At the CAN FD Tech-Day in Shanghai, Infineon launched its CAN transceivers and SBCs (system base chips) supporting bit-rates of 2 and 5 Mbit/s. They will be available in June 2015 respectively in August 2016.
THE TLE7250SJ AND TLE7250VSJ WILL BE QUALIFIED FOR BIT-RATES up to 2 Mbit/s. Engineering samples are available. The TLE9250SJ and TLE9250VSJ will support bit-rates up to 5 Mbit/s. The ISO 11898-2 compliant products come in DSO-8 as well as TSON-8 packages and comply with the hardware specification version 1.3 by German carmakers.
In addition, Infineon plans similar transceivers compliant with ISO 11898-5 providing a low-power functionality. The TLE7251VSJ will support 2 Mbit/s, the TLE9251VSJ 5 Mbit/s. These transceivers feature a maximum short-circuit current of 100 mA. In stand-by (low-power) mode the bus termination is to ground.
CAN transceivers with selective wake-up functionality will also be enabled for data-rates up to 5 Mbit/s (TLE9255WSK). The arbitration bit-rate is limited to 500 kbit/s as specified in ISO 11898-6. They come in a PG-DOS-14 housing. Engineering samples will be available in June 2016.
The German chipmaker also launched some system base chips with CAN transceiver functions. The TSBC family TLE926x is specified for 2 Mbit/s. Additionally, these chips provide two LIN transceivers and voltage regulators for 3,3 V and 5 V. Other features include SPI connectivity and wake-up inputs. The DCDC SBC family TLE927x provides up to four LIN transceivers and low-power as well as fail-safe operating modes. TLE926x and TLE927x devices are all software compatible. Because the CAN FD protocol (ISO 11898-1) and the related high-speed physical media attachment standard (ISO 11898-2) are under development, all information given by Infineon is based on today’s knowledge and expectations.
