The 25 MHz ceiling is the core speed; the actual throughput depends on flash wait-state configuration and bus arbitration with the peripheral set. ## 52 I/O, serial comms, and on-chip oscillators The connectivity block includes I²C, SPI, SSI, UART/USART, IrDA, Microwire, and a quadrature encoder interface (QEI) — covering most sensor and actuator links in a control board. An internal oscillator is the clock source; no external crystal is required for the core, though the UART baud-rate accuracy depends on the internal RC tolerance. Brown-out detect, POR, PWM, and a watchdog timer are built in. ## 100-LQFP, industrial temp, 2.25 V to 2.75 V Packaged in a 100-LQFP (14x14 mm body) with a surface-mount footprint. Operating temperature covers -40°C to +105°C (TA), which is the industrial-plus band — suitable for motor-drive enclosures, outdoor telecom, and under-hood automotive-adjacent environments where the ambient sees 85°C and the die rises another 20°C.","metaTitle":"LM3S1620-EQC25-A2T TI Stellaris ARM Cortex-M3 MCU, 25MHz","metaDescription":"Texas Instruments LM3S1620-EQC25-A2T Stellaris ARM Cortex-M3 MCU, 25MHz, 128KB Flash, 32KB RAM, 100-LQFP.
