Toshiba Launches New M4G Group Microcontroller Based on Arm Cortex-M4 for High Speed Data Processing in TXZ+TM Advanced Series

     Toshiba Electronic Components and Storage Devices Co., Ltd. announced that it has started mass production of 20 new devices for high-speed data processing in the M4G group. The M4G group is a new member of the advanced series of TXZ+TM family, which is manufactured with a 40nm process. These products use the Arm Cortex-M4 core with FPU and run at a frequency of up to 200MHz. They are internally integrated with 2MB code flash memory and 32KB data flash memory. They have a write cycle durability of 100000 times. In addition, they also provide a wealth of interfaces and communication options. Therefore, M4G devices are very suitable for office equipment, building and factory automation applications.

     The microcontroller in the M4G group is configured with enhanced communication functions. In addition to UART, FUART, TSPI and I2C, it also supports Quad/Octal SPI, audio interface (I2S) and external bus interface. In addition, these devices have built-in 3-unit DMAC and bus matrix structures, which greatly improve the communication throughput compared with traditional products.

     The microcontroller is configured with a high-speed, high-precision 12 bit analog/digital converter, which supports up to 24 analog to digital conversion input channels. They can set the sample and hold time separately, so that the device can support a variety of sensors.

     These devices can provide self diagnostic functions for ROM, RAM, ADC and clock, and help customers pass IEC60730 Class B functional safety certification. These new devices not only achieve low current consumption and high functions, but also maintain good compatibility with existing TXZTM series M4G (1) devices.
