The DSC6001MI1B-032K768 is a 32.768 kHz MEMS-based XO from Microchip's DSC60XXB series, delivering a standard CMOS output in a 2.0 mm x 1.6 mm 4-VFLGA package. The operating temperature range of -40°C to 85°C covers the industrial and automotive cabin envelope, but not the full -40°C to 125°C under-hood band — budget derating if the ambient exceeds 85°C.
Supply voltage flexibility and current draw
The 1.71V to 3.63V supply range lets this oscillator run directly from a 1.8V, 2.5V, or 3.3V rail — no external LDO needed, which saves a component on the BOM and reduces board area.
Frequency stability and Enable/Disable function
Frequency stability is ±50 ppm, which holds the 32.768 kHz output within ±1.6 Hz across the full temperature range — adequate for RTC timing and low-frequency reference applications.
