CY7C1041CV33
4-Mbit (256K x 16) Static RAM
Functional Description[1]
Features
• Pin equivalent to CY7C1041BV33
The CY7C1041CV33 is a high-performance CMOS Static
RAM organized as 262,144 words by 16 bits.
• Temperature Ranges
Writing to the device is accomplished by taking Chip Enable
(CE) and Write Enable (WE) inputs LOW. If Byte LOW Enable
(BLE) is LOW, then data from I/O pins (I/O0–I/O7), is written
into the location specified on the address pins (A0–A17). If Byte
HIGH Enable (BHE) is LOW, then data from I/O pins
(I/O8–I/O15) is written into the location specified on the
address pins (A0–A17).
— Commercial: 0°C to 70°C
— Industrial: –40°C to 85°C
— Automotive: –40°C to 125°C
• High speed
— tAA = 10 ns
• Low active power
— 324 mW (max.)
• 2.0V data retention
• Automatic power-down when deselected
• TTL-compatible inputs and outputs
• Easy memory expansion with CE and OE features
Reading from the device is accomplished by taking Chip
Enable (CE) and Output Enable (OE) LOW while forcing 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 – I/O7. If Byte HIGH Enable (BHE) is
LOW, then data from memory will appear on I/O8 to I/O15. See
the truth table at the back of this data sheet for a complete
description of Read and Write modes.
The input/output pins (I/O0–I/O15) are placed in a
high-impedance state when the device is deselected (CE
HIGH), the outputs are disabled (OE HIGH), the BHE and BLE
are disabled (BHE, BLE HIGH), or during a Write operation
(CE LOW, and WE LOW).
The CY7C1041CV33 is available in a standard 44-pin
400-mil-wide body width SOJ and 44-pin TSOP II package
with center power and ground (revolutionary) pinout, as well
as a 48-ball fine-pitch ball grid array (FBGA) package.

Notes:
5. 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.
6. 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.
7. tHZOE, tHZCE, and tHZWE are specified with a load capacitance of 5 pF as in part (d) of AC Test Loads. Transition is measured ±500 mV from steady-state voltage.
8. 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.
9. 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
either 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.
10. The minimum Write cycle time for Write Cycle No. 3 (WE controlled, OE LOW) is the sum of tHZWE and tSD.

Notes:
11. AC characteristics (except High-Z) for all 8-ns and 10-ns parts are tested using the load conditions shown in Figure (a). All other speeds are tested using the
Thevenin load shown in Figure (b). High-Z characteristics are tested for all speeds using the test load shown in Figure (d).
12. Device is continuously selected. OE, CE, BHE and/or BHE = VIL.
13. WE is HIGH for Read cycle.
14. Address valid prior to or coincident with CE transition LOW.
