The connectivity block includes I²C, SPI, SSI, UART/USART, IrDA, Microwire, and a quadrature encoder interface (QEI) — the QEI is useful for closed-loop motor speed/position feedback without an external decoder. On-chip peripherals — brown-out detect/reset, power-on reset, PWM, and watchdog timer — reduce the external supervisor IC count. ## Package and supply rails The 108-ball LFBGA package measures 10x10 mm (supplier device package 108-BGA). The 0.50 mm ball pitch demands a multi-layer PCB for fan-out — a four-layer board with a dedicated ground plane is typical for signal integrity at 50 MHz. The core and I/O share the same supply, so no separate VDDIO rail is needed. ## Industrial temperature grade The 108-BGA package is MSL-3 typical for lead-free solder reflow; a moisture bake before rework is recommended if the floor life has been exceeded. ## Lifecycle status — NRND Texas Instruments lists the LM3S1960-IBZ50-A2T as NRND (Not Recommended for New Designs). The part is still available for existing production BOMs, but new designs should evaluate the current Stellaris or Tiva C Series portfolio for a migration path.","metaTitle":"TI LM3S1960-IBZ50-A2T MCU, 50 MHz Cortex-M3, 256KB Flash","metaDescription":"Texas Instruments LM3S1960-IBZ50-A2T Stellaris ARM Cortex-M3 MCU, 50 MHz, 256KB Flash, 64KB RAM, 108-BGA.
