6.3 Recommended Operating Conditions

over operating free-air temperature range (unless otherwise noted)

			MIN	NOM	MAX	UNIT
V_(VDD)	Core power 1.1 V (main 1.1 V)		1.045	1.10	1.155	V
V_(VDDLP12)	Unused	See ⁽²⁾	1.045	1.10	1.155	V
V_(VCC18)	All 1.8-V I/O power: (1.8-V power supply for all I/O pins except the host or parallel interface and the SPI flash interface. This includes RESETZ, PARKZ LED_SEL, CMP_OUT, GPIO, IIC1, TSTPT, and JTAG pins.)		1.64	1.80	1.96	V
V_{(VCC_INTF)}	Host or parallel interface I/O power: 1.8 to 3.3 V (includes IIC0, PDATA, video syncs, and HOST_IRQ pins)	See ⁽¹⁾	1.64	1.80	1.96	V
			2.28	2.50	2.72
			3.02	3.30	3.58
V_{(VCC_FLSH)}	Flash interface I/O power: 1.8 V to 3.3 V	See ⁽¹⁾	1.64	1.80	1.96	V
			2.28	2.50	2.72
			3.02	3.30	3.58
V_{(VDD_PLLM)}	MCG PLL 1.1-V power	See ⁽³⁾	1.025	1.100	1.155	V
V_{(VDD_PLLD)}	DCG PLL 1.1-V power	See ⁽³⁾	1.025	1.100	1.155	V
T_A	Operating ambient temperature ⁽⁴⁾		–30		85	°C
T_J	Operating junction temperature		–30		105	°C

(1) These supplies have multiple valid ranges.

(2) It is recommended that VDDLP12 be tied to the VDD rail.

(3) The minimum voltage is lower than other 1.1-V supply minimum to enable additional filtering. This filtering may result in an IR drop across the filter.

(4) The operating ambient temperature range assumes 0 forced air flow, a JEDEC JESD51 junction-to-ambient thermal resistance value at 0 forced air flow (R_θJA 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 R_θJA. Thus, maximum operating ambient temperature varies by application.

T_A(min) = T_J(min) – (P_S(min) × R_θJA) = –30°C – (0.0 W × 28.8°C/W) = –30°C
T_{a_max} = T_{j_max} – (P_{d_max} × R_θJA) = +105°C – (0.348 W × 28.8°C/W) = +95.0°C
