Product details

Texas Instruments has marked the LM3S8970-EQC50-A2 as Obsolete.

Core parametrics and memory fit

The 256 KB Flash is sufficient for moderate application code, while the 64 KB SRAM supports real-time data buffering and stack-heavy RTOS tasks.

Connectivity and peripheral set

The device integrates CANbus, Ethernet, I²C, IrDA, Microwire, SPI, SSI, and UART/USART interfaces, covering a broad range of industrial and networked applications. On-chip peripherals include brown-out detect, POR, PWM, and watchdog timer.

Supply voltage and clocking

An internal oscillator is provided, reducing external component count for clock generation.

Frequently asked questions
