Meet Holtek's HT32F49365 & HT32F49395: The Cortex-M4F MCUs Redefining Efficiency

Holtek Corex M4 MCU HT32F49365 HT32F49395

Introducing Holtek's HT32F49365 and HT32F49395 MCU

In the world of embedded electronics, the right microcontroller can make all the difference in your project's success. Today, I'm excited to introduce you to Holtek's HT32F49365 and HT32F49395 Cortex-M4F microcontrollers (MCUs). These devices are not just any ordinary microcontrollers; they are a blend of high performance, versatility, and efficiency, making them ideal for a range of applications, especially those demanding increased computing capabilities.

Core Specifications and Performance

At the heart of these MCUs is the high-performance Arm® Cortex®-M4 32-bit RISC core, capable of operating at a frequency of up to 240 MHz. This core includes a Floating Point Unit (FPU) single precision, supporting all Arm® single-precision data processing instructions and data types. Moreover, they come equipped with a full set of DSP instructions and a Memory Protection Unit (MPU), enhancing application security.

Memory and Storage

These devices boast high-speed embedded memories, with up to 1024 KBytes of internal Flash memory and 96 + 128 KBytes of SRAM. For external storage needs, they support external SPI Flash with up to 16 MBytes addressing capability. Any block of the embedded Flash memory can be protected by the “sLib” (security library), providing an extra layer of security.

Input/Output and Peripheral Support

The HT32F49365 and HT32F49395 offer a comprehensive range of I/O options and peripheral support. They feature three 12-bit ADCs, two 12-bit DACs, and a variety of timers (including eight general-purpose 16-bit timers and two general-purpose 32-bit timers). For motor control applications, they provide up to two PWM timers.

Their communication interface support is equally impressive, with up to three I2Cs, four SPIs (all multiplexed as I2Ss), two SDIOs, eight USARTs/UARTs, an USBFS, and two CANs. This range of options opens up a plethora of possibilities for designers and engineers.

Robustness and Versatility

Designed to operate in a wide temperature range from -40 to +105 °C and a power supply range of 2.6 to 3.6 V, these MCUs are built for robust performance in diverse environments. They also include a comprehensive set of power-saving modes, allowing for the design of low-power applications.

Packaging and Compatibility

Holtek offers these MCUs in various package types, including a space-saving 6mm x 6mm QFN48 and LQFP packages of 48 (7mm x 7mm), 64 (10mm x 10mm), and 100 pin (14mm x 14mm). Importantly, the entire HT32F49365/HT32F49395 series of devices are fully pin-to-pin, software, and functionally compatible with each other, although the configurations of peripherals vary depending on the package types.

Low Power Modes

These MCUs support various low-power modes like Sleep, Deepsleep, and Standby, crucial for power-sensitive applications.

Boot Modes

Multiple boot modes, including boot from internal Flash, boot code area, and embedded SRAM, offer flexibility for different application requirements.

Development Tools and Resources

For developers, these MCUs are supported by the Keil MDK and IAR EWARM development environments. Holtek provides comprehensive development resources, including hardware development kits, peripheral driver firmware libraries, and application notes, with more being released.

Ideal Applications

With their combination of high-speed processing, extensive memory and peripheral support, and robust design, the HT32F49365 and HT32F49395 are ideal for a wide range of applications. These include industrial control systems, smart home devices, embedded systems, motor control, and more.
