8. CIP-51 Microcontroller
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 soft-
ware. The C8051F52x/F52xA/F53x/F53xA family has a superset of all the peripherals included with a stan-
dard 8051. See Section “1. System Overview” on page 13 for more information about the available
peripherals. The CIP-51 includes on-chip debug hardware which 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 core includes the following features:
