CYPRESS CY62126EV30LL

MoBL®,CY62126EV30
1-Mbit (64K x 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[1]. 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 (IO0 through IO15) are placed in a high impedance
state when:
■
Temperature ranges
❐ Industrial: –40°C to +85°C
❐ Automotive: –40°C to +125°C
■
Wide voltage range: 2.2V to 3.6V
■
Pin compatible with CY62126DV30
■
Ultra low standby power
❐ Typical standby current: 1 μA
❐ Maximum standby current: 4 μA
■
Ultra low active power
❐ Typical active current: 1.3 mA at f = 1 MHz
■
Easy memory expansion with CE and OE features
■
Automatic power down when deselected
■
CMOS for optimum speed and power
■
Offered in Pb-free 48-ball VFBGA and 44-pin TSOP II
packages
■
Deselected (CE HIGH)
■
Outputs are disabled (OE HIGH)
■
Both Byte High Enable and Byte Low Enable are disabled
(BHE, BLE HIGH)
■
Write operation is active (CE LOW and WE LOW)
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 IO pins (IO0 through IO7) is written into the location
specified on the address pins (A0 through A15). If Byte High
Enable (BHE) is LOW, then data from IO pins (IO8 through IO15)
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 IO0 to IO7. If
Byte High Enable (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.

5. VIH(max) = VCC+0.75V for pulse durations less than 20 ns.
6. Full device AC operation assumes a 100 μs ramp time from 0 to Vcc(min) and 200 μs wait time after Vcc stabilization.
7. Only chip enable (CE) and byte enables (BHE and BLE) need to be tied to CMOS levels to meet the ISB2 / ICCDR spec. Other inputs can be left floating.

Notes
10. 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.
11. 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.
12. 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.
13. tHZOE, tHZCE, tHZBE, 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, 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.
