CYPRESS CY7C131

CY7C130/CY7C131
CY7C140/CY7C141
1K x 8 Dual-Port Static RAM
Features
Functional Description
• True Dual-Ported memory cells which allow simultaneous reads of the same memory location
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.
• 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
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.
• 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
The CY7C130 and CY7C140 are available in 48-pin DIP. The
CY7C131 and CY7C141 are available in 52-pin PLCC, 52-pin
Pb-free PLCC, 52-pin PQFP and 52-pin Pb-free PQFP.

Note:
1. CY7C130/CY7C131 (Master): BUSY is open drain output and requires pull-up resistor
CY7C140/CY7C141 (Slave): BUSY is input.
2. Open drain outputs: pull-up resistor required.

Shaded areas contain preliminary information.
Note:
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.

Note:
16. These parameters are measured from the input signal changing, until the output pin goes to a high-impedance state.
17. CY7C140/CY7C141 only.
18. A write operation on Port A, where Port A has priority, leaves the data on Port B’s outputs undisturbed until one access time after one of the following:
BUSY on Port B goes HIGH.
Port B’s address is toggled.
CE for Port B is toggled.
R/W for Port B is toggled during valid read.

Notes:
22. 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.
23. If the CE LOW transition occurs simultaneously with or after the R/W LOW transition, the outputs remain in the high-impedance state.
