Direct power injection on functional and non-functional signals of SPI EEPROM memories
Abstract
This paper deals with the conducted immunity of SPI EEPROM memories. The design and implementation of a wideband radio frequency-baseband multiplexer are described. This multiplexer makes it possible to superimpose radio frequency noise to a functional baseband signal with controlled and repeatable transfer characteristics. The baseband path has a measured DC - 380MHz bandwidth, while the radio frequency path (up to 1W) has a 150kHz - 5GHz bandwidth. This multiplexer is used to compare the conducted immunity of functional and non-functional pins of EEPROM memories with a single measurement set-up.
