I NTEGRATED R ADIO T RANSCEIVER The BCM2042 has an integrated radio transceiver that has been optimized for use in 2.4-GHz Bluetooth wireless systems. It has been designed to provide low-power, low-cost, robust communications for applications operating in the globally available 2.4-GHz unlicensed ISM band. It is fully compliant with Bluetooth Radio Specification v1.2 and meets or exceeds the requirements to provide the highest communication link quality of service. T RANSMITTER P ATH The BCM2042 features a fully integrated zero IF transmitter. The baseband transmit data is digitally GFSK modulated in the modem block and up-converted to the 2.4-GHz ISM band in the transmitter path, which contains signal filters, an I/Q up- converter, an output power amplifier (PA), and RF filters. Digital Modulator The digital modulator performs the data modulation and filtering required for the GFSK. The fully digital modulator minimizes any frequency drift or anomalies in the modulation characteristics of the transmitted signal and is much more stable than direct VCO modulation schemes. Digital Demodulator and Bit Synchronizer The digital demodulator and bit synchronizer take the low IF received signal and perform an optimal frequency tracking and bit synchronization algorithm. Power Amplifier The fully integrated PA provides a maximum output signal level of +4 dBm using a highly linearized, temperature compensated design. This gives the user greater flexibility in the type of front end matching and filtering to use with the BCM2042. Due to the linear nature of the PA combined with some integrated filtering, no external filters are required for meeting Bluetooth and regulatory harmonic and spurious requirements. R ECEIVER P ATH The receiver path uses a low IF scheme to down-convert the received signal for demodulation in the digital demodulator and bit synchronizer. The receiver path provides a high degree of linearity, an extended dynamic range, and high order on-chip channel filtering to ensure reliable operation in the noisy 2.4-GHz ISM band. The front end topology with built-in out-of-band attenuation enables the BCM2042 to be used in most applications with no off chip filtering. Digital Demodulator and Bit Synchronizer The digital demodulator and bit synchronizer take the low IF received signal and perform an optimal frequency tracking and bit synchronization algorithm. Receiver Signal Strength Indicator The radio portion of the BCM2042 provides an Receiver Signal Strength Indicator (RSSI) signal to the baseband so that the controller can take part in a Bluetooth power-controlled link by providing a metric of its own receiver signal strength to determine whether the transmitter should increase or decrease its output power. L OCAL O SCILLATOR G ENERATION Local Oscillator (LO) generation provides fast frequency hopping (1600 hops/sec) across the 79 maximum available channels. The LO generation subblock employs an architecture for high immunity to LO pulling during PA operation. The BCM2042 uses an internal RF and IF loop filter, which only requires one external capacitor. C ALIBRATION The BCM2042 radio transceiver features an automated calibration scheme that is fully self-contained in the radio. No user interaction is required during normal operation or during manufacturing to provide the optimal performance. Calibration, which accounts for process and temperature variations, optimizes the performance of all major circuit blocks within the radio. The gain and phase of all relevant filter blocks, amplifier blocks, and matching circuits are calibrated. Calibration occurs in the background during normal operation and during LO frequency hop setting times. I NTERNAL R EGULATOR To reduce the external BOM, the BCM2042 has an integrated 1.5V Low Dropout (LDO) regulator to provide power to the digital and RF circuits. This regulator operates from a 1.7V to 3.6V input supply with less than 50 mV of maximum dropout voltage at full load. A ferrite bead may be needed between the digital and RF supply pins to isolate noise coupling and suppress the noise into the RF circuits. For optimal performance, it is best to include a low-pass filter between the digital and RF supply pins; a pi filter circuit with two shunt caps and one 0603 ferrite bead will suffice. Figure 2 illustrates a sample LDO filter. Figure 2: LDO Filter M ICROPROCESSOR U NIT The Microprocessor Unit (μPU) runs software from the Link Control (LC) layer, up to the Host Controller Interface (HCI). The microprocessor is an enhanced performance 8051 microcontroller. The μPU also consists of one UART port, 2 KB of internal register RAM, 24 KB of internal SRAM, 112 KB of application ROM, and 16K of boot-ROM. An external EEROM up to 32 KB in size may be connected to customize the operation of the BCM2042 for a particular application. The EEPROM may also contain patch-code to modify application behavior, or to fix any bugs which may exist in the ROM code. The 8051 core is object code compatible with the industry standard 8051 microcontroller. E XTERNAL M EMORY I NTERFACE (120- PIN P ACKAGE O NLY ) The memory interface (available only on the 120-pin package) allows 8051 microcontroller accesses to two types of 8-bit wide external memory: Flash memory and SRAM. The interface can access 128 KB (1 Mbit) of external Flash memory, 128 KB of external SRAM with no bank switching required, or access 256 KB (2 Mbit) of Flash without access to SRAM. When using external Flash, 32 KB of the Flash may be used to contain configuration and patch-code, eliminating the need for an external EEPROM. When using a 256 KB (2 Mbit) or larger Flash, over-the-air firmware updates can be supported. B LUETOOTH B ASEBAND C ORE The Bluetooth Baseband Core (BBC) implements all of the time critical functions required for high performance Bluetooth operation. The BBC manages the buffering, segmentation, and routing of data for all connections. It also buffers data that passes through it, …
