HK HK32F030MF4P6

The HK32F030M series is based on the ARM Cortex™-M0 core, operating at up to 32MHz, with 16K-Byte FLASH, 448-Byte EEPROM, and 2K-Byte SRAM. Through register configuration of the FLASH controller, interrupt vector remapping within the 16K-Byte address space is supported. All pins of the HK32F030M, except power and ground, can function as GPIO, peripheral I/O, or external interrupt inputs (TSSOP20 package supports 16 GPIOs), maximizing the number of available pin signals in pin-constrained applications. The HK32F030M integrates multiple communication interfaces: 1× high-speed USART (up to 6Mbps), 1× high-speed SPI/I2S (up to 18Mbps), and 1× high-speed I2C (up to 1MHz). USART supports synchronous and asynchronous full-duplex or half-duplex communication, multi-master communication, LIN protocol, SmartCard protocol, and IrDA SIR encoding/decoding; RX/TX pin positions are software-swappable, with data reception wake-up supported in MCU Stop mode. SPI/I2S supports full-duplex or half-duplex communication with 4~16-bit data length, master/slave mode, TI mode, NSS pulse mode, automatic CRC verification, and I2S protocol. I2C supports 1MHz/400kHz/100kHz transfer rates, master/slave mode, multi-master mode, 7/10-bit addressing, and SMBus protocol, with data reception wake-up supported in MCU Stop mode. The HK32F030M integrates 1× 16-bit advanced PWM timer (4 PWM output channels, 3 of which feature dead-time complementary output), 1× 16-bit general-purpose PWM timer (4 PWM output channels), and 1× 16-bit basic timer (timed CPU interrupt output). The HK32F030M incorporates analog circuitry: 1× 12-bit 1Msps ADC (8-bit effective resolution), 1× POR/PDR power-on/power-down reset circuit, and 1× internal reference voltage (sampled on-chip by the ADC). The HK32F030M supports a wide range of low-power modes and can be automatically woken up by the internal low-power timer in low-power mode. The HK32F030M operates over a temperature range of -40℃ to +85℃ with a supply voltage of 1.8V to 3.6V, meeting the requirements of most application environments.
