The 2.25V to 3.6V supply range lets the oscillator run directly from a 2.5V or 3.3V rail without a separate LDO — a BOM simplification for mixed-voltage designs. The disable current is still significant — a power-gating FET on the supply rail may be needed if the system sleeps below 22 mA.
The 6-SMD no-lead package measures 5.00 mm x 3.20 mm with a seated height of 0.90 mm.
Yes, the DSC1121BM1-016.0000T carries AEC-Q100 ratings, meaning it has passed the automotive-grade stress tests for temperature cycling, ESD, and latch-up. This qualifies it for under-hood and chassis-domain applications.
It remains available for new designs and production.
The frequency stability is ±50 ppm over the full temperature range and lifetime. This is adequate for general-purpose MCU clocking but not for precision timing applications requiring ±25 ppm or better.
The evidence does not explicitly list RoHS compliance status. The part is from Microchip's DSC1121 series, which is typically RoHS-compliant, but this should be verified against the manufacturer's latest compliance documentation.
