68HC11D3: Microcontroller

 

The MC68HC11D3 and MC68HC11D0 are ROM-based high-performance microcontrollers (MCUs). Members of the HC11D-series are derived from the same mask and feature a high speed multiplexed bus capable of running at up to 3 MHz, and a fully static design that allows operations at frequencies to dc.
