The CY7C130/CY7C131/CY7C140 and CY7C141 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/ CY7C131 can be utilized 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
multiprocessor 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 has been placed in a unique location (3FF for the left
port and 3FE for the right port). An automatic power-down
feature is controlled independently on each port by the chip
enable (CE) pins.
The CY7C130 and CY7C140 are available in 48-pin DIP. The
CY7C131 and CY7C141 are available in 52-pin PLCC, 52-pin
Pb-free PLCC, 52-pin PQFP and 52-pin Pb-free PQFP.
