4.8 J7 - Atmel 10-way Header (SPI Interface)

This connection method is suitable for interfacing the EPSILON5 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 EPSILON5 ISP Header J7
and plug the other end of the cable into the matching header on the Target System.
