Housed in a 4-SMD, no-lead package measuring 2.50 mm x 2.00 mm x 0.90 mm — small enough for space-constrained PCBs but still hand-solderable with a fine-tip iron and some patience. Surface-mount only; the no-lead footprint means the PCB land pattern should match the recommended layout in the datasheet to avoid tombstoning during reflow.
The standby function disables the oscillator output and reduces current consumption to 15 µA max. It is controlled by a dedicated pin — pulling it low (or high, depending on the logic) shuts the output off while keeping the internal bias alive for fast wake-up. This is useful for battery-powered devices that need to save power when the clock is not needed.
