PROBLEM TO BE SOLVED: To provide a circuit device capable of changing an interface system used when communication with a control device is performed, and further to provide a physical quantity detection device, an electronic apparatus and a movable body.SOLUTION: A circuit device 20 includes: an interface section 144 capable of switching an interface processing system to a first interface system through an n-th interface system (n is an integer of 2 or more); a nonvolatile memory 146; and a sequence execution circuit 141 executing control sequence of the nonvolatile memory 146. Further, the sequence execution circuit 141 executes sequence which writes designation information of an i-th interface system (i is an integer satisfying 1≤i≤n) into the nonvolatile memory 146 when receiving a command designating the i-th interface system out of the first interface system through the n-th interface system via the interface section 144.SELECTED DRAWING: Figure 1 |
