With solder mask defined pads, the overlap of the solder mask on the land creates a step in the solder at the land interface, which can cause stress concentration and act as a point for crack initiation. CSR recommends that the PCB land pattern is in accordance with IPC standard IPC-7351. Solder paste must be used during the assembly process. Typical Solder Reflow Profile For information, see Typical Solder Reflow Profile for Lead-free Devices Information Note. CSR1011 QFN Data Sheet Production Information © Cambridge Silicon Radio Limited 2012-2015 Page 15 of 48 CS-231986-DSP6 www.csr.com 2 2.1 Bluetooth Modem RF Ports CSR1011 QFN contains an integrated balun which provides a single-ended RF TX / RX port pin. No matching components are needed as the receive mode impedance is 50Ω and the transmitter has been optimised to deliver power in to a 50Ω load. 2.2 RF Receiver The receiver features a near-zero IF architecture that allows the channel filters to be integrated onto the die. Sufficient out-of-band blocking specification at the LNA input allows the receiver to be used in close proximity to GSM and W‑CDMA cellular phone transmitters without being significantly desensitised. An ADC digitises the IF received signal. 2.2.1 Low Noise Amplifier The LNA operates in differential mode and takes its input from the balanced port of the integrated balun. 2.2.2 RSSI Analogue to Digital Converter 2.3 RF Transmitter 2.3.1 IQ Modulator The transmitter features a direct IQ modulator to minimise frequency drift during a transmit packet, which results in a controlled modulation index. Digital baseband transmit circuitry provides the required spectral shaping. 2.3.2 Power Amplifier The internal PA has a maximum 9dBm output power without needing an external RF PA. 2.4 Bluetooth Radio Synthesiser The Bluetooth radio synthesiser is fully integrated onto the die with no requirement for an external VCO screening can, varactor tuning diodes, LC resonators or loop filter. The synthesiser is guaranteed to lock in sufficient time across the guaranteed temperature range to meet the Bluetooth v4.1 specification. 2.5 Baseband 2.5.1 Physical Layer Hardware Engine Dedicated logic performs: ■ Cyclic redundancy check ■ Encryption ■ Data whitening ■ Access code correlation The hardware supports all optional and mandatory features of Bluetooth v4.1 specification. Production Information © Cambridge Silicon Radio Limited 2012-2015 Page 16 of 48 CS-231986-DSP6 www.csr.com CSR1011 QFN Data Sheet The ADC samples the RSSI voltage on a packet-by-packet basis and implements a fast AGC. The front-end LNA gain is changed according to the measured RSSI value, keeping the first mixer input signal within a limited range. This improves the dynamic range of the receiver, improving performance in interference-limited environments. 3 Clock Generation The Bluetooth reference clock for the system is generated from an external 16MHz clock source, see Figure 3.1. All the CSR1011 QFN internal digital clocks are generated using a phase locked loop, which is locked to the frequency of either the external reference clock source or a sleep clock frequency of 32.768kHz, see Figure 3.1.

When CSR1011 QFN is connected to another digital device, UART_RX and UART_TX transfer data between the 2 devices. UART configuration parameters, e.g. baud rate and data format, are set using CSR1011 QFN firmware. When selected in firmware PIO[0] is assigned to a UART_TX output and PIO[1] is assigned to a UART_RX input, see Section 1.2. Note: To communicate with the UART at its maximum data rate using a standard PC, the PC requires an accelerated serial port adapter card. Parameter Baud rate Possible Values Minimum Maximum Parity 2400 baud (≤2%Error) 9600 baud (≤2%Error) 3.69Mbaud (≤0.1%Error) None, Odd or Even Number of stop bits 1 or 2 Bits per byte 8 Table 6.1: Possible UART Settings 6.1.1.1 UART Configuration While in Deep Sleep The maximum baud rate is 2400 baud during deep sleep. 6.2 I²C Interface The I²C interface communicates to EEPROM, external peripherals or sensors. An external EEPROM connection can hold the program code externally to the CSR1011 QFN. Figure 6.1 shows an example of an EEPROM connected to the I²C interface where I2C_SCL, I2C_SDA and PIO[2] are connected to the external EEPROM. The PIO[2] pin supplies the power to the EEPROM supply pin, e.g. VDD. At bootup, if there is no valid ROM image in the CSR1011 QFN ROM area the CSR1011 QFN tries to boot from the I²C interface, see Figure 6.5. This involves reading the code from the external EEPROM and loading it into the internal CSR1011 QFN RAM.

