AVRISP In-System ProgrammerThe AVR In-System Programmer (AVRISP) from Atmel is a professional low-cost In-System Programmer covering all avr 8 -bit RISC Microcontrollers.

The AVRISP can be divided inthree sections: The RS-232 interface, the Control section and the ISP cable.

6 In this sec-tion a brief overview of the different blocks will be 3-1. Simplified AVRISP Block Schematics Serial InterfaceThe AVRISP uses a standard female DSUB, RS-232 port for communication with thefront-end software (AVR Studio). It supports communication of 115200 SectionThe control MCU handles all communication between the target AVR and the front-endsoftware. The AVRISP is completely software controlled from AVR Studio. No manualconfiguration of the ISP is needed. A 3-color LED indicates the status of the AVRISP. During programming the LED is yel-low.

7 When the target AVR is successfully programmed, the LED will turn green. Ifprogramming fails, the LED will turn red to indicate that programming (or verification)CTRLMCURxDTxDGNDVTGRESETSCK MOSIMISORS-232 LevelVTGVTGGNDRxDTxDRS-232 InterfaceControl SectionISP CableTable 3-1.

Dur-ing start-up the status LED cycles through red, yellow to green to indicate that themaster MCU is Interface CablesAVRISP supports both the 6-pin header connector pinout, used by the Atmel AT90 ISPcable, and the 10-pin header connector used by the STK200 and STK300 developmentboards.

8 Figure 3-2 shows the pinouts for the 6-pin and 10-pin ISP is delivered with one 6-wire and one 10-wire ISP cable. Use the one that matchthe pinout of the target ISP connector. However, note that only one cable should be con-nected, and used, at any given time. By default the 10-pin header connector is 3-2. AVRISP Connectors (Top View) Power Requirements and ConsiderationsSince the AVRISP draws power from the target, it is important that the target board isable to provide enough power to ensure correct operation. The AVRISP will draw maxi-mum 50 mA @ The current is drawn through the VTG line.

9 The target should thusbe able to supply at least this amount of power in addition to the requirements of the tar-get board Technical Spesification section on page 8-1 for information on AVRISP is not equipped with a power switch. Power is turned on when AVRISP isconnected to the target application and turned off when AVRISP to Target BoardThe AVRISP connects to the target board through a 3 x 2 or 5 x 2 male header connec-tor with mm ( ) spacing (Figure 3-3). If there is a 6-pin or 10-pin ISP connectoron the target board, the cable on the AVRISP has to be changed accordingly.

10 The power of the target board should be turned off when connecting or disconnectingthe header connector. Hot-swapping is not supported and might damage 3-2.
