2.2. Powerful CPU
The main chip of the MWG01 Gateway is the STM32H743 Microcontroller of Italy Semiconductor Co., Ltd.,
which is based on the Arm®Cortex®- M7 kernel (with dual precision floating point unit) and operates
at a frequency of up to 480 MHz.. When executing a program from the Flash, the STM32H743/753 series
can provide performance of 2400 CoreMark /1027DMIPS, thanks to its L1 cache and implementation of zero
waiting execution. the digital signal processor (DSP) instruction and the dual-precision floating-point
unit (FPU) expand the application of the product. (d) benefits the L1 cache (16 KB I- cache 16 KB D-
cache), even using external memory does not cause performance losses.also, it provides BGA and LQFP
package models for 100 to 240 pins.STM32H743 has rich and flexible power management mechanism. The
multi-source architecture can optimize the power efficiency by configuring different power domains into
low-power modes. the device is embedded with a voltage regulator powered by the USB physical interface
layer (PHY) and a backup voltage regulator in addition to the main voltage regulator that supplies power
to the USB physical interface layer (PHY) and a backup voltage regulator. Typical power consumption
values are 275µA/MHz @VDD =3.3 V and 25µA/MHz @VDD =C in kernel mode (off peripherals),typical power
consumption current in low power standby mode is 2.95µA.
OTG controller, ethernet MAC,SPDIF-IN,HDMI-CEC, camera interface, single line protocol interface,
and MDIO slave devices.So you can have multiple upward communication channels on the MWG01, including
but not limited to: Ethernet、Wifi、4G/5G、NB-IoT、LoRa, etc. And has four simultaneously working Bluetooth
modules.
2.3.Co-processor with MESH Bluetooth Protocol Stack
Four coprocessors with Bluetooth protocol stacks are divided into two groups:
