5.2. Operating Conditions

TC3567C can operate normally with proven quality under the operating ranges. Any diversion from the operating ranges may

cause false operation. Thus, please make sure application design to comply these operating ranges.

Note1: The internal CPU powers on when the operating voltage rises to the minimum value of the VBAT operating voltage 1.

However, please pay attention that the minimum voltage of the VBAT operating voltage 2 is required for the reading and

writing operation of the flash ROM as indicated in the Note 2.

Note2: For reading and writing operation to the flash ROM in the digital block, the power in the range of VBAT operating voltage 2

should be supplied. In the booting process, please release RESET after the voltage rises to the minimum value (1.9 V)

because of accessing to the flash ROM to confirm the existence of applications. Moreover, in case of operating in the

User-App mode or driving till the under voltage detection turns off the operation, please pay attention to the relation between

R/W operation to the flash ROM and the voltage.

Note3: Please refer to other documents (application note) for our connection examples.

Please do not input external power supply and do connect external capacitors to VDDIOFQ because they are supplied by

the internal LDO.
