Toshiba TXZ+ Family Advanced Class M4N group microcontrollers

Toshiba Electronic Devices & Storage has introduced the M4N group of microcontrollers into its TXZ+ Family Advanced Class, manufactured in a 40 nm process.

The group includes an Arm Cortex-M4 core with FPU, running up to 200 MHz, with an integrated maximum 2 MB code flash and 32 KB data flash memory with maximum 100K write cycle endurance. The microcontrollers also offer various interface and communications options, such as Ethernet, CAN and USB 2.0 FS OTG controller with integrated PHY. The devices are suitable for office equipment, building and factory automation, and industrial networking and information management devices.

The products have enhanced communications functions integrated as a serial memory interface that also supports Quad/Octal SPI, an audio interface (I²S) and an external bus interface, in addition to UART, FUART, TSPI and I²C, which are supported by a built-in three-unit DMAC. Moreover, the devices can allocate independent DMA and RAM for each peripheral circuit, and use a bus matrix circuit configuration that enables efficient data transfers by the bus master. As a result, the devices enable Ethernet controller, CAN and USB controller to be processed independently in parallel at the same time.

The devices support a variety of sensing applications 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 incorporated for ROM, RAM, ADC and clock help users to achieve IEC60730 Class B functional safety certification.
