The LM3S1607 can operate from -40°C to 85°C, but the industrial temperature range is -40°C to 105°C.
The LM3S1607 can use an internal oscillator, an external crystal oscillator, or an external clock source. The clock source is configured using the CLKCFG register.
The maximum frequency of the CPU is 50 MHz, but it can be adjusted using the PLL (Phase-Locked Loop) and the clock divider.
The ADC on the LM3S1607 is a 12-bit successive approximation ADC. It can be configured using the ADCCTL register and triggered using the ADCTrig register.
Yes, the LM3S1607 has an external memory interface that supports up to 16-bit data bus and can be used to interface with external memory devices such as SRAM, NOR flash, and NAND flash.
