| Case | 6-VDFN Exposed Pad |
The 2.25V to 3.6V supply range covers both 2.5V and 3.3V logic rails without an extra regulator.
The 6-VDFN exposed-pad package measures 7.00 mm x 5.00 mm with a seated height of 0.90 mm. Use a 0.50 mm pitch stencil for the perimeter pads; the centre pad needs a via array under the part to pull heat into the inner layers.
The DSC1101AL3-PROGT ships blank and requires programming before use. Microchip provides a programming tool and software (typically a TimeFlash or similar programmer) that writes the target frequency into the device's internal non-volatile memory. The part can be programmed on a strip or after soldering if the board provides access to the programming pins. Refer to the DSC1101 series programming guide for the exact pin sequence and timing.
The standby (power-down) function disables the output and puts the oscillator into a low-power state. When the standby pin is asserted, the output goes high-impedance and the supply current drops to a few microamps — typically below 1 µA. This is useful for battery-powered systems that need to disable the clock tree during sleep modes.
