The LM3S8G62-IBZ80-A2 is a Stellaris ARM Cortex-M3 MCU from the 8000 series, built around a 32-bit single-core processor running at 80 MHz.
Industrial temperature range and BGA package
The BGA footprint saves board area versus a QFP, but plan for a multi-layer PCB to route the signals cleanly.
No official successor part number appears in the lifecycle record. Production has ended; the only available stock is new-old-stock or surplus inventory held by independent distributors. If you need a drop-in replacement, there is no pin-compatible direct alternate from TI's current portfolio; a redesign with a newer Cortex-M4 or M7 part is the practical path.
Peripheral set and data conversion
On-chip peripherals include brown-out detect, DMA, motor-control PWM, watchdog timer, and a 16-channel 12-bit ADC. Connectivity covers CAN, Ethernet, I²C, IrDA, LIN, Microwire, QEI, SPI, SSI, and UART/USART — enough interface variety to tie into most industrial fieldbuses without external bridge chips.
