Product details

MEMS oscillator for 26 MHz clock trees

Running from a single 1.8V supply, it draws 7.5 mA max during operation and drops to 1 µA typ in standby (power-down) mode — the disable current is low enough that the oscillator can be gated directly by a GPIO without a separate load switch.

For a battery-powered sensor node that sleeps 99% of the time, the oscillator's contribution to the sleep current is negligible — the MCU's own leakage will dominate.

Housed in a 4-VDFN exposed pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm, the DSC1505AI3A-26M00000 is a surface-mount device.

Frequently asked questions

Is the DSC1505AI3A-26M00000 RoHS compliant?

The evidence does not list a RoHS compliance statement. Microchip's standard MEMS oscillator portfolio is typically RoHS-compliant, but confirm the specific date-code lot against the manufacturer's RoHS certificate at order time.

What is the frequency stability of the DSC1505AI3A-26M00000?

This is tight enough for most MCU clock trees and USB full-speed applications without requiring a separate TCXO.
