4.7 Timing and Switching Characteristics
4.7.1 Device Power Supply
The power-management hardware and software algorithms of the TI Bluetooth HCI module provide
significant power savings, which is a critical parameter in an MCU-based system.
The power-management module is optimized for drawing extremely low currents.
4.7.1.1 Power Sources
The TI Bluetooth HCI module requires two power sources:
• VDD_IN: main power supply for the module
• VDD_IO: power source for the 1.8-V I/O ring
The HCI module includes several on-chip voltage regulators for increased noise immunity and can be
connected directly to the battery.
4.7.1.2 Power Supply Sequencing
The device includes the following power-up requirements (see Figure 4-1):
• nSHUTD must be low. VDD_IN and VDD_IO are don't-care when nSHUTD is low. However, signals
are not allowed on the I/O pins if I/O power is not supplied, because the I/Os are not fail-safe.
Exceptions are SLOW_CLK_IN and AUD_xxx, which are fail-safe and can tolerate external voltages
with no VDD_IO and VDD_IN.
• VDD_IO and VDD_IN must be stable before releasing nSHUTD.
• The slow clock must be stable within 2 ms of nSHUTD going high.
The device indicates that the power-up sequence is complete by asserting RTS low, which occurs up to
100 ms after nSHUTD goes high. If RTS does not go low, the device is not powered up. In this case,
ensure that the sequence and requirements are met.
