CY62158DV30 MoBL
8-Mbit (1024K x 8) MoBL Static RAM
Features
* Very high speed: 45 ns, 55 ns and 70 ns -- Wide voltage range: 2.20V - 3.60V * Ultra-low active power -- Typical active current:1.5 mA @ f = 1 MHz -- Typical active current: 12 mA @ f = fmax * Ultra-low standby power * Easy memory expansion with CE1, CE2, and OE features * Automatic power-down when deselected * CMOS for optimum speed/power * Packages offered in a 48-ball BGA, 48-pin TSOPI, and 44-pin TSOPII This is ideal for providing More Battery LifeTM (MoBL) in portable applications such as cellular telephones. The device also has an automatic power-down feature that significantly reduces power consumption. The device can be put into standby mode reducing power consumption by 85% when deselected (CE1 HIGH or CE2 LOW). Writing to the device is accomplished by taking Chip Enable 1 (CE1) and Write Enable (WE) inputs LOW and Chip Enable 2 (CE2) HIGH. Data on the eight I/O pins (I/O0 through I/O7) is then written into the location specified on the address pins (A0 through A19). Reading from the device is accomplished by taking Chip Enable 1 (CE1) and Output Enable (OE) LOW and Chip Enable 2 (CE2) HIGH while forcing Write Enable (WE) 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 LOW and CE2 HIGH), the outputs are disabled (OE HIGH), or during a write operation (CE1 LOW and CE2 HIGH and WE LOW). See the truth table for a complete description of read and write modes.

Notes: 2. NC pins are not internally connected to the die. 3. DNU pins have to be left floating. 4. The BYTE pin in the TSOPI package has to be tied LOW to use the device as 1M x 8 SRAM. The 48-TSOPI package can also be used as a 512K x 16 SRAM by tying the BYTE signal HIGH. For 512K x 16 functionality, please refer to the CY62157DV30 data sheet.

Notes: 13. Test conditions for all parameters other than tri-state parameters assume signal transition time of 3ns or less (1V/ns), 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. 14. 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. 15. tHZOE, tHZCE, and tHZWE transitions are measured when the outputs enter a high impedance state. 16. The internal write time of the memory is defined by the overlap of WE, CE1 = VIL, and CE2 = VIH. 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.
