Freescale 8-bit Architectures

RS08
Efficient and cost effective, this core was designed for small packages devices under 16k.
HC08
From a basic bare-bones controller in a tiny 8-pin quad flat no-lead (QFN) package to feature-rich silicon in a 64-lead quad flat package (QFP), core is an industry workhorse flaunting an impressive array of peripherals.
HCS08
This high-performance core is optimized for extreme operating economy and boasts several low-power options, which is particularly attractive for battery-powered and handheld applications.
