Features:
* 128-Pin LQFP with ‘Green’ package
* State machine implementation without external memory (RAM, flash) requirement
* complies with IEEE 802.11a/b/g standards
* supports descriptor-based buffer management
* Integrated Wireless LAN MAC and Direct Sequence Spread Spectrum/OFDM Baseband Processor in one chip
* Enhanced signal detector, adaptive frequency domain equalizer, and soft-decision Viterbi decoder to alleviate severe multipath effects
* Processing Gain compliant with FCC
* On-Chip A/D and D/A converters for I/Q Data, AGC, and Adaptive Power Control
* Supports both transmit and receive Antenna Diversity
* Data rates of 1, 2, 5.5, 6, 9, 11, 12, 18, 24, 36, 48, and 54Mbps
* Supports 40MHz OSC as the internal clock source. The frequency deviation of the OSC must be within 25 PPM on ieee 802.11g and 20 PPM on ieee 802.11a
* IEEE 802.11g protection mechanisms for both RTS/CTS and CTS-to-self
* Burst-mode support for dramatically enhanced throughput
* DSSS with DBPSK and DQPSK, CCK modulations and demodulations supported with long and short preamble
* OFDM with BPSK, QPSK, 16QAM and 64QAM modulations and demodulations supported with rate compatible punctured convolutional coding with coding rate of 1/2, 2/3, and 3/4
* Efficient IQ-imbalance calibration, DC offset, phase noise, frequency offset and timing offset compensation reduce analog front-end impairments
* Selectable digital transmit and receiver FIR filters provided to meet transmit spectrum mask requirements and to reject adjacent channel interference
* Programmable scaling both in transmitter and receiver to trade quantization noise against the increased probability of clipping
* Fast receiver Automatic Gain Control (AGC) & antenna diversity functions
* Complies with WMM, 802.11e, and CCX specifications
* Complies with 802.11h, 802.11i, 802.11j specifications
* Hardware-based IEEE 802.11i encryption/decryption engine, including 64-bit/128-bit WEP, TKIP, and AES
* Supports Wi-Fi alliance WPA and WPA2 security
* Contains two large independent transmit and receive FIFO buffers
* Advanced power saving mode when the LAN and wakeup function are not used
* Uses 93C46 (64*16-bit EEPROM) or 93C56 (128*16-bit EEPROM) to store resource configuration and ID parameter data
* LED pins for various network activity indications
* Six GPIO pins supported
* Supports digital loopback capability on both ports
* Scatter and gather operation
* Complies with USB Specification 2.0
o Supports Full-speed (12Mbps) and High-speed (480Mbps)
* Embedded standard 8051 CPU with enhanced features:
o Four cycles per instruction
o Variable clock speed cuts power consumption
* Supports 9 endpoints:
o 64-Byte buffer for control endpoint
o Two 512-Byte buffers for bulk IN endpoint
o Seven 512-Byte buffers for bulk OUT endpoint
