Holtek HT32F59041_48LQFP

ARM Cortex-M0+, 20 MHz, 63 kB ROM, 8 kB RAM

The HOLTEK HT32F590xx device is a high performance, low power consumption 32-bit microcontroller based around an Arm Cortex-M0+ processor core. The Cortex-M0+ is a next-generation processor core which is tightly coupled with Nested Vectored Interrupt Controller (NVIC), SysTick timer, and including advanced debug support. The device operates at a frequency of up to 20 MHz with a Flash accelerator to obtain maximum efficiency. It provides 64 KB of embedded Flash memory for code/data storage and 8 KB of embedded SRAM memory for system operation and application program usage. A variety of peripherals, such as Hardware Divider DIV, ADC, I 2 C, USART, UART, SPI, MCTM, GPTM, PWM, BFTM, CRC-16/32, RTC, WDT, SW-DP (Serial Wire Debug Port), etc., are also implemented in the device. Several power saving modes provide the flexibility for maximum optimization between wakeup latency and power consumption, an especially important consideration in low power applications. The device also contains a multi-channel 24-bit Delta Sigma A/D converter which includes a programmable gain amplifier and is designed for applications that interface differentially to analog signals. The above features ensure that the device is suitable for use in a wide range of applications, especially in areas such as white goods application controllers, power monitors, alarm systems, consumer products, handheld equipment, data logging applications, motor controllers and so on.
