HT32F67741 Datasheet 32-Bit Arm® Cortex®-M0+ BT5.2 BLE Microcontroller, up to 64 KB Flash and 8 KB SRAM with 1 Msps ADC, USART, UART, SPI, I2C, MCTM, GPTM, SCTM, BFTM, CRC, RTC, WDT Revision: V1.20 Date: September 26, 2024 32-Bit Arm® Cortex®-M0+ BT5.2 BLE MCU HT32F67741 1 General Description The Holtek HT32F67741 device is a high performance, low power consumption 32-bit microcontroller based around an Arm® Cortex®-M0+ processor core. The Cortex®-M0+ is a nextgeneration 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 40 MHz with a Flash accelerator to obtain maximum efficiency. It provides up to 64 KB of embedded Flash memory for code/data storage and up to 8 KB of embedded SRAM memory for system operation and application program usage. A variety of peripherals, such as Bluetooth Low Energy 5.2 controller, SPI, USART, UART, I2C, MCTM, GPTM, SCTM, BFTM, ADC, CRC-16/32, 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 wake-up latency and power consumption, an especially important consideration in low power applications. The above Features ensure that the device is suitable for use in a wide range of BLE products such as health care products, home appliances, smart device information beacons, data loggers, human interface device service, etc. 1 General Description Rev. 1.20 6 of 38 September 26, 2024 2 Features 32-Bit Arm® Cortex®-M0+ BT5.2 BLE MCU HT32F67741 2 Features Core ▆ 32-bit Arm® Cortex®-M0+ processor core ▆ Up to 40 MHz operating frequency ▆ 0.93 DMIPS/MHz - Dhrystone v2.1 ▆ Single-cycle multiplication ▆ Integrated Nested Vectored Interrupt Controller (NVIC) ▆ 24-bit Sys Tick timer The Cortex®-M0+ processor is a very low gate count, highly energy efficient processor that is intended for...
