300-100 MHz integrated RF transceiver and microcontroller

23 October 2002 Telecoms, Datacoms, Wireless, IoT

Chipcon has released what it says is the industry's first single-chip 300-1000 MHz CMOS RF transceiver and microcontroller IC. Chipcon has integrated its CMOS CC1000 RF transceiver on a single die with an industry standard 8051 microcontroller core including on-chip flash non-volatile memory.

The CC1010 is designed primarily for FSK systems in the 315, 433, 868 and 915 MHz ISM/SRD bands, but can be programmed for operation at other frequencies between 300 and 1000 MHz. It is based on the same proprietary SmartRF 02 technology as the CC1000 RF transceiver.

Key features of the transceiver are: very low current consumption, high sensitivity (typically -107 dBm), programmable output power up to 10 dBm, FSK modulation with a data rate up to 76,8 Kbps, programmable carrier frequency, bit-synchronisation, and a RSSI output that can be sampled by the on-chip ADC.

The CC1010 on-chip microcontroller is compatible with the industry standard Intel 8051 controller but with approximately 2,5 times improved speed. Data memory for the controller is provided on-chip via two blocks of SRAM (128 byte and 2 kB). CC1010 has 32 KB of on-chip, in-system, self-programmable, nonvolatile flash program memory. Additional features include a three-channel 10-bit analog to digital converter (ADC), realtime clock (RTC) with its own 32 kHz crystal oscillator, programmable watchdog time (WDT), two 8051 timers and two timers/PWM, two programmable serial UARTs, master SPI interface and 26 configurable general I/O-pins.

The supply voltage of CC1010 is 2,7 to 3,6 V and the chip is provided with on-chip power-on-reset (POR) and brown-out circuitry. It is supported by comprehensive development tools. In-circuit interactive debugging is supported for the Keil µ Vision IDE through a simple serial interface. A large code library and many application examples are provided. Powered by the SmartRF Studio Software for easy RF testing, the development kit helps shorten development time. CC1010 comes in TQFP 64 package.
