68HC705C9A : Microcontroller
The MC68HC705C9A HCMOS microcomputer is a member if the M68HC05 Family. The
MC68HC705C9A is the EPROM version of the MC68HC05C9A and can also be configuerd
as the EPROM version of the MC68HC05C12A. The MC68HC705C9A memory map consists
of 12,092 bytes of user EPROM and 176 bytes of RAM when configured as an
MC68HC05C9A. The MC68HC705C9A includes a serial communications interface, a serial
peripheral interface, and a 16-bit capture/compare timer.
