Microchip releases system basis chips

It comes amid an increase in connected applications in the automotive and industrial markets, which in turn is driving demand for wired connectivity solutions with higher bandwidth, lower latency and enhanced security.

The ATA650x CAN FD SBCs offer a small 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 show very low power consumption, with a typical sleep current of just 15μA. The ATA650x SBCs enable control of the V_CC supply voltage by the bus signals, which reduces the current consumption of automotive Electronic Control Units (ECUs). To further reduce power consumption, the SBCs can disable the microcontroller supply by switching off LDOs during sleep mode.

The safety features available in the ATA650x device include fail safe, protection and diagnostic functions to provide reliable bus communication in advanced networks. Designed to withstand Electrostatic Discharge (ESD)and equipped with Electromagnetic Compatibility (EMC) performance, the ATA650x devices are robust solutions for applications that are operating in harsh environments.

“Our compact CAN FD SBC is engineered for space-constrained applications, specifically addressing the critical need for resilience in demanding environments,” commented 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.”
