The 100-LQFP package (14x14 mm body) provides 52 GPIOs for peripheral interfacing. Serial interfaces include I²C, SPI, SSI, UART/USART, IrDA, and Microwire — covering most sensor, display, and transceiver links common in embedded control. The Quadrature Encoder Interface (QEI) handles motor position feedback directly, saving an external decoder. On-chip peripherals include a brown-out detect and reset circuit, a power-on reset (POR), a PWM module for drive signals, and a watchdog timer (WDT) for system supervision. The core runs from a single 2.25 V to 2.75 V supply rail — a 2.5 V nominal rail with ±10 % tolerance covers the range. The 32-bit Cortex-M3 architecture delivers a deterministic interrupt response suitable for real-time control loops. ## Lifecycle — obsolete, sourced to order Texas Instruments lists the LM3S1620-EQC25-A2 as Obsolete. No official successor or pin-compatible replacement is recorded in the manufacturer's lifecycle documentation.","metaTitle":"TI LM3S1620-EQC25-A2 ARM Cortex-M3 MCU, 25 MHz, 128 KB Flash","metaDescription":"Texas Instruments LM3S1620-EQC25-A2, Stellaris ARM Cortex-M3 MCU, 25 MHz, 128 KB flash, 32 KB SRAM, 100-LQFP.
