HT32F53252 48LQFP

Description

The Holtek HT32F53231/HT32F53241/HT32F53242/HT32F53252 devices are high performance,
low power consumption 32-bit microcontrollers 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 devices operate at a frequency of up to 60 MHz with a Flash accelerator to obtain maximum
efficiency. It provides up to 128 KB of embedded Flash memory for code/data storage and up to 16
KB of embedded SRAM memory for system operation and application program usage. A variety
of peripherals, such as Hardware Divider DIV, PDMA, ADC, I2
C, UART, USART, SPI, MCTM,
CMP, GPTM, PWM, BFTM, LEDC, EBI, CAN, CRC-16/32, 96-bit Unique ID, RTC, WDT, SWDP (Serial Wire Debug Port), etc., are also implemented in the devices. 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 above features ensure that the devices are suitable for use in a wide range of applications,
especially in areas such as consumer products, handheld equipment, automotive, industrial
automation control, battery management system, electronic equipment and so on.

Core
▆ 32-bit Arm® Cortex®-M0+ processor core
▆ Up to 60 MHz operating frequency
▆ Single-cycle multiplication
▆ Integrated Nested Vectored Interrupt Controller (NVIC)
▆ 24-bit SysTick timer
The Cortex®-M0+ processor is a very low gate count, highly energy efficient processor that is
intended for microcontroller and deeply embedded applications that require an area optimized,
low-power processor. The processor is based on the ARMv6-M architecture and supports Thumb®
instruction sets, single-cycle I/O ports, hardware multiplier and low latency interrupt respond time.
