SX20AC/SX28AC
Configurable Communications Controllers with EE/Flash Program Memory, In-System Programming Capability and On-Chip Debug
1.0 PRODUCT OVERVIEW
1.1. 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.
