BLUECORE4-PC-ROM WLCSP DRIVER

CSR reserves the right to make technical changes to its products as part of its development programme. Output is high impedance when chip is in Deep Sleep mode. Power ramping is internal. All hardware and device firmware is fully compliant with the Bluetooth v2. Nevertheless, because each symbol now represents 3 baseband bits, the actual throughput of the data is 3x when compared with the basic rate packet.

The external reference clock signal should meet the specifications outlined in Table 5. Frequency trim is achieved by adjusting the crystal load capacitance with an on-chip trim capacitor, Ctrim.

The driver amplifier may be considered as a circuit that provides negative resistance. To improve the performance of both Bluetooth and The value of transconductance is variable and may be set for optimum performance. The MCU, interrupt controller and event timer run the Bluetooth software stack and control the Bluecore4-pc-ron radio and host interfaces.

This architecture minimises the intervention required by the processor during transmission and reception. All electrical specifications may be changed by CSR without notice.

The BlueCore™ Technology Roadmap

Bluetooth EDR could offer a potential cost-effective solution for removing the wires from such systems. Intel wireless co-existence, internally reserved. Intel wireless co-existence, WLAN. Any of the PIO lines can be configured as interrupt request lines or as wake-up lines from sleep modes. Page, Inquiry, Page-Scan and Inquiry-Scan All standard pairing, authentication, link key and encryption operations Standard Bluetooth power saving mechanisms: Radio elcsp may occur after 6ms after the firmware starts.

This feature is typically used to remove initial tolerance frequency errors associated with the crystal. Zero is the default entry for 5ms delay.

BlueCore4 IC family

Limiting USB polling to only those times that actual data is ready on the Bluetooth module would reduce the impact Bluetooth has on overall system power consumption. The maximum value of this resistor oscillation occurs is the equivalent negative resistance of the oscillator. Bluetooth has previously been restricted to application in ink-jet printers but EDR will enable data to be transmitted at speeds suitable for laser printers. Power ramping is external.

Its value is calculated as follows: SPI Write Operation 8. The DAC output is derived from the on-chip band gap and is virtually independent of temperature and supply voltage.

All hardware and device firmware is fully compliant with the Bluecorre4-pc-rom v2. The device incorporates auto-calibration and built-in self-test BIST routines to simplify development, type approval and production test. The crystal appears inductive near its resonant frequency.

Refer to the software build release note for a detailed description. Auxiliary functions available on the analogue interface include a bit ADC.

For example, the arrows shown in Figure 4. Supports all Bluetooth v1.

The check word may be used to confirm a read operation to a memory location. It has two planes, each having four points. Production Data Sheets supersede all previous document versions. This ensures that the TCXO is oscillating at start up.
