7. Functional schematic
7.1 CPU
BC30 built-in ARM Cortex M4 32-bit microprocessor (MCU) with ultra low
16-bit RSIC for power consumption. The CPU clock speed is 80 MHz and can be up to 160 MHz.
Support for real-time operating system (RTOS). Currently, the Wi-Fi protocol stack uses only 20%
of MIPS, and others can be used for application programming and development. The CPU includes
the following interfaces:
◆ Configurable RAM/ROM (iBus) with on-chip memory controller and external Flash
◆ Data RAM interface (dBus) connected to the storage controller
◆ Access register AHB interface
7.2 Built-in storage
The BC30 chip has a built-in memory controller that includes ROM and SRAM. The MCU
can access the memory controller through the iBus, dBus, and AHB interfaces. All storage units
can be accessed after the request is initiated. The storage arbiter determines the order of access

based on when the processor accepts these requests. According to the SDK provided by our
company, when the BC30 is running in the Station mode and connected to the route, the available
SRAM space in the Heap+ Data area is 96kB. Embedded 8Mbit Flash storage.
7.3 External Flash
The BC30 uses an external SPI Flash to store the user program. In theory, it can support up to
16MB of storage.
8. Applications

also display a label referring to the enclosed module. This exterior label can use
wording such as the following:
“Contains Transmitter Module FCC ID: 2AQSK-BC30”
When the module is installed inside another device, the user manual of this device
must contain below warning statements; 1. This device complies with Part 15 of the
FCC Rules. Operation is subject to the following two conditions: (1) This device may
