CY62187EV30 MoBL® 64-Mbit (4 M × 16) Static RAM 64-Mbit (4 M × 16) Static RAM Features Functional Description ■ Very high speed ❐ 55 ns ■ Wide voltage range ❐ 2.2 V to 3.7 V ■ Ultra low standby power ❐ Typical standby current: 8 μA ❐ Maximum standby current: 48 μA ■ Ultra low active power ❐ Typical active current: 7.5 mA at f = 1 MHz ■ Easy memory expansion with CE1, CE2, and OE features ■ Automatic power down when deselected The CY62187EV30 is a high performance CMOS static RAM organized as 4 M words by 16-bits. This device features advanced circuit design to provide ultra low active current. It 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 by 99 percent when addresses are not toggling. The device can also be put into standby mode when deselected (CE1 HIGH or CE2 LOW or both BHE and BLE are HIGH). The input and output pins (I/O0 through I/O15) are placed in a high impedance state when: deselected (CE1HIGH or CE2 LOW), outputs are disabled (OE HIGH), both Byte High Enable and Byte Low Enable are disabled (BHE, BLE HIGH), or during a write operation (CE1 LOW, CE2 HIGH and WE LOW). ■ CMOS for optimum speed and power ■ Available in Pb-free 48-ball FBGA package To write to the device, take Chip Enables (CE1 LOW and CE2 HIGH) and Write Enable (WE) input 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 A21). 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 A21). To read from the device, take Chip Enables (CE1 LOW and CE2 HIGH) 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 appear on I/O0 to I/O7. If Byte High Enable (BHE) is LOW, then data from memory appears on I/O8 to I/O15. See the Truth Table on page 9 for a complete description of read and write modes.

At any 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. 16. tHZOE, tHZCE, tHZBE, and tHZWE transitions are measured when the outputs enter a high impedence state. 17. The internal Write time of the memory is defined by the overlap of WE, CE1 = VIL, BHE and/or BLE = 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.
