For existing BOM lines, this part is sourced through independent surplus distribution — quantities are lot-specific and confirmed at RFQ. ## Core parametrics and flash/RAM budget The 512 KB flash is the full program memory — no bootloader carve-out to account for, so the firmware image can use the entire block. The 96 KB RAM split leaves room for a moderate RTOS heap plus stack without external memory. The connectivity block covers CANbus, I²C, IrDA, LINbus, Microwire, QEI, SPI, SSI, UART/USART, and USB OTG — enough serial interfaces for most industrial control or sensor hub designs without external bridge chips. The 16-channel 12-bit ADC provides analog front-end capability without an external converter. ## BGA package and board integration Housed in a 108-LFBGA package with a supplier device package of 108-BGA (10x10 mm). The 0.80 mm ball pitch is manageable on a 4-layer board with standard via-in-pad techniques. Surface-mount only — no through-hole option.","metaTitle":"TI LM3S5D51-IBZ80-A1 Cortex-M3 MCU, 80MHz, 512KB Flash","metaDescription":"Texas Instruments LM3S5D51-IBZ80-A1 Stellaris ARM Cortex-M3 MCU. 80MHz, 512KB flash, 96KB RAM, 108-BGA.
