The XC87x is based on a high-performance 8-bit Central Processing Unit (CPU) that is compatible with the standard 8051 processor. While the standard 8051 processor is designed around a 12-clock machine cycle, the XC87x CPU uses a 2-clock machine cycle. This allows fast access to ROM or RAM memories without wait state. The instruction set consists of 45% one-byte, 41% two-byte and 14% three-byte instructions. The XC87x CPU provides a range of debugging features, including basic stop/start, single-step execution, breakpoint support and read/write access to the data memory, program memory and Special Function Registers (SFRs).
