As connected applications in the automotive and industrial markets continue to grow, the demand for wired connectivity solutions with higher bandwidth, lower latency, and enhanced security is increasing. Reliable and secure communications networking solutions are essential to accurately transmit and process data.

Microchip Technology Inc. today announced the new ATA650x CAN FD System Basis Chip (SBC) family.

The chip fully integrates a high-speed CAN FD transceiver and a 5V low-voltage regulator (LDO) and is available in space-saving small packages of 8-pin, 10-pin, and 14-pin.

The ATA650x CAN FD SBC family offers very small package sizes, including the 2 mm × 3 mm VDFN8 package, the 3 mm × 3 mm VDFN10 package, and the 3 mm × 4.5 mm VDFN14 package. The chip also features a built-in high-speed CAN FD transceiver, supporting data transmission and reception speeds of up to 5 Mbps per second.

This family of SBCs is a powerful solution for space- and power-constrained applications, featuring very low power consumption, typically consuming only 15 μA in sleep mode.

The ATA650x SBC family can control the VCC supply voltage through bus signals, which can reduce the current consumption of automotive electronic control units (ECUs). The SBC family can further reduce power consumption by turning off the LDO during sleep mode, thereby cutting off power to the microcontroller.

The ATA650x devices include failsafe features and protection and diagnostics to provide reliable bus communications in advanced networks. Additionally, the devices are designed to withstand electrostatic discharge (ESD) and have electromagnetic compatibility (EMC) performance, making them suitable for applications that require reliable operation in harsh environments.

Integrated SBC solutions support functional safety to help achieve ISO 26262 safety certification or the desired ASIL level. Additionally, this SBC is AEC-Q100 qualified, Grade 0 and is designed to operate over a temperature range of -40°C to +150°C.

“Microchip’s compact CAN FD SBCs are designed for space-constrained applications while delivering the resiliency needed to meet demanding environments,” said Rudy Jaramillo, vice president of Microchip’s Analog Power and Interface business unit. “This highly integrated solution helps reduce system cost by saving board space and provides an easier design-in experience for customers.”

Meanwhile, the ATA650x CAN FD SBCs are part of Microchip’s broad portfolio of connectivity solutions, which also includes system-in-package (SiP) solutions that integrate standard LIN and CAN transceivers with a microcontroller.
