The LM3S1138-IBZ50-A2T 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 register is used to select the clock source (e.g., internal oscillator, external crystal, or external clock).
The maximum current consumption of the LM3S1138-IBZ50-A2T is approximately 250 mA at 3.3V and 50 MHz, but this can vary depending on the specific application and operating conditions.
The LM3S1138-IBZ50-A2T 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. The specific implementation details can be found in the datasheet and the StellarisWare library documentation.
The LM3S1138-IBZ50-A2T has a USB interface that can operate at full-speed (12 Mbps) and low-speed (1.5 Mbps) frequencies.
