P89LPC930 特性

  • high performance 80C51 CPU provides instruction cycle times of 111 ns to 222 ns for all instructions except multiply and divide when executing at 18 MHz. This is 6 times the performance of the standard 80C51 running at the same clock frequency. A lower clock frequency for the same performance results in power savings and reduced EMI.
  • 2.4 V to 3.6 V VDD operating range. I/O pins are 5 V tolerant (may be pulled up or driven to 5.5 V).
  • 4 kB/8 kB Flash code memory with 1 kB sectors, and 64-byte page size.
  • Byte-erase allowing code memory to be used for data storage.
  • Flash program operation completes in 2 ms.
  • Flash erase operation completes in 2 ms.
  • 256-byte RAM data memory.
  • Two 16-bit counter/timers. Each timer may be configured to toggle a port output upon timer overflow or to become a PWM output.
  • Real-Time clock that can also be used as a system timer.
  • Two analog comparators with selectable inputs and reference source.
  • 400 kHz byte-wide I2C-bus communication port.
  • SPI communication port.
