The microcontrollers offer improved motor control, features, and applications in appliances, industrial equipment, and automotive systems.
Toshiba Electronics Europe GmbH has expanded its TXZ+ Family Advanced Class of 32-bit microcontrollers by introducing sixteen new models with 1MB/512KB memory capacities. These models are available in four packaging options to enhance motor control in consumer and industrial products.
These microcontrollers are equipped with an Arm Cortex-M4 processor with speeds up to 160MHz, integrated with flash memory supporting up to 100,000 cycles. They are ideal for home appliances like washing machines and freezers, with IEC 60730 Class B safety certification. They also support HVAC and heat pump applications by driving up to three motors with one MCU. Industrial equipment can benefit from field-oriented control for motors, and automotive manufacturers might use the M4M group for its CAN communication interface and motor control capabilities.
The M4K and M4M series feature a motor driver, a 32-bit encoder, a vector engine, and triple 12-bit converters for controlling PMSM and BLDC motors. The 1MB flash memory in the TMPM4KxF10AxxG and TMPM4MxF10AxxG models is split into 512KB segments, aiding reading and programming. This dual-segment approach facilitates updates through rotation and swapping.
The microcontrollers come with communication interfaces such as UART, TSPI, and I²C, with the M4M series also including a CAN communication interface. Embedded features help monitor flash memory, RAM, ADC, and clock components to achieve IEC 60730 Class B certification. These microcontrollers can manage up to three motors in a single unit, making them suitable for heat pumps and HVAC systems.
The company provides support for these microcontrollers, including documentation, sample software for applications, and driver software for managing interfaces. The available package types cater to specific communication needs and functionalities, ranging from 87-pin ports in LQFP100 and QFP100 packages to 51-pin ports in 10 x 10mm or 14 x 14mm LQFP64 packages.
