DS89C430 MTK2 APPLICATION
The DS89C430 is an ultra-high-speed 8051-compatible microcontroller from Maxim Integrated
Products. One unique feature of DS89C430 microcontroller is that it has a ROM loader mode
which can be used to program the microcontroller itself.
According to the user’s guide, UART0 (pin 10 and pin 11) is invoked in ROM loader mode when
RST is set to High and both EA and PSEN are set to LOW simultaneously. After the ROM loader
mode is enabled, serial communication can be handled between a PC’s RS-232 port and the
microcontroller using a RS-232 transmitter/receiver such as MAX232.
In order to program the DS89C430 Microcontroller the following software must be installed on
your Windows XP computer. Please download the application from the following website;
