The MCU is made for motor management in followers, instruments, and extra. It runs quick, saves energy, provides security, and comes with software program assist.
Renesas Electronics Company has launched the RA2T1 group of microcontrollers (MCUs), designed for environment friendly single-motor management in home equipment equivalent to followers, energy instruments, vacuum cleaners, printers, and extra. Constructed on a 64 MHz Arm Cortex-M23 core, the MCUs mix exact motor management, built-in security options, and broad software program assist to assist builders pace up product design.
Key motor management options embody a 3-channel sample-and-hold (S&H) operate that reads 3-phase present values of BLDC motors concurrently, enabling extra correct management than sequential sampling. The MCUs additionally provide complementary PWM with computerized dead-time insertion and uneven PWM era, bettering efficiency in inverter drive purposes.
To boost system security, the RA2T1 supplies a Port Output Allow operate and high-speed comparators that may immediately shut off PWM indicators when overcurrent situations are detected. These security responses are configurable primarily based on the inverter’s necessities.
The MCU is supported by Renesas’ Versatile Software program Bundle (FSP), which incorporates middleware, peripheral drivers, a number of RTOS choices, and reference software program for motor management, AI, and cloud connectivity. FSP permits code reuse, helps legacy integration, and simplifies migration throughout the RA MCU household.
A number of the key options of the MCU consists of:
- Core: 64 MHz Arm Cortex-M23
- Reminiscence: 64KB Flash, 8KB SRAM, 2KB Information Flash
- Analog: 12-bit ADC with 3-channel S&H, temperature sensor, inner reference, 2 high-speed comparators
- System: On-chip oscillators (excessive/mid/low), clock output, power-on reset, voltage detection, occasion hyperlink, information switch, interrupt management, low-power modes
- Security: PWM shutdown, SRAM parity verify, ADC self-test, clock accuracy verify, unlawful reminiscence entry detection
- Working Temp: -40°C to 125°C
- Voltage Vary: 1.6V to five.5V
- Packages: 48-LQFP, 32-LQFP, 48-QFN, 32-QFN, 24-QFN (4×4 mm)
“Prospects have trusted Renesas motor management options for a few years throughout 1000’s of programs,” mentioned Daryl Khoo, Vice President of Embedded Processing Advertising and marketing Division at Renesas. “The RA2T1 MCUs improve our management on this space with market-leading expertise, low-power operation, and legendary Renesas high quality and security requirements for single-motor programs.”
