Additional Details

The XC68HC705P6CP typically operates with a clock frequency of around 4 MHz. The specific memory sizes (ROM/EPROM and RAM) vary depending on the exact variant. The number of I/O pins and the features of the serial communication interface (SCI) also depend on the specific part number. Due to its legacy status, detailed specifications and programming information are readily available in the original Motorola datasheets. When using parts from Rochester Electronics, confirm that the device meets all of your design requirements. It is important to note that programming may require older programmers depending on the memory type used in the specific variant you are utilizing.
