C-3L-M.
1 Summary Summary
C-3L-M integrates Bluetooth dual-mode 5.1 and Wi-Fi 802.11n with BK7231M chips. Integrate hardware
and software resources required to complete complete Wi-Fi and Bluetooth applications, can support AP
and STA dual-role connectivity, and both classic and low-power Bluetooth connectivity. The 32-bit MCU
with running speeds up to 120 MHz and the built-in 256 KB RAM, allow the chip to support
cloudy-cloud connectivity, and the MCU extended instructions for signal processing enable efficient
audio coding and decoding.
Has rich peripherals like PWM, I2C, UART, SPI, SDIO as well as IrDA. You can download and burn
programs directly through the UART. Up to six roads of 32-bit high speed PWM output using chips are
ideal for high quality LED control. Each 2 PWM can be configured as a phase controlled differential
mode to support motor and light band drive.
Priority-based Wi-Fi and Bluetooth coexistence control modules are integrated internally to achieve
real-time priority and transceiver scheduling.BK7231M can provide a transceiver state indication of the
current transceiver to support external PA and LNA extensions.
Inbedded eFUSE and supports OTP read and write within FLASH to provide unique serial numbers, code
encryption, and secure the debug interface. Internal integrates real random number generators and
security modules for secure and fast authentication and network connectivity.
Supporting low-power sleep mode, MCU can enter sleep and reach a micro-safe sleep current.The
BK7231M supports deep sleep modes, which can run 32-bit clocks at several microAnn currents, and can
be awakened by this clock or by any GPIO.
It supports not only classic Bluetooth standard rate connectivity, but also all BLE 5.1 rates and features,
including Long Range, High Data Rate, and AoA/AoD positioning of up to four antennas.
