The Parallax SX28AC/DP-G is a RISC architecture, high-speed microcontroller with flash program memory, in-system programming and debugging capability. Operating at frequencies up to 75 MHz with an optimized single-cycle instruction set, developers can implement real-time functions as software modules. Common examples include communication interfaces (I2C, SPI, UARTs), frequency generation and measurement, PWM, and sigma-delta A/D.
The on-chip functions of the SX28AC/DP-G include a general-purpose 8-bit timer, an analog comparator, watchdog timer, a power-save mode with wakeup capability, a configurable internal oscillator and high-current outputs.
The SX28AC/DP-G is the most popular SX chip for high-volume production products, with a low cost per I/O.
