Toshiba begins shipping engineering samples of entry-level TXZ+™ M4H family microcontrollers with Arm Cortex-M4 core for system control applications
—Standard microcontrollers supporting diverse system control applications for consumer products and industrial equipment—
Kawasaki, Japan–(ANTARA/Business Wire)– Toshiba Electronic Devices & Storage Corporation (Toshiba) has announced the entry-level TXZ+™ M4H family of standard microcontrollers[1], equipped with an Arm® Cortex®-M4 core featuring a Floating-Point Unit (FPU). The new microcontrollers are designed for small-scale system control in consumer products such as air conditioners and washing machines, as well as industrial equipment including multifunction printers and factory automation systems. Toshiba is now providing engineering samples of the new product.
As consumer and industrial products become increasingly sophisticated and diverse, system control microcontrollers must offer enhanced real-time capabilities and stability, simplify design processes, provide versatility for long-term operation, and maintain flexibility for derivative product development. Toshiba has addressed these challenges with the TXZ+™ M4H entry-level family for system control applications, emphasising flexibility.
Designed as an entry-level product, the microcontrollers feature an Arm® Cortex®-M4 core with FPU and a maximum operating frequency of 120 MHz, delivering the computational performance and responsiveness required for consumer and industrial products, while handling core system control applications such as logic control, interface processing, and timing control.
The M4H family supports a supply voltage range of 2.7 V to 5.5 V, and its integrated high-speed oscillator with ±1% accuracy reduces the need for external components, enhancing design flexibility. These characteristics make it suitable for consumer and industrial products operating on 5 V power supplies.
The microcontrollers also include essential peripheral functions for system control, such as a 12-bit Analogue-to-Digital Converter (ADC), timers, Universal Synchronous Receiver/Transmitter (UART), Serial Peripheral Interface (SPI), Inter-Integrated Circuit (I²C[2]), and Direct Memory Access (DMA[3]). An additional feature is the Advanced Programmable Motor Driver (A-PMD), which supports brushless DC motor control, ensuring application-specific flexibility and system configuration adaptability.
Toshiba supports device evaluation and review processes by providing engineering samples and development environments. The company also facilitates the smooth transition from initial evaluation to application development through starter kits, sample software, CMSIS[4]-compatible drivers, and support for major Integrated Development Environments (IDEs[5]).
Toshiba will continue to expand these support resources, including documentation, and further strengthen its microcontroller portfolio to meet diverse needs.
