Small-sized and multifunctional MINI CPU module specification

Abstract

The invention discloses a small-sized and multifunctional MINI CPU module specification. A bus pin definition and signal description of the small-sized and multifunctional MINI CPU module specification comprise a Video analog video signal, a VGA display signal, an HD Audio signal, an LVDS signal, an SATA signal, a USB 2.0 signal, a USB 3.0 signal, a PCI-e Bus signal, a Giga LAN signal, an SMBUS signal, a Serial signal, a GPIO signal, a DDI signal (which can be used along with the GPIO signal), an LPC Bus signal, a KB / MS / Other signal, an ATX signal, a Power standby signal, a Power signal, a GND signal and a reserved pin. A double-row surface-mounted 180 pin socket QSH-090-F-D-A-K produced by the SAMTEC company is selected as a bus connector. The size of the module is 85 * 65 mm. On the basis of the MINI CPU module specification, embedded computer modules of various performance classes can be developed, a system engineer can only focus on a design of an application system substrate, the computer system functions are changed just through redesign of the application system substrate, the computer system functions can be updated just through the utilization of latest computer modules, and developing time and cost are greatly saved.

Description

technical field [0001] The invention relates to an embedded computer module specification, in particular to a small size, multifunctional MINI CPU module specification. Background technique [0002] Common small-size embedded computer-on-module specifications include ETXexpress, COM Express, and so on. ETX has successfully solved some bottlenecks in the practical application of PC / 104, which was previously monopolized in the field of embedded computers, such as the cable-free design of the entire board, relatively higher computing performance, more abundant expansion interfaces, and good thermal performance. Design concepts and higher integration, etc., created the "chip PC era". But ETXexpress does not support Giga LAN, SATA signal, USB3.0 signal, PCI express signal technology, and the size is relatively large (114×95 mm). COM Express is designed to adapt to future technological development trends and market demands, incorporating emerging bus and interface technologies s...

AI Technical Summary

Problems solved by technology

COM Express is quite flexible in type, it has 4 optional sizes, three of which are 110×55 mm, 125×95 mm, 95×55 mm, the size is larger, and the other size is smaller (84× 55 mm), integrates a variety of traditional interfaces and popular high-speed interface signals, but does not support dual Giga LAN, USB3.0, VGA, VIDEO interface signals
