ARM® Cortex® -M3-based General Purpose Microcontrollers for Consumer Devices (Under Development)

TOKYO- Toshiba Corporation's (TOKYO: 6502) Storage & Electronic Devices Solutions Company today announced the launch of "M3H Group(1)" microcontrollers based on the Arm Cortex-M3 core, the first product group in the TXZ™ Family, a new family of products fabricated with embedded flash memory process based on the 65nm logic process. Sample shipments of the M3H Group(1) will start in May 2016, and mass production of the first products to be released will start in January next year. Products in the M3H Group are Toshiba's first microcontrollers to employ the 65nm flash embedded logic mixed process.

The M3H Group(1) is based on the Arm Cortex-M core, the de facto standard for embedded 32-bit microprocessors, and incorporates high-performance analog circuits and the wide range of basic functions required to support comprehensive motor control and consumer and industrial device applications. The line-up includes low-pin-count packages (32 to 100-pin) and small flash memory sizes (32KB to 128KB).

Integrated features include a high-precision 12-bit AD converter with a 1.5μs conversion speed and an 8-bit DA converter; Toshiba's programmable motor control circuit (PMD) suitable for inverter motor control, including AC motor and BLDC motor control; and versatile general-purpose peripheral circuits including UART, I2C, TSPI, and timers. Incorporation of these high-precision analog circuits and general-purpose peripheral circuits allows the M3H Group to achieve low-power characteristics and high level functionality at the same time.
During sample shipment, Toshiba will provide technical documentation, software in which the concrete embedded examples are written, evaluation boards, and driver software for each control interface. Beyond this, various development environments satisfying diverse needs can be realized by collaboration with Arm ecosystem partners worldwide.
Toshiba continues to expand the line-up of the TXZ Family to meet the needs of the motor control and global sensing market.
