Introduction SX-DEV development system offers friendly an easy to use complete development environment for Scenix microcontrollers. he SX-DEV development system supports all currently available SX microcontrollers from Scenix Semiconductor, include SX18/20/28A& and SX48/52BD. It uses the SX chip·s built-in debugging capabilities to provide a low-cost and efficient real-time emulation solution. It supports real-time debugging for all SX chips at any user-defined speed up to 100 MHz. It allows users to run the target application in real time, step-by-step or in animate mode, debug source codes and program a target SX device when design is complete. It connects to the serial port of any P& and comes with complete integrated development environment. Debugging and programming with SX-DEV is provided via a 6-pin emulation connector which mates with a 6- pin 0.1-inch square post header in the target system. The connector is wired for OS&1, OS&2, VDD, VSS and Reset pins, another one pin used as key. The oscillator circuit components on the target board should not be disconnected as long as the components are within recommended specifications. Features Real time, full speed execution Serial port interface Powered from the target device, less than 5 mA Voltage range from 3.0V till 5.6 V Source level support includes SASM, MPASM, Bytecraft SX&, Hitech PI& & and more Built-in in-system programmer User-selectable frequency source (quartz, generator, resonator, external source) up to 100 MHz Step, Run, Run to &ursor, Animate and Break functions Writes to all registers for code testing &hapter T
