CIP-51 Microcontroller
General Description
The MCU’s system controller core is the CIP-51 microcontroller. The CIP-51 is fully compatible with the
MCS-51
TM
instruction set. Standard 803x/805x assemblers and compilers can be used to develop soft-
ware. The MCU has a superset of all the peripherals included with a standard 8051. Included are three
16-bit counter/timers (see description in Section 17), a full-duplex UART (see description in Section 16),
256 bytes of internal RAM, 128 byte Special Function Register (SFR) address space (see Section 9.3),
and four byte-wide I/O Ports (see description in Section 14). The CIP-51 also includes on-chip debug
hardware (see description in Section 18), and interfaces directly with the MCU’s analog and digital sub-
systems providing a complete data acquisition or control-system solution in a single integrated circuit.
Features
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 9.1 for a block diagram).
The CIP-51 includes the following features:
