Hi Chetan
The DW1000 is our first, mature UWB chip. We also have the DWM1000(C), DWM1001 and DWM1004 modules and the DWS1000 Arduino compatible shield based on it.
The DW3000 is a new UWB chip range that is still being released, which is why there is limited availability and documentation. We also plan to release DWM3xxx and DWS3xxx shields based on it. Mass production is planned for late June - early July.
The main differences between the DW3000 and DW1000:
- The DW3000 is designed for lower power operation
- The DW3000 supports higher SPI speeds
- The DW3000 should result in a lower total BOM cost and count (e.g requiring less caps)
- The DW3000 supports UWB channel 9 operation (important for TELEC/Japan market)
- The DW3000 has embedded AES-256 encryption support for secure timestamping, 4z BPRF compliant
- The DW3000 has a slightly lower TX power than the DW1000
- We plan to release versions of the DW3000 that support PDoA in a single chip
- The DW3000 will be available in more compact (CSP, QFN) packages.

Note that the DW1000 and DW3000 are not register compatible.
