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. Included are three 16-bit counter/timers (see descrip-
tion in
128 byte Special Function Register (SFR) address space
in
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:
