SX20AC/SX28AC
Configurable munications 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 munications controllers is fabricated in an advanced CMOS process technology. The advanced process, bined with a RISC-like architecture, allows high-speed putation, 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 parator, 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.
