BlueCore™4
implements Bluetooth® 2.0+EDR (Enhanced Data Rate). It can deliver
data rates up to 3-times faster than current Bluetooth devices -
and lower power consumption. BlueCore4 is backwards compatible with
existing v1.1 and v1.2 devices:
BlueCore4-Ext - a complete single-chip
Bluetooth solution with onchip microcontroller, and an external
Flash memory interface for general-purpose use and development/prototyping.
VFBGA packaging. Ideal for high-datarate/multi-link PC applications.
• EDR compliant, backwards compatible with v1.1/1.2 - including
eSCO
• External Flash memory interface
• BGA packaging
• Ideal for high-datarate/multi-link PC applications
