 BK2411
BK2411/BK2412
v0.5
1 General Description
BK2411/BK2412 is a FSK/GFSK transceivers operating in the world wide ISM
frequency band at 2.397 – 2.4835 GHz. The embedded packet processing engine enables
its full operation with a very simple MCU as a radio system. Burst mode transmission
and up to 2 Mbps air data rate make it suitable for applications requiring ultra low power
consumption. Auto re-transmission and auto acknowledge give reliable link without any
MCU interference.
2 Key Features
z Worldwide 2.4 GHz ISM band operation
z FSK enables better sensitivity and GFSK gives better spectrum efficiency
z 1 Mbps or 2 Mbps air data rate
z Programmable output power: -35, -25, -15, -5, 0, 5 dBm
z TX 14 mA power consumption at 0 dBm output power
z RX 21mA power consumption at 1 Mbps air data rate
z Tolerate +/- 60ppm 16 MHz crystal
z Three levels variable payload length from 1 to 32 bytes, or one level variable payload
length from 1 to 255 bytes
z Automatic packet processing
z 6 data pipes for 1:6 star networks
z 1.9 V to 3.6 V power supply
z 3 uA DC current at power down mode and 410 uA in standby-I mode
z 4-pin SPI interface with MCU with maximum 8 Mbps clock rate
z Compact 20-pin 4x4 mm QFN package for BK2411
z Compact 24-pin 4x4 mm QFN package for BK2412 with separate TX and RX
antenna interface
3 Applications
z Wireless mouse, keyboard and joystick
