• Power On/Off Sequences (Initial Power ON/Complete Power OFF)
When Powering On
Note1: Although it is possible to turn on or off the 1.5-V and 3.3-V power supply rails simultaneously, it may cause
Note2: In the power-on sequence, the 3.3-V power supply rails must not be turned on before the ones of 1.5-V. In the
circuit blocks first and then to the external circuit blocks. Also, in the complete power-off
sequence, power must be removed from the external circuit blocks and then from the
on-chip circuit blocks.
Notes on Power-On/Off Sequences
As shown below, in the initial power-on sequence, power must be supplied to the on-chip
external pins to temporarily become unstable. Therefore, if there is any possibility that this would affect
peripheral devices connected with the TMP92CF26A, external power supplies should be turned on or off while
the internal power supplies are stable, as indicated by the heavy lines in the diagram above.
power-off sequence, the 3.3-V power supply rails must not be turned off after the ones of 1.5-V.
Power-on
(DVCC1A, DVCC1B, DVCC1C) → (DVCC3A, DVCC3B, AVCC)
Power-off
(AVCC, DVCC3A, DVCC3B) → (DVCC1C, DVCC1B, DVCC1A)
Power should rise and stabilize
within 100 ms.
High-frequency Oscillation Stabilizing Time
＋20 system clock cycles

Power Cut Mode (PMC)
Power should fall and stabilize
within 100 ms.
When Powering Off
3.3-V rails should be turned
off first, followed by the 1.5-V
rails.
