The LM3S5632-IQR50-A0T 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 LM3S5632-IQR50-A0T is approximately 250 mA at 50 MHz with all peripherals enabled, but this can vary depending on the specific application and usage.
The LM3S5632-IQR50-A0T has several low-power modes, including Sleep, Deep Sleep, and Hibernate. These modes can be entered using the Power Management Controller (PMC) and can help reduce power consumption when the microcontroller is not actively processing data.
The LM3S5632-IQR50-A0T has a USB interface that supports full-speed (12 Mbps) and low-speed (1.5 Mbps) modes, but it does not support high-speed (480 Mbps) mode.
