DS89C420
Flash programming is executed by a series of internal flash commands that are derived (by the built-in
ROM loader) from data transmitted over the serial interface from a host PC. PC-based software tools that
configure and load the microcontrollers are available at www.maxim-ic.com/micros/ftpinfo.html.
Full details of the ROM loader software and its implementation are given in the Ultra-High-Speed Flash
Microcontroller User’s Guide.
