Abstract: The integrated circuit chip programming apparatus comprises a fixing device, an actuating device and a flexible device. The fixing device comprises a supporting part and a cover. One end of the cover is coupled with one end of the supporting part and comprises an accommodation space for accommodating a chip therein. The cover selectively covers or uncovers the supporting part so as to close or expose the accommodation space. The flexible device is coupled between the fixing device and the actuating device. When a force is against the forced end, the actuating device is rotated to drive the cover to expose the accommodation space. When no force is against the forced end or the force against the forced end is stopped, the flexible device provides a recovery force to allow the actuating device to rotate to drive the cover to close the accommodation space of the supporting part.
Abstract: Disclosed is an isolation-free in-circuit programming system including an in-circuit programmer and an application board connected to the in-circuit programmer through a peripheral interface bus and having a bus controller and a memory, wherein the bus controller is connected to the memory through a system bus, in which the in-circuit programmer includes a leakage current discharging circuit connected to the bus controller for detouring a leakage current flowing from the memory or the in-circuit programmer to the bus controller to flow therethrough. The in-circuit programmer also includes an input level shifter for receiving data signals from the memory and adjusting the high-level input voltage of the in-circuit programmer to decode any weak high-level output voltage from the memory, thereby allowing the high-level output voltage of the memory to be higher than the high-level input voltage of the in-circuit programmer.
