MediaTek Unveils MT7686, MT7682, and MT5932 WiFi SoCs for IoT and Smart Home Applications

Beside announcing MT7622 SoC for WiFi and Bluetooth 5 gateways and routers last week, Mediatek also introduced three “next generation” WiFi SoCs for the IoT and the Smart Home market during Computex 2017, namely MT7686, MT7682, and MT5932.

Mediatek MT7686 is a wide temperature range WiFi SoC for appliances:

MCU – ARM Cortex-M4F @ 192 MHz
System Memory – 4MB + 384KB RAM
Storage – 4 MB flash with XIP support
Connectivity – Low-power 1T1R 802.11 b/g/n Wi-Fi subsystem
Peripherals – SDIO I/F, UART, I2C, SPI, I2S, PWM, and auxiliary ADC
Power Supply – Integrated Power Management Unit (PMU)
Power Consumption – Connected DTIM1 <0.7mA
Temperature Range – “Wide”
Package – QFN48 (6x6mm)

Mediatek MT7682 is promoted as a cost-effective, integrated SoC for multi-Cloud platforms:

MCU – ARM Cortex-M4F @ 192 MHz
System Memory – 384KB RAM
Storage – 512 KB or 1 MB flash with XIP support
Connectivity – Low-power 1T1R 802.11 b/g/n Wi-Fi subsystem
Peripherals – SDIO I/F, UART, I2C, SPI, I2S, PWM, and auxiliary ADC
Power Supply – Integrated Power Management Unit (PMU)
Power Consumption – Connected DTIM1 <0.7mA
Package – QFN40 (5x5mm)

Finally Mediatek MT5932 is a “companion chipset” with WiFi Direct support:

MCU – ARM Cortex-M4F @ 192 MHz
System Memory – 384KB RAM
Connectivity – Low-power 1T1R 802.11 b/g/n Wi-Fi subsystem with Wi-Fi Direct, support for 100% offload SDIO/SPI WiFi
Peripherals – SDIO I/F, UART, I2C, SPI, I2S, PWM, and auxiliary ADC
Power Supply – Integrated Power Management Unit (PMU)
Power Consumption – Connected DTIM1 <0.7mA
Package – WLCSP (3.2×3.2mm)

MediaTek also mentions that MT5932 “connected Smart Home and Office family supports the MediaTek LinkIt Development Platform for RTOS“, so we may expect a hardware development kit (HDK) in a few weeks or months.

Two advantages of the three new SoCs is that they “have been optimized to deliver a 300 percent improvement in energy efficiency, as well as the ability for a device to re-establish a Wi-Fi connection within 0.1 seconds of waking from sleep mode,” according to YuChuan Yang, Deputy General Manager of Internet of Things Business Unit, MediaTek.
