Overview

---

The BK2480 series includes BK2481, BK2482 and BK2483.

The BK2480 is a single-chip 2.4 GHz RF system-on-chip (SoC) intended for low power wireless applications. The BK2480 combines advantages of the high-performance 2.4 GHz RF transceiver with an enhanced 8051 compliant MCU, 2 KB of RAM and 8 KB of OTP memory and essential peripherals.

Using advanced design techniques and ultra-low-power process technology, the BK2480 delivers high integration and minimal power consumption in small packages for target applications such as USB dongles, mouse devices, keyboards, remote controls, toys, and lighting.
