The M3H Group has two groups based on their functional level. “M3H Group (1)” offers standard functions, while “M3H Group (2)” offers an expanded package line-up and memory size and supports high-speed processing (80MHz). Together, they offer a rich line-up with 13 packages (32 pins to 144 pins) and flash memory ranging from 32KB to 512KB.

The M3H Group is based on the global standard Arm Cortex-M3 core designed for motor control and to meet diverse requirements for consumer and industrial equipment. Operation frequency is up to 40MHz for M3H Group (1) and 80MHz for M3H Group (2).

In addition to high-precision analog circuits, including a 12-bit AD converter (up to 21 channels) with 1.5μs conversion speed, and an 8-bit DA converter (2 channels), M3H Group (2) incorporates Advanced-Programmable Motor Driver (A-PMD), Toshiba’s motor control technology for inverter motor control of brushless DC motors. A-PMD realizes low power consumption and advanced functions, while incorporating highly versatile peripheral circuits, such as UART, I²C, TSPI and timers, and supports high-end home appliances and large-scale systems.
