ETC CY7C136

CY7C132/CY7C136
CY7C142/CY7C146
2K x 8 Dual-Port Static RAM
Features
Functional Description
• True Dual-Ported memory cells which allow simultaneous reads of the same memory location
• 2K 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
• Master CY7C132/CY7C136 easily expands data bus
width to 16 or more bits using slave CY7C142/CY7C146
• BUSY output flag on CY7C132/CY7C136; BUSY input
on CY7C142/CY7C146
• INT flag for port-to-port communication (52-pin
PLCC/PQFP versions)
• Available in 48-pin DIP (CY7C132/142), 52-pin PLCC and
52-pin TQFP (CY7C136/146)
• Pin-compatible and functionally equivalent to
IDT7132/IDT7142
The CY7C132/CY7C136/CY7C142 and CY7C146 are
high-speed CMOS 2K by 8 dual-port static RAMs. Two ports
are provided to permit independent access to any location in
memory. The CY7C132/ CY7C136 can be utilized as either a
standalone 8-bit dual-port static RAM or as a MASTER
dual-port RAM in conjunction with the CY7C142/CY7C146
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 a unique location (7FF for the left port and 7FE for
the right port).
An automatic power-down feature is controlled independently
on each port by the chip enable (CE) pins.
The CY7C132/CY7C142 are available in 48-pin DIP. The
CY7C136/CY7C146 are available in 52-pin PLCC and PQFP.

Notes:
1. CY7C132/CY7C136 (Master): BUSY is open drain output and requires pull-up resistor.
CY7C142/CY7C146 (Slave): BUSY is input.
2. Open drain outputs; pull-up resistor required.

Notes:
10. 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.
11. AC test conditions use VOH = 1.6V and VOL = 1.4V.
12. At any given temperature and voltage condition for any given device, tHZCE is less than tLZCE and tHZOE is less than tLZOE.
13. tLZCE, tLZWE, tHZOE, tLZOE, tHZCE, and tHZWE are tested with CL = 5pF as in (b) of AC Test Loads. Transition is measured ±500 mV from steady-state voltage.
14. The internal write time of the memory is defined by the overlap of CE 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.

15. These parameters are measured from the input signal changing, until the output pin goes to a high-impedance state.
16. CY7C142/CY7C146 only.
17. 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 toggled.
CE for Port B is toggled.
R/W for Port B is toggled during valid read.
18. 52-pin PLCC and PQFP versions only.

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 a high-impedance state.
