Frequently asked questions
Can all 52 I/O pins be used freely, or are some reserved for the core functions?
The LM3S1150 provides 52 I/O at the package level, with pin multiplexing assigning each peripheral function (UART, SPI, I²C, QEI, PWM) to specific pins. Reserved pins for debug (SWD) and power/ground are standard. The full mux map is in the device data sheet — verify the specific UART routing for your serial bridge before locking the I/O budget.
The IQC50 suffix — does this indicate automotive grade or a special screening level?
I = industrial temperature range (-40°C to 85°C), Q = TI quality grade, 50 = 50 MHz speed bin. The A2T suffix designates Tape & Reel packaging. Neither suffix encodes AEC-Q100 automotive qualification. This is an industrial-grade commercial part, not automotive-screened.
