Toshiba Electronics Europe is improving its line of ARM Cortex-based MCUs with the development of the TXZ family of MCUs that support low-power consumption and high-speed operation for the Internet of Things (IoT) and M2M ecosystems.

The TXZ family has been designed to meet market needs for low power consumption systems by integrating the ultra-low power design technologies adopted in Toshiba's TZ series of ApP Lite application processor family for IoT solutions into current TX family of MCUs.

ARM Cortex-M3

Fabricated using an embedded flash memory process based on a 65nm logic process, the TXZ series will reduce power consumption by 60 per cent compared to Toshiba's current MCU products, the company indicated.

The first product group will be the TMPM3H, part of the TXZ3 series that will be based on ARM Cortex-M3 core. The TMPM3H group will feature products characterized by small packages with pin counts of 32-100 pins, flash memory capacities of 32KB to 128KB and standard peripheral functions. Toshiba expects the devices to reduce entire system power consumption, targeting less than 100μA/MHz for the MCUs. Sample shipments will start in 2Q16.

Toshiba will continue to broaden the group line-up. It will launch a second product group of high-speed products based on the ARM Cortex-M4F core and a third product group featuring ultra-low power consumption products based on the same core.

Toshiba has also started to develop MCUs with embedded non-volatile memory (NVM) that adopts single-poly multi-time programmable cells on its 130nm logic process technology. These devices will help to reduce cost in applications including power management and motor control. Sample shipments will start in 4Q15.
