The 128 KB on-chip flash (128K x 8) and 32 KB SRAM (32K x 8) provide enough headroom for a modest control stack — think motor-control firmware with a CANopen stack, or a sensor hub that logs data over UART. ## Peripheral set — CAN, I²C, SPI, UART, PWM The connectivity block includes CANbus, I²C, IrDA, Microwire, SPI, SSI, and UART/USART — enough serial interfaces to talk to a CAN-based drive network, an I²C temperature sensor, and a UART debug console simultaneously. On-chip peripherals also cover brown-out detect, POR, PWM, and a watchdog timer, reducing external supervisor IC count. The internal oscillator eliminates the external crystal for many applications, though the BOM should still budget for a precision source if the CAN or USB timing requires it. ## Industrial temperature — 108-BGA (10x10 mm) The 108-BGA package measures 10x10 mm with a 0.80 mm ball pitch — a 4-layer PCB with via-in-pad or microvia fan-out is recommended for reliable solder joints. A 2.5 V rail is the nominal choice; the regulator must stay within this window across load transients from the flash read current.","metaTitle":"LM3S2620-IBZ25-A2T Texas Instruments ARM Cortex-M3 MCU","metaDescription":"Texas Instruments LM3S2620-IBZ25-A2T Stellaris ARM Cortex-M3 MCU, 25 MHz, 128KB Flash, 32KB RAM, 108-BGA.
