STMicroelectronics has introduced the EMIF06-MSD03F3, an IC combining EMI filtering and ESD protection for mobile phones, tablets and 3G dongles using SD 3.0 UHS-I (ultra high speed) micro-SD cards. The IC protects micro-SD interfaces up to the specified UHS-I speed of 104Mbyte/s. The company says that the IC features a miniaturised package technology and allows either electrical or mechanical card-insertion detection. The IC also has integrated pull-up resistors which ensure system behaviour when no card is inserted and an EMI filter to block GSM interference. The IC features ±15kV ESD protection meeting IEC 61000-4-2, protection for all SD card data and power lines, 7pF maximum load capacitance, 16-bump, 0.4mm pitch wafer-level chip-scale package, 1.54x1.54mm outline.
