M38K09RFS General Description
The 38K0 group is the 8-bit microcomputer based on the 740 family core technology.
The 38K0 group has the USB function, an 8-bit bus interface, a Serial I/O, three 8-bit timers, and an 8-channel 10-bit A-D converter, which are available for the PC peripheral I/O device.
The various microcomputers in the 38K0 group include variations of internal memory size and packaging. For details, refer to the section on part numbering.
