LM3S1958-IQC50-A2 Frequently Asked Questions (FAQ)
-
The LM3S1958-IQC50-A2 can operate from -40°C to 85°C (industrial temperature range) and from -40°C to 105°C (extended temperature range) with reduced performance.
-
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 or clock source.
-
The maximum current consumption of the LM3S1958-IQC50-A2 is approximately 350 mA at 50 MHz with all peripherals enabled and running at maximum frequency.
-
The LM3S1958-IQC50-A2 can be programmed using the IAR Embedded Workbench, Keil µVision, or the Texas Instruments Code Composer Studio (CCS) development environment. The microcontroller can be programmed using the JTAG interface or the In-Circuit Serial Programming (ICSP) interface.
-
The LM3S1958-IQC50-A2 has 256 KB of flash memory available for program storage.
