The industrial temperature grade (-40°C to 85°C) and the 2.25 V to 2.75 V supply range suit it for factory-floor controllers, pump/motor drive communication bridges, and outdoor telecom line cards where the ambient envelope stays within that range. ## 128 KB Flash, 64 KB SRAM — sizing the firmware and data budget 128 KB Flash and 64 KB SRAM fit a USB device stack, CANopen or Modbus RTU protocol layer, and a control loop. The LM3S5752-IQR50-A0T carries an EOL hot lifecycle status, meaning the manufacturer has initiated end-of-life transition. ## Connectivity peripherals — which interfaces are on this die Peripherals include USB OTG, CAN, I²C, SPI, SSI, UART, IrDA, and a 6-channel 10-bit ADC. ## Package and temperature grade — board fit and environment 64-LQFP package with 10x10 mm body, surface-mount, -40°C to 85°C operating range, 2.25 V to 2.75 V supply.","metaTitle":"LM3S5752-IQR50-A0T Stellaris ARM Cortex-M3 MCU, 50MHz","metaDescription":"LM3S5752-IQR50-A0T 32-bit ARM Cortex-M3 MCU, 50MHz, 128KB Flash, 64KB SRAM, USB OTG+CAN, -40~85°C, 64-LQFP.
