Description

The TN100 transceiver is a highly integrated mixed signal chip that uses the wireless

communication technology CSS (chirp spread spectrum) developed by Nanotron

Technologies.

With its unique ranging capability, TN100 can measure the link distance between two nodes.

Thus, TN100 supports location awareness applications including location based services

(LBS) and asset tracking (2D/3D RTLS). Ranging is performed during regular data

communication and does not require additional infrastructure, power, and/or bandwidth. For

an even better ranging accuracy, a high precision mode is provided. SDS-TWR algorithm

(symmetrical double-sided two-way ranging) allows superior accuracy even with the use of

low cost crystals for the oscillators.

The TN100 transceiver IC is designed to build up robust, short distance wireless networks

operating in the 2.45 GHz ISM band with extremely low power consumption over a wide

range of operating temperatures.

The TN100 supports 7-frequency channels with 3 non-overlapping channels. This provides

support for multiple physically independent networks and improved coexistence

performance with existing 2.4 GHz wireless technologies. Data rates are selectable between

31.25 kbps and 2 Mbps. Due to the chip's unique chirp pulse, adjustment of the antenna is

not critical. This significantly simplifies the system's installation and maintenance ("pick-and-

place").

The TN100 transceiver includes a sophisticated MAC controller with CSMA/CA and TDMA

support as well as forward error correction (FEC) and 128-bit hardware encryption. It also

provides scrambling, automatic address matching, and packet retransmission, thus

minimizing the requirements for microcontroller and software.

Through its high-speed standard SPI interface, the TN100 can be interfaced with a wide

range of external micro-controllers. It includes a 4 kbits frame buffer which allows even very

slow microcontrollers to work with the transceiver. This means that several receive and

transmit frames can be stored simultaneously in the buffers. This solution eliminates the

problems of different peak data rates between air and microcontroller interfaces.

Target applications for the TN100 include:

●

Asset tracking

●
