frequency, with a recommended setting of 1/5 or less for optimal performance on the Atmel STK500.
