PCM-4825
486 SBC with Processor, Audio and VGA/LCD

PCM-4825 Introduction

The Biscuit PC family from Advantech is the ultimate cost-effective solution for limited space applications. These small all-in-one computers are the same size as a 3.5" hard disk drive and perform all the functions of an industrial computer and more!

All-in-one with Audio and VGA/LCD
The PCM-4825 and PCM-4825L Biscuit PCs are ultra-compact single board computers that integrate a 16-bit audio controller (PCM-4825 only) and 32-bit SVGA and LCD interfaces for a complete processing system. On-board features include a 5x86-133 embedded microprocessor, floppy disk controller, parallel port, an EDO DRAM SIMM socket, enhanced IDE, keyboard/mouse connector, and two standard serial ports. As energy efficient as it is space efficient, the PCM-4825/25L also supports power saving modes for I/O peripheral devices.

Maximum flexibility and compatibility
The PCM-4825 and PCM-4825L Biscuit PC is built especially for limited space embedded applications. Based on PC/AT architecture, it is compatible with most off-the-shelf software. In addition, because of the availability of inexpensive PC platforms, using the PCM-4825 or PCM-4825L can significantly reduce development time and cost. Moreover, mechanical configuration and system expansions are simple with industry standard PC/104 carrier modules.
