New Microchip PIC18-Q84: 8-bit MCU for CAN FD Networks

Source: Microchip

Introducing the new Microchip PIC18-Q84 family; these are the first PIC18 microcontroller (MCU) products that can be used to transmit and receive data through a Controller Area Network Flexible Data-Rate (CAN FD) bus. There is a broad range of Core Independent Peripherals (CIPs) that can handle different tasks without requiring CPU intervention, which means reduced time and cost when connecting systems to a CAN FD network.

Designed to meet the demand for increased bandwidth and flexible data rates in progressive Automotive applications, such as safety and communications, the Microchip PIC18-Q84 family can also support the development of advanced driver-assistance systems (ADAS).

The Microchip PIC18-Q84 family provides a simple solution for transporting sensor data to a CAN FD bus by eliminating the need for gateways or other network switching techniques. Configurable CIPs make it easy to create custom hardware-based functions with near-zero latency, and additional code is not required.

Ideal for applications that require faster data transfer rates such as the ‘Connected Car’, Industrial Automation, Smart Homes etc.

Development Tools and CAN FD Product Support

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. Speak to one of our team to find out more about Microchip’s complete CAN and CAN FD offerings.

Microchip’s High-Voltage, Reliable SiC MOSFETs

There’s a growing demand for Silicon Carbide (SiC) power products that improve system efficiency, robustness and power density in Automotive, Industrial and Mil/Aero applications. Microchip Technology Inc’s Microsemi subsidiary has announced the release of the SiC power device family, offering proven ruggedness and the performance benefits of wide-bandgap technology. The new SiC power device family complements Microchip’s microcontroller (MCUs) and analogue solutions, which is part of the growing family of SiC products within the Automotive industry, meeting the stringent requirements of Electric Vehicles (EVs) and other high-power applications in different markets.

Introducing the 700 V SiC MOSFETs and 700 V and 1200 V SiC Schottky Barrier Diodes (SBDs) to join Microchip’s current portfolio of SiC power modules, there are over 35 discrete products that offers outstanding ruggedness proven through rigorous testing, that are available in volume along with comprehensive development services, tools and reference designs. Microchip offers a broad family of SiC die, discrete and power modules in a range of voltage, current rating and package types.
Rich Simocic, the Senior Vice President of Microchip’s Discrete and Power Management unit said “SiC technology’s accelerated evolution and adoption has begun, and Microchip offers both a long heritage in this market and the ongoing commitment to playing a leadership role in ensuring that global supply continues to meet growing demand for these products… We are building out our portfolio with reliable products that are backed by the strong support infrastructure and supply chain that our customers need to execute and scale their development programs.”

Microchip’s SiC MOSFETs and SBDs offers more efficient switching at higher frequencies and with the ability to withstand ruggedness levels which are considered critical for promoting long-term reliability; these perform ~20% better than other SiC diodes in Unclamped Inductive Switching (UIS) ruggedness tests that measures performance of the devices that can withstand degradation or premature failure under avalanche conditions – Microchip’s SiC MOSFETs outperform competition products in the marketplace by demonstrating excellent gate oxide shielding and channel integrity with little lifetime degradation in parameters, even after 100,000 cycles of Repetitive UIS (RUIS) testing. These products are suitable for the growing number of EV systems including external charging stations, onboard chargers, DC-DC converters and powertrain/traction control solutions.
