CY62157EV18 MoBL® 8-Mbit (512K x 16) Static RAM 8-bit (512K x 16) Static RAM Features ■ Very high speed: 55 ns ■ Wide voltage range: 1.65 V–2.25 V ■ Pin compatible with CY62157DV18 and CY62157DV20 ■ 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 ■ Complementary metal oxide semiconductor (CMOS) for optimum speed and power ■ Available in Pb-free 48-ball very fine-pitch ball grid array (VFBGA) package automatic power down feature that significantly reduces power consumption 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 (CE1 HIGH or CE2 LOW) ■ Outputs are disabled (OE HIGH) ■ Both Byte High Enable and Byte Low Enable are disabled (BHE, BLE HIGH) or ■ Write operation is active (CE1 LOW, CE2 HIGH and WE LOW). Write to the device by taking 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 A18). 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 A18). Functional Description The CY62157EV18 is a high performance CMOS static RAM organized as 512K words by 16 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 Read from the device by taking 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 11 for a complete description of read and write modes.

Test conditions for all parameters other than tri-state parameters assume signal transition time of 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” on page 6. 15. AC timing parameters are subject to byte enable signals (BHE or BLE) not switching when chip is disabled. Please see application note AN13842 for further clarification. 16. 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. 17. tHZOE, tHZCE, tHZBE, and tHZWE transitions are measured when the output enters a high impedance state. 18. If both byte enables are toggled together, this value is 10 ns. 19. The internal write time of the memory is defined by the overlap of WE, CE = 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 must be referenced to the edge of the signal that terminates the write. Document #: 38-05490 Rev. *H Page 7 of 16 CY62157EV18 MoBL® Switching Waveforms Figure 1.
