The Texas Instruments LM3S613-IQN50-C2 is a 32-bit ARM Cortex-M3 microcontroller from the Stellaris 600 series, clocked at 50 MHz. It carries 32 KB of Flash program memory and 8 KB of SRAM.
The LM3S613-IQN50-C2 is officially obsolete per Texas Instruments. No last-time-buy window remains open; the part is available only through independent surplus and broker channels.
No. Because the LM3S613-IQN50-C2 is obsolete, it should not be selected for new designs. Use an active Cortex-M3 or Cortex-M4 MCU with similar peripheral set and package.
The LM3S613-IQN50-C2 uses a 48-pin LQFP package. The pinout is documented in the Texas Instruments datasheet for the Stellaris LM3S613 device. Key signals include 32 GPIOs, a 4-channel 10-bit ADC, and serial interfaces on dedicated pins.
