Each GPIO supports the following configurations via software programming: The host and AR CPUs can read and write these counters using ordinary writes or atomic operations. A allowing optimal antenna selection on a per. An on-chip bandgap reference circuit provides the needed voltage and current references based on an external 6. Depending upon the address, the APB request can go to one of the eight places listed below: AR System Block Diagram.
Functional operation under these conditions, or at any other condition beyond those indicated in the operational sections of this document, is not recommended. Because the ADC dynamic range does not span all possible input power levels, an automatic gain control feedback loop is designed into the radio and baseband receive 24 24?
System includes external PA. The SOC clock comes from a clock divider module which divides the base clock by a programmable value. For low power states, the polarity of the switch settings are shown in Table As long as the host status underflow bit is set, any mailbox reads that arrive when the mailbox is empty, return garbage data.

There are four scenarios where the CPU Reset can be asserted: The BB needs this fundamental clock together with several divided versions of it. Transmitter Characteristics for 2. The PLL output is programmable but it will usually run at one of only two frequencies: Figure shows datadheet host interface address map. The AR has an internal calibration module which produces a For the 2 GHz operation, the receiver is comprised of two separate paths: A lower voltage, down to 3.
On receive, the TIM block does all data path processing for time domain related signals. Figure shows the generic SDIO address map. After all clocks are stable and running, the resets to all blocks are 1. Its inputs consist of sleep requests from these modules and its outputs a6002 of clock enable and power ar602 which are used to gate the clocks going to these modules.
It is also possible to hold the CPU in reset until the host clears an internal register.

It encapsulates two major interfaces to the MAC and radio modules. The AR requires 3 power levels, 1. For the 5 GHz operation, the receiver is implemented using the sliding IF topology.
Port shared with the PA.
The AR family includes a highly integrated, front-end module Power Amplifier, Low-Noise Amplifier and RF switchenabling low-cost designs with minimal external components.
The AR baseband module BB is the physical layer controller for the The TSF and other low frequency timers need to be programmed to match this frequency.
If not, an internal regulator can be used. For both 5G and 2G paths, mixers down convert the signal to baseband in-phase I and quadrature-phase Q signals. Pin Descriptions This section contains a listing of the signal descriptions see Table for the BGA package pin outs. The RF performance, data throughput, and power consumption further improve upon the performance of the AR family. Pr in lim e ary th: The AR family supports 2, 3 ry and 4 wire Bluetooth coexistence protocols with a advanced algorithms for predicting channel in usage by the co-located Bluetooth transceiver.
The CPU may continue to ar6020 held in reset under some circumstances until its reset is cleared by an external pin or when the host clears a register. Advanced architecture and protocol techniques save power during sleep, stand-by and active states.
