Toshiba Electronics Europe has announced major strategic expansions to its already extensive line-up of 32-bit microcontrollers. The TXZ+ family is a new range based on Arm Cortex processor cores.

The family is split into two device classes with the first, the TXZxA+ advanced class 32-bit microcontrollers, fabricated in a 40nm CMOS process technology.

These features either an Arm Cortex-M3 or a Cortex-M4 with FPU processor core. The second is the TXZxE+ entry class using a 130nm CMOS process and utilising an Arm Cortex-M0, Cortex-M3, or Cortex-M4 processor core.

With the introduction of the new TXZ+ family, Toshiba focuses its microcontroller strategy on industry-standard Arm Cortex processor cores that are highly energy efficient and suitable for real time control applications. Enriched by Toshiba’s original and highly functional IP blocks, the devices are suitable for a variety of target applications such as home appliances, industrial and motor control applications as well as communication and data processing.

TheTXZxA+ advanced class is Toshiba’s 3rd generation of Arm Cortex core-based microcontrollers. The devices will provide enhanced performance with operating frequencies of up to 200MHz (254 DMIPS) while dissipating approximately 30% lower dynamic power compared to the existing 65nm devices. 

Toshiba will provide a line-up of microcontrollers that are functionally aligned pin-compatible to the existing 65nm TXZ devices enabling customers to seamlessly migrate to the new microcontroller family. Features will include a built-in high-precision oscillator and pre-drivers. A single-supply regulator that operates without the need for external capacitors to save on bill of material cost and board size is also integrated.

TXZxA+is a scalable platform with modular IP using a common register map that simplifies software design and re-use. A wide package line-up with intra-family footprint compatibility facilitates easier PCB design. Initial engineering samples are scheduled for Q3/2020 while customer samples and mass production are scheduled for Q2/2021.

The TXZxE+ entry class includes microcontrollers with essential functionality to serve basic control applications. They will be manufactured by Japan Semiconductor Corporation (JSC), a 100% subsidiary of TDSC, on JSC’s own 130nm CMOS process technology. Using its own fabrication facilities gives Toshiba full control for all aspects of the supply chain, from development of process technology to device development, design and manufacturing.

Customers will benefit from short production times, high reliability and longevity of supply. These are also Toshiba’s first microcontrollers featuring a SONOS (Silicon-Oxide-Nitride-Oxide-Silicon) memory, a new technology for non-volatile memory providing data retention and write endurance compared to conventional flash memory technology. Initial engineering samples are scheduled for Q2/2020 while customer samples and mass production are scheduled for Q4/2020.

Toshiba’s new TXZ+ microcontroller family will meet the increasing demand for energy saving by not only reducing its own power dissipation, but also by providing smarter control of attached sensors and actuators leading to significantly reduced system power consumption. Their improved performance and extended operating temperature range of up to +125°C will also make them suitable for a wide variety of applications, including use in harsh industrial environments.
