Compact CAN FD system basis chip solution for space-constrained applications

Microchip Technology has announced the new family of ATA650x CAN FD System Basis Chips (SBCs), which include a fully integrated high-speed CAN FD transceiver and a 5V LDO in compact 8, 10 and 14-pin space-saving packages.

The SBCs provide a tiny footprint of 2mm × 3mm for the VDFN8 package, 3mm × 3mm for the VDFN10 package and 3mm × 4.5mm for the VDFN14 package. With a built-in high-speed CAN FD transceiver, the SBCs support data transmit and receive rates of up to 5Mbps.

A robust solution for space and power-constrained applications, these SBCs exhibit low power consumption, with a typical sleep current of just 15μA. The SBCs enable control of the VCC supply voltage by the bus signals, which decreases the current consumption of automotive ECUs. To further lower power consumption, the SBCs can disable the MCU supply by switching off LDOs during sleep mode.

The device's safety features include failsafe, protection, and diagnostic functions to provide reliable bus communication in advanced networks. The devices are robust solutions for applications operating in harsh environments, designed to withstand ESD and equipped with EMC performance.

The integrated SBC solution is Functional Safety ready to help customers achieve an ISO 26262 safety certification or the desired ASIL level. Also, the SBCs are AEC-Q100 qualified with a Grade 0 rating and are designed to operate in temperatures ranging from −40C to +150C.

"Our compact CAN FD SBC is engineered for space-constrained applications, specifically addressing the critical need for resilience in demanding environments," said Rudy Jaramillo, vice president of Microchip's analog power and interface division. "This highly integrated solution can aid in system-level cost savings by minimising board space requirements and helping reduce design complexities for our customers."

The ATA650x CAN FD SBCs are part of the company's extensive portfolio of connectivity solutions, which includes standard LIN and CAN transceivers and SiPs with integrated MCUs.
