Toshiba: New M3H Group of ARM(R) Cortex(R)-M3 Microcontrollers in the TXZ+(TM) Family Advanced Class (Graphic: Business Wire)
In response to the diversity of consumer equipment, the new M3H group products have enhanced communications functions integrated as UART, TSPI, I2C, and a 2-unit DMAC. Moreover, a digital LCD driver is integrated to reduce the number of components for display function, facilitate contrast adjustment, and ensure a flexible board layout.
These devices support a variety of sensing applications with a high-speed, high-precision 12-bit analog/digital converter (ADC) that allows individual sample and hold times to be set for each of the 21 ADC input channels. In addition, they provide a solution suitable for controlling AC motors and brushless DC motors in combination with an advanced programmable motor control circuit that can operate synchronously with the high-speed, high-precision 12-bit analog/digital converter.
The self-diagnosis functions incorporated in the devices for ROM, RAM, ADC and Clock help customers to achieve IEC60730 Class B functional safety certification.
Documentation, sample software with actual usage examples, and driver software that controls the interfaces for each peripheral can be downloaded from the Toshiba website. Evaluation boards and development environments are provided in cooperation with ARM global ecosystem partners.
