General Description
Applications
CSR1010D QFN is a CSR µEnergy platform device.
CSR µEnergy are CSR's single-mode Bluetooth low
energy products for the Bluetooth Smart market.
CSR1010D QFN increases application code and data
space for greater application development flexibility.
CSR μEnergy enables ultra low-power connectivity and
basic data transfer for applications previously limited by
the power consumption, size constraints and complexity
of other wireless standards. CSR1010D QFN provides
everything required to create a Bluetooth low energy
product with RF, baseband, MCU, qualified Bluetooth
v4.1 specification stack and customer application
running on a single IC.
CSR is the industry leader for Bluetooth low energy, also
known as Bluetooth Smart. Bluetooth Smart enables
connectivity and data transfer to leading smartphone,
tablet and personal computing devices including Apple
iPhone, iPad, iPod and Mac products and leading
Android devices.
Building a smart lighting ecosystem using
Bluetooth low energy and CSRmesh™
Bluetooth low energy takes less time to make a
connection than conventional Bluetooth wireless
technology and can consume approximately 1/20th of
the power of Bluetooth Basic Rate.
CSRmesh places the smartphone at the centre of the
Internet of Things allowing an almost unlimited number
of Bluetooth Smart enabled devices to be simply
networked together and controlled directly from a single
smartphone, tablet or PC.

PCB Design and Assembly Considerations
This section lists recommendations to achieve maximum board-level reliability of the 5 x 5 x 0.6mm QFN 32-lead
package:
■
■
■
1.5
NSMD lands (lands smaller than the solder mask aperture) are preferred, because of the greater accuracy of
the metal definition process compared to the solder mask process. 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

2.1
Bluetooth Modem
RF Ports
CSR1010D 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.

CSR1010D 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 CSR1010D 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.

The frequency of the slow clock is periodically calibrated against the system clock. As a result the rate of change of the frequency is more
important than the maximum deviation. To meet the accuracy requirements the frequency should not drift due to temperature or other effects
by more than 80ppm in any 5 minute period.
(b)
CSR1010D QFN can correct for ±1% by using the fast clock to calibrate the slow clock.

Serial Interfaces
6.1
Application Interface
6.1.1
UART Interface
The CSR1010D QFN UART interface provides a simple mechanism for communicating with other serial devices using
the RS232 protocol.
2 signals implement the UART function, UART_TX and UART_RX. When CSR1010D 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 CSR1010D 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.

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 CSR1010D 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 CSR1010D QFN ROM area the CSR1010D 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
CSR1010D QFN RAM.

Programming and Debug Interface
Important Note:
The CSR1010D QFN debug SPI interface is available in SPI slave mode to enable an external MCU to program
and control the CSR1010D QFN, generally via libraries or tools supplied by CSR. The protocol of this interface is
proprietary. The 4 SPI debug lines directly support this function.
The SPI programs, configures and debugs the CSR1010D 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].
CSR1010D 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 CSR1010D 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.

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 CSR1010D QFN on the rising edge of the clock line DEBUG_CLK. When reading, CSR1010D 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 CSR1010D QFN in a multi-slave arrangement by simple parallel connection of slave MISO lines.
When CSR1010D QFN is deselected (DEBUG_CS# = 1), the DEBUG_MISO line does not float. Instead,
CSR1010D QFN outputs 0 if the processor is running or 1 if it is stopped.

CSR1010D QFN Data Sheet
The auto increment operation on the CSR1010D 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 CSR1010D 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.

Power Control and Regulation
CSR1010D 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 CSR1010D QFN.

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 CSR1010D 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 CSR1010D 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
CSR1010D 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.
