CY62168DV30 MoBL® 16-Mbit (2M x 8) MoBL® Static RAM Features reduces power consumption. The device can be put into standby mode reducing power consumption by 90% when addresses are not toggling. The device can be put into standby mode reducing power consumption by more than 99% when deselected Chip Enable 1 (CE1) HIGH or Chip Enable 2 (CE2) LOW. The input/output pins (I/O0 through I/O7) are placed in a high-impedance state when: deselected Chip Enable 1 (CE1) HIGH or Chip Enable 2 (CE2) LOW, outputs are disabled (OE HIGH), or during a write operation (Chip Enable 1 (CE1) LOW and Chip Enable 2 (CE2) HIGH and WE LOW). • Very high speed — 55 ns • Wide voltage range — 2.2V – 3.6V • Ultra-low active power — Typical active current: 2 mA @ f = 1 MHz — Typical active current: 15 mA @ f = fMax (55 ns Speed) • Ultra-low standby power • Easy memory expansion with CE1, CE2 and OE features • Automatic power-down when deselected • CMOS for optimum speed/power • Available in Pb-free and non Pb-free 48-ball VFBGA package Functional Description[1] The CY62168DV30 is a high-performance CMOS static RAMs organized as 2048Kbit 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 Writing to the device is accomplished by taking Chip Enable 1 (CE1) LOW and Chip Enable 2 (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 A20). 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.

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. 11. 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. 12. tHZOE, tHZCE, 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, 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.
