TSCR8051

Draft TSCR8051 8051 RISC Microcontroller High-Speed, 8051-Compatible, With SRAM and Extended Functions 1. Description The TSCR8051 8-bit microcontroller is software compatible with the millions of devices that have been produced since Intel® introduced the 8051 line in 1980. It 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 an instruction every twelve clock cycles. With clock speeds of up to 200 MHz, this device is an 8051 performance leader. The TSCR8051 features 128KBKBytes of partitionable Data and Program memory and 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. 2. Features ƒ Industry standard 8051 / 8031 software compatible ƒ RISC architecture with up to x12 speed advantage / MHz over traditional 8051 family devices ƒ Four speed grades: 100, 150, 180, and 200 MHz ƒ 128KB of additional high-speed SRAM memory ƒ IEEE 754-compliant floating point coprocessor for full arithmetic capabilities – up to 100 MFlops ƒ Extended 32-bit computing functions including population counter, leading zero counter, and floating-point comparator ƒ Dual data pointers for fast data block moves ƒ Full 8051-compatible architecture including: o F...
