Hospital Bedside Monitor Machine GE Dash2500 patient monitor Mainboard Mother Board PWB 2023162-001

► Brief Introduction

The Main Board is configured with Flash ROM, EEPROM, RAM, Primary Processor, Secondary Processor, and NIBP. The Primary Processor operates from a 4.9152 MHz crystal stepped up to 49.152 MHz. The Primary Processor services and controls the RAM, Flash ROM, EEPROM, the PHiliphhilipysiological interface modular devices and display backlighting. The Secondary Processor monitors the power supply circuit and signals within the NIBP circuits, controls the power-on/off sequences, and performs watchdog tasks on it and the Primary Processor monitors. The Secondary Processor monitors the power supply circuit and controls the battery back up enable when no external sources are present and shuts down the unit when the battery is exhausted. It enables the battery charging circuit based on the battery charge status, unit power consumption, and the availability of an external power source.

The Random Access Memory (RAM) is composed of a SRAM chip and two SDRAM chips. The 512 Kbytes of battery-backed SRAM is provided to store trend data and to provide space for working algorithms and is accessed on bits D[0:15] of the data bus. The two 64-Mbit SDRAM chips are set up to form a 32-bit data bus on bits D[31:0] that is used for running the program and working memory. This gives 16 Mbytes of memory with an access time of less that 20 ns. The program is loaded (including the boot code) from the 16-bit FLASH Read Only Memory (ROM). The Electronically Erasable Programmable Read Only Memory (EEPROM) is an 8-bit chip that is used to store the calibration and other “setting” variables that have to be maintained in the event of a complete power failure.
