• New start up modes allow the PCMCIA Card Information Structure to be initialized from a serial EEPROM. This allows firmware to be downloaded from the host, eliminating the parallel Flash memory device. • Firmware can be loaded from serial Flash memory. • Direct attachment to a typical x16 SRAM using five control signals (RAMCS_, MOE_, MWEL_, MLBE_, and MUBE_). • Low frequency crystal oscillator to maintain time and allow baseband clock source to power off during sleep mode. • Improved performance of internal WEP engine. • On-chip execution can now be viewed while in debug mode. • Independent programmable cycle timing for external chip selects allows attachment of slow memory devices without compromising higher speed instruction execution. • Pinout is backward compatible with HFA3841. • IEEE802.11 Standard Data Rates: 1, 2, 5.5 and 11MbpsPart of the Intersil PRISM Wireless LAN Chip Set • Full Implementation of the MAC Protocol Specified in IEEE Standards 802.11-1999 and 802.11b • PCMCIA Host Interface Supports Full 16-Bit Implementation of PC Card 16 (1995), also ISA PNP with Additional Chip • Host Interface Provides Dual Buffer Access Paths • External Memory Interface Supports up to 4M bytes RAM • Internal Encryption Engine Executes IEEE802.11 WEP • Low Power Operation; 25mA Active, 8mA Doze, <1mA Sleep • Operation at 2.7V to 3.6V Supply • 5V Tolerant Host Interface Input/Outputs • 128 Pin LQFP Package Targeted for Type II PC Cards • IEEE802.11 Wireless LAN MAC Protocol Firmware and Microsoft® Windows® Software Drivers • Pin for Pin Replacement for the HFA3841 Supporting all Functions and operations of the HFA3841  |
