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. 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 and PQFP.

Notes: 11. Test conditions assume signal transition times of 5 ns or less, timing reference levels of 1.5V, input pulse levels of 0 to 3.0V and output loading of the specified IOL/IOH, and 30-pF load capacitance. 12. AC Test Conditions use VOH = 1.6V and VOL = 1.4V. 13. At any given temperature and voltage condition for any given device, tHZCE is less than tLZCE and tHZOE is less than tLZOE. 14. tLZCE, tLZWE, tHZOE, tLZOE, tHZCE and tHZWE are tested with CL = 5pF as in part (b) of AC Test Loads. Transition is measured ±500 mV from steady state voltage. 15. The internal write time of the memory is defined by the overlap of CS LOW and R/W LOW. Both signals must be low to initiate a write and either signal can terminate a write by going high. The data input set-up and hold timing should be referenced to the rising edge of the signal that terminates the write
