Popular MCU family solves low-data-rate wireless challenges

The rfPIC™ family from Microchip combines the established advantages of the PIC® microcontrollers with an integrated FSK/ASK transmitter for embedded short-range wireless applications in the unlicensed ISM bands.

Three versions of the rfPIC12F675x controller/transmitter are available for use in the 260-350MHz, 390-450MHz, or 850- 930MHz frequency bands. The maximum data rate is 40kbit/s, and the 100nA stand-by supply current saves overall power consumption. On-chip resources include 1.8kbytes Flash programme memory, 64bytes RAM and 128bytes EEPROM, as well as an analogue comparator and a four-channel 10-bit ADC. Two compatible receivers, the rfRXD0420 and rfRXD0920, allow designers to quickly set up a uni-directional wireless link when building embedded controllers. With low power consumption and a wide operating voltage range, these receivers minimise energy consumption and simplify powersupply design.

 

FEATURES Sub-10mA active supply current Operating voltage: 2.5V to 5.5V Adjustable transmitter power Compatible with narrow-band receivers

APPLICATIONS Remote control Wireless sensors Home security Meter reading and low-power telemetry Automotive alarms and Remote Keyless Entry (RKE)
