The 512 KB on-chip Flash and 48 KB SRAM leave room for a moderate application after the HAL and RTOS footprint. ## Package and board-fit reality Housed in a 108-BGA (10x10 mm) package. The 0.65 mm ball pitch demands a 4-layer PCB for fan-out — two-layer boards won't break out the inner rows. Reflow soldering is required; hand-soldering a BGA of this density is not practical. The 67 I/O lines include an external bus interface (EBI/EMI), multiple serial ports (I²C, SPI, UART, IrDA, LIN, Microwire, SSI), and 8 channels of 12-bit ADC.","metaTitle":"LM3S1H11-IBZ80-A2 Texas Instruments MCU, 80MHz Cortex-M3","metaDescription":"Texas Instruments LM3S1H11-IBZ80-A2 Stellaris ARM Cortex-M3 MCU, 80 MHz, 512KB Flash, 48KB SRAM, 108-BGA.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"80MHz","Series":"Stellaris® ARM® Cortex®-M3S 1000","Package":"Tray","RAM Size":"48K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, POR, PWM, WDT","Connectivity":"EBI/EMI, I²C, IrDA, LINbus, Microwire, SPI, SSI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"67","Core Processor":"ARM® Cortex®-M3","Package / Case":"108-LFBGA","Product Status":"Obsolete","Data Converters":"A/D 8x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S1H11","Program Memory Size":"512KB (512K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"108-BGA (10x10)","Voltage - Supply (Vcc/Vdd)":"1.235V ~ 1.365V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/68920ccd04e046c9d0ddb9ddf41bb2dc.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to the LM3S1H11-IBZ80-A2?","answer":"The Stellaris family includes other Cortex-M3 parts with similar core and memory, but package and pinout differ — a board spin would be required.
