The Parallax RoHS Compliant SX20AC/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 SX20AC/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.
Due to the package type and price, the SX20AC/SS-G is a popular production chip needing fewer I/O pins. The SX20AC/SS-G has the following characteristics:
- Microcontroller: SX20AC/SS-G
- Package type: 20-pin SSOP
- Speed: Up to 75MIPS
- Pins: 20
- I/O: 12
- 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 SX20AC/SS-G is normally between 6,000 and 15,000 units.
