GENERAL DESCRIPTION
32-Bit Arm® Cortex®-M0+ BMS MCU HT32F61741 1 GENERAL DESCRIPTION
The device operates at a frequency of up to 20 MHz. It provides 64 KB of embedded Flash memory for code/data storage and 8 KB of embedded SRAM memory for system operation and application program usage. A variety of peripherals, such as Hardware Divider DIV, ADC, I2C, USART, UART, SPI, MCTM, GPTM, PWM, BFTM, CRC-16/32, RTC, WDT, SW-DP (Serial Wire Debug Port), etc., are also implemented in the device. Several power saving modes provide the flexibility for maximum optimization between wakeup latency and power consumption, an especially important consideration in low power applications. The device also has an individual cell voltage monitor module, a high accuracy voltage regulator, two discharge N-type MOSFET gate drivers and a charge N-type MOSFET gate driver, which is suitable for 3 to 8 rechargeable lithium batteries. The cell voltage monitor is designed to monitor each battery cell voltage individually and outputs the divide-by-2 voltage to the analog multiplexer with ±7.5 mV accuracy when analog output is 2.1 V.
