Device for controlling the operation of a radiocommunication electronic module, and corresponding electronic circuit

摘要

A device is provided for controlling operation of a radiocommunication electronic module using a control signal. The device includes a circuit for switching the control signal between a high logic state and a low logic state or vice versa, and a circuit for controlling the switching circuit. The control circuit generates a control signal. The module includes an activation input receiving the control signal. The control circuit includes: a first input receiving a first signal representative of a supply voltage; and a second input receiving a second signal from the module.

1. A device for controlling operation of a radiocommunication electronic module by a control signal, said device comprising:
a switching circuit having a control output for controlling the operation of the radiocommunication module and having a command input, wherein the switching circuit is configured to generate the control signal on the control output and switch a logic state of the control signal, from a logic high state to a logic low state or from the logic low state to the logic high state, once for each command signal received on the command input, and wherein said switching circuit is configured to maintain said control signal in its current logic state between successive command signals received on the command input; and a command circuit comprising: a first input receiving a first pulse representative of a change of state of a supply voltage; a second input receiving a second pulse coming from said module; and a command output coupled to the command input of the switching circuit, wherein the command circuit is configured to generate the command signal on the command output once for each pulse received on the first or second inputs to the command circuit; and means for generating the first pulse in response to the supply voltage switching from an inactive state to an active state.
