MOTOROLA Hardware 4-13
Motorola Confidential Proprietary, NDA Required / Preliminary
• Audio input: 65m Vpp
• Audio output: 1.6 Vpp, modular jack 4/4 connector
The following table shows the current consumption measurements of the circuits of the MC71000
Bluetooth Baseband Controller and MC13180 Bluetooth Low Power Wireless Data Transceiver ICs.
Note that the table contains typical values.
4.4.1 Power Supply
The board is fed with power from on-board standard regulators.
The on-board power supply regulators should be fed with the supply provided, which generates the
following voltages for the board:
•1.85 V
•2.65 V
•3.3V
4.4.2 Reset Circuit
The board includes a push button for full system reset of the MC71000 and all peripherals.
4.4.3 Clocks
The clocks in the system are as follows:
• Sleep mode clock: 32.768 kHz.
• Active mode clock: 24 MHz from MC13180 radio module
The MC71000 includes an internal oscillator circuit for the 32.768 kHz sleep mode clock. Only an external
crystal and a few other components are needed.
