XHSC HC32L196KCTA-LQFP64

The HC32L190/HC32L196 series is an ultra-low-power, wide-voltage MCU designed to extend battery life in portable measurement systems. It integrates a 12-bit 1Msps high-precision SAR ADC, one 12-bit DAC, comparators, op-amps, built-in high-performance PWM timers, LCD display, and rich communication peripherals including multiple UART, SPI, and I2C interfaces. It also features built-in security modules such as AES and TRNG, offering high integration, strong noise immunity, high reliability, and ultra-low power consumption. The product is based on a Cortex-M0+ core, compatible with the industry-proven Keil & IAR development toolchains, and supports both C language and assembly language programming.
