Product details

The DSC6041JA3B-001.0240T: In a battery-backed always-on domain (CAN transceiver wake-up, RTC calibration, security monitor), the 1.3 mA draw is a small fraction of the sleep budget.

Frequency stability and timing margin

Frequency stability is specified at ±20 ppm total — this includes initial tolerance, temperature drift, and aging combined. For a 1.024 MHz clock, ±20 ppm translates to roughly ±20 Hz of absolute error. That is tight enough for CAN bus (which tolerates ±0.5% bit-rate error) and for general-purpose microcontroller clocking, but not tight enough for precision timekeeping or Ethernet PHY reference clocks.

The 4-pin land-grid array footprint is standard for MEMS oscillators in this form factor — no special via pattern or thermal pad required.

Frequently asked questions

What is the output type and logic family of DSC6041JA3B-001.0240T?

The output is CMOS — a single-ended, rail-to-rail digital signal that drives standard CMOS logic inputs directly without external termination or level translation.

What compliance documentation does Microchip provide for DSC6041JA3B-001.0240T?

The part carries AEC-Q100 automotive qualification, which covers the full reliability stress test suite (temperature cycling, ESD, latch-up, high-temperature operating life). RoHS and REACH compliance documentation is standard for Microchip's DSC60XXB series.
