The Spansion MirrorBit® FL family SPI Flash memory device features a serial interface in densities ranging from 4 Mb to 128 Mb. The Mirrorbit FL SPI Flash transfers data one bit at a time instead of sending 8, 16, or 32 bits in parallel. This enables solutions to have fewer connections and pins per package for more simplified designs and lower costs. Other key features of this Spansion device include 50 MHz clock speed (104 MHz for 128 Mb), 1.5 ms/page programming time, low power operation with Deep Power Down mode (1.5 µA), and hardware/software write protect.
