Cortex-M-based MCUs aim for low power and connected-device designs

August 26, 2015 // By Graham Prophet
Toshiba Electronics Europe adds to its ARM Cortex-based microcontrollers with the TXZ family that supports low-power consumption and high-speed operation for IoT and M2M designs.

The TXZ family has been designed for low power consumption by integrating the ultra-low power design technologies from Toshiba’s TZ series of ApP Lite application processor family for IoT solutions, into the current TX family of microcontrollers. Fabricated using an embedded flash memory process based on a 65nm logic process, the TXZ series will reduce power consumption by 60% compared to Toshiba’s current microcontroller products.

The first product group will be the TMPM3H, part of the TXZ3 series that will be based on the ARM Cortex-M3 core. The TMPM3H group will feature products characterised by small packages with pin counts of 32-100 pins, flash memory capacities of 32 kB-128 kB and standard peripheral functions. Toshiba expects the devices to reduce entire system power consumption, targeting less than 100 µA/MHz. Sample shipments will start in the second quarter of 2016.

Toshiba adds that 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. The company says it has also started to develop microcontrollers with embedded non-volatile memory (NVM) that adopts single-poly multi-time programmable cells on its 130 nm logic process technology. These devices will help to reduce cost in applications including power management and motor control. Sample shipments will start in the fourth quarter of 2015. Anticipated product introductions, by individual part-number-configuration variants will amount to 180 products by 2017 and a further 120 by 2018.
