The new nRF54H20 chip, which is part of the upcoming nRF54 series, will be manufactured on GlobalFoundries' 22FDX and "capable of supporting Bluetooth 5.4 and future Bluetooth specifications, as well as LE Audio, Bluetooth mesh, Thread, Matter and more," Nordik said. "Its combination of functions will allow to create complex end products that were previously impossible.”
The company remains tight-lipped about the number of processors, but said: “Each processor is optimized for a specific type of workload. The dedicated application processor has double the power of the application processor in the nRF5340 SoC.”
As a guide: Nordic credits the previous dual Cortex-M33 nRF5340 with 514 CoreMark and 66 CoreMark/mA. at 128 MHz and 257 CoreMark and 73 CoreMark/mA at 64 MHz.
The new part, the nRF54H20, will get 2MB of non-volatile memory and 1MB of RAM, and Nordic also claims it will be "ideal for complex machine learning and supporting sensor connectivity at the edge."
It will receive an external memory interface of 400 MB/s, USB 480 Mbit/s, dual I3C, a CAN FD controller and a 14-bit ADC.
The 2.4GHz multiprotocol radio is brand new, the company says, with -100dBm Rx sensitivity (1Mbps Bluetooth LE) and up to 10dBm transmit power. “Rx current consumption is half that of the nRF5340,” it claims.
Again for reference, the literature for the nRF5340 (referenced below) states that the Rx consumption is 2.7mA at 1Mbps and 3.1mA at 2Mbps (from 3V via DC-DC).
On-chip security is designed for PSA Certified Level 3 and supports secure: downloads, firmware updates and storage. According to Nordic, its cryptographic accelerators are protected against attacks from third-party channels, and intrusion sensors detect and respond to an ongoing attack.
The device performs sampling for the selected clients.
