Description



Features:

Based on the extended 8bit C251 Architecture, the TSC80251A1 includes a complete set of new or improved C51 compatible peripherals as well as a 4 channels 8bit A/D converter for communication with the analog environment.
The key features of the new C251 Architecture are:
Registerbased Architecture:
40byte Register File
Registers accessible as Bytes, Words, and Double Word.
3-stage instruction pipeline
Enriched Instruction Set
16bit and 32bit arithmetic and logic instructions
Compare and conditional jump instructions
Expanded set of Move instructions
Reduced Instruction Set
189 generic instructions
Free space for additional instructions in the future
Additionally all 80C51 instructions are usable in binary mode
16bit internal code fetch
64 Kbytes extended stack space
Maximum addressable memory 16 Mbytes
The benefits of this new architecture are:
5 times 80C51 performances in binary mode (80C51 binary code compatibility)
15 times 80C51 performances in source mode (full architecture performance)
Up to a factor 3 of code size reduction (when a C for 80C51 program is recompiled in C251 language)
Reduction of RFI and power consumption (reduced operating frequency)
Complete System Development Support
Compatible with existing tools
New tools available: Compiler, Assembler, Debugger, ICE
 Efficient C language support




Application

Typical applications for these products are CDROM, Card or Barcode readers, Monitors, Car Navigation Systems, Airbag and Brake Systems, as well as all kinds of Industrial Control and Measurement Equipment. With the high instruction throughput, the TSC80251A1 products are focussing on all highend 8bit to 16bit applications. They are also well suited to systems where a lower operating frequency is needed to reduce power consumption or Radio Frequency Interference (RFI), while maintaining a high level of CPUpower.

Description

The TSC80251A1 products are derivatives of the TEMIC Application Specific Microcontroller family based on the extended 8bit C251 Architecture described below.

This family of 80251A1 are tailored to Microcontroller applications requiring analog interface structures.

Three major peripheral blocks have been implemented to provide this 80251A1 to the designer:
Analog to Digital Converter: 4 inputs at 8bit resolution.
Pulse Measurement Unit (PMU): 3 modules used to interface to smart analog sensors.
 Event and Waveform Controller (EWC): 5 programmable Counters e.g. for Pulse Width Modulation (PWM) or Compare/Capture functions.
