XHSC HC32F196MCTA-LQFP80

The HC32F190/HC32F196 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, a built-in high-performance PWM timer, LCD display, and rich communication peripherals including multiple UART, SPI, and I2C interfaces. The series also incorporates information security modules such as AES and TRNG, featuring high integration, strong noise immunity, and high reliability. The core is based on the Cortex-M0+ architecture, compatible with the mature Keil & IAR development and debugging toolchains, supporting both C and assembly languages.
