MediaTek MT7622 SoC with WiFi Network Accelerator Supports 4×4 802.11n WiFi & Bluetooth 5

MediaTek has launched a new ARM SoC for routers, home automation gateways, wireless audio and storage, with MT7622 equipped with a dual core ARM Cortex A53 processor, a dedicated network accelerator, 4×4 802.11n and Bluetooth 5 connectivity. Two models with be available: MT7622A with all features, and MT7622B with router features only, which probably mean no Bluetooth, and possibly less I/Os.

MediaTek MT7622 specifications:

  • Processor – Dual core ARM Cortex A53 @ up to 1.36 GHz
  • Storage – eMMC and SDXC interfaces; storage accelerator (SATA 3.0/eSATA Gen2)
  • Connectivity
    • 802.11b/g/n WiFi @ 2.4GHz, 4T4R antenna; 802.11ac can be added through MT7615 SoC
    • Bluetooth 5
    • Fast Ethernet Switch, RGMII and SGMII
  • Network Accelerator – APT+HQoS,  MediaTek Wi-Fi Warp Accelerator
  • Audio – Audio Amplifier, I2S, TDM, S/PDIF
  • USB – USB 2.0 host/device, USB 3.0 host
  • Other Peripheral Interfaces – PCIe Gen 2.0, ADC, GPIO, I2C, IR, PMIC I/F, PWM, SPI, UART
  • Misc – RTC

The specs on the product page are currently all over the place, with “Zigbee” also dropped somewhere in the text, but not in the specifications list, nor is Bluetooth 5. They also wrote Bluetooth 5.0 instead of Bluetooth 5, but it’s a minor issue. They however provide some more details about the WiFi Warp accelerator:

Firstly it connects the Gigabit+ class 802.11ac networking through to the Gigabit switch/WAN connection via multi-Gigabit internal pathways, ensuring no bottleneck. Secondly, its specialized design not only offloads the CPU from many-user throughput and QoS calculations, it does so at lower power. The result is the MediaTek Wi-Fi Warp Accelerator maintains a sustained high-performance when even supporting multiple, simultaneous heavy users.

Another good news is that MediaTek engineers have started to contribute MT7622 related code to mainline Linux.

    Does this “PCI-Express:
    Host(2) Gen 2.0” mean PCIe 2.0 2 Lanes?

    Why make new SoC sfor networking today with no native IEEE 802.11ac support?

    Specs for connectivity says “802.11b/g/n WiFi” but product page mention “802.11ac networking”.

    Either it has native support for 802.11ac or it does not, or? Someone needs sleep.

    @Philipp Blum
    Yeah.. Some parts of the specs are hard to decode, so it’s anybody’s guess at this stage.

    @Harley
    802.11ac can be added via an external SoC. They may have a good reason for doing so. Maybe some markets mostly use 802.11n since higher speed broadband may not be available/popular.

    Sounds like shades of the stuff Qualcomm did with the IPQ series. There’s an extensive offload processor…that only works for select classes of IP flows. Coupled with some crippling design decisions Qualcomm did that impair memory performance and I/O performance for the normal use cases, the devices have been lackluster unless you’ve got one of the contexts that offloads well- which then the IPQ’s shine.

    I’m confused about the storage accelerator part too, or do they mean SATA/eSATA is the accelerator here?

  1. No trackbacks yet.
