PIC18 Q84 family transmits-receives data through CAN FD

Microchip believes the PIC18 Q84 family is the first PIC18 microcontroller that can transmit and receive data through a controller area network flexible data rate (CAN FD) bus.

It meets the demand for increased bandwidth and flexible data rates in evolving automotive applications like safety and communication. It also supports the development of advanced driver assistance systems (ADAS), adds Microchip Technology.

Used with an array of core independent peripherals (CIPs) that handle a variety of tasks without requiring CPU intervention, the PIC18 Q84 family reduces time and cost when connecting systems to a CAN FD network.

The microcontrollers transport sensor data to a CAN FD bus without the need for gateways or sophisticated network switching techniques. Its configurable CIPs allow users to create custom hardware-based functions for automotive and industrial designs with near-zero latency, without requiring additional code. Peripherals include a 32-bit cyclic redundancy check with scan (CRC/Scan), a windowed watchdog timer (WWDT) for functional safety capabilities, and a Joint Test Action Group (JTAG) interface to implement industry standard testing and debugging.

“CAN FD will continue to play a critical role in delivering faster data transfer rates for applications, ranging from the connected car to industrial automation and smart homes,” said Greg Robinson, associate vice president of marketing for Microchip’s 8-bit microcontroller business unit. The additon of the 8-bit PIC microcontroller family is expected to advance the adoption of the CAN FD protocol, helping designers create cost-effective network nodes at scale, he added.

The PIC18 Q84 family offers both hardware and software support. Hardware includes a Curiosity nano development board and a Curiosity high pin count (HPC) development board. A plug-in module (PIM) is also available for the automotive networking development board and for use with Microchip development boards. Software includes Microchip’s MPLAB Code Configurator (MCC).

Microchip also provides a broad family of CAN FD transceivers and CAN FD controllers.

The PIC18 Q84 family is available in volume production now.
