2 Introduction Thank you for buying our ISPcable II programmer. We hope that the great power it offers will allow you to appreciate fully the virtues of programming in the system provided by Atmel microcontrollers. ISPcable II is advanced, high-speed development/production programmer supporting most In-System Programmable microcontrollers from Atmel. ISPcable II gives the designer a compact and realiable programming tool to program most In-system Programmble Atmel microcontrollers through a - or 0-pin ISP connector. The programmer connects to a PC through a standard RS serial interface and draws the necessary power from the target board eliminating the need for an additional power supply. Maximum speed of RS and SPI interfaces are chooses automaticly for programming with maximum accessible for programmed mikrocontroller speed. ISPcable II can co-operate with microcontrollers supplied with voltages from. to V. Such a broad range of supply voltages was achieved through buffering of signals on the ISP line, additionally enhancing the immunity of the circuit to interference. ISPcable II is provided with ProProgRS software working in the Windows system, it co-operate with AVRStudio (AVR Prog -not all microcontorllers) software from Atmel as well. Moreover, functions offered by ProProgRS are available, such as: programming and read-out of Flash memories, EEPROM, fuse-and-lock bits, RESET signal configuration, SPI frequency. Due to the small size, it is also an excellent tool for field upgrades of existing applications Let us wish you nothing but success and a lot of satisfaction in designing and putting new microprocessor devices to work. Features Connects to standard PC comm port Fast programming with auto-adapting or manual RS clock auto-adapting or manual SPI clock Programming software can be easily upgraded to support future devices, if necessary. Support will be added as soon as new devices become available. Operates with target voltages in the range of. - V Buffering of the ISP bus, allowing proper operation with systems powered from a broad range of supply voltages and enhancing immunity to external interference Operation of the programmmer signalized by built-in indicator Standard 0-pin connector to the target circuit in the Atmel standard Draws power from target, or external power Small size Supports RC Oscillator Calibration Programs both Flash and EEPROM Security and Fuse Bit programming supported EEPROM and all Fuse and Lock Bit options ISPProgrammable can be programmmed individually or with the sequential automatic programming option

6 Connection with the target circuit The connection to the target circuit should be realized through the attached 0-lead ribbon cable, terminated with standard IDC plugs with. mm raster. In case of using another cable it should be kept in mind that it should not be longer than 0 cm (~ inches). The target device should be equipped with a ISP connector with lead-out identical to that of the programmer ISP connector. We connect the ISP bus lines with their corresponding ISP bus lines of the microcontroller as shown in the figure below.

7 Level converter of ISP signals In order to assure proper operation of the programmer when the supply voltages of the target circuit differ from the programmer s supply voltage, level converters of ISP signals come into use. The conversion circuits have been designed for operation with a target circuit supplied from a voltage between. and V. The ISPcable II can be supplied from an external source or directly from the target circuit. In the last case, the supply voltage should have a value between. and. V. Signals between the programmer and the target circuit can be divided into two groups: input signals (MISO), output (MOSI, SCK, RST, ). Besides regenerating ISP bus signals, the signal level converter buffers limit the input and output currents. Buffering has been applied on all signal lines of the programmer. The implementation of a signal level converter for output lines has been shown in the figure below. VCC From uc R To Target ISP HEADER ZENER Voltage level converter (outputs) The implementation of a signal level converter in the input line of the MISO programmer is shown below.

8 Supplying the programmer Programmer unit can be powered on two ways: By the ISP connector from target circuit. In this case the power voltage system should be since. to. V, Power jumper must be close. Bye external power supply connected to POWER of programmer. In this case power voltage system should be since. to V, after closing power jumper, power to the target circuit can be supplied, the maximum current is 0 ma. However power supply programmer unit should be done across connector about diameter of pin. mm. The Voltage should be since to V for DC and since to for AC. The implementation of arrangement of the power supply inside the programmer unit ISPcable II was showed on following drawing.
