Electromagnetic Compatibility (EMC)

Compliance

The ‘IO-CON-1 / 2 / 3 Modules’ are CE Approved products. They are designed for use in an ESD

controlled environment i.e. development or production. This means, therefore, that the user must

ensure that there is no possibility of damage from electrostatic discharge (ESD). Since the devices

and equipment to which this product is likely to be connected may well themselves be susceptible to

ESD, this should not pose any difficulty.

For example, if you are handling microcontrollers and EEPROMS etc. then you will already be used to

appropriate precautions, such as the use of anti-static mats, wrist straps and so on. You should treat

your ‘IO-CON Modules’ with the same care as you would these types of devices. Always ensure that

you are not yourself carrying a static charge before handling the product. Wearing an earthed anti-

static wrist strap is recommended.

Equinox have taken great care in designing this product to be compliant with the European EMC

directive. When using the equipment be sure to follow the instructions provided. Although RF

emissions are within prescribed limits, care should be taken if you are using the product near to

sensitive apparatus. If you experience any difficulty please refer to Equinox Technical Support.

ESD Points to remember

•Work in a static-free environment.

•Wear an earthed wrist strap when handling either the programmer and/or

any programmable device.

•Ensure that the PC, programmer and Target system are connected to the

same EARTH (0V) potential.

•Do NOT plug the ISP cable of the programmer into a Target System when

the Target power is ON.

Warning!

Any damage caused to the programmer by Electrostatic Discharge (ESD) through inadequate

earthing is not covered under the warranty of the product.

I/O Connector Modules (IO-CON) for the PPM3 Programming Module – V1.04 – 1st April 2008

3.0 ISP Header Selection

3.1 Overview

The method of connection to the Target System or Test Fixture is usually dictated by the interconnect

method already used on the Target System or Test Fixture. If the programmer is to be interfaced

directly to a header on a Target System, then it is likely that one of the 6-wy or 10-way ISP box

headers will be used. If, however, the programmer is to be interfaced to a Test Fixture, then ‘Wire-

wrap’ or ‘Fast Connect’ clip-in connects are more likely to be used.

The choice of possible headers and connection systems are detailed in section 3.1.

The available headers for a particular device manufacturer / device type are detailed in section 3.2.

3.2 ISP Header Selection Chart (by header)

The various ISP Headers featured on the EQ-IO-CON modules are detailed in the table below. Please

3.4 Atmel 6-way ISP Header (SPI Interface)

This connection method is suitable for interfacing the programmer to a Target System which features

the following:

•Atmel 6-way IDC ISP Header

•An Atmel device which features the 3-wire SPI + RESET Programming Interface

The 6-way IDC box header is the most compact header i.e. takes up least space on the Target

System and so is very popular for designs where PCB space is limited. Unfortunately, this connection

method does not have any pins spare for extra functionality such as the SCK2 Oscillator so it should

only be used if this functionality is not required.

To implement this connection method, simply plug a 6-way ISP cable (not supplied) into the 6-way

ISP header and plug the other end of the cable into the matching header on the Target System.

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:

•Equinox 10-way IDC ISP Header

•An Atmel ATtiny microcontroller e.g. ATtiny11/12/15

•Suitable connections to implement ‘High Voltage Serial Programming Mode’.

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.

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

catastrophic damage to the Programmer & Target
