The 48-TLLGA package (5.5x5.5 mm) with exposed pad is sized for space-constrained or low-profile board designs where a QFP would take up more real estate. 36 general-purpose I/O lines are available, along with I²C, SPI, and UART/USART serial interfaces. On-chip peripherals include brown-out detect, DMA, POR, PWM, and a watchdog timer. An internal oscillator keeps the BOM count low — no external crystal needed for the core clock. The ADC block provides eight 12-bit channels for analog sensor inputs. The 48-TLLGA (5.5x5.5 mm) is a land-grid array with an exposed thermal pad — the reflow profile must match the LGA solder-paste stencil, and post-reflow inspection requires X-ray or side-scope verification of the hidden joints.
