CY62158EV30 MoBL® 8-Mbit (1024 K × 8) Static RAM 8-Mbit (1024 K × 8) Static RAM Features Functional Description ■ Very high speed: 45 ns ❐ Wide voltage range: 2.20 V–3.60 V ■ Pin compatible with CY62158DV30 ■ Ultra low standby power ❐ Typical standby current: 2 A ❐ Maximum standby current: 8 A ■ Ultra low active power ❐ Typical active current: 1.8 mA at f = 1 MHz ■ Easy memory expansion with CE1, CE2, and OE features ■ Automatic power down when deselected ■ CMOS for optimum speed/power ■ Offered in Pb-free 48-ball VFBGA and 44-pin TSOP II packages The CY62158EV30 is a high performance CMOS static RAM organized as 1024K words by 8 bits. This device features advanced circuit design to provide ultra low active current. This is ideal for providing More Battery Life™ (MoBL) in portable applications such as cellular telephones. The device also has an automatic power down feature that significantly reduces power consumption. Placing the device into standby mode reduces power consumption significantly when deselected (CE1 HIGH or CE2 LOW). The eight input and output pins (I/O0 through I/O7) are placed in a high impedance state when the device is deselected (CE1 HIGH or CE2 LOW), the outputs are disabled (OE HIGH), or a write operation is in progress (CE1 LOW and CE2 HIGH and WE LOW). To write to the device, take Chip Enables (CE1 LOW and CE2 HIGH) and Write Enable (WE) input LOW. 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). To read from the device, take Chip Enables (CE1 LOW and CE2 HIGH) and OE LOW while forcing the WE HIGH. Under these conditions, the contents of the memory location specified by the address pins appear on the I/O pins. See Truth Table on page 10 for a complete description of read and write modes.

Test conditions for all parameters other than tri-state parameters assume signal transition time of 3 ns 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 AC Test Loads and Waveforms on page 5. 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 setup and hold timing should be referenced to the edge of the signal that terminates the write.
