It draws a maximum of 4 mA from the 1.8 V rail, and the standby (power-down) feature drops supply current to 1 µA — useful for battery-powered or intermittently operated equipment where the clock must be gated off between active periods.
Microchip has classified the DSC1018DI1-048.0000T as Obsolete. No official successor or direct pin-compatible replacement is recorded from Microchip.
No official replacement or pin-compatible successor is recorded from Microchip. A functional replacement would require evaluating a different part number with matching frequency, supply voltage, package, and output type — a board spin may be necessary.
Yes, the standby (power-down) function is listed. When enabled, the supply current drops to 1 µA maximum, allowing the oscillator to be gated off while preserving the rest of the circuit.
