CG5982AF 2K x 8 Automotive Dual-port Static RAM www.DataSheet4U.com CG5982AF 2K x 8 Automotive Dual-port Static RAM Features True dual-ported memory cells that allow simultaneous reads of the same memory location Automotive temperature operation: –40°C to +115°C 2K x 8 organization High-speed access: 55 ns Low operating power: ICC = 120 mA (max.) Fully asynchronous operation Automatic power-down Master CG5982AF easily expands data bus width to 16 or more bits using slave BUSY output flag INT flag for port-to-port communication Functional Description The CG5982AF are high-speed CMOS 2K x 8 dual-port static RAMs. Two ports are provided to permit independent access to any location in memory. The CG5982AF can be utilized as either a standalone 8-bit dual-port static RAM or as a MASTER dual-port RAM in conjunction with the CG5982AF 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). BUSY flags are provided on each port. In addition, an interrupt flag (INT) is provided on each port of the 52-pin PLCC version. BUSY signals that the port is trying to access the same location currently being accessed by the other port. On the PLCC version, INT is an interrupt flag indicating that data has been placed in ...
