The 256-byte extra row is typically used for calibration constants or unique device identifiers. The Flash is field-reprogrammable, so firmware can be patched in-system via UART or SPI. ## Package — 113-VFBGA Microstar Junior The 113-ball VFBGA measures 7x7 mm. The BGA footprint requires solder-paste stencil design and X-ray inspection for void detection.","metaTitle":"TI MSP430F478IZQW 16-bit MCU, 8MHz, 48KB Flash, 113-BGA","metaDescription":"MSP430F478IZQW from Texas Instruments, MSP430x4xx 16-bit MCU with 8MHz core, 48KB Flash, 2Kx8 RAM, 5x16b ADC, 1x12b DAC, -40 to 85°C, 113-VFBGA.
