32-Bit Arm® Cortex®-M3 MCU
HT32F12364
General Description
1
The Holtek HT32F12364 device is a high performance, low power consumption 32-bit microcontroller
based around an Arm® Cortex®-M3 processor core. The Cortex®-M3 is a next-generation processor
core which is tightly coupled with Nested Vectored Interrupt Controller (NVIC), SysTick timer,
and includes advanced debug support.
The device operates at a frequency of up to 72 MHz with a Flash accelerator to obtain maximum
efficiency. It provides 256 KB of embedded Flash memory for code/data storage and 128 KB
of embedded SRAM memory for system operation and application program usage. A variety
of peripherals, such as ADC, I2C, USART, UART, SPI, SCI, PDMA, GPTM, PWM, SCTM,
EBI, CRC-16/32, AES-128/256, USB2.0 FS and 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 above features ensure that the device is suitable for use in a wide range of applications,
especially in areas such as white goods application control, power monitors, alarm systems,
consumer products, handheld equipment, data logging applications, motor control, fingerprint
recognition, smart door lock and so on.
