TAOperating ambient temperature(5)–3085°C
TJOperating junction temperature–30105°C
(1) These supplies have multiple valid ranges.
(2) The minimum voltage is lower than other 1.1V supply minimum to enable additional filtering. This filtering may result in an IR drop across the filter.
(3) It is recommended that VDDLP12 rail is tied to the VDD rail. The DSI LP supply (VDDLP12) is only used for read responses from the controller which are not supported. Because of this, a separate 1.2V rail is not required. If a separate 1.2V supply is already being used to power this rail, a voltage tolerance of ±6.67% is allowed on this separate 1.2V supply.
(4) When the DSI-PHY LP supply (VDDLP12) is fed from a supply separate from VDD, the VDDLP12 power must sequence ON after the 1.1V core supply and must sequence OFF before the 1.1V core supply.
(5) The operating ambient temperature range assumes 0 forced air flow, a JEDEC JESD51 junction-to-ambient thermal resistance value at 0 forced air flow (RθJA at 0 m/s), a JEDEC JESD51 standard test card and environment, along with minimum and maximum estimated power dissipation across process, voltage, and temperature. Thermal conditions vary by application, and this affects RθJA. Thus, maximum operating ambient temperature varies by application.
  • Ta_min = Tj_min – (Pd_min × RθJA) = –30°C – (0.0 W × 30.3°C/W) = –30°C
  • Ta_max = Tj_max – (Pd_max × RθJA) = +105°C – (0.348 W × 30.3°C/W) = +94.4°C
