The LM3S2616-IQR50-A0 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) or the internal RC oscillator. The PLL can be configured to use an external crystal or an external clock source. The internal RC oscillator can be used as a clock source, but it is not as accurate as an external crystal.
The maximum frequency of the CPU is 50 MHz, but it can be adjusted using the PLL or the clock divider.
The LM3S2616-IQR50-A0 has 256 KB of flash memory available for programming.
Yes, the LM3S2616-IQR50-A0 can operate from a 3.3V power supply, but it is recommended to use a voltage regulator to ensure a stable voltage supply.
