4.8 J7 - Atmel 10-way Header (SPI Interface)
This connection method is suitable for interfacing the programmer to a Target System which features
the following:
•
Atmel 10-way IDC ISP Header
•
An Atmel device which features the 3-wire SPI + RESET Programming Interface
This connector is compatible with the Atmel STK200, STK300 and STK500 Starter Kits. Equinox
would recommend not using this connector on new designs, but instead using the 'Equinox 10-way
Header' as the Equinox header caters for an External Oscillator, Vpp switching and also features a
spare I/O pin for future expandability.
To implement this connection, simply plug the 10-way ISP cable into the Programmer ISP Header J7
and plug the other end of the cable into the matching header on the Target System.

Description
Master Out Slave In
This is the SPI data output pin from the
programmer. This pin should be
connected to the MOSI pin on the Target

This pin should be connected to the
Target System Vcc. This voltage could
be used to power the programmer
depending on the settings of the power
switch/jumper on the programmer.
Not connected
