1-Mbit (64 K × 16) Static RAM
Features
Functional Description
■
High speed: 45 ns
The CY62126EV30 is a high performance CMOS static RAM
organized as 64K 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 when addresses are not toggling. Placing the
device in standby mode reduces power consumption by more
than 99 percent when deselected (CE HIGH). The input and
output pins (I/O0 through I/O15) are placed in a high impedance
state when the device is deselected (CE HIGH), the outputs are
disabled (OE HIGH), both Byte High Enable and Byte Low
Enable are disabled (BHE, BLE HIGH) or during a write
operation (CE LOW and WE LOW).

packages
To write to the device, take Chip Enable (CE) and Write Enable
(WE) inputs 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 A15). 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 A15).
To read from the device, take Chip Enable (CE) 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.

3. VIL(min) = –2.0 V for pulse durations less than 20 ns.
4. VIH(max) = VCC + 0.75 V for pulse durations less than 20 ns.
5. Full device AC operation assumes a 100 s ramp time from 0 to Vcc(min) and 200 s wait time after Vcc stabilization.
6. Typical values are included for reference only and are not guaranteed or tested. Typical values are measured at VCC = VCC(typ), TA = 25 °C.
7. Chip enable (CE) needs to be tied to CMOS levels to meet the ISB1 / ISB2 / ICCDR spec. Other inputs can be left floating.

Notes
13. Test conditions assume signal transition time of 3 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 and 30-pF load capacitance.
14. AC timing parameters are subject to byte enable signals (BHE or BLE) not switching when chip is disabled. See application note AN13842 for further clarification.
15. At any 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 device.
16. tHZOE, tHZCE, tHZBE, and tHZWE transitions are measured when the outputs enter a high impedance state.
17. The internal write time of the memory is defined by the overlap of WE, CE = VIL, BHE, BLE or both = VIL. 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 refer to the edge of signal that terminates write.
