78M6613 Data Sheet

1.2.5 Temperature Sensor

The 78M6613 includes an on-chip temperature sensor implemented as a bandgap reference. It is used

to determine the die temperature. The MPU reads the temperature sensor output during alternate

multiplexer cycles. The primary use of the temperature data is to determine the magnitude of

compensation required to offset the thermal drift in the system (see Section 3.3 Temperature

Compensation).

1.2.6 Functional Description

The AFE functions as a data acquisition system, controlled by the MPU. The input signals (A0, A1, A2,

and A3) are sampled and the ADC counts obtained are stored in CE DRAM where they can be accessed

by the CE and, if necessary, by the MPU. Alternate multiplexer cycles are initiated less frequently by the

MPU to gather access to the slow temperature signal.
