Product Description

The product ESK32-31401 is a starter kit for the 32-Bit Arm® Cortex®-M4 MCU, HT32F49395. It can help users get up, run and use the HT32F49395 in the shortest possible time frame.

High-Performance Arm® Cortex®-M4F 32-bit Microcontroller offering single-precision Floating Point Unit (FPU) that supports all Arm® single-precision data processing instructions and data types, advanced Industrial interfaces and Automotive temperature operating range. Extensive embedded memory makes this Microcontroller suitable for demanding Industrial, IOT, and Medical applications.


  • 240MHz Core with Floating Point Unit and DSP instructions
  • -40°C~105°C operating range
  • 2.6 V ~ 3.6 V operating range
  • Up to 1MB Flash and 224KB SRAM embedded memory
  • USB2.0 full-speed and 2 CAN Interfaces
  • 16-bit motor control, and 16/32-bit general-purpose timers
  • QFN48, LQFP48, LQFP64, LQFP100 packages

The HT32F49365/HT32F49395 devices are based on the high-performance Arm®Cortex®-M4 32-bit RISC core, operating at a frequency of up to 240 MHz. The Cortex®-M4 core features a Floating Point Unit (FPU) single precision which supports 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) which enhances application security.

The devices incorporate high-speed embedded memories (up to 1024 KBytes of internal Flash memory, 96 + 128 KBytes of SRAM), external SPI Flash (up to 16 MBytes addressing capability), and a wide range of enhanced GPIOs and peripherals connected to two APB buses. Any block of the embedded Flash memory can be protected by the “sLib” (security library), functioning as a security area with code-executable only.

The devices offer three 12-bit ADCs, two 12-bit DACs, eight general-purpose 16-bit timers plus two general-purpose 32-bit timers, and up to two PWM timers for motor control. They support standard and advanced communication interfaces including up to three I²Cs, four SPIs (all multiplexed as I²Ss), two SDIOs, eight USARTs/UARTs, an USBFS, and two CANs.

The HT32F49365/HT32F49395 devices operate in the -40 to +105 °C temperature range, from a 2.6 to 3.6 V power supply. A comprehensive set of power-saving modes allows the design of low-power applications.

The HT32F49365/HT32F49395 are supplied in different package types. The entire HT32F49365/ HT32F49395 series of devices are fully pin-to-pin, software and functionally compatible with each other, except that the configurations of peripherals are not completely identical, depending on the package types.
