Housed in a 4-VDFN with exposed pad — 7.00 mm x 5.00 mm body, 0.90 mm seated height. The exposed paddle on the bottom is the thermal path; the datasheet layout shows a via-stitched ground pad under the part to pull heat into the PCB plane. Surface-mount only — no through-hole variant. The VDFN package reflows with a standard lead-free profile; the exposed pad wets well if the solder paste aperture covers at least 50% of the pad area.","metaTitle":"DSC1505AI3A-8M000000 MEMS XO – 8 MHz, LVCMOS, ±20 ppm","metaDescription":"Microchip DSC1505AI3A-8M000000 – 8 MHz MEMS oscillator, LVCMOS output, ±20 ppm stability, -40 to 85 °C, standby function.

The MEMS base resonator eliminates the quartz cold-start delay and is more resistant to vibration and shock. No external load capacitors are needed."},{"question":"How do I use the standby (power-down) function on DSC1505AI3A-8M000000?","answer":"The standby pin (typically pin 1 on the 4-VDFN) is active-low — pulling it to GND puts the oscillator into power-down mode, drawing 1 µA typ and disabling the output. Releasing the pin or driving it high restarts the MEMS drive and output within a few milliseconds. No external pull-up is needed if the driving logic has a push-pull output."},{"question":"Is DSC1505AI3A-8M000000 compatible with 1.8V systems?","answer":"Yes — the supply voltage is 1.8V, and the LVCMOS output swings rail-to-rail, so it drives 1.8V logic inputs directly without a level shifter. The input threshold is compatible with 1.8V CMOS levels."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1505AI3A-8M000000","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1505AI3A-8M000000 when reusing this data.
