HT32F49153/HT32F49163 Datasheet 32-bit Arm® Cortex®-M4 Microcontroller, up to 256 KB Flash and 48 KB SRAM with ADC, DAC, USART, SPI, I2S, I2C, GPTMR, ACTMR, BTMR, CRC, ERTC, WDT, WWDT, DMA, CAN, XMC, IRTMR and OTGFS Revision: V1.10 Date: October 10, 2025 1 General Description 32-bit Arm® Cortex®-M4 MCU HT32F49153/HT32F49163 1 General Description The HT32F49153/HT32F49163 devices are based on the high-performance Arm® Cortex®-M4 32-bit RISC core operating at a frequency of up to 150 MHz. The Cortex®-M4 core Features a Floating Point Unit (FPU) single precision supporting all Arm® single-precision data processing instructions and data types. It also implements a full set of DSP instructions and a Memory Protection Unit (MPU) that enhances application security. The devices incorporate high-speed on-chip memories, including up to 256 Kbytes of Flash memory, 48 Kbytes of SRAM, and 20 Kbytes of boot memory that can be used as a Bootloader or as a general instruction/data memory (one-time-configurable) to achieve the maximum of 256+20 Kbytes. Any block of the embedded Flash memory can be protected by the “s Lib” (security library), functioning as a security area with code-executable only. In addition, the devices include a highlevel memory extension: an external memory controller (XMC). The devices offer one 12-bit ADC, two 12-bit DACs, eight general-purpose 16-bit timers plus one general-purpose 32-bit timer, two basic timers, one advanced timer and one low-power ERTC. It also Features standard and advanced munication interfaces: up to three I2Cs, three SPIs (multiplexed as I2Ss), eight USARTs, two CANs, an OTGFS, and infrared transmitter. The devices operate in the -40 to +105 °C temperature range, from a 2.4 to 3.6 V power supply. A prehensive set of power-saving mode allows the design of low-power application. The devices are supplied in different package types. The entire HT32F49153/HT32F49163 series of devices are pin-to-pin, software and functionally...
