Functional Description
The CY62167EV18 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
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
A19). 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 A19).
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 appears
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.

Notes
16. In an earlier revision of this device, under a specific application condition, READ and WRITE operations were limited to switching of the byte enable and/or chip enable
signals as described in the Application Notes AN13842 and AN66311. However, the issue has been fixed and in production now, and hence, these Application Notes
are no longer applicable. They are available for download on our website as they contain information on the date code of the parts, beyond which the fix has been in
production.
17. Test conditions for all parameters other than tri-state parameters are based on signal transition time of 1 V/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 Figure 2 on page 5.
18. 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.
19. tHZOE, tHZCE, tHZBE, and tHZWE transitions are measured when the output enters a high impedance state.
20. The internal memory write time 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 must be referenced to the edge of the signal that terminates the write.
21. The minimum write cycle pulse width for Write Cycle No. 3 (WE controlled, OE LOW) should be equal to the sum of tSD and tHZWE.

25. The internal memory write time 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 must be referenced to the edge of the signal that terminates the write.
26. Data I/O is high impedance if OE = VIH.
27. If CE1 goes HIGH and CE2 goes LOW simultaneously with WE = VIH, the output remains in a high impedance state.
