P89LPC915 特性

  • 2 kB byte-erasable Flash code memory organized into 256-byte sectors and 16-byte pages. Single-byte erasing allows any byte(s) to be used as non-volatile data storage.
  • 256-byte RAM data memory.
  • Two 16-bit counter/timers. Timer 0 may be configured to toggle a port output upon timer overflow or to become a PWM output.
  • 23-bit system timer that can also be used as a Real-Time clock.
  • 4-input multiplexed 8-bit A/D converter/single DAC output. Two analog comparators with selectable reference.
  • Enhanced UART with fractional baud rate generator, break detect, framing error detection, automatic address detection and versatile interrupt capabilities.
  • Internal RC oscillator option allows operation without external oscillator components. The RC oscillator (factory calibrated to +- 1 pct.) option is selectable and fine tunable.
  • 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).
