The LM3S2608-IBZ50-A2 is a Texas Instruments Stellaris ARM Cortex-M3S 2000 microcontroller built around a 32-bit ARM Cortex-M3 core clocked at 50 MHz. The part is designated NRND (Not Recommended for New Designs) by Texas Instruments.
108-BGA footprint and operating range
Housed in a 108-LFBGA package (10x10 mm body, 108-BGA supplier device package), the LM3S2608-IBZ50-A2 is surface-mount only. The 52 general-purpose I/O lines connect to a peripheral set that includes CANbus, I²C, IrDA, Microwire, SPI, SSI, and UART/USART interfaces. On-chip data conversion is handled by an 8-channel, 10-bit ADC.
On-chip oscillators and system monitoring
The part integrates brown-out detect/reset, POR, PWM, and a watchdog timer — these peripherals reduce external supervisor circuitry for industrial control or sensor-node applications.
