Toshiba Electronic Devices & Storage Corporation has extended the TXZ+™ Family Advanced Class with 21 new microcontrollers in the M3H group that have enhanced communications functions integrated as UART, TSPI, I2C, and a 2-unit DMAC. These microcontrollers offer various interface and motor control options and are suited for a wide range of applications including motors, home appliances, and industrial equipment.
The M3H group includes an ARM Cortex-M3 core running up to 120MHz, integrated max. 512KB code flash, and 32KB data flash memory with 100k write cycle endurance. 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. 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.
- High-performance ARM Cortex-M3 core, max 120MHz
- Optimized for consumer equipment with a wide range of memory and package lineup
- Self-diagnosis functions for IEC60730 class B functional safety
In addition, these devices 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.
