KNX transceiver twisted pair networks (KNX TP1-256) can use NCN5121 as a reciever-transmitter Integrated Circuit (IC). NCN5121 embeds both PHY and MAC layers and handles the transmission and reception of data on the bus. It generates from the unregulated bus voltage stabilized voltages for its own power needs as well as to power external devices. NCN5121 assures safe coupling to and decoupling from the bus. Various monitors (bus voltage, current, temperature...) are made available through an analog pin.

The NCN5150 is a single-chip integrated slave transceiver for use in two-wire Meter Bus (M-BUS) slave devices and repeaters. The transceiver provides all of the functions needed to satisfy the European Standards EN 13757-2 and EN 1434-3 describing the physical layer requirements for M-BUS. It includes a programmable power level of up to 2 (SOIC version) or 6 (NQFP version) unit loads which are available for use in external circuits through a 3.3V LDO regulator.The NCN5150 can provide communication up to the maximum M-BUS communication speed of 38400 baud (half-duplex).

The NCN5151 is a single-chip integrated slave transceiver for use in 2-wire Meter Bus (M-BUS) slave devices and repeaters. The NCN5151 reuses the NCN5150 features and adds two lowpower modes: a 2-wire low power mode dedicated to System for meter Communication and Readout for powerless meters (SCR) and a 3-wire low power mode allowing support for wireless applications. When configured in low power mode, the transceiver will not behave anymore as a constant current source in order to save energy. When configured and used in M-BUS mode, the NCN5151 transceiver provides all of the functions needed to satisfy the European Standards EN 13757-2 and EN 1434-3 describing the physical layer requirements for M-BUS. It includes a programmable power level of up to 6 unit loads, which are available for use in external circuits through a 3.3 V LDO regulator.

The NCN5193 is a single-chip, CMOS modem for use in highway addressable remote transducer (HART) field instruments and masters. The modem and a few external passive components provide all of the functions needed to satisfy HART physical layer requirements including modulation, demodulation, receive filtering, carrier detect, and transmit-signal shaping. In addition, the NCN5193 also has an integrated DAC for low-BOM current loop slave transmitter implementation.The NCN5193 uses phase continuous frequency shift keying (FSK) at 1200 bits per second. To conserve power the receive circuits are disabled during transmit operations and vice versa. This provides the half-duplex operation used in HART communcations.

The NCN6000 is an integrated circuit dedicated to the smart card interface applications. The device handles any type of smart card through a simple and flexible microcontroller interface. On top of that, thanks to the builtin chip select pin, several couplers can be connected in parallel. The device is particularly suited for low cost, low power applications, with high extended battery life coming from extremely low quiescent current.

The NCN6004A is an interface IC dedicated for Secured Access Module reader/writer applications. It allows the management of two external ISO/EMV cards thanks to a simple and flexible micro controller interface. Several NCN6004A interfaces can share a single data bus, assuming the external MPU provides the right Chip Select signals to identify each IC connected on the bus. A built in accurate protection system guarantees timely and controlled shutdown in the case of external error conditions.On top of that, the NCN6004A can independently handle the power supply , in the range 2.7V to 5.0 volt input voltage, provided to each external Smart Card. The interface monitors the current flowing into each Smart Card, a flag being set in the case of overload.

The NCN6010 is a level shifter analog circuit designed to translate the voltages between a SIM Card and an external microcontroller. A built-in DC/DC converter makes the NCN6010 useable to drive any type of SIM card. The device fulfills the GSM 11.11 specification. The external MPU has an access to a dedicated input STOP pin, providing a way to switch off the power applied to the SIM card in case of failure or when the card is removed.
