The DSC1001BI2-036.0000T is a 36 MHz MEMS-based oscillator with CMOS output, built for environments where a quartz crystal's vibration sensitivity or startup time is a liability. Rated across -40 to 85°C with ±25 ppm frequency stability, it holds the clock edge through temperature swings that would pull a ceramic resonator off-frequency. The AEC-Q100 qualification places this part in the automotive-grade bucket — suitable for engine bay, chassis, or infotainment domains where the thermal cycle count and shock profile exceed commercial-grade limits.
Power budget and standby current
Supply current max is 7.2 mA during active oscillation; the standby (power-down) pin drops draw to 15 µA — low enough to leave the oscillator powered from a battery-backed rail without draining the coin cell during sleep intervals. The supply voltage range spans 1.8 V to 3.3 V — a single part number covers 1.8 V, 2.5 V, and 3.3 V logic rails without a separate VDD variant, simplifying BOM line-item consolidation across multiple boards in the same product family.
Package fit and board layout
Housed in a 5.00 mm x 3.20 mm, 4-SMD no-lead package with a seated height of 0.90 mm. The 4-pin footprint is the same as many quartz XO packages — no layout change needed if replacing a standard crystal oscillator on an existing PCB, provided the supply voltage and enable logic match.
The DSC1001 series is an ongoing production line from Microchip Technology.
