26 MHz MEMS oscillator with automotive-grade reliability
AEC-Q100 qualification means this part has passed automotive-grade stress tests including temperature cycling, ESD, and latch-up — it is specified for under-hood and chassis-domain electronics where a standard crystal oscillator would not survive the vibration and thermal shock. The MEMS resonator eliminates the quartz crystal's mechanical failure modes — no start-up reliability concerns from cracked blanks or degraded activity dips over the product lifetime.
Standby power-down for battery-conscious designs
A dedicated Standby (Power Down) function drops the supply current to 15 µA max — this is the draw when the oscillator is disabled but the supply rail remains live, critical for automotive ECUs that must wake from a CAN message without draining the battery during parking. Active supply current is 6.3 mA max at 26 MHz — the MEMS architecture keeps the power budget low enough for a shared 1.8V or 3.3V rail without a dedicated LDO.
Package and rework considerations for the 4-SMD no-lead
Housed in a 4-SMD, No Lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm — this is a standard MEMS oscillator footprint, compatible with the common 2.5 x 2.0 mm land pattern used by SiTime and other MEMS suppliers. The no-lead package has a small thermal mass — a hot-air rework station at 300°C with a 3 mm nozzle lifts the part cleanly in about 8 seconds without heating the adjacent passives.
Microchip lists the DSC1001DI2-026.0000T as Active — no end-of-life notice on file, no last-time-buy window. It is suitable for both new designs and production replenishment.
