10. CIP-51 CPU
The MCUs’ system CPU is the CIP-51. The CIP-51 is fully compatible with the MCS-51
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 four 16-bit counter/timers (see description in Section
19), a full-duplex UART (see description in Section 18), 256 bytes of internal RAM, 128 byte Special Function
Register (SFR) address space (see Section 10.3), 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 21), and interfaces directly with the
MCUs’ analog and digital subsystems 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 10.1 for a block diagram). The CIP-51
includes the following features:
