Toshiba has announced “a significant strategic expansion of the already extensive line of microcontrollers.” We are talking about the TXZ + family, which includes 32-bit microcontrollers based on Arm Cortex processor cores. The family is divided into two classes. The first, TXZxA +, includes more complex models based on the Arm Cortex-M3 or Cortex-M4 core with FPU, manufactured at 40 nm standards. The second, TXZxE +, includes entry-level models on the Arm Cortex-M0, Cortex-M3 or Cortex-M4 core, manufactured at 130 nm standards.
The manufacturer attributes the advantages of Arm Cortex cores to high energy efficiency and suitability for real-time control applications. Microcontrollers equipped with original IP-function blocks developed by Toshiba specialists are suitable for consumer and industrial electronics, engine control systems, communications and data processing. The manufacturer notes that the TXZxA + microcontrollers are functionally and at the output level compatible with existing TXZ microcontrollers manufactured according to the standards 65 nm, but dynamic heat dissipation is about 30% better. The presence of a power regulator in them allows you to do with a single supply voltage, which simplifies the list of components and board sizes. Engineering samples of these microcontrollers should appear in the third quarter of 2020, and familiarization samples and serial products in the second quarter of 2021. As a feature of the TXZxE + microcontrollers, the presence of non-volatile SONOS memory (the first in Toshiba microcontrollers) is allocated, which surpasses flash memory in reliability and durability . Engineering samples of these microcontrollers should appear in the second quarter of 2020, and familiarization samples and serial products in the fourth quarter of 2020.
