Cybiko
The CPU is a Hitachi H8S/2323 running at 18 MHz. Just as with the original version, it also has an Atmel AT90S2313 co-processor running at 4 MHz so it can support RF communications. The Cybiko Extreme comes with 512KB ROM flash storage and 1.5MB RAM. It comes with an add-on slot in the back, but the only hardware released that can be connected to it is an MP3 player.
