An integrated temperature sensor device has a temperature sensor providing an analog signal corresponding to an ambient temperature, an analog-to-digital converter coupled to the sensor conditioning circuit and receiving the analog temperature signal, and a timer and control circuit which is operable to be configured to control the temperature sensor device to perform a sequence of temperature measurements and shut-down time periods, wherein multiple temperature measurements are taken during the measurement period, wherein the timer and control circuit is further operable to be programmed to set the number of temperature measurements and the length of the shut-down period.

An integrated circuit device may have an internal oscillator for generating a system clock, a trimming logic with a trimming register for adjusting an oscillation frequency of the internal oscillator; a serial data receiver, wherein a serial data stream includes a synchronization signal. The synchronization signal is operable to indicate that the system clock correct, too fast or too slow. The device may further have a circuit for decoding the synchronization signal operable to re-adjust a value stored in the trimming register upon evaluation of the synchronization signal.

Method and apparatus for clock recovery

High voltage rated isolation capacitors of inductors are formed on a face of a primary integrated circuit die. The isolation capacitors or inductors AC couple the primary integrated circuit in a first voltage domain to a second integrated circuit in a second voltage domain. The isolation capacitors or inductors DC isolate the primary integrated circuit from the second integrated circuit die. Isolated power transfer from the first voltage domain to the second voltage domain is provided through the high voltage rated isolation capacitors or inductors with an AC oscillator or PWM generator. The AC oscillator voltage amplitude may be increased for an increase in power through the high voltage rated isolation capacitors or inductors.

Unique addresses for a plurality of devices may be programmed through a single external connection (pin) on each device by using a one of a plurality of different analog voltage or current values on the single external pin in combination with a serial clock of a serial data bus for each device requiring a unique binary address. The unique binary address is stored in the device after detection of certain number of clocks on the serial data bus. Once the unique binary address has been stored in the device, the single external connection may be used for another purpose such as a multifunction external connection. This unique binary address may be retained by the device until a power-on-reset (POR) or general reset condition occurs. Address detection and address load commands on the serial bus may also perform the same address definition and storage functions.
