That means the part is still available for existing production but is no longer targeted for new designs. The last-time-buy window may be open; we source it through authorized and independent channels against an RFQ. ## Core and memory — 50MHz Cortex-M3 with 256KB flash The LM3S2948-IQC50-A2 is built around a 32-bit ARM Cortex-M3 core running at 50MHz. On-chip memory includes 256KB of flash (256K x 8) and 64K x 8 of SRAM. For a Cortex-M3 part of this vintage, the 64KB RAM gives headroom for a modest RTOS heap and application stack alongside the peripheral buffers. ## Peripherals and connectivity — CAN, UART, SPI, I²C, and more The peripheral set includes CANbus, I²C, IrDA, Microwire, SPI, SSI, and UART/USART interfaces. It also integrates an 8-channel 10-bit ADC, PWM outputs, brown-out detect, POR, and a watchdog timer. With 52 GPIOs in a 100-LQFP package, this MCU suits industrial control or sensor hub applications requiring multiple serial buses and mixed-signal capability. ## Package and board integration — 100-LQFP (14x14 mm) The device is supplied in a 100-lead LQFP package with a 14x14 mm body. Supply voltage range is 2.25V to 2.75V. The 0.5 mm pitch of the LQFP-100 demands a multi-layer PCB for clean fan-out of the inner rows.","metaTitle":"TI LM3S2948-IQC50-A2 Stellaris ARM Cortex-M3, 50MHz","metaDescription":"Texas Instruments LM3S2948-IQC50-A2 Stellaris ARM Cortex-M3 MCU, 50MHz, 256KB Flash, 64KB RAM, NRND.
