2.2.1 BlueCore04

BlueCore4 is a single chip Bluetooth solution which implements the Bluetooth radio
transceiver and also an on chip microcontroller. BlueCore4 implements Bluetooth®

2.0+EDR (Enhanced Data Rate) and it can deliver data rates up to 3 Mbps.

The microcontroller (MCU) on BlueCore04 acts as interrupt controller and event timer run
the Bluetooth software stack and control the radio and host interfaces. A 16-bit reduced
instruction set computer (RISC) microcontroller is used for low power consumption and
efficient use of memory.

BlueCore04 has 48Kbytes of on-chip RAM is provided to support the RISC MCU and is
shared between the ring buffers used to hold voice/data for each active connection and
the general purpose memory required by the Bluetooth stack.
