Cyclone interface speeds debugging and programming

Now available from Computer Solutions, the MON08 Cyclone is a stand-alone automated programming and debugging interface unit for use with the 68HC08 microprocessor family.

The new unit links a PC serial port to the processor's MON08 monitor port for testing programs and programming those chips containing Flash memory or EEPROM.

It offers significant benefits over the Motorola RS232 interface circuit, which has limited functionality.

The Cyclone interface provides very high-speed programming at up to 3Kbyte/s and check-sum tests at up to 12Kbyte/s.

It operates with target voltages of 2-5V, and provides automatic detection of target frequency and baud rate as well as providing a clock for the target if required.

Three operating modes are available.

Windows-based user-driven or script-driven debugging and flash-programming software is supplied with the Cyclone interface.

Alternatively, the unit can be linked to a PC to download a program image, and then disconnected for use as a stand-alone programmer.

The MON08 configuration is initialised on reset, and automatic power sequencing of the target is provided to control security access.
