HT32F61630 Datasheet 32-Bit Arm® Cortex®-M0+ Li-Battery Protection Microcontroller, up to 32 KB Flash and 2 KB SRAM with 500 ksps ADC, UART, SPI, I2C, SCTM, BFTM, LEDC, RTC and WDT Revision: V1.00 Date: April 27, 2023 1 General Description 32-Bit Arm® Cortex®-M0+ Li-Battery Protection MCU HT32F61630 1 General Description The Holtek HT32F61630 device is a high performance, low power consumption 32-bit microcontroller based around an Arm® Cortex®-M0+ processor core. The Cortex®-M0+ is a next-generation processor core which is tightly coupled with Nested Vectored Interrupt Controller (NVIC), Sys Tick timer and including advanced debug support. The device operates at a frequency of up to 16 MHz to obtain maximum efficiency. It provides up to 32 KB of embedded Flash memory for code/data storage and 2 KB of embedded SRAM memory for system operation and application program usage. A variety of peripherals, such as ADC, I2C, UART, SPI, SCTM, BFTM, LEDC, RTC, WDT and 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 includes an accumulative cell voltage monitor, a high accuracy voltage regulator, two discharge N-type MOSFET gate-drivers and a charge N-type MOSFET gate-driver which are provided for 3 to 8 cell Li-ion rechargeable battery applications. The accumulative cell voltage monitor is used to monitor an accumulative voltage from 1 to N and output the divide-by-N voltage to the analog multiplexer with a ±0.5 % divided ratio accuracy which can then be connected the VOUT pin to the one of the integrated A/D converter channel for measurement. The device can directly drive external power N-type MOSFETs to control charge and discharge by charge and discharge gate-drivers. The integrated battery balance circuitry provides a cell balance current...
