BC5161/BC5162
2.4GHz GFSK Transmitter with Encoder
(BC5161/62 Restricted Products. Notification Date : 2024/10/11 Effective Date : 2025/01/11)
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.
