Product Description
• Integrated analog and digital voltage
regulators simplify system design.
The UltimateBlue SiW3500™ is a RF System On Chip (SoC) that combines
a 2.4 GHz transceiver, baseband processor, and protocol stack software for
Bluetooth® wireless technology. Due to its low power CMOS process, the
SiW3500 is ideally suited for applications such as mobile phones, audio
headsets, and other embedded products.
• 50 Ω RF I/O does not need any
additional external impedance
matching components.
• Flexible reference clock source
options including crystal or direct
input from the host platform.
• Internal temperature compensated
transmitter and receiver circuits
deliver consistent performance from
-40° to +85°C.
The SiW3500 integrates an ARM7TDMI processor for software execution
from either internal ROM or external FLASH memory. The standard
SiW3500 ROM contains the Bluetooth lower layer stack software including
the HCI transport driver.
• On-chip ROM software storage with
patch capability.
The SiW3500 is packaged in a 6 x 6 Pb-Free 96-VFBGA that meets RoHS
(Green) requirements. Known Good Die (KGD) is available for special
applications.
Applications
• Mobile phones and smart phones.
• Bluetooth audio headset.
• Bluetooth hands-free kit.
