Product details

80 MHz Cortex-M3 in a 108-BGA — industrial control MCU now obsolete

The LM3S1P51-IBZ80-C5: Peripherals include a brown-out detect/reset, DMA controller, I²S audio interface, POR, PWM, and watchdog timer. Connectivity covers I²C, IrDA, Microwire, QEI (for quadrature encoder inputs), SPI, SSI, and UART/USART — a useful set for a motion-control or sensor-fusion node.

Obsolete — no official replacement on record

The LM3S1P51-IBZ80-C5 lifecycle status is obsolete.

108-ball BGA — rework and inspection considerations

Housed in a 108-LFBGA package with a 10x10 mm body, this is a fine-pitch BGA that requires X-ray inspection for solder-joint integrity after reflow. Surface-mount only.
