* Four capture/compare units to generate pulse width modulated signals
* Special Function Register (SFR) interface, serving up to 50 SFR devices

This 8-bit microcontroller is software compatible with the millions of devices that have been produced since Intel® introduced the 8051 line in 1980.  The TSCR8051 executes all ASM51 instructions and uses the same instruction set as the 8031.  Its Reduced Instruction Set Computer (RISC) core executes many of its instructions in a single clock cycle, providing a significant speed advantage over traditional 8051 devices that execute one instruction every twelve clock cycles.  With clock speeds of up to 200 MHz, these devices are 8051 performance leaders.

The TSCR8051 features extended 32-bit capabilities including an IEEE 754-compliant floating-point coprocessor with comparator, a multiply/divide unit, a population counter, and a leading-zero counter.
