Cortex-M0+, 48 MHz
The HOLTEK HT32F6135X 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 48 MHz for HT32F6135X with a Flash accelerator to obtain maximum efficiency. It provides up to 128kB of embedded Flash memory for code/data storage and 16kB of embedded SRAM memory for system operation and application program usage. A variety of peripherals, such as ADC,2channel DAC, I2C, I2S USART, UART, SPI, QSPI, GPTM, SCTM, CRC-16/32, RTC, WDT, USB2.0 FS, 32 channel music synthesizer, 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 HT32F6135X integrates Wave Table synthesis function. It can operate up to 32 channels of Wave Table synthesis at one time and controls the Midi Engine to generate melody by setting the special registers. The Wave Table synthesis waveform is stored in external SPI Flash ROM for application flexibility. With these features, it provides enhanced functions and higher performance.
The above features ensure that the devices are suitable for use in a wide range of applications, especially in areas such as electronic organ, Digital piano, Electronic drum, electric guitar, electric accordion and so on.
Internal SPI data Flash ROM stores instrument timbre and Voice/Sound effect and other data.
