Toshiba Expands Lineup of Arm Cortex-M4 Based Microcontrollers for Motor Control
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.
The
maximum operating frequency of the M4K groupmicrocontrollers 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 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.
