CY7C130, CY7C130A CY7C131, CY7C131A 1 K × 8 Dual-Port Static RAM 1 K × 8 Dual-Port Static RAM Features Functional Description ■ True dual-ported memory cells, which allow simultaneous reads of the same memory location ■ 1 K × 8 organization ■ 0.65 micron CMOS for optimum speed and power ■ High speed access: 15 ns ■ Low operating power: ICC = 110 mA (maximum) ■ Fully asynchronous operation The CY7C130/130A/CY7C131/131A/CY7C140[1] and CY7C141 are high speed CMOS 1 K 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. ■ 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 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.

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 setup and hold timing should be referenced to the rising edge of the signal that terminates the write. 37. If OE is LOW during a R/W controlled write cycle, the write pulse width must be the larger of tPWE or tHZWE + tSD to allow the data I/O pins to enter high impedance and for data to be placed on the bus for the required tSD. 38. These parameters are measured from the input signal changing, until the output pin goes to a high-impedance state. 39. If the CE LOW transition occurs simultaneously with or after the R/W LOW transition, the outputs remain in the high impedance state.
