My optical Dell computer mouse (costs 10 Euro, when buying as additional
equipment with a PC) has a CY7C63813, even in DIP case. Arrow has the SOIC
version for $2.94 for single units. It has 8k flash and 256 bytes RAM. With
an optimizing C compiler I think it should be possible to implement a mouse
device for it in C. The M8C instruction set is more powerful than 8051, but
the core is slow. But doesn't matter for many applications.
