MITSUBISHI <DIGITAL ASSP>
PIN CONFIGURATION (TOP VIEW)
DESCRIPTION
M66850/851/852/853 are very high-speed and clock synchronous
FIFO(First-In,First-Out) memories fabricated by high-speed CMOS
technology.
These FIFOs are applicable for a data buffer as networks and
communications.
The write operation is controlled by a write clock pin(WCLK) and
two write enable pins(WEN1,WEN2).
Data present at the data input pins(D0-D8) is written into the
Synchronous FIFO on every rising write clock edge when the
device is enabled for writing.
The read operation is controlled by a read clock pin(RCLK) and
two read enable pins(REN1,REN2).
Data is read from the Synchronous FIFO on every rising read clock
edge when the device is enabled for reading. An output enable
pin(OE) controls the states of the data output pins(Q0-Q8).
MITSUBISHI FIFOs have four flags (EF,FF,PAE,PAF). The empty
flag EF and the full flag FF are fixed flags. The almost empty flag
PAE and the almost full flag PAF are programmable flags. The
programmable flag offset is initiated by the load pin(LD).
