LM3S1439-IQC50-A2 Frequently Asked Questions (FAQ)
-
The LM3S1439-IQC50-A2 can operate from -40°C to 85°C (industrial temperature range) and from -40°C to 105°C (extended temperature range) with some limitations.
-
The clock source can be configured using the PLL (Phase-Locked Loop) and the OSC (Oscillator) registers. The PLL can be used to multiply the clock frequency, and the OSC can be used to select the clock source (e.g., internal oscillator, external crystal, or external clock).
-
The maximum current consumption of the LM3S1439-IQC50-A2 is approximately 250 mA at 50 MHz with all peripherals enabled and running at maximum frequency.
-
The LM3S1439-IQC50-A2 has several low-power modes, including Sleep, Deep Sleep, and Hibernate. These modes can be entered using the Power Management Controller (PMC) and can reduce power consumption to as low as 10 μA.
-
The USB interface on the LM3S1439-IQC50-A2 can operate at a maximum frequency of 48 MHz.
