Product details

The LM3S608-IGZ50-C2: ARM Cortex-M3 32-bit single-core MCU clocked at 50 MHz, with 32 KB Flash and 8 KB RAM. It has 28 I/O, an 8-channel 10-bit ADC, and serial connectivity covering I²C, SPI, SSI, Microwire, and UART/USART.

32 KB Flash / 8 KB RAM — sizing the firmware footprint

At 32 KB program memory and 8 KB SRAM, this part fits firmware that fits in a single bank — no paging, no external memory interface. That limits the application to lean control loops, bootloaders, or protocol bridges. If your design needs more than 8 KB of variable space or a real-time OS, you are looking at the wrong density tier.

Lifecycle — end-of-life phase, sourced through independent channels

The LM3S608-IGZ50-C2 carries an end-of-life (hot) status. Texas Instruments has discontinued the Stellaris line; production has stopped.

Frequently asked questions

What is the closest pin-compatible alternative to LM3S608-IGZ50-C2?

There is no official pin-compatible drop-in from TI. The TM4C123 series is a functional successor but differs in pinout, peripheral set, and supply voltage tolerance. Verify your board layout before substituting.

What compliance documentation does Texas Instruments provide for LM3S608-IGZ50-C2?

The part is RoHS-compliant per TI's standard declaration. No UL or IEC certification is listed in the available documentation.
