The 1T 8051 core executes most instructions in 1-2 clock cycles (vs 12 in classic 8051), achieving 22.1 MIPS at 22.1184MHz. The 2KB auxiliary RAM provides a second data memory space accessible via MOVX instructions, useful for larger buffers and data arrays. The 10-bit ADC supports 8 channels with conversion time of 3.3us at 22MHz. Two UARTs support independent serial communication channels. The SPI interface operates in master or slave mode at up to 10MHz. The PCA (Programmable Counter Array) provides 6 capture\/compare modules for PWM generation, pulse measurement, and timer functions. Four 16-bit timers (Timer0-2 and Timer3) support auto-reload, capture, and compare modes. The BOD (Brown-Out Detection) resets the MCU when VDD drops below 3.8V (selectable 4.0V\/3.8V\/2.7V\/2.2V). The internal RC oscillator is trimmed to 22.1184MHz +\/-1% at 25C, eliminating external crystal cost. The device also supports ICP (In-Circuit Programming) and AP (Application Programming) for firmware updates. The LQFP-48 package provides 40 I\/O pins.","pin_description":"
