Toshiba’s New 32-bit Microcontrollers to Improve Performance at Minimal Power Consumption for IoT Devices

Toshiba’s 32-bit microcontrollers TXZ+ Family

Toshiba Electronics has made major strategic expansions to its extensive line-up of microcontrollers with a new range of 32-bit microcontrollers. The TXZ+ Family is comprised of microcontrollers based on the Arm Cortex cores. The addition of a new product series to the TLCS Family is built on Toshiba’s original microcontroller core and introduces an 8-bit series.


The TXZ+ Family offers products in two classes viz. advanced and entry. The two advanced series, Cortex-M4 based TXZ4A+ Series and Cortex-M3 based TXZ3A+ Series are fabricated with 40nm-process and ensure to deliver maximum operating frequencies of 200 MHz The advanced series delivers better performance than Toshiba’s current microcontrollers and consumes approximately 30% less power than the existing Toshiba’s products.


The three entry class series viz. the Cortex-M4 based TXZ4E+ Series, the Cortex-M3 based TXZ3E+ Series, and the Cortex-M0 based TXZ0E+ Series reduce costs by limiting functionality. These three adopt the 130nm-process and are manufactured by Japan Semiconductor Corporation which is Toshiba’s manufacturing subsidiary.


TLCS-870/C1E Series which is the new addition to the TLCS Family also deploys SONOS memory. This SONOS (silicon-oxide-nitride-oxide-silicon) memory, a new technology for Toshiba’s microcontrollers that is highly suited to systems that demand highly reliable data retention and high-level resilience to repeated data write and erase.


Toshiba plans to deliver TXZ+ Family products on four platforms i.e. for general purposes and to support IoT functions for security, sensors and motor control. Sample shipments of TLCS Family products will start at the end of March and samples of the first product in the TXZ+ Family will start to ship in the second quarter of FY2020.
