The Parallax SX28AC/SS-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/SS-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/SS-G is the most popular SX chip for high-volume production products, with a low cost per I/O. The SX28AC/SS-G has the following characteristics:
- Microcontroller: SX28AC/SS-G
- Package type: 28-pin SSOP
- Speed: up to 75 MIPS
- Pins: 28
- I/O: 20
- EE/Flash: 2048 x 12
- RAM: 136 bytes
- Internal oscillator: 32 kHz to 4 MHz
Parallax is the only worldwide supplier of the SX chip, ensuring reliable supply, quality programming tools, technical support, and the lowest pricing. Parallax inventory of the SX28AC/SS-G is normally between 28,000 and 35,000 units.