The protocol of this interface is proprietary. The 4 SPI debug lines directly support this function. The SPI programs, configures and debugs the CSR1011 QFN. It is required in production. Ensure the 4 SPI signals are brought out to either test points or a header. Take SPI_PIO#_SEL high to enable the SPI debug feature on PIO[8:5]. CSR1011 QFN uses a 16-bit data and 16-bit address programming and debug interface. Transactions occur when the internal processor is running or is stopped. Data is written or read one word at a time. Alternatively, the auto-increment feature is available for block access. 6.4.1 Instruction Cycle The CSR1011 QFN is the slave and receives commands on DEBUG_MOSI and outputs data on DEBUG_MISO. Table 6.5 shows the instruction cycle for a SPI transaction. Production Information © Cambridge Silicon Radio Limited 2012-2015 Page 29 of 48 CS-231986-DSP6 www.csr.com CSR1011 QFN Data Sheet Hardware Checks SPI Interface (Default Pins) 1 Reset the SPI interface Hold DEBUG_CS# high for 2 DEBUG_CLK cycles 2 Write the command word Take DEBUG_CS# low and clock in the 8-bit command 3 Write the address Clock in the 16-bit address word 4 Write or read data words Clock in or out 16-bit data word(s) 5 Termination Take DEBUG_CS# high Table 6.5: Instruction Cycle for a SPI Transaction With the exception of reset, DEBUG_CS# must be held low during the transaction. Data on DEBUG_MOSI is clocked into the CSR1011 QFN on the rising edge of the clock line DEBUG_CLK. When reading, CSR1011 QFN replies to the master on DEBUG_MISO with the data changing on the falling edge of the DEBUG_CLK. The master provides the clock on DEBUG_CLK. The transaction is terminated by taking DEBUG_CS# high. 6.4.2 Multi-slave Operation Do not connect the CSR1011 QFN in a multi-slave arrangement by simple parallel connection of slave MISO lines. When CSR1011 QFN is deselected (DEBUG_CS# = 1), the DEBUG_MISO line does not float. Instead, CSR1011 QFN outputs 0 if the processor is running or 1 if it is stopped. Production Information © Cambridge Silicon Radio Limited 2012-2015 Page 30 of 48 CS-231986-DSP6 www.csr.com CSR1011 QFN Data Sheet The auto increment operation on the CSR1011 QFN cuts down on the overhead of sending a command word and the address of a register for each read or write, especially when large amounts of data are to be transferred. The auto increment offers increased data transfer efficiency on the CSR1011 QFN. To invoke auto increment, DEBUG_CS# is kept low, which auto increments the address, while providing an extra 16 clock cycles for each extra word written or read. 7 Power Control and Regulation CSR1011 QFN contains 2 regulators: ■ 1 switch-mode regulator, which generates the main supply rail from the battery ■ 1 low-voltage linear regulator Figure 7.1 shows the configuration for the power control and regulation with the CSR1011 QFN. SMPS_LX VDD_REG_IN Switch VDD _CORE Low-voltage VDD_CORE Linear Regulator Digits 0.65 /1.20 V Figure 7.1: Voltage Regulator Configuration 7.1 Switch-mode Regulator The switch-mode regulator generates the main rail from the battery supply, VDD_BAT_SMPS. The main rail supplies the lower regulated voltage to a further digital linear regulator and also to the analogue sections of the CSR1011 QFN. The switch-mode regulator generates typically 1.35V. 7.2 Low-voltage VDD_CORE Linear Regulator The integrated low-voltage VDD_CORE linear regulator powers the CSR1011 QFN digital circuits. The input voltage range is 0.65V to 1.35V. It can supply programmable voltages of 0.65V to 1.20V to the digital area of the CSR1011 QFN. The maximum output current for this regulator is 30mA. Connect a minimum 470nF low ESR capacitor, e.g. MLC, to the VDD_CORE output pin. Software controls the output voltage. Important Note: This regulator is only for CSR internal use. Section 8 shows CSR's recommended circuit connection. 7.3 Reset CSR1011 QFN is reset by: ■ ■ 7.3.1 Power-on reset Software-configured watchdog timer Digital Pin States on Reset Table 7.1 shows the pin states of CSR1011 QFN on reset.
