丨Product Introduction丨
Holtek has launched a new Arm® Cortex®-M4 32-bit USB OTG microcontrollerHT32F49041 designed for high-performance computing and USB application scenarios, utilizing the efficient Cortex®-M4 core. This core implements a complete set of DSP instructions and a Memory Protection Unit (MPU), enhancing numerical computation performance and application security. The microcontroller features multiple power-saving modes, making it particularly suitable for various application scenarios such as embedded systems, computer peripherals, industrial automation, motor control, the Internet of Things, and consumer electronics, providing a cost-effective entry-level option for Cortex®-M4 core USB OTG applications.
HT32F49041 can operate at a maximum speed of 96MHz, with a voltage range of 2.4V to 3.6V, and is compliant with an industrial temperature range of -40℃ to 105℃. Key resources include 64KB of Flash memory, 20KB of SRAM, and a rich set of peripherals: such as a 12-bit 16-channel ADC with a sampling rate of up to 2Msps, 6 16-bit general-purpose timers, 1 32-bit general-purpose timer, 1 advanced timer, 2 basic timers, 2 I²C interfaces, 3 SPI/I²S interfaces, 4 USART interfaces, 1 IRTMR, 1 OTGFS (supporting Xtal-less operation in device mode), and 1 CAN interface. It is available in 20TSSOP, 32QFN, and 48/64LQFP packages, with up to 55 GPIO pins depending on the package type.
HT32F49041 provides complete development resources, including hardware development kits, peripheral driver function libraries (Firmware Library), and application examples, supporting Keil MDK and IAR EWARM development environments, and equipped with ISP/ICP production programming tools, offering an efficient and comprehensive development ecosystem that significantly shortens development and production time, enhancing product market competitiveness.
