The RN4870 Bluetooth Low Energy module is designed for easy implementation into a broad range of applications. It delivers up to 2.5x throughput improvement and more secure connections vs. Bluetooth 4.1 based products. Developers can easily interface to the device via a standard UART interface, available on most Microcontrollers and Processors. The RN4870 has a completely integrated Bluetooth software stack, and offers a shielded regulatory certified version with built-in antenna. Developers are freed from the complexities of Bluetooth Software and RF development and can simply utilize the RN4870 as a wireline replacement. Perfect for IoT (Internet of Things) applications, when interfaced to a Bluetooth Low Energy enabled smartphone or Bluetooth Internet Gateway, applications can be monitored, controlled and updated from anywhere in the world.

As part of the FIPS 140-3 certification process, the **SP800-90B** entropy validation will now be done using the Entropy Source Validation Test Server (ESVTS). These tools remain as part of the overall Cryptographic Module Validation Program (CMVP). A provider of the Entropy Source will still need to work with a NIST accredited cryptographic security laboratory to achieve certification. Once an entropy source has been validated it will now be allowed to be used by end systems without each end system having to recertify the entropy source. This will help to reduce the certification time of a system and improve the overall time to market. Our new cost-efficient, ready-to-use, standalone random number generator IC device meets the design principles and requirements for entropy sources used by random-bit generators with CMVP "ESV" certification of the entropy source and "ACVTS" certification of the Hash\_DRBG function. A validated entropy source is not module specific and end users can more efficiently complete their FIPS module evaluation by referring to the pre-certification elements of the RNG90 device. The FIPS certification process take about about 2 years wherein 8-11 months are consumed by the 3rd party laboratory for action items such as documentation review, data review, report creation, report submission, wait time in queue for approval, answer question from FIPS. The usage of the RNG90 will reduce the process by 1-2 months accelerating the evaluation phase.
