The 386Ex is a high- performance, 32-bit, single-chip microcomputer that is capable of protected-mode operation and includes an extensive array of integrated peripherals. The Flashlite 386Ex, like all members of the JK microsystems family of controllers, comes pre-loaded with DOS and utilities so that you can begin development right away. By connecting one of the Flashlite 386Ex serial ports to your PC and running a telecommunications program, you can immediately upload and execute programs compiled for a PC. The serial ports, counter/timers, interrupt controller, and speaker port on the Flashlite 386Ex are fully compatible with the IBM PC at both the hardware and software levels. Additional features such as the RS-485 serial port capability, battery-backed RAM and clock/calendar make the Flashlite 386Ex ideal for embedded controller applications. Peripheral boards are also available to add serial ports, A/D, D/A, high current drivers, relays and isolated I/O for many data acquisition and control applications. The Flashlite 386Ex Development Kit (99-0012) includes Flashlite 386Ex single board computer, Programming Cable, Connector Kit, 110Vin AC Adapter, Setup Guide, Schematic and CD with Borland C/C++ V4.52 Compiler, utilities, sample programs and documentation. (220Vin Development Kit 99- 0013 available.)
