Each GPIO supports the following configurations via software programming: There are four scenarios where vatasheet CPU Reset can be asserted: Absolute maximum ratings are those values beyond which damage to the device can occur.

Figure shows the generic SDIO address map. Radio Functional Block Diagram 3. The BB needs this fundamental clock together with several divided versions of it. The analog block requires 1.

Pin Descriptions This section contains a listing of the signal descriptions see Table for the BGA package pin outs. This is a bit RISC core with datxsheet 5-stage pipeline and with bit and bit instruction encoding. Weak signal detection will correlate against known preamble sequences when gain changes are not occurring. Minimum clearance of 0.

Decisions on rate and output power are directed by the MAC through the use of transmit data headers. The PLL output is programmable but it will usually run at one of only two frequencies: This is done by comparing the relative preamble correlation power for the two protocol types. Messages include packets, control messages, or any software-defined communication. The host reads the ready bit and can now send function commands to the AR See Figure for details. For the 5 GHz operation, the receiver is comprised of a low noise amplifier LNA followed by a variable gain amplifier VGAa radio frequency RF mixer, an intermediate frequency IF mixer, and a baseband programmable gain filter.

The I and Q signals are low-pass filtered and amplified by the baseband programmable gain filter controlled by digital logic. It then begins communicating with this host.

Virtual and Physical Memory Mapping 1. Like on transmit, this includes all filtering and sample rate conversions necessary for processing the incoming signal. The Atheros logo is a registered trademark of Atheros Communications, Ar0602. Control Registers ero h Biasing nf Co s Strong signal detection simply looks for large changes in incoming signal strength, and will assume that these “strong signals” are most likely packets to try and decode. A block diagram is shown in Figure The counters may count messages, memory buffers, packets, or any unit that software defines.

Radio The AR transceiver consists of four major functional blocks see Figure 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. When dztasheet XTENSA core makes a read request, all buffered write requests are first completed in order to maintain data integrity.

It can be running at any similar low frequency. Its inputs consist of sleep requests from these modules and its outputs consists of clock enable and power signals which are used to gate the clocks going to these modules.

Typically, this DCU is the catasheet associated with beacons. For the 2 GHz operation, the transmitter is comprised of the programmable reconstruction filter, datashheet direct conversion mixer, a preamplifier and a PA. The others are hardware interrupts for various configurations.

Nonetheless, this document is subject to change without notice. The least significant bit of the register is ANTA. Maximum rating for signals follows the supply domain of the signals. Frame transmission begins with the QCUs, which are responsible for managing the DMA of frame data from the host via the HIU, and for determining when a frame is available for transmission. Receiver Characteristics for 2.

This CPU has four interfaces: This feedback loop recognizes when input signals seen by the ADC are either too small or too large, or even saturated.

Once the DCU gains access to the channel, it passes the frame to the PCU, which manages the final details of sending the frame to the baseband logic. On power up or 22 22? The high speed crystal or oscillator is disabled.

Boot code in the ROM first detects the presence of an external host. Table shows pin settings for mode configuration, sampled during reset. For applications where the AR shares an antenna with another wireless chip, ANTD is reserved for controlling the shared antenna switch. The MBOX is a service module to handle one of two possible external hosts: Building on the advanced AR Features 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 datasheeet other battery-powered consumer adtasheet devices.
