Introduction
The Parallax SX family of configurable communications controllers is fabricated in an advanced CMOS process technology.
The advanced process, combined with a RISC-like architecture, allows high-speed computation, flexible I/O control, and efficient data manipulation.
Throughput is enhanced by operating the device at frequencies up to 75 MHz and by optimizing the instruction set to include mostly single-cycle instructions.
The deterministic architecture of the SX provides reliable performance for time-critical applications.
In addition,
the SX architecture is flash-based and therefore reprogrammable.
On-chip functions include a generalpurpose 8-bit timer with prescaler, an analog comparator, a brown-out detector, a watchdog timer, a power-save mode with multi-source wakeup capability, an internal R/C oscillator, user-selectable clock modes, and highcurrent outputs.
These features enable the SX to be used as a general-purpose, high-speed microcontroller in a variety of applications.
