Flexibility for high-end applications from new microcontrollers

Infineon Technology is adding the XMC7000 series to its microcontroller portfolio. The XMC7100, the XMC7200, and the associated evaluation kit are available from Rutronik.

The new MCU family includes a single- or a dual-core Arm Cortex-M7 core, with Arm Cortex-M0+ support. Thanks to 40nm process technology, the low-power MCU allows computational performance designed for high-end industrial applications, including high-accuracy PMW generation for motor power stage control and RADAR-based sensing level measurement. Conceivable applications include motor control, industrial drives, EV charging, e-bikes, robotics, BMS, PLC, and I/O applications. An evaluation kit is also offered for the microcontrollers. Together with the ModusToolboxTM, it guarantees an easy entry into design and development.

The MCUs offer a special feature: Their dual-bank flash allows firmware updates over the air via RWW. For example, a firmware update may be loaded onto one flash bank whilst the device is still running with the previous firmware on the second flash bank. A reboot then switches to the new firmware. That makes the family very flexible, particularly in remote maintenance. Up to 8MB Flash and 1MB RAM are also part of the equipment.

The microcontroller provides a wide supply voltage range from 2.7V to 5.5V. In the Hibernate Mode – the lowest low-power mode – the MCU's power consumption is only 8µA. Furnished with a broad variety of peripherals such as up to 2x Gigabit Ethernet, CAN-FD, Crypto Engine, SMIF, and SDHC, the microcontroller impresses with its flexibility.

Ideal for harsh environments, the controller can operate from -40C to +125C and is provided in various TQFP and LFBGA package types with 100 to 272 pins.
