FPU Core Based Microcontrollers

Toshiba has added eight new products with 512KB/1MB flash memory capacity and four types of packages to the M4K Group of the TXZ+ Family Advanced Class 32-bit microcontrollers equipped with Cortex-M4 core with FPU. These microcontrollers offer various interfaces and motor control options, such as advance-programmable motor driver (A-PMD), advanced encoder 32-bit (A-ENC32), advanced vector engine plus (A-VE+) and three units of high-speed, high-resolution 12-bit analog/digital converters. As a result, the M4K Group products contribute to wider application of IoT, and bring advanced functionality to AC motors, brushless DC motors and inverter controls.

These new products expand code flash memory capacity from the 256KB maximum of Toshiba’s current product to 512KB/1MB, depending on the product, and RAM capacity from 24KB to 64KB. Other features, such as an Arm Cortex-M4 core running up to 160MHz, integrated code flash and 32KB data flash memory with 100K program/erase cycle endurance, have been maintained. Devices in the M4K Group have UART, TSPI and I2C integrated as general communications interfaces. Self-diagnosis functions incorporated in the devices for flash memory, RAM, ADC and Clock help customers to achieve IEC 60730 Class B functional safety certification.

Key Features

  • High-performance Cortex-M4 core with FPU, max 160MHz

  • Increased capacity of internal memory

  • Memory swap method firmware rotation function, supporting firmware updates while the microcontroller continues to operate

  • Self-diagnosis functions for IEC 60730 class B functional safety

  • Four types of packages
