Toshiba expands line-up of Arm Cortex-M3-based MCUs

August 16, 2018 // By Julien Happich
Toshiba Electronics Europe has launched the second M3H group in its TXZ family of low-power, high-speed microcontrollers based on the Arm Cortex-M3 core. The new M3H-devices incorporate high-performance analog circuits and the wide range of basic functions required to support comprehensive motor control for applications in consumer and industrial devices.

The line-up includes a range of 64 to 144-pin packages, 256 to 512KB of flash memory, and 32KB data flash memory. The operating frequency is 80MHz, twice the speed of the first M3H group. Integrated features include high-precision analog circuits such as a 12-bit ADC converter with 1.5μs conversion speed with up-to 21 channels, and an 8-bit, 2 channel, DAC. Toshiba’s Advanced-Programmable Motor Driver (A-PMD), a single channel motor control circuit that provides inverter control of brushless DC motors is also built-in. The IC also incorporates versatile general-purpose peripheral circuitry including up to 6 UART channels, 2-4 channel I2C, 1-5 channels TSPI, and multiple channels of 16- and 32-bit timers.

These high-precision analog and general-purpose peripheral circuits allow the second M3H group to achieve low-power operation simultaneously with high performance for high-end home appliances and large-scale systems.

In addition there is a built-in self-diagnosis function that checks the reference voltage in the ADC, a RAM parity function to detect errors during memory reads, and a single channel CRC calculation circuit that contributes to reducing software processing loads to comply with the IEC 60730 functional safety standard. The MCUs require a power supply of 2.7 to 5.5V and operate from -40 to 85°C.
