Processor/power management subsystem
Overview
The main processor/power management PCB contains the electrical
hardware to provide data processing and display of patient and monitor
configuration data, communication and interface circuitry, and power
conversion and battery management functions for the patient monitor.
The high level of integration attained in the design of the processor/
power management PCB is attributed to the use of several highly
integrated devices. A complex communications controller, ASIC, and
battery management hardware significantly improve the performance
and reduce the complexity and cost of the assembly. In addition to the
CPU, the main microcontroller contains a six-channel communications
processor as well as memory, compact flash wireless card, and video
controllers. The devices used in the core processing architecture all
operate at 3.3 V to minimize power consumption, yet the main processor
and ASIC are tolerant of 5 V hardware peripherals.
