The LM3S800 integrates I²C, SPI, SSI, Microwire, and UART/USART serial interfaces — enough to talk to a temperature sensor, a motor encoder, and a host controller on one chip. The PWM and WDT peripherals are there for motor-drive timing and watchdog supervision, though the PWM resolution and timer depth are the usual Cortex-M3 SysTick and general-purpose timers.
There is no discontinuation notice or last-time-buy window in effect.
Within the same Stellaris LM3S800 family, the LM3S800-EQN50-C1 is the same silicon in the same 48-LQFP package — functionally identical but with a different ordering code suffix that may carry a different temperature or packaging option. Verify the suffix differences against your BOM requirements before substituting.
