Toshiba America Electronic Components, Inc. has launched a group of 30 microcontrollers (MCUs) based on the ARM Cortex-M3 core, the de facto standard for embedded 32-bit microprocessors. The M3H MCUs are the first product group in the new TXZ family of products, and are Toshiba’s first MCUs to be fabricated with an embedded flash memory process based on the 65nm logic process. Target applications include motor control, consumer electronics, office automation equipment, housing and facility equipment, audio-visual equipment, and a wide range of consumer and industrial applications.
The M3H group incorporates high-performance analog circuits and a wide range of basic functions required to support comprehensive motor control and consumer and industrial device applications. The devices operate at up to 40Mhz, and the line-up includes low-pin-count packages (32 to 100 pins) and small flash memory sizes (32KB to 128KB).
Features integrated into the M3H group include a high-precision 12-bit AD converter; 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. Incorporating this wide range of circuits allows the devices to simultaneously achieve both low-power characteristics and high-level functionality.
