Product Summary

The P89C664HB is a Flash microcontroller. It contains a non-volatile 32KB Flash program memory that is both parallel programmable and serial In-System and In-Application Programmable. In-System Programming (ISP) of the P89C664HB allows the user to download new code while the microcontroller sits in the application. In-Application Programming (IAP) of the P89C664HB means that the microcontroller fetches new program code and reprograms itself while in the system. This allows for remote programming over a modem link. A default serial loader (boot loader) program in ROM allows serial In-System Programming of the Flash memory via the UART without the need for a loader in the Flash code. For In-Application Programming, the user program erases and reprograms the Flash memory by use of standard routines contained in ROM.
