Why this MEMS oscillator fits an automotive clock tree
For a tier-one ECU program, the AEC-Q100 certificate is the gatekeeper — without it, the part doesn't enter the BOM. The 32.768 kHz output is the standard real-time clock reference for sleep timers, calendar counters, and CAN wake-up logic. CMOS output interfaces directly with MCU RTC inputs without external level translation.
Temperature range is -40°C to 85°C, matching the AEC-Q100 Grade 3 ambient band. For under-hood applications that see 105°C ambient, this part is not rated — step up to the DSC60XXB's 125°C variant if the ECU sits near the engine block. Frequency stability is ±25 ppm — tight enough for a USB or CAN clock reference but not for a precision GPS holdover oscillator.
Package and board layout note
4-VLGA package, 2.50 mm x 2.00 mm body, 0.89 mm seated height. The land pattern is a standard 4-pad VLGA footprint — no via-in-pad required. The small size frees board area on a dense ECU layout.
No official successor or second-source cross-reference is listed; the DSC60XXB series is the only family. No stock-holding claim; each order is sourced per the buyer's quantity and delivery window.
