Toshiba Electronics Europe has added the M4G Group to its TXZ Family of ARM Cortex-M4-based microcontrollers for office automation (OA) equipment, audio-visual (AV) equipment, and industrial equipment.

The M4G Group is based on the ARM Cortex-M4 core with a floating-point unit (FPU). It incorporates high-performance analog circuits, a wide range of timers and communication channels, and is available in a variety of packages, from 100 to 177 pins, with onboard flash memory ranging from 512kB to 1536kB alongside up to 194kB of RAM and 32kB of data FLASH that can be rewritten up to 100,000 times. Operating frequency is up to 160MHz and the MCUs have an operating temperature range of -40 to +85°C.

In addition to high-precision analog circuits that include a 12-bit AD converter (up to 24 channels) with a 1.0μs conversion speed, and an 8-bit DA converter (2 channels), the M4G Group incorporates two DMA controllers; a high-speed DMA controller and a multi-function DMA controller. Both realize low power consumption and advanced functions, while incorporating highly versatile peripheral circuits, such as serial memory interface (SMIF), UART, I2C, TSPI, timers, and support for large-scale systems. A built-in interlinking function for timers, UART, and TSPI, and an interval sensor detection circuit (ISD), contribute to reduced loads in software processing. The products will begin mass production throughout the next six months.
