HS6206 1Introduction

The HS6206 is a member of the low-cost, high-performance family of intelligent 2.4 GHz RF transceivers with embedded microcontrollers. The HS6206 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. Benefits of using HS6206 include tighter protocol timing, security, lower power consumption and improved co-existence performance. For the application layer the HS6206 offers a rich set of peripherals including: SPI (master and slave), UART, PWM, USB, and so on.

HS6206 3RF transceiver

The HS6206uses the same 2.4 GHz GFSK RF transceiver with embedded protocol engine. The RF transceiver is designed for operation in the world wide ISM frequency band at 2.400–2.4835 GHz and is very well suited for ultra-low power wireless applications.

The RF transceiver module is configured and operated through the RF transceiver map. This register map is accessed by the MCU through a dedicated on-chip Serial Peripheral interface (SPI) and is available in all power modes of the RF transceiver module. The embedded protocol engine enables data packet communication and supports various modes from manual operation to advanced autonomous protocol operation. Data FIFOs in the RF transceiver module ensure a smooth data flow between the RF transceiver module and the HS6206MCU.

The rest of this chapter is written in the context of the RF transceiver module as the core and the rest of the HS6206 as external circuitry to this module.

3.3Functional description

This section describes the different operating modes of the RF transceiver and the parameters used to control it.

The RF transceiver module has a built-in state machine that controls the transitions between the different operating modes. The state machine is controlled by SFR register RFCON and RF transceiver register CONFIG.

3.4Operational Modes

The HS6206 has a built-in state machine that controls the transitions between the chip’s operating modes. The state machine takes input from user defined register values and internal signals.

The state diagrams in Figure 3.2 shows the operating modes and how they function. There are three types of distinct states highlighted in the state diagram:

●Recommended operating mode: is a recommended state used during normal operation.

●Possible operating mode: is a possible operating state, but is not used during normal operation.

●Transition state: is a time limited state used during start up of the oscillator and settling of the PLL.
