The LM3S1960-EQC50-A2T: With 60 general-purpose I/O lines, the MCU can interface directly with a mix of sensors, actuators, and displays without external port expansion. On-chip connectivity includes I²C, SPI, SSI, UART/USART, IrDA, and a Quadrature Encoder Interface (QEI) — the QEI is a dedicated peripheral for reading incremental rotary encoders in motion-control applications. Additional integrated peripherals — brown-out detect/reset, POR, PWM, and watchdog timer — reduce the need for external supervisory and timing ICs in a compact 100-LQFP (14x14 mm) package.
Texas Instruments lists the LM3S1960-EQC50-A2T as obsolete. For existing designs that require this exact order code, procurement must go through independent surplus or broker channels.
