Low voltage long-range ISM transceiver with embedded MCU and ADC

24 March 2004 Telecoms, Datacoms, Wireless, IoT Access Control & Identity Management

Nordic's nRF9E5 and nRF905 components are designed for wireless transceiver applications in industrial as well as domestic environments in the frequency range 430-928 MHz. Typical uses include security systems, wireless data transfer, automatic meter reading, car alarm systems, point-of-sale systems, sensors and various telemetry systems. Manufactured in modern 0,18 µm CMOS process, the entire transceiver includes all inductors and filters integrated in a single chip.

The nRF9E5 transceiver has an embedded 8051 compatible MCU, and four input 10 bit ADC - providing the market with a complete low cost wireless system-on-a-chip solution with a single 1,9 V-3,6 V supply. Voltage regulators are embedded on-chip to further lower the system cost, and to enhance performance.

Both components include the company's unique ShockBurst feature that is used in both receive and transmit mode and simplifies software and protocol design. ShockBurst includes features for CRC computation in both TX and RX mode, and address decoding in RX mode, reducing the load and cost of the MCU running the RF protocol. It is capable of buffering up to 32 bytes of payload coupled with short start-up times, which enables very low power duty cycled systems.

A crystal and a resistor are the two components needed externally to make up a complete system around the nRF905. The nRF9E5 requires an external EEPROM for external program storage. Both the components are delivered in lead-free 32 pin 5 x 5 mm QFN package.

A unique feature of the nRF9X5 family is the capability to operate with the same layout and identical external components in the unlicensed European 868 MHz ISM band as well as the North American 915 MHz SRD band, easing logistics for manufacturers who have customers in both territories.
