    关于rfPIC12C509AF
    The rfPIC12C509AF from Microchip Technology is a low-cost, high performance, 8-bit, fully static,EPROM-based CMOS microcontroller combined with a UHF ASK/FSK transmitter. It employs a RISC architecture with only 33 single word/single cycle instructions. All instructions are single cycle (1 ms) except for program branches which take two cycles. The 12-bit wide instructions are highly symmetrical resulting in 2:1 code compression over other 8-bit microcontrollers in its class. The easy to use and easy to remember instruction set reduces development time significantly.
  The rfPIC12C509AF product is equipped with special features that reduce system cost and power requirements. The Power-on Reset (POR) and Device Reset Timer (DRT) eliminate the need for external RESET circuitry. There are four oscillator configurations to choose from, including INTRC internal oscillator mode and the power-saving LP (Low Power) oscillator mode. Power saving SLEEP mode, Watchdog Timer and code protection features also improve system cost, power and reliability.
  The Transmitter is a fully integrated UHF ASK/FSK transmitter consisting of crystal oscillator, phaselocked loop (PLL), open-collector differential-output Power Amplifier (PA), and mode control logic. External components consist of bypass capacitors, crystal, and PLL loop filter. There are no internal electrical connections between the PICmicro MCU and the transmitter.The PICmicro MCU oscillator is independent from the transmitter crystal oscillator.
  The rfPIC12C509AF is capable of ASK or Frequency Shift Keying (FSK) modulation by employing an internal FSK switch to pull the transmitter crystal via a second load capacitor.
  The rfPIC12C509AF is a single channel device.The transmit frequency is fixed and set by an external reference crystal. Transmit frequencies in the range of 310 to 480 MHz can be selected. Output drive is an open-collector differential amplifier. The differential output is well suited for loop antennas. Output power is adjustable from +2 dBm to -12 dBm in six discrete steps.
