Toshiba TXZ+ M4G group microcontrollers

Toshiba Electronic Devices & Storage has added 20 devices to its M4G group of microcontrollers for high-speed data processing — part of the TXZ+ family advanced class manufactured in a 40 nm process.

The products use Arm Cortex-M4 core with FPU, run up to 200 MHz, integrate a maximum of 2 MB code flash and 32 KB data flash memory with 100K write cycle endurance, and feature various interfacing and communication options. As a result, they are suitable for office equipment, building and factory automation applications.

Microcontrollers in the group have enhanced communication functions integrated as a serial memory interface that also supports Quad/Octal SPI, audio interface (I²S), external bus interface in addition to UART, FUART, TSPI and I²C. In addition, the devices have an in-built 3-unit DMAC and a bus matrix structure, designed to improve communication throughput compared to Toshiba’s conventional product.

The devices support a variety of sensing use cases with a high-speed, high-precision 12-bit analog/digital converter that allows individual sample hold times to be set for each AD input channel with up to 24 channels. The self-diagnosis functions for ROM, RAM, ADC and Clock help users to achieve IEC60730 Class B functional safety certification. The units offer low current consumption and high functionality while maintaining good compatibility with devices from the existing TXZ family M4G group.
