Part Number : R80515
Overview :
The R80515 is a core of a fast single-chip 8-bit microcontroller. It is a fully functional 8-bit embedded controller that executes all ASM51 instructions and has the same instruction set as the 80C31. The R80515 provides software and hardware interrupts, interfaces for serial communications, timer system with compare-capture-reload resources and, I/O ports, power management unit, and a watchdog timer.
The R8051
Features : - Control Unit
- 8-bit Instruction decoder
- reduced instruction cycle time (up to 12 times in respect to standard 80C51
