P89LPC901 特性

  • 1 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.
  • 128-byte RAM data memory.
  • Two 16-bit counter/timers. (P89LPC901 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.
  • Single analog comparators
  • High-accuracy 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 with 5 V tolerant I/O pins (may be pulled up or driven to 5.5 V). Industry-standard pinout with VDD, VSS, and reset at locations 1, 8, and 4.
  • Up to six I/O pins when using internal oscillator and reset options.
  • 8-pin SO-8 package.
