Microcontrollers for industrial equipment requiring Ethernet and CAN controller

Toshiba Electronics Europe GmbH has released 20 new devices in the M4N group of ARM Cortex-M4 microcontrollers produced in a 40nm process. These devices extend and enhance the TXZ+ family advanced class and incorporate an ARM Cortex-M4 core with FPU, running at speeds up to 200MHz, integrated 2MB code flash, and 32kB data flash memory with 100k write cycle endurance. These new microcontrollers also provide various interfacing and communication options such as Ethernet, CAN and USB 2.0 FS OTG with integrated PHY.

These types of microcontrollers are ideal for office equipment, building and factory automation applications, and industrial networking and information management devices. Within the consumer space, these devices are ideal for IoT-based home appliances, home security, smart meters and more.

The new products offer enhanced communication functions integrated, incorporating a serial memory interface that also supports Quad/Octal SPI, audio interface (I2S) and external bus interface as well as to UART, FUART, TSPI, and I2C supported by a built-in three-unit DMAC. Moreover, the devices can allocate independent DMA and RAM for each peripheral circuit and utilise a bus matrix circuit configuration that enables the bus master to efficiently transfer data. As a result, these devices allow an Ethernet controller, CAN, and USB controller to be processed independently in parallel at the same time.

The new devices support various sensing applications with a high-speed, high-precision 12-bit ADC that provides individual sample and hold times to be set for each of the 24 ADC input channels. A dual-channel 8-bit DAC and a range of motor control functions are also provided in the new devices.

The self-diagnosis functions included in the devices for ROM, RAM, ADC and clock help customers to achieve IEC60730 Class B functional safety certification.

The new devices are offered in a selection of fine-pitch LQFP and VFBGA packages.
