Product details

66 MHz MEMS oscillator with ±50ppm stability

The DSC1033DE1-066.0000: Typical supply current is 4 mA max, dropping to 1 µA in standby (power-down) mode — a meaningful power savings for battery-powered or duty-cycled systems where the clock tree can be disabled between active periods.

Microchip lists the DSC1033DE1-066.0000 as Active.

3.3V supply, 4-SMD no-lead footprint

Operates from a single 3.3V supply rail and is housed in a 4-SMD no-lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm — a compact footprint suitable for space-constrained PCB layouts.
