Toshiba Expands Lineup of Arm® Cortex®-M4 Based Microcontrollers for Motor Control
- M4K group(1) and M470 group support main control and motor control of consumer and industrial equipment -
Kawasaki, Japan--(ANTARA/Business Wire)-- Toshiba Electronic Devices & Storage Corporation ("Toshiba") has introduced seven 32-bit microcontrollers equipped with the Cortex-M4 core, expanding its extensive lineup of motor control microcontrollers. Six products constitute a new group, M4K group(1)[1], while one joins M470 group.
This press release features multimedia. View the full release here: https://www.businesswire.com/news/home/20250121621097/en/
The maximum operating frequency of the M4K group(1) microcontrollers is 120MHz, and 160MHz for M470 group. All are equipped with two motor control functions. In addition, like current products in both M4K group and M470 group, they are equipped with encoder interfaces and programmable motor control functions, which reduce CPU loads during motor control. They also inherit the checking mechanism for flash memory, RAM, AD converter and clock, and can be used for self-diagnosis functions. Sample programs, which will be used to obtain IEC 60730 Class B functional safety certification, are also provided to contribute to developing motor driven components for consumer and industrial equipment.
Current M470 group products have a maximum flash memory capacity of 512KB. The new addition to the M470 group boosts this to 1MB while still maintaining up to 100,000 program/erase cycles, supporting device functionality enhancements. Incorporation of a FOTA[2] function satisfies increasing needs for IoT support.
Along with samples, documentation, sample software, evaluation boards, and driver software with control interfaces for peripheral functions are available for use in preliminary evaluation. Development environments are provided in cooperation with ARM global ecosystem partners.
