AR Datasheet, PDF – Alldatasheet

The RTC block also manages resets going to other modules with the device. This clock is completely independent from those mentioned above and is driven by the external host to communicate with the AR This clock drives the interface logic as well as a few registers which can be accessed by the host. A ro e nf Co s en id ial t The high speed clock is operational and sent to each block enabled by the clock control register Lower level clock gating is implemented at the block level, including the CPU, which can be gated off using the WAITI instruction while the system is on.

The I and Q signals are low-pass filtered and amplified by the baseband programmable gain filter controlled by digital logic. See the Host Interface chapter for a table listing interface type options.

On transmit, it is responsible for filtering and upsampling signals to a bandwidth and sampling rate appropriate to the DAC.

The Synthesizer can use several Xtals such as Hence the calibration module can adjust for process and temperature variations only when the system is in the normal operating state. Figure depicts the state transition diagram. The AR family supports 2, 3. To assist software flow control, hardware provides eight counters as a credit mechanism.

The MBOX is a service module to handle one of two possible external hosts: The PCU also handles processing responses to the transmitted frame and reporting the transmission attempt results to datadheet DCU. After these signals have been de-asserted, The AR waits for the host power enable signal to be asserted by the external host processor.

Pin Descriptions This section contains a listing of the signal descriptions see Table for the BGA package pin outs. It is responsible for modulating data packets in the transmit direction, and detecting and demodulating a6002 packets in the receive direction.

Correlation to know preamble sequences are also done here for weak signal detection.

In deep sleep mode, the voltage supply to the SOC block, which includes the CPU, can be scaled down to save leakage power.

The only resets that stay asserted are given below: The SOC clock comes from a clock divider module which divides the base clock by a programmable value. When the XTENSA core makes a read request, all buffered write requests are first completed in order to maintain data integrity.

A 3V level is required to control front-end components like xPA or a switch, which are made of semiconductors requiring 2. A block diagram is shown in Figure Building on the advanced performance and features of the AR family, the compact size and low power consumption of this single chip design make it an ideal vehicle for adding WLAN to hand-held and other battery-powered consumer at6002 devices. System includes external PA. AR chips li Pr e in m ary th: Datasgeet Registers ero h Biasing nf Co s Typically, this DCU is the one associated with beacons.

The baseband programmable gain filter is shared between the 2G and 5G paths. The counters may count messages, memory buffers, packets, or any unit that software defines. The lower 2 KB of address space must map all interface registers. The flow control of dtasheet four mailboxes must be managed by software.

All interrupts can be masked by control registers. It has three interfaces:
