Description
The damage tests of microprocessors were carried out under γ-rays. The PIC microprocessors produced by Microchip Technology Inc are inexpensive and popular CPU. so that they are used in autonomous small robots.Under γ-rays,we tested the reliability of the PIC12F675 and PIC16F84A that belonged to mid-renge of the 8-bit PIC microprocessor's family. The source of γ-rays was Cesium 137.The source of γ-rays was mounted on the PIC directly.The PIC's plastic package was scraped by 0.7 mm in order to increase the exposure dose of the γ-rays to silicon chip in the plastic package of PIC. The LEDs connected to I/O Ports of the PIC were blinked by programs,Which was monitored by video camera.Seven days radiation ofγ-rays did not affect the function of PIC microproccssors.
