Operational Principle 1. The 6210 is a member of the low-cost, high-performance family of intelligent 2.4 GHz RF transceivers with embedded microcontrollers. 2. The 6210 is optimized to provide a single chip solution for Ultra Low Power (ULP) wireless applications. The combination of processing power, memory, low power oscillators, real-time counter and a range of power saving modes provides an ideal platform for implementation of RF protocols. 3. Benefits of using 6210 include tighter protocol timing, security, lower power consumption and improved co-existence performance. For the application layer the 6210 offers a rich set of peripherals including: SPI (master and slave), UART, PWM, and so on. ANTENNA, The antenna is typically fed from the end of the monopole section by a plated through-hole via which is in turn connected to the RF output on the 2.4GHz band. Frequency Range: 2402-2480MHz
