Thermal Management, Real-Time Clock Battery | Emerson MVME2500

Functional Description

4.17.1 Reset Sequence

The timing of the reset sequence supports each chip reset requirements with respect to the power supply.

4.18Thermal Management

The MVME2500 utilizes two on-board temperature sensors: one for the board and the other for the CPU temperature sensor. The board temperature sensor is located near the dual RJ45 connector near the front panel. The CPU temperature sensor is located near the P2020 CPU.

The MVME2500 thermal management support will interrupt the process only to show the current board and CPU temperature. This interrupt is routed directly to one of the processor’s IRQ4.

The table below shows the low and high threshold temperature in order for the interrupt to be asserted.

Table 4-2 Thermal Interrupt Threshold

		Board		CPU Temperature
		Temperature Limit		Limit

Board Variant	Board Temperature Limit	Low	High	Low	High

Standard Variant	0°C to +55°C	0°C	70°C	0°C	90°C

Extended Temperature	-55°C to +71°C	-40°C	90°C	-40°C	100°C
Variant

4.19Real-Time Clock Battery

A back-up battery based on the CR2325 specification is provided. It helps support the RTC hold-up requirements that maintain the correct date and time for at least two hours after the backplane power is switched off.
