General Description
The BC516x devices are high performance and low
cost GFSK transmitters for wireless applications in
the 2402MHz~2480MHz frequency bands. They
incorporate a highly integrated 2.4GHz transmitter,
a baseband modulator and an Encoder with
programmable data rates from 125Kbps to 500Kbps.
The frequency hopping function, which is informal
and transmits the same data to each selected channel,
can overcome the crowded frequencies.
External host MCU can access the BC5162 through
an I2C interface. However, the BC5161 has Key/WOT
modes, so it can be used for unidirectional wireless
applications such as Student ID CARD, motorcycle/
scooter keyless, etc. without MCU control.
