CY7C107D
CY7C1007D
1-Mbit (1M x 1) Static RAM
Features
Functional Description [1]
■
Pin- and function-compatible with CY7C107B/CY7C1007B
■
High speed
The CY7C107D and CY7C1007D are high-performance CMOS
static RAMs organized as 1,048,576 words by 1 bit. Easy
memory expansion is provided by an active LOW Chip Enable
(CE) and tri-state drivers. These devices have an automatic
power-down feature that reduces power consumption by more
than 65% when deselected. The output pin (DOUT) is placed in a
high-impedance state when:
— tAA = 10 ns
■
Low active power
— ICC = 80 mA @ 10 ns
■
Low complementary metal oxide semiconductor (CMOS)
standby power
— ISB2 = 3 mA
■
Deselected (CE HIGH)
■
When the write operation is active (CE and WE LOW)
Write to the device by taking Chip Enable (CE) and Write Enable
(WE) inputs LOW. Data on the input pin (DIN) is written into the
memory location specified on the address pins (A0 through A19).
■
2.0 V data retention
■
Automatic power-down when deselected
■
CMOS for optimum speed/power
■
Transistor transistor logic (TTL) compatible inputs and outputs
■
CY7C107D available in Pb-free 28-pin 400-Mil wide Molded
SOJ package. CY7C1007D available in Pb-free 28-pin 300-Mil
wide Molded SOJ package
Read from the device by taking Chip Enable (CE) LOW while
while forcing Write Enable (WE) HIGH. Under these conditions,
the contents of the memory location specified by the address
pins appears on the data output (DOUT) pin.

Notes
6. Test conditions assume signal transition time of 3 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.
7. tPOWER gives the minimum amount of time that the power supply should be at typical VCC values until the first memory access can be performed.
8. At any given temperature and voltage condition, tHZCE is less than tLZCE and tHZWE is less than tLZWE for any given device.
9. tHZCE and tHZWE are specified with a load capacitance of 5 pF as in part (c) of “AC Test Loads and Waveforms [5]” on page 5. Transition is measured when the outputs enter a
high impedance state.
10. This parameter is guaranteed by design and is not tested.
11. The internal write time of the memory is defined by the overlap of CE LOW and WE LOW. CE and WE must be LOW to initiate a write, and the transition of any of these
signals can terminate the write. The input data set-up and hold timing should be referenced to the leading edge of the signal that terminates the write.
