The SI80MC51 is an Intel microcontroller
compatible, which is a true computer on chip. The product incorporates all of the features found in a microprocessor CPU: ALU, Program Counter, Stack Pointer and Registers. It also has added the other features needed to make a complete computer: ROM, RAM, parallel I/O, serial I/O, counters, and a clock circuit....view full
The R8051XC-A 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 R8051XC-A version
provides software and hardware interrupts, an interface for
serial communications and two timers.
The R8051XC-A is a microcode-free design developed for
reuse in ASIC and FPGA implementations. The design is
strictly synchronous with positive-edge clocking, no internal
tri-states and a synchronous reset; therefore scan insertion is
straightforward....view full
