Unit
• Switching ON/OFF procedures :
Switching on:
- The signal “NRESET” on the host interface is forced to a logical zero value by host until the supply voltage
reached its nominal value.
During this phase no component on the module is supplied.
- The host switch its signal “NRESET” to a logical one value allowing the module to turn on its supply.
- After 280ms, the supply gets stabilized and then triggers the start of the ASIC
- 100ms is necessary for the ASIC to start and give execution to the embedded software that will turn the module
into a permanent “active mode”
Switch off through software:
- The host sends the "sleep” AT command
- The ASIC disconnects any BT link
- The ASIC sends the "sleep acknowledge" AT command allowing the host to switch the reset to a zero logical
value.
- If the host activate the “NRESET” to zero for at least 5 us but no more than 4ms the module will be reset.

P
• VCC:
Supply voltage 3.3V(-0.1V/+0.3V) including tolerances, thermal changes, noise over/under shoot due to
load change and/or car battery voltage change, load dump.
Peak current: 400 mA during switch on (2 ms).
• 1.2V OPTIONAL POWER SUPPLY:
This optional allows lower electrical power consumption of CK5050.
Operating Conditions: Supply Voltage for Logic Core: 1.2V (-0.04V/+0.12V)
