RF Solutions has unveiled a new family of radio transceivers taking advantage of advanced silicon integration to deliver unprecedented data rates and communication range among board-mount modules for cost-sensitive cable replacement, remote control, switching, tracking, monitoring, security, metering, and data-logging applications. The ZULU family offers designers a choice of firmware specifications for control or data collection, or a basic transceiver ready for custom firmware. The modules combine an 8051-based microcontroller with a sub-GHz RF transceiver operating with FSK, GFSK, or OOK modulation in the license-free 433, 868, or 915 MHz frequency bands. Modules are available in surface-mount or dual-inline options. Telemetry firmware in the ZULU-T modules allows designers to build a multi-channel remote industrial switching application in which the receiver outputs follow the transmitter inputs. These modules are ideal for remote control, networking or switching applications requiring control of up to 10 digital channels and two PWM channels over a range of up to 2 km. The ZULU-M transceiver is a radio modem capable of supporting RF data rates of up to 56 kbps over eight user-selectable channels. The module provides a simple modem interface to the system host controller, and handles all RF communications such as packetising, preamble, encoding, and CRC checking without user intervention. RF transmit power of +20 dBm and receive sensitivity of -121dBm ensures reliable, high-speed communications up to distances of up to 2 km. For customers using proprietary wireless firmware or requiring custom functionality, the base ZULU transceiver provides rich analogue and digital peripherals such as a 10-bit ADC, dual comparators, SmaRTClock, plus UART, SPI, and I2C ports. The module has a 25-MHz 8051 microcontroller and up to 64 kB of on-board Flash. By using the latest generation, highly integrated wireless transceiver ICs, the ZULU modules offer competitive pricing, low power consumption and operating voltages, and the advantages of simplified system integration with minimal additional components required. To accelerate development of wireless control and monitoring applications using the ZULU family, RF Solutions has also released ZULUEVAL-T and ZULUEVAL-M evaluation kits. The ZULUEVAL-T kit comprises a pair transmit and receive boards containing the ZULU-T telemetry module, which are easily paired and use either RS-232 or USB host communications. The ZULUEVAL-M kit also features RS-232 or USB connection, and provides transmit/receive indicator LEDs. Both kits operate from a 12-V DC supply. RF Solutions
