Toshiba TXZ+ Family Advanced Class M3H group of microcontrollers

Toshiba Electronic Devices & Storage has released the M3H group of microcontrollers in the TXZ+ Family Advanced Class, manufactured in a 40 nm process.

The group includes an ARM Cortex-M3 core running up to 120 MHz, integrated max 512 KB code flash and 32 KB data flash memory with 100K write cycle endurance. The microcontrollers also offer various interface and motor control options, such as UART, I²C, Encoder and Programmable Motor Control. The devices are suitable for a wide range of applications including motors, home appliances and industrial equipment.

In response to the diversity of consumer equipment, the 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 provide a flexible board layout.

The 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 are suitable for controlling AC motors and brushless DC motors in combination with an advanced programmable motor control circuit that can operate synchronously with the ADC. The self-diagnosis functions incorporated in the devices for ROM, RAM, ADC and Clock help users to achieve IEC60730 Class B functional safety certification.
