On-chip program memory is 384 KB of flash, paired with 96 KB of SRAM — the 96K x 8 entry maps to 96 KB of byte-addressable RAM. For a Cortex-M3 class device, the 1:4 flash-to-RAM ratio is generous, suiting applications that keep a moderate-sized frame buffer or communication stack in SRAM. The peripheral list includes CANbus, EBI/EMI, I²C, IrDA, Microwire, QEI, SPI, SSI, and UART/USART — a broad mix that covers industrial fieldbus (CAN), external memory expansion (EBI/EMI), and sensor interfaces (SPI, I²C). The 16-channel 10-bit ADC provides analog acquisition without an external converter. On-chip peripherals also include brown-out detect/reset, DMA, I²S, POR, PWM, and WDT. The 67 I/O lines give enough headroom for a parallel display or memory bus alongside GPIO. ## Package, power, and temperature grade Housed in a 108-LFBGA package with a supplier device package designation of 108-BGA (10x10). The 10x10 mm body with a 0.80 mm ball pitch is a standard footprint for this density — four-layer board with via-in-pad is typical for fan-out.","metaTitle":"Texas Instruments LM3S2U93-IBZ80-A2 Cortex-M3 MCU, 80MHz","metaDescription":"Texas Instruments LM3S2U93-IBZ80-A2 Stellaris ARM Cortex-M3 MCU, 80MHz, 384KB Flash, 96KB RAM, 108-BGA.
