50 MHz Cortex-M3 with 32 KB Flash — what fits and what doesn't
The 32-bit core handles control loops, protocol stacks (I²C, SPI, UART), and PWM generation without a co-processor. The 8 KB SRAM budget limits buffered data to about 2 KB of TCP payload or a modest ADC scan table — so if your application needs a large frame buffer or extensive logging, this part will feel tight.
Industrial temperature and 48-LQFP footprint
The 48-LQFP (7x7 mm) package has 28 general-purpose I/O, an 8-channel 10-bit ADC, and internal oscillator — enough for a sensor hub or motor-drive interface without external clock components.
Sourcing reality for a NRND part
Because the LM3S608 is NRND, the authorized-distributor pipeline is winding down. Independent distribution carries remaining inventory and material from excess stock. Every unit we quote is verified against the manufacturer's marking and date-code consistency — the laser etch on the 48-LQFP body is a fingerprint we check against known-good TI production runs.
