8.
The MCU system controller core is the CIP-51 microcontroller. The CIP-51 is fully compatible with the
MCS-51™ instruction set; standard 803x/805x assemblers and compilers can be used to develop
software. The MCU family has a superset of all the peripherals included with a standard 8051. The CIP-51
also includes on-chip debug hardware (see description in Section 27), and interfaces directly with the
analog and digital subsystems providing a complete data acquisition or control-system solution in a single
integrated circuit.
The CIP-51 Microcontroller core implements the standard 8051 organization and peripherals as well as
additional custom peripherals and functions to extend its capability (see Figure 8.1 for a block diagram).
The CIP-51 includes the following features:
8.1.
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, and usually have a maximum system clock of 12 MHz. By contrast, the
CIP-51 core executes 70% of its instructions in one or two system clock cycles, with no instructions taking
more than eight system clock cycles.
