CY7C1061BV33
16-Mbit (1M x 16) Static RAM
Features
* High speed -- tAA = 10 ns * Low active power -- 990 mW (max.) * Operating voltages of 3.3 0.3V * 2.0V data retention * Automatic power-down when deselected * TTL-compatible inputs and outputs * Available in Pb-free and non Pb-free 54-pin TSOP II package 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). Reading from the device is accomplished by enabling the chip by taking CE LOW 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 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 CY7C1061BV33 is available in a 54-pin TSOP II package with center power and ground (revolutionary) pinout.

Notes: 5. Valid SRAM operation does not occur until the power supplies have reached the minimum operating VDD (3.0V). As soon as 1ms (Tpower) after reaching the minimum operating VDD, normal SRAM operation can begin including reduction in VDD to the data retention (VCCDR, 2.0V) voltage. 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 specified transmission line loads. Test conditions for the Read cycle use output loading shown in part a) of the AC test loads, unless specified otherwise. 7. This part has a voltage regulator which steps down the voltage from 3V to 2V internally. tpower time has to 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. 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 CE LOW 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 set-up 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. 3 (WE controlled, OE LOW) is the sum of tHZWE and tSD.
