TSC 80251 Extended 8-bit Microcontroller
The Core Performance (1/5)
New Requirements for the 90’s and Beyond
• Higher performance to support sophistication of equipment
• Re-use of existing code due to big development investments
and software qualification
• Complex Software (memory space)
• Easier and efficient programming with "C" language
• Time to market with ASSP approach
• Less power consumption and noise
• System cost reduction

Features / Benefits
• Core fully licenced from INTEL
• C- Language optimized product
• Binary Code compatible with the 80C51 on
its lowest perf. level
• 64KB stack space
• 5 times faster than the 80C51 by using the
same code at same frequency
• Low overhead with C-language
• High instruction throughput with a new 3stage pipeline architecture (2 clocks per
basic instruction)

TSC 80251 Extended 8-bit Microcontroller
The Core Performance (4/5)
System Advantage
Use higher performance to reach new applications
•High-end 8-bit and 16-bit applications
•All applications with a high demand of controlling, computing or
dataprocessing performance:
Automotive: Airbag, Car-Navigation, Climate Control
Communication: Mobile phones, ISDN-phones, high speed Modems,
Network Termination
Computer: CD-ROM, high-end Monitors, Disk Drives
Reduce Operating frequency while maintaining high level of
CPU-power
•Decrease Power Consumption
•Limit the EMC problems
•Reduce Systemcosts (Crystal, Memory..)
Use CPU for additional tasks (DSP, DTMF, ..)
