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
four 16-bit counter/timers (see description in
in
Special Function Register (SFR) address space
tion
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 9.1 for a block diagram).
The CIP-51 includes the following features:
Section
- Fully Compatible with MCS-51 Instruction
- 0 to 48 MHz Clock Frequency
- 256 Bytes of Internal RAM
- 25 Port I/O
