Supply voltage spans 1.8V to 3.3V, so the same part serves 1.8V-core SoCs and 3.3V peripheral buses without a separate level translator. ## AEC-Q100 qualification and standby power-down Rated AEC-Q100, this oscillator is qualified for automotive-grade reliability — under-hood or chassis-domain ECUs that see -40°C cold starts and 85°C continuous soak are within its operating envelope. Active output current is 8.7 mA max at 133.333 MHz — the MEMS resonator draws less than a comparable quartz oscillator, which matters when the clock tree has multiple fan-outs. Housed in a 5.00 mm x 3.20 mm 4-SMD no-lead package (0.90 mm seated height), the footprint matches industry-standard 5x3.2 mm oscillator pads — a direct swap for quartz oscillators in the same form factor. Surface-mount on standard FR-4 with no special layout rules; the MEMS die is encapsulated and handles reflow profiles typical for lead-free soldering.","metaTitle":"DSC1001BI2-133.3330T MEMS Oscillator 133.333 MHz CMOS","metaDescription":"Microchip DSC1001BI2-133.3330T XO (Standard) MEMS oscillator, 133.333 MHz CMOS output, ±25ppm stability, -40°C to 85°C, AEC-Q100.

The 4-SMD no-lead package matches the standard 5.0 mm x 3.2 mm quartz oscillator footprint, so no board layout change is needed. The MEMS version offers better shock and vibration tolerance than quartz."},{"question":"What is the standby (power-down) function and how is it controlled?","answer":"The standby function (labeled Power Down in the datasheet) disables the output and reduces supply current to 15 µA max. It is controlled via the enable pin — pulling the pin low puts the oscillator into standby; pulling it high or leaving it floating enables the output. This is useful for battery-powered or duty-cycled systems."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1001BI2-133.3330T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1001BI2-133.3330T when reusing this data.
