M50FLW080ANB5TG

8兆位（ 13× 64K字节块+ 3 ×16× 4K字节扇区） ， 3V供应固件集线器/低引脚数闪存 8 Mbit 13 x 64KByte Blocks + 3 x 16 x 4KByte Sectors, 3V Supply Firmware Hub / Low Pin Count Flash Memory

Summary description

The M50FLW080 is a 8 Mbit 1M x8 non-volatile memory that can be read, erased and reprogrammed. These operations can be performed using a single low voltage 3.0 to 3.6V supply. For fast programming and fast erasing on production lines, an optional 12V power supply can be used to reduce the erasing and programming time.
