Key Features

• Core Arm Cortex-M0+ 32-bit CPU running up to 80 MHz (up to 64 DMIPS) with cache buffer (flash accelerator) support for improved code fetch performance.
• Memory 64 Kbytes of code Flash (Flash accelerator; 27 MHz flash access speed) and 8 Kbytes of SRAM for application and runtime data.
• Power and Clock Operates from 2.7–5.5 V. Multiple clock sources including internal and external oscillators (HSI 32 MHz, LSI 500 kHz, HSE 4–16 MHz, LSE 32.768 kHz) and PLL support for flexible system clocks; low-power modes: SLEEP and DEEP-SLEEP.
• Timers and Motor PWM Multiple timers including four 16-bit timers and one 32-bit timer, plus a 3-phase MPWM generator with 16-bit up/down counters and six ADC trigger sources—suited for motor and PWM-driven loads.
• Analog 12-bit ADC with 10 channels (multiple conversion modes), one comparator and two operational amplifiers for sensor conditioning and control loops.
• Connectivity Standard serial interfaces including I2C, SPI and UART/USART for peripheral and HMI connectivity.
• System Support DMA controller with four channels, CRC calculation unit with multiple CRC modes and Serial Wire Debug (SWD) for development and reliability features.
• I/O and Package 30 general-purpose I/O pins in a 32-LQFP surface-mount package (7 × 7 mm, 0.5 mm pitch) for compact board designs.
• Environmental Range Commercial-grade operating temperature from −40 °C to +105 °C for robust operation in consumer appliance environments.

Typical Applications

• Home Appliances Control of refrigerators, washing machines, dryers and dishwashers—leveraging integrated timers, MPWM and ADC for motor control and sensing.
• Water Treatment & Pumps Pump and fan control with precise PWM generation and ADC-based feedback for flow and pressure sensing.
• Kitchen & Consumer Devices Appliance control for blenders and water purifiers, combining analog front-end and serial interfaces for user controls and sensors.

Unique Advantages

• Integrated motor-control peripherals: MPWM generator, multiple timers and ADC trigger sources enable compact motor-control designs with fewer external components.
• Flexible analog front end: 12-bit ADC, comparator and operational amplifiers simplify sensor interfacing and closed-loop control functions.
• Efficient processing: Cortex-M0+ at up to 80 MHz with a flash accelerator provides responsive execution while supporting moderate embedded workloads.
• Robust operating window: Wide supply voltage (2.7–5.5 V) and −40 to +105 °C temperature rating support deployment in typical home-appliance environments.
• Compact package: 32-LQFP surface-mount package (7 × 7 mm) balances board space and pin availability for midsize PCBs.
• Development and reliability support: DMA, CRC unit and SWD debug facilitate efficient data movement, integrity checking and streamlined development workflows.
