2K x 8 Dual-Port Static RAM
Features
Functional Description
■
True dual-ported memory cells that enable simultaneous reads
of the same memory location
■
2K x 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 CY7C132, CY7C136, CY7C136A, CY7C142, and CY7C146
are high speed CMOS 2K x 8 dual-port static RAMs. Two ports
are provided to permit independent access to any location in
memory. The CY7C132, CY7C136, and CY7C136A can be used
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. They are used in
systems that require 16-bit or greater word widths. This is the
solution to applications that require shared or buffered data, such
as cache memory for DSP, bit-slice, or multiprocessor designs.
■
Automatic power-down
■
Master CY7C132/CY7C136/CY7C136A[1] easily expands data
bus width to 16 or more bits using slave CY7C142/CY7C146
■
BUSY output flag on CY7C132/CY7C136/CY7C136A;
BUSY input on CY7C142/CY7C146
■
INT flag for port to port communication (52-Pin PLCC/PQFP
versions)
■
CY7C136, CY7C136A, and CY7C146 available in 52-pin
PLCC and 52-pin PQFP packages
■
Pb-free packages available
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 is placed in an 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.

Notes
1. CY7C136 and CY7C136A are functionally identical.
2. CY7C132/CY7C136/CY7C136A (Master): BUSY is open drain output and requires pull up resistor. CY7C142/CY7C146 (Slave): BUSY is input.
3. Open drain outputs; pull up resistor required.

8. Test conditions assume signal transition times of 5 ns or less, timing reference levels of 1.5 V, input pulse levels of 0 to 3.0 V and output loading of the specified IOL/IOH,
and 30 pF load capacitance.
9. AC test conditions use VOH = 1.6 V and VOL = 1.4 V.
10. At any given temperature and voltage condition for any given device, tHZCE is less than tLZCE and tHZOE is less than tLZOE.
11. tLZCE, tLZWE, tHZOE, tLZOE, tHZCE, and tHZWE are tested with CL = 5pF as in (b) of AC Test Loads and Waveforms. Transition is measured ± 500 mV from steady state
voltage.

Notes
12. 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 must be referenced to the rising edge of the signal that terminates the write.
13. These parameters are measured from the input signal changing, until the output pin goes to a high impedance state.
14. CY7C142/CY7C146 only.
15. 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.
16. 52-pin PLCC and PQFP versions only.
