• Wide x16 organization offering easy expansion

• Low power consumption (50mA typical)

• Least/Most Significant Bit first read selected by asserting the

FL/DIR pin

• Four memory status flags: Empty, Full, Half-Full, and Almost-

Empty/Almost-Full

• Dual-Port zero fall-through architecture

• Available in 28-pin 300 mil plastic DIP and 28-pin SOIC

• Green parts available, see ordering information
