The XK2200 is equipped with a 32-bit ARM Cortex-M0 core, operating at a peak frequency of 48MHz. It integrates up to 64KB of FLASH and 6KB of SRAM, supports two 32-bit timers, and includes interfaces such as UART, I2C, and SPI. It also features a built-in hardware acceleration engine for cryptographic algorithms and has passed the EAL4+ and national second-level security certifications.
