I/O Connector Modules (IO-CON) for the PPM3 Programming Module – V1.04 – 1st April 2008 1 Equinox Warranty Information This product is guaranteed by Equinox Technologies UK Limited for a period of 12 months (1 year) after the date of purchase against defects due to faulty workmanship or materials. One guarantee covers both parts and labour. Service under the guarantee is only provided upon presentation of reasonable evidence that the date of the claim is within the guarantee period (e.g. completed registration/guarantee card or a purchase receipt). The guarantee is not valid if the defect is due to accidental damage, misuse or neglect and in the case of alterations or repair carried out by unauthorised persons. A number of exceptions to the warranty are listed in the ‘Exceptions to warranty’ section below. Service (during and after guarantee period) is available in all countries where the product is distributed by Equinox Technologies UK Limited. Exceptions to warranty Over-voltage damage This warranty does not cover damage to the programmer due to voltages beyond the specified voltage limits being applied to the ‘DC Power Input’ (CON1) or any of the ISP Headers. The user must ensure that sufficient care is taken to avoid over-voltage and static conditions on any of the ‘ISP Header’ I/O pins. Over-current damage This warranty does not cover damage to the programmer due to excessive current being drawn from the programmer power supply. The user must ensure that there is sufficient over-current protection within the test fixture to protect against short circuit loads. Short-circuit damage This warranty does not cover damage to the programmer due to short-circuit loads being placed across programmer I/O lines. Warning! Any damage caused to the programmer by Electrostatic Discharge (ESD) through inadequate earthing is not covered under the warranty of the product. 2 I/O Connector Modules (IO-CON) for the PPM3 Programming Module – V1.04 – 1st April 2008 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 antistatic 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 7 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 ‘Wirewrap’ 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 refer to the section indicated in the ‘refer to section’ column for specific details of each header. # I/O Description / Function Connector Module 1 IOCON-1 IOCON-2 IOCON-3 Atmel 6-way ISP Header Refer to section ISP Header Pin-out 3.4 Device support: • Atmel AT90S, ATmega, ATtiny AVR microcontroller • AT89S microcontrollers • 24Cxxx Serial EEPROM The ‘Equinox’ Header can have THREE different pin-outs depending on which Target Device is to be programmed.

The information contained in this manual does NOT show the actual connections to the Target Microcontroller. Please refer to the separate Application Notes ( see App Note column in table below ) for full details of how to implement In-System Programming for your selected device. Please note: • The Atmel ATmega16 / 32 / 64 / 323 / 128 / 169 devices can be programmed via ‘LV SPI’ or ‘JTAG’ by connecting the relevant header to the SPI or JTAG port of the device. • The so-called ‘Equinox Header’ is multi-functional. The pin-out of this header is different depending on which device type is being programmed. # Device Family Devices 1 Atmel AT89S AT89(L)S51/52/53/8252 LV SPI IOCON-1 • Equinox 10-way header • Atmel 10-way header • Atmel 6-way header • Fast-Connect header IOCON-2 • Equinox 10-way header • Atmel 10-way header • Atmel 6-way header • Wire-wrap header (J25) IOCON-3 • Equinox 10-way header • Atmel 10-way header • Atmel 6-way header • Fast-Connect header 2 Atmel AT90S (AVR) All AT90S ISP devices LV SPI Same as (1) 3 Atmel ATmega (AVR) All ATmega devices (using SPI port for programming) LV SPI Same as (1) Use IO-CON-3 if JTAG support is also required. 4 Atmel ATmega (AVR) ATmega with JTAG port JTAG for programming 10 Algorithm Required IO-CON Module + ISP Header IOCON-3 • JTAG 10-way header • Fast Connect Headers (J3 & J4) • The Equinox 10-way header on this module can be used for SPI programming.

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.

This cable is terminated with a 10-way IDC 0.1” female polarised plug at each end. The cable is wired as a so-called ‘straightthrough’ cable with pin 1-1, 2-2 etc. The polarised ISP Header ensures that the ISP Cable cannot be plugged in the wrong way around by mistake. If you are planning to design such a header onto your Target System, it is strongly recommended that a similar polarised header is used. This will help to prevent accidental damage to both the programmer and the Target System. Pin 1 of the ISP cable can be determined by looking for a small arrow on the plastic part of the ISP female plug. If the cable has a RED stripe on one cable, this usually also indicates pin 1. If you are using the programmer in a production environment and constantly plugging / unplugging the ISP cable into/from the Target System, you may find that the cable eventually fails. Spare ISP cables can be ordered from Equinox in this eventuality. 26 I/O Connector Modules (IO-CON) for the PPM3 Programming Module – V1.04 – 1st April 2008 5.0 Power Connections + Vcc Sense 5.1 Overview The PPM3 programmer supports the following power supply options: # Description 1 Programmer provides controlled power (3.0 – 5.0V) to the Target System 2 Programmer provides static +5V DC to the Target System 3 Programmer and Target System are independently powered 4 Target System powers the Programmer (+5V DC only) The setup for the above Power Supply Options is beyond the scope of this manual.
