FDC1004: Looking for Part

Part Number: FDC1004
Other Parts Discussed in Thread: FDC2214

Hello, I am looking for a dedicated cap sensing device that has sensitivity to the single digits femto-range. My project will powered by a 3V coin cell so I really need the device to be low power. The higher accuracy the better.

Is there a device that is this sensitive and operates at low voltages ?
