CY62167DV18 MoBL® 16-Mbit (1M x 16) Static RAM Features consumption by more than 99% when deselected (CE1 HIGH or CE2 LOW or both BHE and BLE are HIGH). The input and output pins (IO0 through IO15) are placed in a high impedance state when: • Deselected (CE1 HIGH or CE2 LOW) • Outputs are disabled (OE HIGH) • Both Byte High Enable (BHE) and Byte Low Enable (BLE) are disabled (BHE, BLE HIGH) • Write operation is active (CE1 LOW, CE2 HIGH and WE LOW) • Very high speed: 55 ns • Wide voltage range: 1.65V–1.95V • Ultra low active power — Typical active current: 1.5 mA @ f = 1 MHz • • • • • — Typical active current: 15 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 and power Available in Pb-free 48-ball VFBGA package Functional Description[1] The CY62167DV18 is a high performance CMOS static RAM organized as 1M 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 automatic power down feature that significantly reduces power consumption by 99% when addresses are not toggling. Placing the device into standby mode reduces power To write to the device, take Chip Enables (CE1 LOW and CE2 HIGH) and Write Enable (WE) input LOW. If BLE is LOW, then data from IO pins (IO0 through IO7) is written into the location specified on the address pins (A0 through A19). If BHE is LOW then data from IO pins (IO8 through IO15) is 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. If BLE is LOW, then data from the memory location specified by the address pins appear on IO0 to IO7. If BHE is LOW, then data from memory appears on IO8 to IO15. See the “Truth Table” on page 9 for a complete description of read and write modes.

Test conditions for all parameters other than tri-state parameters assume signal transition time of 1 ns/V, 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 4. 11. 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. 12. tHZOE, tHZCE, tHZBE, and tHZWE transitions are measured when the outputs enter a high impedance state. 13. The internal write time of the memory is defined by the overlap of WE, CE1 = VIL, BHE, BLE or both = 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.
