CoreModule/386-II Ultra-compact PC/AT-compatible, stackable module Includes all PC/AT motherboard functions: - 25 MHz CMOS 386SX CPU - Up to 16M bytes onboard DRAM - 16-bit expansion bus Other built-in functions - Dual serial and parallel controller Bootable "Solid State Disk" Watchdog Timer Ultra compact PC/104 form-factor: 3.6 x 3.8 inches (90 x 96 mm) Low power consumption (3.5 watts) Stackable PC/104 expansion The CoreModule/386-II offers complete PC/AT compatibility in a compact, preconfigured module. Within just 14 square inches of space, the CoreModule/386-II includes the equivalent functions of a PC/AT motherboard plus several additional expansion cards. Performance-critical embedded applications that formerly required chip-based custom designs can now benefit from an off-the-shelf module with the power of a 25 MHz 80386SX CPU, along with hardware and software standards like PC/AT and MS-DOS compatibility. The CoreModule/386-II is designed to meet the demands of embedded systems. through its extreme compactness, low power consumption. +5V-only operation, wide operating temperature range, and high reliability. *Configuration Flexibility* The CoreModule/386-II can be used as a macrocomponent, plugged into a proprietary application board, or it can be combined with Ampro's PC/104- compatible MiniModule expansion products to form compact, highly integrated control subsystems. Multiple modules can be stacked together without the cost and space penalties of additional mounting hardware, or they can be separately mounted on a custom circuit board. *Solid State Disk Reliability* One of the unique features of the CoreModule/386-II is its byte-wide memory device socket that is typically used as a Solid State Disk (SSD), substituting EPROM, Flash EPROM, or nonvolatile RAM (NOVRAM) memory devices for conventional disk drives. Using Ampro's SSD Support Software, any DOS-based-softwareincluding the operating system, programming languages, drivers, and application programscan easily be run from SSD without modification. *Enhanced BIOS* Another very important feature of the CoreModule/386-II is its inclusion of enhanced BIOS services and functions that meet the unique requirements of embedded microcomputer system applications. A partial list of these BIOS enhancements appears in the specifications section of this data sheet.
