Functional Description
The CY7C130/130A/CY7C131/131A/CY7C140
are high speed CMOS 1K by 8 dual-port static RAMs. Two ports
are provided permitting independent access to any location in
memory. The CY7C130/130A/ CY7C131/131A can be used as
either a standalone 8-bit dual-port static RAM or as a master
dual-port RAM in conjunction with the CY7C140/CY7C141 slave
dual-port device in systems requiring 16-bit or greater word
widths. It is the solution to applications requiring shared or
buffered data, such as cache memory for DSP, bit-slice, or multi-
processor designs.
Each port has independent control pins; chip enable (CE), write
enable (R/W), and output enable (OE). Two flags are provided
on each port, BUSY and INT. BUSY signals that the port is trying
to access the same location currently being accessed by the
other port. INT is an interrupt flag indicating that data is placed
in a unique location (3FF for the left port and 3FE for the right
port). An automatic power down feature is controlled indepen-
dently on each port by the chip enable (CE) pins.
The CY7C130/130A and CY7C140 are available in 48-pin DIP.
The CY7C131/131A and CY7C141 are available in 52-pin
PLCC, 52-pin Pb-free PLCC, 52-pin PQFP, and 52-pin Pb-free
PQFP.
