The DSC1033BI2-032.7680T is a MEMS-based XO (standard) from Microchip's PureSilicon™ series, delivering a 32.768 MHz CMOS output from a 3.3V rail.
Microchip lists the DSC1033BI2-032.7680T as obsolete.
The 4-SMD no-lead package measures 5.00 mm x 3.20 mm with a seated height of 0.90 mm max.
Microchip has not published an official direct replacement or pin-compatible second source for this DSC1033 series part. A functional replacement will require evaluating the frequency, supply voltage, package, and output type against current Microchip MEMS oscillator families such as the DSC1001 or DSC1121 series. Confirm pinout and footprint compatibility before committing a new BOM line.
Yes. The standby (power-down) function disables the output and drops the supply current to 1 µA max. The oscillator restarts with a clean CMOS output when the standby pin is de-asserted. This is useful for battery-powered designs that need to conserve power during idle periods.
