RDA5990P SIP For WLAN/BLUETOOTH/FM Radio Tuner Rev.1.3–04.2012 1 General Description RDA5990P integrates RDA5990,PowerAmplifier and antenna switch into one chip and is optimized for mobile applications. WLAN, Bluetooth and FM can work simultaneously and independently, with low power consumption levels target to battery powered devices. For the highest integration level, the required board space has been minimized and customer cost has been reduced. Manufacturers can easily and fast integrate RDA5990P on their product to enable a rapid time to market. RDA5990P uses a compact 7*7mm 48-pin QFN package. 1.1 WLAN Features CMOS single-chip fully-integrated radio, PHY and MAC Single-band 2.4GHz IEEE 802.11b/g Support WEP, WPA/WPA2, WAPI WAPI hardware accelerated Wi-Fi Protected Setup support Wi-Fi Peer to Peer support Industry Standard QoS schemes(802.11e,WMM) support Shared Bluetooth and WLAN receive signal path Shared Bluetooth and WLAN crystal Build-In IEEE 802.15.2 coexistence scheme Support host interfaces: SDIO v1.2, SPI Advance sleep and wakeup for power saving Smallest WLAN solution footprint No external EEPROM needed Support battery voltage range from 3v to 5v 1.2 Bluetooth Features CMOS single-chip fully-integrated radio and baseband Compliant with Bluetooth 2.1 + EDR specification Bluetooth Piconet and Scatternet support ARM7-based mcu with on-chip ROM and RAM Meet class 2 and class 3 transmitting power requirement, support class1 operation with external power amplifier Provides +10dbm transmitting power NZIF receiver with -90dBm sensitivity Battery power supply directly with internal LDO Support DCXO with internal oscillator circuit Up-to 4Mbps high speed UART HCI support Support AFH Build-In 3-wire WIFI Co-existence handshake signals Low power consumption Minimum external component Internal 32k LPO.
