10. CIP-51™ Microcontroller Core

    1. Fully 8051 Compatible

        The C8051F330/1, C8051F330D family utilizes Silicon Labs' proprietary CIP-51 microcontroller core. The CIP-51 is fully compatible with the MCS-51™ instruction set; standard 803x/805x assemblers and compil-ers can be used to develop software. The CIP-51 core offers all the peripherals included with a standard 8052, including four 16-bit counter/timers, a full-duplex UART with extended baud rate configuration, an enhanced SPI port, 768 bytes of internal RAM, 128 byte Special Function Register (SFR) address space, and 17 I/O pins.

    2. Improved Throughput

        The CIP-51 employs a pipelined architecture that greatly increases its instruction throughput over the stan-dard 8051 architecture. In a standard 8051, all instruct ions except for MUL and DIV take 12 or 24 system clock cycles to execute with a maximum system clock of 12-to-24 MHz. By contrast, the CIP-51 core exe-cutes 70% of its instructions in one or two system clock cycles, with only four instructions taking more than four system clock cycles. The  CIP-51  has  a  total  of  109  instructions.  The  table  below  shows  the  total  number  of  instructions  that require each execution time.

11. Additional Features

The C8051F330/1, C8051F330D SoC family includes several key enhancements to the CIP-51 core and peripherals to improve performance and ease of use in end applications. The extended interrupt handler provides 14 interrupt sources into the CIP-51 (as opposed to 7 for the stan-dard 8051), allowing numerous analog and digital peripherals to interrupt the controller. An interrupt driven system requires less intervention by the MCU, giving  it more effective throughput. The extra interrupt sources are very useful when building multi-tasking, real-time systems.Eight reset sources are available: power-on reset circuitry (POR), an on-chip VDD monitor (forces reset when power supply voltage drops below VRST as given in Table 10.1 on page 94), a Watchdog Timer, a Missing Clock Detector, a voltage level detection from Comparator0, a forced software reset, an external reset pin, and an illegal Flash access protection circuit. Each reset source except for the POR, Reset Input Pin, or Flash error may be disabled by the user in software. The WDT may be permanently enabled in soft-ware after a power-on reset during MCU initialization.The internal oscillator factory calibrated to 24.5 MHz ±2%. This internal oscillator period may be user pro-grammed in ~0.5% increments. An additional low-frequency oscillator is also available which  facilitates low-power operation. An external oscillator drive circuit is included, allowing an external crystal, ceramic resonator, capacitor, RC, or CMOS clock source to generate the system clock. If desired, the system clock source may be switched on-the-fly between both internal and external oscillator circuits. An external oscil-lator can also be extremely useful in low power applications, allowing the MCU to run from a slow (power saving) source, while periodically switching to the fast (up to 25 MHz) internal oscillator as needed
