CY62146DV30
4-Mbit (256K x 16) Static RAM
Features
* Very high speed: 45 ns * Wide voltage range: 2.20V-3.60V * Pin-compatible with CY62146CV30 * Ultra-low active power -- Typical active current: 1.5 mA @ f = 1 MHz -- Typical active current: 8 mA @ f = fmax * Ultra low standby power * Easy memory expansion with CE, and OE features * Automatic power-down when deselected * CMOS for optimum speed/power * Packages offered 48-ball BGA and 44-pin TSOPII * Also available in Lead-free packages an automatic power-down feature that significantly reduces power consumption. The device can also be put into standby mode reducing power consumption by more than 99% when deselected (CE HIGH). The input/output pins (I/O0 through I/O15) are placed in a high-impedance state when: deselected (CE HIGH), outputs are disabled (OE HIGH), both Byte High Enable and Byte Low Enable are disabled (BHE, BLE HIGH), or during a write operation (CE LOW and WE LOW). 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 A17). 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 A17). 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 CY62146DV30 is available in a 48-ball VFBGA, 44-pin TSOPII packages.

Notes: 12. Test conditions for all parameters other than three-state parameters assume signal transition time of 3 ns (1V/ns) or less, timing reference levels of VCC(typ)/2, input pulse levels of 0 to VCC(typ.), and output loading of the specified IOL/IOH as shown in the "AC Test Loads and Waveforms" section. 13. At any given temperature and voltage condition, tHZCE is less than tLZCE, tHZBE is less than tLZBE, tHZOE is less than tLZOE, and tHZWE is less than tLZWE for any given device. 14. tHZOE, tHZCE, tHZBE, and tHZWE transitions are measured when the outputs enter a high-impedence state. 15. The internal Write time of the memory is defined by the overlap of WE, CE = VIL, BHE and/or BLE = VIL. All signals must be ACTIVE to initiate a write and any of these signals can terminate a write by going INACTIVE. The data input set-up and hold timing should be referenced to the edge of the signal that terminates the write.
