Product details

50 MHz Cortex-M3 with 32 KB Flash — what it covers

The LM3S617-IQN50-C2T: That core speed and memory footprint suit control-loop and sensor-fusion tasks in industrial automation, motor drives, and building controllers — applications where a 32-bit pipeline handles PID math or Modbus frames without the overhead of a larger part. The 30 I/O pins, six 10-bit ADC channels, and serial interfaces (Microwire, SPI, SSI, UART/USART) give it the peripheral set for mixed-signal feedback and multi-drop communication.

The 48-LQFP (7x7 mm) package is a standard low-profile footprint — reworkable with hot air and compatible with most automated optical inspection setups.

Frequently asked questions

Is LM3S617-IQN50-C2T obsolete?

Existing production can still source it, but new designs should migrate to a current Stellaris or TM4C series part.

Can LM3S617-IQN50-C2T be used in new designs?

TI classifies it as NRND, so it is not recommended for new designs. Use it only for sustaining existing production or for a bridge supply while qualifying a current-generation alternative.
