Hot sale Original P89C668HFA IC 8-BIT FLASH 33 MHz MICROCONTROLLER PQCC44 PLASTIC Microcontroller

Product Description

The P89C660/662/664/668 device contains a non-volatile 16KB/32KB/64KB Flash program memory that is both parallel programmable and serial In-System and In-Application Programmable. In-System Programming (ISP) allows the user to download new code while the microcontroller sits in the application.

In-Application Programming (IAP) 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 In programming, the user program erases and reprograms the Flash memory by use of standard routines contained in ROM.
