Cypress CY7C109V33-15VC 128k x 8 static ram Datasheet

CY7C1009V33
CY7C109V33
128K x 8 Static RAM
Features
memory expansion is provided by an active LOW Chip Enable
(CE1), an active HIGH Chip Enable (CE2), an active LOW Output Enable (OE), and three-state drivers. Writing to the device
is accomplished by taking Chip Enable one (CE1) and Write
Enable (WE) inputs LOW and Chip Enable two (CE2) input
HIGH. Data on the eight I/O pins (I/O 0 through I/O 7) is then
written into the location specified on the address pins (A0
through A16).
• High speed
— tAA = 15, 20, 25ns
• VCC = 3.3V ± 10%
• Low active power
— 432 mW (max.)
— 288 mW (L version)
• Low CMOS standby power
— 18 mW (max.)

Automatic power-down when deselected
TTL-compatible inputs and outputs
Easy memory expansion with CE1, CE2, and OE options
Functional Description
The CY7C109V33/CY7C1009V33 is a high-performance
CMOS static RAM organized as 131,072 words by 8 bits. Easy
Reading from the device is accomplished by taking Chip Enable one (CE1) and Output Enable (OE) LOW while forcing
Write Enable (WE) and Chip Enable two (CE2) HIGH. Under
these conditions, the contents of the memory location specified by the address pins will appear on the I/O pins.
The eight input/output pins (I/O0 through I/O7) are placed in a
high-impedance state when the device is deselected (CE1
HIGH or CE 2 LOW), the outputs are disabled (OE HIGH), or
during a write operation (CE1 LOW, CE2 HIGH, and WE LOW).
The CY7C109V33 is available in standard 32-pin,
400-mil-wide SOJ package. The CY7C1009V33 is available in
a 32-pin, 300-mil-wide SOJ package. The CY7C1009V33 and
CY7C109V33 are functionally equivalent in all other respects.

Notes:
4. 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
I OL/IOH and 30-pF load capacitance.
5. t HZOE, tHZCE, and tHZWE are specified with a load capacitance of 5 pF as in part (b) of AC Test Loads. Transition is measured ±500 mV from steady-state voltage.
6. At any given temperature and voltage condition, tHZCE is less than tLZCE, tHZOE is less than tLZOE, and tHZWE is less than tLZWE for any given device.
7. The internal write time of the memory is defined by the overlap of CE1 LOW, CE2 HIGH, and WE LOW. CE1 and WE must be LOW and CE2 HIGH 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.
8. The minimum write cycle time for Write Cycle No. 3 (WE controlled, OE LOW) is the sum of tHZWE and tSD.
