1K x 8 Dual-Port Static Ram
Features
Functional Description
• True Dual-Ported memory cells which allow simultaneous reads of the same memory location
• 1K x 8 organization
• 0.65-micron CMOS for optimum speed/power
• High-speed access: 15 ns
• Low operating power: ICC = 90 mA (max.)
• Fully asynchronous operation
• Automatic power-down
• 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 and
52-pin TQFP
• Pin-compatible and functionally equivalent to
IDT7130/IDT7140
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

to be placed on the bus for the required tSD.
