CY7C133-55JI

The CY7C133-55JI is one of the CY7C133 series.The CY7C133-55JI is high-speed CMOS 2K by 16  dual-port static RAMs. Two ports are provided permitting independent access to any location in memory. The CY7C133-55JI can be utilized as either a stand-alone 16-bit dual-port static RAM or as a master dual-port RAM in conjunction with the CY7C143 slave dual-port device in systems requiring 32-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 of the CY7C133-55JI are:(1)True dual-ported memory cells which allow   simultaneous reads of the same memory location; (2)2K x 16 organization; (3)0.65-micron CMOS for optimum speed/power; (4)High-speed access: 25/35/55 ns; (5)Low operating power: ICC = 150 mA (typ.); (6) Fully asynchronous operation; (7)Master CY7C133 expands data bus width to 32 bits or more using slave CY7C143; (8)BUSY output flag on CY7C133; BUSY input flag on CY7C143; (9)Available in 68-pin PLCC.

The absolute maximum ratings of the CY7C133-55JI can be summarized as:(1)Storage Temperature:?65°C to +150°C; (2)Ambient Temperature with Power Applied:-55°C to +125°C; (3)Supply Voltage to Ground Potential (Pin 48 to Pin 24):-0.5V to +7.0V; (4)DC Voltage Applied to Outputs in High-Z State:-0.5V to +7.0V.If you want to know more information such as the electrical characteristics about CY7C133-55JI, please download the datasheet in www.seekic.com or www.chinaicmart.com.
