S6BT112A CXPI Transceiver

CXPI (Clock eXtension Peripheral Interface) is designed to succeed the widely-used Local Interconnect Network (LIN) automotive communication protocol. CXPI reduces the bill-of-material costs and lower fuel consumption by requiring fewer wire harnesses in a vehicle. Infineon offers CXPI transceivers, as well as automotive MCUs – a complete solution for your automotive design needs.

CXPI has the CSMA/CR system (event initiate system) built into the polling system of LIN, provides higher response time and scalability, and significantly reduces HMI and development costs.

CXPI has reduced the number of the parts needed for the clock side of the design because a data and a clock can transmit at the same time by adoption of PWM. Furthermore, reliability improves by a communication between slaves, a secondary clock master function and a CRC.

The S6BT112A01 and S6BT112A02 are integrated transceiver IC for Automotive communication network with Clock eXtension Peripheral Interface (CXPI). It is flexible bit rate from 2.4 k bit per second to 20 k bit per second with JASO CXPI compliant. This CXPI transceiver IC connect between CXPI data link controller and CXPI Bus line, and enables to connect to vehicle battery directly, with high surge protection. Additionally a product has optional function for Spreads Spectrum Clock Generator (SSCG). In the standby operation, S6BT112A01 and S6BT112A02 success ultra-low power consumption as sleep mode. The Cypress CXPI transceiver IC supports master node and slave node as selected SELMS pin which supported a secondary clock master.

Infineon's CXPI transceivers achieved best-in-class low noise by a generating pseudo sine wave, a smart key band (100 kHz to 160 kHz) noise reduction and SSCG (Spreads Spectrum Clock Generator, Option). It will support to reduce customer’s PCB design effort that is necessary to consider the effect of emission. Also, it will become the advantage especially when a wiring is bundled.

They supported an ESD H.B.M 8 kV and a bus negative break down voltage -40 V, they will support robustness firmly for automotive request.
In addition, Infineon's CXPI transceiver operating voltage range is 5.3 V to 18 V and it has a wide operating range. It will be advantage when a battery voltage falls.
Infineon's CXPI transceiver realized a sleep current 6 uA (typical) @slave and supports a wakeup control function. It will contribute to improvement in the energy efficiency of a vehicle.

Infineon can provide package solution together CXPI transceiver, MCU's and driver software. Also we can provide a software implementation commissioned development services.
