CY7C1011DV33

CY7C1011DV33 2-Mbit (128K x 16)Static RAM Features • Pin-and function-compatible with CY7C1011CV33 • High speed — tAA = 10 ns • Low active power — ICC = 90 mA @ 10 ns (Industrial) • Low CMOS standby power • • • • • — ISB2 = 10 mA Data Retention at 2.0 V Automatic power-down when deselected Independent control of upper and lower bits Easy memory expansion with CE and OE features Available in Lead-Free 44-pin TSOP II, and 48-ball VFBGA Functional Description The CY7C1011DV33 is a high-performance CMOS Static RAM organized as 128K words by 16 bits. 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 through I/O7), is written into the location specified on the address pins (A0 through A16). 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 A16). 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 to 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 through 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 CY7C1011DV33 is available in standard Lead-Free 44-pin TSOP II with center power and ground pinout, as well as 48-ball fine-pitch ball grid array (VFBGA) packages .

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 is performed. 7. tHZOE, tHZCE, tHZBE and tHZWE are specified with a load capacitance of 5 pF as in part (d) of AC Test Loads. Transition is measured when the outputs enter a high impedance state. 8. At any given temperature and voltage condition, tHZCE is less than tLZCE, tHZOE is less than tLZOE, tHZBE is less than tLZBE, and tHZWE is less than tLZWE for any given device.

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. 4 (WE controlled, OE LOW) is the sum of tHZWE and tSD. 11. Device is continuously selected. OE, CE, BHE and/or BHE = VIL. 12.
