3.6 Equinox 10-way Header (ATtiny11/12/15 HV Interface)
This connection method is suitable for interfacing the programmer to a Target System which features
the following:
The connector supports programming of the Atmel ATtiny11/12/15 microcontrollers in ‘High Voltage
Serial Programming Mode’. This mode requires that a +12.0V Vpp voltage is applied to the RESET
pin of the target device in order to enter programming mode.
To implement this connection, simply plug the 10-way ISP cable into the 10-way header marked
‘Equinox’ and plug the other end of the cable into the matching header on the Target System. Please
ensure that you have made the correct connections from the ISP Header to your Target Device.

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 spare I/O pin
which is not used during SPI
programming. In order to use this
pin, the pin state must be set up in
the EQTools <Pre-programming
State Machine> tab.
SCK2 Clock Output
This output pin is used to supply
an external clock signal (SCK2) to
the target microcontroller.
