The DSC1001CI5-032.7680 is a MEMS-based XO (Standard) oscillator from Microchip's DSC1001 series, delivering a 32.768 MHz CMOS output with ±10 ppm frequency stability.
This is the sleep-state current — low enough that a battery-backed ECU or telematics module can sit parked for months without draining the reserve cell. Full 7.2 mA active draw resumes within the startup time of the MEMS resonator.
The oscillator operates across a 1.8V to 3.3V supply range, matching 1.8V core logic, 2.5V I/O, and 3.3V peripheral rails without an external level shifter.
Industrial temperature range and 4-SMD package
The 4-SMD, no-lead package (3.20 mm x 2.50 mm x 0.90 mm) is a standard 4-pin footprint — reflow solder profile follows the standard JEDEC MSL-1 for MEMS oscillators. No via-in-pad required; two-layer breakout is sufficient.
