toggling. Placing the device into standby mode reduces power
consumption by more than 99% when deselected (Chip
Enable 1 (CE1) HIGH or Chip Enable 2 (CE2) LOW). The input

impedance state when: the device is deselected (Chip Enable
1 (CE1) HIGH or Chip Enable 2 (CE2) LOW), outputs are
disabled (OE HIGH), or a write operation is in progress (Chip
Enable 1 (CE1) LOW and Chip Enable 2 (CE2) HIGH and WE
LOW).

Functional Description[1]
The CY62168EV30 is a high performance CMOS static RAM
organized as 2M words by 8 bits. This device features
advanced circuit design to provide an 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 90% when addresses are not
Write to the device by taking Chip Enable 1 (CE1) LOW and
Chip Enable 2 (CE2) HIGH and the Write Enable (WE) input
LOW. Data on the eight IO pins (IO0 through IO7) is then
written into the location specified on the address pins (A0
through A20).
Read from the device 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 IO pins.
The eight input and output pins (IO0 through IO7) are placed
in a high impedance state when the device is deselected (CE1
LOW and CE2 HIGH), the outputs are disabled (OE HIGH), or
a write operation is in progress (CE1 LOW and CE2 HIGH and
WE LOW). See the “Truth Table” on page 8 for a complete
description of read and write modes.

Notes
11. 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 4.
12. 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.
13. tHZOE, tHZCE, and tHZWE transitions are measured when the outputs enter a high impedance state.
14. 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.
