MCUs That Combine CAN FD (Flexible Data-Rate) And Core Independent Peripherals
Posted by on
Microchip Technology announced its PIC18 Q84 family, a series of microcontroller units (MCU) that supports data transmission and reception through a CAN FD network. The CAN FD port meets the demand for increased bandwidth in CAN applications. The CAN FD module supports the CAN 2.0B standard and thus is fully backward compatible with previous CAN Bus modules.
The MCU series allows increased bandwidth and flexible data-rates in automotive applications such as safety and communication while also supporting advanced driver assistance systems (ADAS). Accompanied by an array of core independent peripherals (CIPs) that handle various tasks without requiring CPU (central processing unit) intervention, the MCU series cuts both time and cost when connecting to a CAN FD network.
The products offer moving sensor data to a CAN FD network, without the need for gateways or network switching technologies. Also, its configurable CIPs facilitate customized hardware development for automotive and industrial designs. Additional code is not required. Available peripherals include a 32-bit cyclic redundancy check with Scan (CRC/Scan) and a windowed watchdog timer (WWDT) for functional safety capabilities, and a JTAG (Joint Test Action Group) interface for industry-standard testing and debugging.
The MCUs come with both hardware and software support. Hardware includes a Curiosity Nano Evaluation kit (DM182030) and a Curiosity High Pin Count (HPC) development board. A plug-in module (PIM) is also available for the automotive networking development board and the Microchip development board. The software includes the company’s MPLAB Code Configurator (MCC). Microchip also provides a family of CAN FD transceivers and CAN FD controllers.
Teensy 4.1 Triple CAN Bus Board with 240x240 LCD and Ethernet
The Teensy 4.1 board comes with triple CAN Bus connections, two CAN 2.0B and one CAN FD, and ethernet magjack. It can be powered by an external +12 VDC with reverse voltage protection. Included is also a 240x240 wide-angle IPS TFT LCD display.
The Teensy 4.1 is an Arduino-compatible board with an Arm Cortex-M7 microcontroller running at 600 MHz. The board is compatible with the Arduino IDE and the Arduino library. In most cases, code written for another Arduino board works with a minimum of changes on a Teensy. As the name implies, the board is tiny. For example, the current form factor is only about 18 by 36 millimeters. However, do not let the size mislead you; these boards pack a ton of functionality. For example, the new Teensy 4.1 features a megabyte of RAM, two megabytes of Flash, a bevy of I/O options, cryptographic support, a hardware floating-point processor (FPU), and a built-in real-time clock (RTC).
