The DSC1001DL5-032.0000T is a 32 MHz MEMS-based XO from Microchip's DSC1001 series, delivering a CMOS output with ±10 ppm frequency stability across a -40°C to 105°C industrial temperature range. The MEMS resonator core offers better shock and vibration resistance than a quartz crystal — a real advantage in under-hood or factory-floor environments where mechanical stress can pull a quartz oscillator off frequency.
Operating from 1.8V to 3.3V, this oscillator can be powered directly from a 1.8V MCU rail or a 3.3V peripheral bus without a separate LDO — one less part on the BOM. Active current draw is 7.2 mA max at 32 MHz — low enough that the thermal impact in the 2.50 mm x 2.00 mm 4-SMD package is negligible, even in a cramped ECU layout.
Package, mounting, and production status
Housed in a 4-SMD, no-lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm, it is a standard surface-mount footprint that reflows on a standard profile without special handling.
