Product details

50 MHz Cortex-M3 with 32 KB flash — sizing the control-loop budget

The 32-bit core at 50 MHz gives you roughly 1.25 DMIPS/MHz, so about 62.5 DMIPS peak, which handles sensor fusion or motor commutation at moderate update rates. The 8 KB SRAM is the binding constraint: a 1 KB comms buffer plus a 2 KB stack leaves 5 KB for data arrays, so plan the heap and local variables accordingly.

Industrial temperature range and on-chip peripherals

Two 10-bit ADC channels are adequate for monitoring supply rails or a thermistor, but not for audio or precision measurement.

Package, supply, and footprint notes

Supplied in a 48-VFQFN with exposed pad (7x7 mm VQFN footprint). The 34 general-purpose I/O pins are multiplexed with the peripheral functions, so check the pin assignment in the datasheet for your specific peripheral mix.

Frequently asked questions

What is the flash size of LM3S612-EGZ50-C2?

The program memory is 32 KB (32K x 8) of flash. This is the firmware-storage capacity; the device also has 8 KB of SRAM for runtime data.
