Acroview, a leader in chip programming, has announced further expansion of its compatible chip model coverage with the release of a new version of its programming software. The company's core product, the universal programming platform AP8000, has now been fully adapted to support SinOne's motor drive microcontroller SC32M155C6P.

The SC32M155C6P is an industrial-grade, 32-bit Flash microcontroller based on the Arm Cortex®-M0+ core, designed specifically for motor drive applications, with an operating frequency of up to 72MHz. The Cortex®-M0+ core uses a 32-bit reduced instruction set (RISC) and complies with the CMSIS standard.

The SC32M155C6P features powerful data processing capabilities. The integrated Direct Memory Access (DMA) controller enables high-speed data transfer, while the hardware CRC module and the integrated MathRhythm (MR) unit further accelerate data computation.

The SC32M155C6P microcontroller embeds a high-precision high-frequency internal oscillator (HIRC) and a low-frequency 32kHz internal oscillator (LIRC), and also provides an interface for an external 32.768kHz low-frequency crystal oscillator (LXT). Both the embedded clock sources and the external crystal interface can provide clock signals for the system. The built-in system clock monitoring module has a clock source switching function: when the system clock becomes abnormal, it can automatically switch the clock source to the HIRC to ensure stable system operation.

The SC32M155C6P microcontroller is rich in peripherals, including: up to 44 GPIOs with external interrupt capability, four 16-bit timers, eight channels of 16-bit enhanced multi-function EPWM (with complementary dead-time and fault detection), three independent UARTs (UART2 has a full LIN interface supporting master/slave mode), an independent CAN interface (supporting CAN specification 2.0B and CAN FD), two SPIs, two TWIs, an independent PCAP module, two independent QEP modules, three analog comparators CMP0~2, and an additional independent analog comparator CMP3. Furthermore, it features three independent operational amplifiers, a 10-bit DAC, 18 channels of 12-bit high-precision high-speed ADC (supporting dual-channel simultaneous sample-and-hold and threshold alarm), a temperature sensor module, an independent watchdog timer (WDT), and a low-voltage reset circuit (LVR), effectively enhancing system reliability.

The SC32M155C6P microcontroller supports a wide operating voltage range of 2.0-5.5V and can operate at ambient temperatures from -40°C to 105°C. Additionally, this series offers three power modes to meet the power consumption requirements of different application scenarios, achieving a balance between high performance and low power.

The SC32M155C6P microcontroller uses industry-leading eFlash process technology, with Flash write endurance of over 100,000 cycles and data retention of 100 years at room temperature. It exhibits excellent ESD performance and EFT immunity. The SC32M155C6P provides up to 128 Kbytes of APROM space, 8 Kbytes of SRAM (with parity check support), 2 Kbytes of user storage area (EEPROM-like), and 4 Kbytes of system memory area (LDROM). The built-in system memory area supports OTA upgrades, and multiple program upgrade methods such as ISP (In System Programming), ICP (In Circuit Programming), and IAP (In Application Programming) are available, allowing on-board debugging and program upgrades online or under power.

The SC32M155C6P offers excellent characteristics combined with outstanding anti-interference performance, making it suitable for various motor drive solutions and main control solutions. Application areas include: motor drives, smart home appliances, smart home, IoT, new energy, and other industrial control and consumer fields.
