HC32F176KATA-LQ64

The HC32F170/HC32F176 series is a general-purpose MCU with a wide operating voltage range. It integrates a 12-bit 1Msps high-precision SAR ADC, one 12-bit DAC, along with comparators, op-amps, built-in high-performance PWM timers, LCD display, and rich communication peripherals including multiple UART, SPI, and I2C interfaces. The device also incorporates security modules such as AES and TRNG, offering high integration, strong noise immunity, and high reliability. The product is based on a Cortex-M0+ core, supported by the industry-proven Keil & IAR development environments, with full support for C language, assembly language, and assembly instructions.
