Title: Interface protective circuit in microprocessor system
Inventor: YAMAMOTO KUNIO
IPC: G06F15/78
Filed: 1992-02-26
Abstract: PURPOSE:To carelessly prevent making access to an interface by providing a protective circuit which receives a password from a microprocessor and then sets the interface in an enable state. CONSTITUTION:When a microprocessor 1 desires to make access to the interface 2, a first password is sent to a protective circuit 10 and the address of a first ROM 11 is decided based on the data on the password. This operation is repeated by the number of passwords. Then an enable signal is applied to the interface 2 for the first time only when all passwords are inputted to the ROM 11 in turn. Thus the interface 2 can work to receive the data from the microprocessor 1. In such a manner, the password is positively given to the circuit 10 and the interface 2 becomes available through the circuit 10. Then the microprocessor 1 can make access to the interface 2, therefore the erroneous accesses caused by the malfunctions of the microprocessor 1 can be prevented.

Abstract: PURPOSE:To insulate electrically the output transistor of an isolator from an output transistor controlling part, by using a DC/DC converter for a control power source which supplies electric power to a pin photodiode and the output transistor. CONSTITUTION:Light emitting LED11 turns of when input (a)10 to inverter 7 is at the high level and turns off when at the low level. The output light of LED11 is photodetected by pin photodiode 12. Then, a current flows to the base of output transistor TR13 of the isolator to turn on TR13.
