2.4 GHz 802.15.4 Wireless Transceiver

The exchange of data between several devices is commonplace nowadays. It comes to no surprise then that standards for these types of communications have come up over the years, and have become an important part in Personal Area Networks. So, if you are looking into a project that needs 802.15.4 compatibility, the MCR20A is just what you need.

The MCR20A expands the NXP portfolio of wireless connectivity products by delivering a new generation of 2.4 GHz transceiver for the IEEE® 802.15.4 standard. The MCR20A provides a world-class link budget of 110 dB that ensures the longest range of communication. At the same time, the MCR20A is able to receive and transmit at significantly lower peak currents than other competitive devices. This enables mesh networks to run on the same battery for a much longer period. The Dual PAN support allows the system to concurrently participate in two 802.15.4 networks, eliminating the need for multiple radios.

1.8 V Simple Mobile Interface Link Bridge IC

The PTN3700 is a 1.8 V simple mobile interface link bridge IC which can function both as a transmitter-serializer or a receiver-deserializer for RGB888 video data. It comes with 3 differential subLVDS high speed serial lanes and one pixel clock. The serial interface link of the PTN3700 is based on the open Simple Mobile Interface Link (SMILi) definition.

The PTN3700 has is designed to be able to maintain a low power profile and can operate in three power modes. Shutdown mode for minimum idle power (< 3 uA typical). Low-power Standby mode with input clock frequency auto-detect (< 3 A typical). Low active transmitter power: 18 mW (typ.) for QVGA1 and 40 mW (typ.) for WVGA2. Low active receiver power: 15 mW (typ.) for QVGA and 36 mW (typ.) for WVGA.

Multiprotocol IC Card Interface

Smart Cards, or Integrated Circuit Cards, are useful and are a very convinient means of providing personal identification, authentication, data storage, application processing and many other applications. If you are looking for smart card reader that’s cost-effective and compliant to all of the ISO 7816, GSM 11-11, EMV4.2 and EMV 2000 requirements, then the TDA8007BHL might just be what you need.

Control and communication is through an 8-bit parallel interface, compatible with non-multiplexed memory access. It can be also addressed through a multiplexed memory access. Specific ISO UART with parallel access input/output for automatic convention processing, variable baud rate through frequency or division ratio programming, error management at character level for T = 0 and extra guard time register.
