Functional Description
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.
Features
• True Dual-Ported memory cells which allow simultaneous reads of the same memory location
• 1K x 8 organization
• 0.65-micron CMOS for optimum speed/power
• High-speed access: 15 ns
• Low operating power: ICC = 110 mA (max.)
• Fully asynchronous operation
• Automatic power-down
• Master CY7C130/CY7C131 easily expands data bus width to 16 or more bits using slave CY7C140/CY7C141
• BUSY output flag on CY7C130/CY7C131; BUSY input on CY7C140/CY7C141
• INT flag for port-to-port communication
• Available in 48-pin DIP (CY7C130/140), 52-pin PLCC, 52-Pin TQFP.
• Pb-Free packages available
