ZETAPLUS-915-D RF Solutions

ZETAPLUS Miniature Smart RF Transceiver Features Intelligent Wire replacement SMARTRADIO form factor: 16mm x 18mm 2Km range Transmit Power +13dBm High sensitivity -116dBm ( 2.4kbps) Max data rate 500Kbps Simple UART and SPI interface Full CRC Error Checking Option User Selectable Data Payload Best in Class cost performance Available as 433/868/915MHz 1.8V 3.6V Operating Voltage Low power consumption - 0.5nA Standby Applications Home automation - 10mA Rx Sensor / mesh RF networks - 18mA Tx 10dBm Telemetry 64 byte Buffer (FIFO) Keyless entry Integrated battery voltage sensor Health monitors Based on Silicon Labs Si4455 chipset RF Data comms No configuration necessary No external components Applications ZETAPLUS makes a radio data link easy. It has a simple interface using either SPI or UART (LV RS232) and provides a plug n play RF comms to any application. With connection to power, comms and antenna, the user can start sending and receiving data immediately. No other external components are required. With a highly tuned on-board RF matching network ZETAPLUS outperforms other modules achieving range far in excess of its competitors for the given power output/power con- sumption.

Shutdown state is the lowest current consumption of the device. Settings will be retained when SDN is asserted. When shutdown is activated no comms are possible as the device is in deep sleep mode. The time between taking the 3 SDN Shutdown In shutdown pin low and a command being excepted varies de- pending on supply, crystal etc and can range from 10-25ms. ZETAPLUS is ready for commands when the nIRQ pin goes high. There can be up to 2ms after the shutdown pin has gone low where the nIRQ pin is in an unknown state so al- ways give 2ms after lowering the shutdown pin 4 Vcc V Supply In Supply Voltage Connection Active Low 5 nIRQ Interrupt Output Data packet received in SPI RX mode only UART 6 UART TX Out UART (LV RS232) Data appears on this output Transmit Gen Pur- In / 7 GPIO1 This is not yet implemented pose I/O Out UART 8 UART RX In RS232 Receive Pin Receive 9 SCLK Serial clock In SPI Clock In Serial data 10 SDI In SPI Data In In Serial data 11 SDO Out SPI Data Out Out SPI Device Select (Active Low) Serial inter- 12 nSEL In Only used in SPI mode is SPI not used pull high or leave dis- face select connected Page 2 DS-ZETAPLUS-6
