rfPIC12C509AG/509AF
High-Performance RISC CPU:
• Only 33 single word instructions to learn
• All instructions are single cycle (1
µs) except for
program branches which are two-cycle
• Operating speed: DC - 4 MHz clock input
DC - 1
µs instruction cycle
• 12-bit wide instructions
• 8-bit wide data path
• Seven special function hardware registers
• Two-level deep hardware stack
• Direct, indirect and relative addressing modes for
data and instructions
• Internal 4 MHz RC oscillator with programmable
calibration (independent from transmitter quartz
crystal reference)
• In-Circuit Serial Programming™ (ICSP™)
Peripheral Features:
• 8-bit real time clock/counter (TMR0) with 8-bit
programmable prescaler
• Power-On Reset (POR)
• Device Reset Timer (DRT)
• Watchdog Timer (WDT) with its own on-chip RC
oscillator for reliable operation
• Programmable code-protection
• Power saving SLEEP mode
• Wake-up from SLEEP on pin change
• Internal weak pull-ups on I/O pins
• Internal pull-up on MCLR pin
• Selectable oscillator options:
- INTRC: Internal 4 MHz RC oscillator
- EXTRC: External low-cost RC oscillator
- XT:
Standard crystal/resonator
- LP:
Power saving, low frequency crystal
Pin Diagram
UHF ASK/FSK Transmitter:
• Conforms to US FCC Part 15.231 regulations and
European ERC 70-03E and EN 300 220-1
requirements
• VCO phase locked to quartz crystal reference;
allows narrow band receivers to be used to maxi-
mize range and interference immunity
• Integrated crystal oscillator and VCO requiring
minimum of external components
• Crystal frequency divide by 4 available (CLKOUT)
• Frequency range set by crystal: 310 – 480 MHz
• ASK Data rate: 0 –40Kbps
• FSK through crystal pulling allows modulation at
0–20Kbps
• Adjustable output power: +2 dBm to -12 dBm in
six discrete steps
• Differential output configurable for single or
double ended loop antenna
• Power amplifier automatically disabled until after
PLL lock
