Most single-power-supply AMD Flash devices have part numbers that begin with "Am29," followed by one or two letters that indicate the technology used in the particular family of devices. An "F" indicates 5 V devices. The letters "LW' indicate "low voltage," and refer to devices that may operate as low as 2.7 V. The letters "DL" indicate dual-bank (read-while-write) and low voltage. Following the letters are three digits that indicate the density and organization of the Flash device. In general, Flash memories that only provide a byte wide (x8-only) organization have numbers less than 100. The Flash memories that support both byte and word modes have numbers greater than or equal t0 100. See Table l for examples.
