Radio Modules & Chipsets
* AM, FM, FM Narrowband Radio Modules
* Transmitters, Receivers & Transceivers
* Encryption chipsets
* Evaluation Kits

|
Many applications have a need for a bidirectional data transfer or an acknowledge back to the transmitter.
Transceivers can also enlarge the active radius of a wireless system in buildings or outside by repeating the communication where the operating distance is not enough with an unidirectional system due to difficult topographic circumstances.
Bidirectional radio system are more reliable and comfortable than unidirectional ones because they have an access control, an automatic frequency selection, a low-current mode (depends on distance) etc.

The Wi.M868T-R™ 868-870MHz transmitter module is a microcontroller-less version of our popular Wi.232DTS-R™ and Wi.232FHSS-25-R™ modules. It offers the same excellent RF performance, yet allows the design engineer to control the radio at the physical level using any microcontroller.
The module is footprint compatible with the many of the Wi.232 family of radios, including the 900MHz Wi.232DTS-R, Wi.232FHSS-25-R, Wi.M900X-R, and the European 868MHz Wi.232EUR-R, and Wi.M868X-R. The Wi.M868T-R supports wide-band mode, where the channel width is 600kHz and also a narrow-band mode where the channel width is 200kHz.The module is configured via a simple SPI style serial interface. Data is transmitted and received using a separate digital serial interface that includes pre-amble and start-of-packet detection.
Maximum transmit power is +15dBm. Maximum receive sensitivity is -112dBm. The transmitter draws 62mA typical at +15dBm. The module has 32 wideband and 84 narrowband channels available.
A footprint compatible module companion version is available in 902-928 MHz for the North American market Wi.M900T-R.
A typical circuit consists of a low-cost microcontroller, a power source, a Wi.M868T-R module, and an antenna. The RK-Wi.M868X development kit is available to support evaluation of this product with separate Wi.M868X-EVM-R evaluation modules for additional wireless node development. The Wi.M868X-R is very similar to the Wi.M868T-R except the Wi.M868T-R is configured as a uni-directional transmitter only device where the Wi.M868X-R is a bi-directional transceiver module. For production, order the Wi.M868T-R.

The AS8202NF communication controller is an integrated device supporting serial communication according to the TTP specification version 1.1. It performs all communication tasks such as reception and transmission of messages in a TTP cluster without interaction of the host CPU. TTP provides mechanisms that allow the deployment in high-dependability distributed real-time systems. It provides the following services:
Predictable transmission of messages with minimal jitters
Fault-tolerant distributed clock synchronization
Consistent membership service with small delay
Masking of single faults
The CNI (communication network interface) forms a temporal firewall. It decouples the Controller network from the host subsystem by use of a dual ported RAM (CNI). This prevents the propagation of control errors. The interface to the host CPU is implemented as a 16-bit wide non-multiplexed asynchronous bus interface. TTP follows a conflict-free media access strategy called time division multiple access (TDMA). This means, TTP deploys a time slot technique based on a global time that is permanently synchronised. Each node is assigned a time slot in which it is allowed to perform transmit operation.
