Product details

It is not recommended for new designs, and no direct pin-compatible successor is cited in the official record. Available through independent surplus distribution in lot-specific quantities; availability confirmed at RFQ.

27 MHz MEMS oscillator with standby mode

This is a MEMS-based XO (Standard) in the DSC1033 PureSilicon™ series, delivering a 27 MHz CMOS output from a 3.3V supply. The standby (power-down) function pulls the disable current to 1µA max, making it suitable for battery-operated or duty-cycled systems where the oscillator must shut down between active periods.

The 4-SMD no-lead package measures 2.50mm x 2.00mm with a seated height of 0.90mm — a compact footprint for space-constrained PCBs.

Frequency stability and supply current

Frequency stability is ±50ppm, which holds the clock edge within tight tolerance for UART baud-rate generation or MCU timing without external trimming. Typical supply current is 3mA max at 27 MHz, keeping the thermal contribution low in dense layouts.

Frequently asked questions

What is the replacement for DSC1033DI1-027.0000T?

No official successor is listed by Microchip Technology for this specific order code. For a new design, consider a current-production MEMS oscillator in the same 4-SMD no-lead footprint with 27 MHz CMOS output and standby function — confirm pin compatibility and electrical ratings with the datasheet before committing.

Does the DSC1033DI1-027.0000T have a standby mode?

Yes, the function is Standby (Power Down). When disabled, the supply current drops to 1µA max, allowing the oscillator to be shut down between active periods to conserve power.

Can the DSC1033DI1-027.0000T be used in automotive applications?

For automotive-grade timing, select a part with explicit AEC-Q100 or AEC-Q200 certification.
