MC68341V

The MC68341 is a member of the M68300 family of integrated processors designed specifically for the compact disc-interactive (CD-I) market. It improves on the feature set of the MC68340 for a more complete and cost effective integrated system solution to CD-I's specific needs.

The MC68341 contains a 68020-based CPU32, a two channel DMA controller, two serial channels, a timer, and a queued serial peripheral interface. The 68341's system integration module (SIM41) contains clock circuitry, system protection, external bus interface, timers, and additional chip selects. New to the SIM is the real time clock and an MC68000 bus interface. The MC68000 bus interface is dynamically selectable to give a glueless interface to peripherals and memory designed for the MC68000 while allowing higher performance transfers using the standard 68300 bus interface. Complete code compatibility with the MC68000 affords the designer access to a broad base of established real-time kernels, operating systems, languages, applications, and development tools-many oriented towards embedded control.

As a low voltage part, the MC68341V can operate with a 3.3-V power supply and is particularly useful for applications. MC68341 is used throughout this document of MC68341V to refer to both the low voltage and standard 5-V parts since both are functionally equivalent.
