Toshiba M4N Group of Microcontrollers

Toshiba Electronic Devices & Storage Corporation has added 20 new microcontrollers to its M4N group. The new devices offer various interface and communication options and are suitable to be used in office equipment, building and factory automation, and industrial networking and information management systems. The M4N group features include Arm Cortex-M4 core with FPU, running up to 200MHz, with an integrated maximum 2MB code flash and 32KB data flash memory with maximum 100K write cycle endurance.

These new microcontrollers in the group have enhanced communications functions integrated as a serial memory interface that 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 3-unit DMAC. They 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 M4N group microcontrollers can allocate independent DMA and RAM for each peripheral circuit, and use a bus matrix circuit configuration that ensures efficient data transfers by the bus master. Moreover, the self-diagnosis functions incorporated in these devices for ROM, RAM, ADC and Clock help customers to achieve IEC60730 Class B functional safety certification.
