Functional Description
■
High speed
❐ tAA = 10 ns
The CY7C1061AV33 is a high performance CMOS Static RAM
organized as 1,048,576 words by 16 bits.
■
Low active power
❐ 990 mW (max)
■
Operating voltages of 3.3 ± 0.3 V
■
2.0 V data retention
■
Automatic power down when deselected
■
TTL compatible inputs and outputs
To write to the device, enable the chip (CE1 LOW and CE2 HIGH)
while forcing the Write Enable (WE) input LOW. If Byte Low
Enable (BLE) is LOW, then data from I/O pins (I/O0 through I/O7),
is written into the location specified on the address pins (A0
through A19). If Byte High Enable (BHE) is LOW, then data from
I/O pins (I/O8 through I/O15) is written into the location specified
on the address pins (A0 through A19).
■
Easy memory expansion with CE1 and CE2 features
■
Available in Pb-free and non Pb-free 54-pin TSOP II package
and non Pb-free 60-ball fine-pitch ball grid array (FBGA)
package
To read from the device, enable the chip by taking CE1 LOW and
CE2 HIGH while forcing the Output Enable (OE) LOW and the
Write Enable (WE) HIGH. If Byte Low Enable (BLE) is LOW, then
data from the memory location specified by the address pins will
appear on I/O0 to I/O7. If Byte High Enable (BHE) is LOW, then
data from memory will appear on I/O8 to I/O15. See Truth Table
on page 8 for a complete description of Read and Write modes.
The input/output pins (I/O0 through I/O15) are placed in a
high-impedance state when the device is deselected (CE1
HIGH/CE2 LOW), the outputs are disabled (OE HIGH), the BHE
and BLE are disabled (BHE, BLE HIGH), or a Write operation is
in progress (CE1 LOW, CE2 HIGH, and WE LOW).

4. Tested initially and after any design or process changes that may affect these parameters.
5. Valid SRAM operation does not occur until the power supplies have reached the minimum operating VDD (3.0 V). As soon as 1 ms (Tpower) after reaching the
minimum operating VDD, normal SRAM operation can begin including reduction in VDD to the data retention (VCCDR, 2.0 V) voltage.

Notes
6. Test conditions assume signal transition time of 3 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 specified transmission line loads. Test conditions for the Read cycle use output loading shown in (a) of the AC Test Loads and Waveforms [5] on page 4, unless
specified otherwise.
7. This part has a voltage regulator that steps down the voltage from 3 V to 2 V internally. tpower time must be provided initially before a Read/Write operation is started.
8. tHZOE, tHZCE, tHZWE, tHZBE and tLZOE, tLZCE, t\LZWE, tLZBE are specified with a load capacitance of 5 pF as in (b) of AC Test Loads and Waveforms [5] on page 4.
Transition is measured 200 mV from steady-state voltage.
9. These parameters are guaranteed by design and are not tested.
10. The internal Write time of the memory is defined by the overlap of CE1 LOW (CE2 HIGH) and WE LOW. Chip enables must be active and WE and byte enables must
be LOW to initiate a Write, and the transition of any of these signals can terminate the Write. The input data setup and hold timing should be referenced to the leading
edge of the signal that terminates the Write.
11. The minimum Write cycle time for Write Cycle No. 2 (WE controlled, OE LOW) is the sum of tHZWE and tSD.
