Toshiba expands the TXZ+TM family for high-speed data processing

These M4G group products are now part of the TXZ+ family advanced class and are manufactured in a 40nm process.

These products (and others in the TXZ+ family) are intended for a wide range of applications including office equipment (multi-function printers), audio/video (AV) equipment, IoT, home appliances, building automation and factory automation – or anywhere where high-speed data processing is required.

All of the devices use Arm Cortex-M4 core and include a floating-point unit (FPU) that runs at speeds up to 200MHz. They also integrate 2048kB of flash memory for code, a further 32kByte of data flash with 100k write cycles endurance and 4kB of user data flash. The MCUs also incorporate multiple interfaces and various communication options.

All devices in the M4G group have enhanced communication functions integrated as a serial memory interface. Among the standards supported are quad / octal SPI, audio interface (I2S), as well as UART, FUART, TSPI and I2C. A three-unit DMAC and bus matrix structure significantly improves communication throughput when compared to conventional products.

The devices support a variety of sensing applications due to their high-speed, high-precision 12-bit analogue/digital converter (ADC) that allows individual sample-and-hold times to be set for each input channel with up to 24 channels. These devices provide highly effective solutions for AC motor, brushless DC motor (BLDC) with the integration of Toshiba’s advanced programmable motor driver (A-PMD).

The self-diagnosis functions incorporated in the devices for ROM, RAM, ADC and the clock support the achievement of IEC60730 Class B functional safety certification. These devices also offer low current consumption and high levels of functionality while maintaining good compatibility with devices within the existing TXZ family M4G group.

Comprehensive documentation, sample software (with examples of actual usage), and driver software for each peripheral are available for free download on Toshiba website.
