NordicSemi pushes BLE boundaries with dual Cortex-M33




Nordic is pushing Cortex-M33 in its new “flagship” product, the nRF5340. With a dual core Cortex, it has all the latest bells and whistles of BlueTooth: all AoA and AoD roles in Bluetooth Direction Finding, Bluetooth Long Range and 2 Mbps. This makes yet another dull Covid-19 month a bit more spicy.

Microchip had another salvo of VAO (automotive grade) parts across the portfolio, from ATSAM to DSPIC33 and PIC16.
We are seeing a burst of activity on the AVR32 with the AVR32DA, a so-called “Functional Safety Ready” MCU with Peripheral Touch Controller (PTC). Don’t get fooled, it looks like it is a 8-bit MCU. Target markets include connected home security, building automation and sensor systems to automotive and industrial automation.
The core runs at 24 MHz and memory is up to 128 KB flash, 16 KB SRAM and 512 bytes of EEPROM, with 12-bit differential ADC, 10-bit DAC, analog comparators and zero cross detectors. The PTC enables capacitive touch interface designs supporting buttons, sliders, wheels, touchpads, smaller touch screens as well as gesture controls. The AVR32DA family supports up to 46 self-capacitance and 529 mutual capacitive touch channels with enhanced noise immunity, water tolerance, touch sensitivity and response time.
The AVR32DA family is available in volume production in 10,000 quantities starting at $0.87.
Nordic unveiled 2 new members of the nRF family, the nRF52805 and the nRF5340.
The nRF52805 covers the lower end of the product portfolio and only supports BLE, it is otherwise based on a similar feature set as the other nRF528xx siblings.
The nRF5340 sits at the opposite end of the spectrum and is labeled the “flagship”, packing 2 Cortex-M33 cores to support a superset of the most prominent nRF52 Series features including Bluetooth® Direction Finding, high-speed SPI, QSPI, USB, up to 105 °C operating temperature.

The application processor is optimized for performance and can be clocked at either 128 or 64 MHz, using voltage-frequency scaling. It has 1 MB Flash, 512 KB RAM, a floating-point unit (FPU), an 8 KB 2-way associative cache and DSP instruction capabilities. The network processor is clocked at 64 MHz and is optimized for low power and efficiency (101 CoreMark/mA). It has 256 KB Flash and 64 KB RAM.

The nRF5340 offers trusted execution, root-of-trust and secure key storage security features. Arm TrustZone provides trusted execution by implementing a division between secure and non-secure Flash, RAM, peripherals and GPIOs. The Arm CryptoCell-312 provides hardware-accelerated cryptography, and together with the key management unit (KMU) peripheral, root-of-trust and secure key storage are implemented.

The nRF5340 supports BLE, with all AoA and AoD roles in Bluetooth Direction Finding, in addition Bluetooth Long Range and 2 Mbps. Mesh protocols like Bluetooth mesh, Thread and Zigbee can be run concurrently with Bluetooth LE, enabling smartphones to provision, commission, configure and control mesh nodes. NFC, ANT, 802.15.4 and 2.4 GHz proprietary protocols are also supported.
