What this Stellaris MCU brings to a control board
The Texas Instruments LM3S1626-IQR50-A0 is a 32-bit ARM Cortex-M3 microcontroller from the Stellaris series, clocked at 50 MHz with 128 KB of Flash and 32K x 8 of SRAM. It is built for industrial control applications.
50 MHz core — what it handles on the factory floor
Connectivity and peripherals for a distributed I/O node
The peripheral set includes I²C, SPI, SSI, UART/USART, and IrDA. Brown-out detect and POR are built in.
Industrial temperature range — rated for the panel
The -40°C to 85°C operating range covers unheated equipment rooms, outdoor enclosures in temperate climates, and the air flow inside a motor control cabinet. The 64-LQFP package is standard for hand-solder rework or reflow assembly; the 10x10 mm body fits comfortably on a two-layer PCB.
