SummaryHC32M140 series products are 32bit MCU based on ARM-Cortex M0+ developed by Huada Semiconductor. Compared with traditional CPU cores, they are more efficient and have lower power consumption. Wider operating voltage range, can support 3V and 5V systems at the same time. Integrate rich peripheral resources such as TIMER4, asynchronous serial port, SPI, I2C, 12-bit high-speed ADC, operational amplifier, voltage comparator, etc. This product is the first 5V voltage product of Huada Semiconductor on the M0+ platform. Typical applications  Motor control: UAV motor speed regulator, electric bicycle, variable frequency fan, range hood, air purifier, power tool; Compressor control: refrigerator compressor control.

In addition, any I/O port can be equipped with a port relocation function to configure the settings of peripheral functions. – Fast GPIO supports single-cycle access – Each port can be configured with a built-in pull-up resistor – Each port can be configured with an open-drain output – The port pin level can be read directly – Port relocation – Some pins support high current output 12 mA  Dual timer The dual timer consists of two programmable 32/16-bit down counters. The operating mode of the timer channel can be selected from the following modes. – Free-running mode – Periodic mode (= reload mode) – One-shot modeTIMER4 (1 unit) TIMER4 consists of the following modules: – Counter unit 1 channel – Comparison output unit 6 channels (2 channels x 3 units) – ADC start trigger unit 6 channels (1 channel x 6 units) – EMII emergency input unit 1 channel Motor control can be achieved using the following functions: – PWM signal output function – Dead-band timer function – A/D converter start function – EMII (motor emergency stop) interrupt functionExternal interrupt controller unit – External interrupt input pins: Up to 16 – Non-maskable interrupt (NMI) input pin: 1 Watchdog timer (2 channels) – When the timeout value is reached, the watchdog timer generates an interrupt or reset, – There are two types of watchdogs in this series: “hardware” watchdog and “software” watchdog. The “hardware” watchdog timer uses the internal low-speed RC oscillator and can therefore operate in any low-power mode except stop mode. Watch counter – The watch counter can wake up the system in low-power mode. – The clock source of the watch counter can come from any clock except the PLL clock. Clock/Reset – Clock Five clock sources are available (two external oscillators, two internal RC oscillators)  External high-speed OSC oscillator: 4MHz ~ 16 MHz  External low-speed OSC oscillator: 32.768 kHz  Internal high-speed RC oscillator: 4 MHz  Internal low-speed RC oscillator: 32 kHz  Internal PLL: up to 48MHz – Reset  RSTB pin reset  Power-on reset  Software reset  Watchdog timer reset  Low voltage detection reset  Clock monitor reset The clock monitor monitors the external clock for abnormalities based on the clock generated by the internal RC oscillator. – When an external oscillation clock failure (clock stop) is detected, a reset occurs – When an external frequency abnormality is detected, an interrupt or reset is valid  Low Voltage Detection (LVD) This series of products contains two low voltage detection units: LVD1 and LVD2, which are used to detect the DVCC voltage. The LVD detection threshold is adjustable. When the voltage is lower than the threshold voltage, an interrupt or reset can be generated according to the configuration.  Operational Amplifier – This series of products contains two operational amplifiers that can work independently SRAM Check – This series of products supports SRAM parity check function, and an interrupt can be generated when a parity error is detected.  Low Power Mode There are the following low power modes: – Sleep mode (Sleep) – Timer mode (Timer) – Stop mode (Stop)  Peripheral clock gating can reduce system power consumption by gating the operating clock of unused peripherals.  Debug interface – Serial Wire Debug Interface (SW-DP) – Micro Trace Buffer (MTB)  Unique ID Each chip has a fixed 80-bit unique ID.  Power supply – supports wide range voltage: DVCC = 2.7V ~ 5.5 V Brushless frequency conversion library files can be provided Sample request method: WeChat & mobile phone 18602160290 QQ772960647
