Toshiba has launched five groups of 32-bit microcontrollers, under the the TXZ+™ family. The M4K, M4M, M4G, and M4N groups are based on the Arm Cortex-M4 core, and the M3H group is based on the Arm Cortex-M3 core. All groups offer low power consumption, suitable for a wide variety of applications such as motor control, connected IoT devices and leading-edge sensing functionalities.
The advanced class has a maximum operating frequency of 200MHz, flash memory of max. 2MB and 12-bit analog-to-digital converters. They are equipped with application-focused peripherals such as high-efficiency motor control engines or rich connectivity interfaces.
Features and Applications
The M4K group is suitable for high performance motor control applications such as air conditioners, washing machines, refrigerators, inverter pumps, actuators and power tools. Key features include motor control hardware, and a self-diagnosis function for home appliance functional safety standard IEC 60730
The M4M group, which adds a CAN interface to the M4K group functionality, is suitable for industrial equipment applications such as factory automation, building automation, robots, cobots and automated guided vehicles (AGV).
The M4G group targets office automation equipment that require high-speed data processing and large flash memory capacities, such as multi-function printers and AV devices. Features include a maximum operating frequency of 200MHz, flash memory of max. 2MB, interfaces for high- speed communications, analog circuits for multiple sensor connections, and high reliability firmware updating for secure processing.
The M4N group is suitable for networking and information management devices, such as printers and other office equipment requiring Ethernet and USB connectivity. Features include a maximum operating frequency of 200MHz, max. 2MB flash memory, various interfaces for IoT devices (sensing and communication), and support for high speed data transfers
The M3H group is excellent for basic processing and motor control applications in home appliances, office equipment, or other consumer devices. Products feature an integrated LCD display function, self-diagnosis function for home appliance functional safety standard IEC 60730, and high efficiency motor controls. System cost reduction is supported by reducing the overall Bill of Materials (BoM).
Engineering samples will start to ship between January and March 2021, and mass production will start in the second half of the year. Associated documentation, development tools and sample software will also be provided.
