1.1.
1.1.1.
The C8051F000 family utilizes Silicon Laboratories’ proprietary CIP-51 microcontroller core. The CIP-51 is fully
compatible with the MCS-51
develop software.
counter/timers, a full-duplex UART, 256 bytes of internal RAM space, 128 byte Special Function Register (SFR)
address space, and four byte-wide I/O Ports.
1.1.2.
The CIP-51 employs a pipelined architecture that greatly increases its instruction throughput over the standard 8051
architecture. In a standard 8051, all instructions except for MUL and DIV take 12 or 24 system clock cycles to
execute with a maximum system clock of 12-to-24MHz. By contrast, the CIP-51 core executes 70% of its
instructions in one or two system clock cycles, with only four instructions taking more than four system clock
cycles.
The CIP-51 has a total of 109 instructions. The number of instructions versus the system clock cycles to execute
them is as follows:
With the CIP-51’s maximum system clock at 25MHz, it has a peak throughput of 25MIPS. Figure 1.4 shows a
comparison of peak throughputs of various 8-bit microcontroller cores with their maximum system clocks.
