Description

General description

BX2400 is a system chip that integrates an application processor, memory, encryption engine, power management unit, digital and analog peripherals, as well as a MAC engine and wireless transceiver compliant with Bluetooth 5.0. A 32-bit micro controller is integrated in the BX2400 for BLE link layer management and system operation.

Rich digital and analog peripheral interfaces are optimized for external control, including GPIO, SPI, UART, IIC, PWM, ADC and LDOs. The POWER management unit and on-chip DCDC step-down converters and various regulators make the BX2400 ultra-low power consumption a reality.

 

Feature

  • Compatible with BLE 5.0, support 1Mbps/2Mbps data switching
  • Support SIG Mesh
  • Meet BQB/SRRC/FCC/CE testing standards
  • CPU Benchmarking:2.07 Coremark/Mhz

 

Transceiver radio

  • Working frequency:2.4~2.5GHz
  • 1Mbps mode receiving sensitivity rate:-93dBm
  • 2Mbps mode receiving sensitivity rate:-90dBm
  • RF output power level: -20dBm to +8dBm
  • 50dB RSSI dynamic range
  • The ideal DCDC converter has a receiving current of 3.4mA and transmitting current of 3.5mA at 4.3V
  • When the DC DC converter is 4.3V, the receiving current is 4.3mA and the transmitting current is 4.4mA
  • When the DC DC converter is 3.3V, the receiving current is 5.5mA and the transmitting current is 5.6mA

 

Clock and Octave

  • 32MHz crystal and RC oscillator
  • 32KHz crystal and RC oscillator
  • Supports 96/80/64/48/32/16mhz octave

 

Analog interface

  • 10-bit ADC (oversampling to 12-bit)
  • Temperature sensor range: -40℃~85℃

 

Digital interface

  • Up to 27 GPIOs
  • 5 PWM outputs
  • IO state is maintained during deep sleep
  • Four – line SPI Flash interface
  • 2 SPI host: speed up to 24Mbps and each channel has 2 chip options
  • 1 SPI slave: speed up to 8Mbps
  • 2 UART: flow control up to 1Mbps, support all baud rates below 1Mbps, support infrared
  • 2 I2C: can be master and slave, the maximum speed is 1Mbps
  • 2 way timer and 1 way watchdog

 

Built-in MCU
