4.5 J6(a) - Equinox 10-way Header (Generic SPI Interface)
This connection method is suitable for interfacing the EPSILON5 programmer to a Target System
which features the following:
•
Equinox 10-way IDC ISP Header
•
An Atmel device which features the 3-wire SPI + RESET Programming Interface
This is the favoured ISP connector as it allows the following additional functions:
•
Application of +12V Vpp for ATtiny High Voltage Serial Programming
•
SCK2 Oscillator for clocking devices during programming
•
Spare I/O pin which could be used for SPI SLAVE SELECT or to drive an LED on the Target
System
To implement this connection, simply plug the 10-way ISP cable into the EPSILON5 J6 header and
plug the other end of the cable into the matching header on the Target System.

Warning!
1. It is possible for +12V to be output on pin 10 of this
connector when programming ATtiny11/12/15 devices.
2. Connecting to the wrong ISP Header may cause

Description
Target VCC
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.
Spare Programmer I/O pin
This pin is currently a I/O spare pin
which is not used during SPI
programming. In order to use this pin,
the pin state must be setup in the
EQTools <Pre-programming State
Machine> tab.
