ECC requirements: The GD5F1GM7UEYIGR is a SPI NAND Flash, which differs from NOR Flash — the MCU or host must support hardware ECC (typically 1-bit/512B or 4-bit/512B error correction). If the host does not support ECC, the GD5F1GM7UEYIGR should not be used, and SPI NOR Flash should be considered instead
Bad block management: The GD5F1GM7UEYIGR may have factory bad blocks — software must implement bad block management and wear leveling
Power decoupling: Place a 0.1µF ceramic capacitor near the VCC pin of the GD5F1GM7UEYIGR for stable power
Pull-up resistors: Add 10kΩ pull-up resistors on CS, SCLK, and MOSI lines of the GD5F1GM7UEYIGR
PCB layout: The GD5F1GM7UEYIGR WSON-8-EP (6×8mm) has an exposed pad (EP) — connect the EP to ground for improved thermal and electrical performance
