CY7C130, CY7C130A CY7C131, CY7C131A CY7C140, CY7C141 1K x 8 Dual-Port Static RAM • True dual-ported memory cells, which allow simultaneous reads of the same memory location • 1K x 8 organization • micron CMOS for optimum speed and power • High speed access 15 ns • Low operating power ICC = 110 mA maximum • Fully asynchronous operation • Automatic power down • Master CY7C130/130A/CY7C131/131A easily expands data bus width to 16 or more bits using slave CY7C140/CY7C141 • BUSY output flag on CY7C130/130A/CY7C131/131A BUSY input on CY7C140/CY7C141 • INT flag for port-to-port communication • Available in 48-pin DIP CY7C130/130A/140 , 52-pin PLCC, 52-pin TQFP • Pb-free packages available Functional Description The CY7C130/130A/CY7C131/131A/CY7C140[1] 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 CY7C130/130A/ 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 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 is 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 CY7C130/130A 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.
