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 MCU family has a superset of all the peripherals included with a standard 8051. Included are
three 16-bit counter/timers (see description in Section 15), an enhanced full-duplex UART (see description
in Section 14), 256 bytes of internal RAM, 128 byte Special Function Register (SFR) address space (Sec-
tion 8.2.6), and one byte-wide I/O Port (see description in Section 12). The CIP-51 also includes on-chip
debug hardware (see description in Section 17), and interfaces directly with the analog and digital subsys-
tems 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:
