Cypress CY62128ELL-45SXI 1-mbit (128k x 8) static ram Datasheet

MoBL® CY62128E
1-Mbit (128K x 8) Static RAM
Features
Functional Description
The CY62128E[1] is a high performance CMOS static RAM
organized as 128K 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 reduces power
consumption when addresses are not toggling. Placing the
device into standby mode reduces power consumption by more
than 99 percent when deselected (CE1 HIGH or CE2 LOW). The
eight input and output pins (IO0 through IO7) are placed in a high
impedance state when the device is deselected (CE1 HIGH or
CE2 LOW), the outputs are disabled (OE HIGH), or a write
operation is in progress (CE1 LOW and CE2 HIGH and WE LOW)
■

■
Voltage range: 4.5V to 5.5V
■
Pin compatible with CY62128B
■
Ultra low standby power
❐ Typical standby current: 1 μA
❐ Maximum standby current: 4 μA (Industrial)
■
Ultra low active power
❐ Typical active current: 1.3 mA at f = 1 MHz
■
Easy memory expansion with CE1, CE2, and OE features
■
Automatic power down when deselected
■
CMOS for optimum speed and power
■
Offered in standard Pb-free 32-pin STSOP, 32-pin SOIC, and
32-pin TSOP I packages
To write to the device, take Chip Enable (CE1 LOW and CE2
HIGH) and Write Enable (WE) inputs LOW. Data on the eight IO
pins (IO0 through IO7) is then written into the location specified
on the address pins (A0 through A16).
To read from the device, take Chip Enable (CE1 LOW and CE2
HIGH) and Output Enable (OE) LOW while forcing Write Enable
(WE) HIGH. Under these conditions, the contents of the memory
location specified by the address pins appear on the IO pins.

10. Full device AC operation requires linear VCC ramp from VDR to VCC(min) > 100 μs or stable at VCC(min) > 100 μs.
11. CE is the logical combination of CE1 and CE2. When CE1 is LOW and CE2 is HIGH, CE is LOW; when CE1 is HIGH or CE2 is LOW, CE is HIGH.

Notes
12. Test conditions for all parameters other than tri-state parameters assume signal transition time of 3ns (1V/ns) or less, timing reference levels of 1.5V, input pulse
levels of 0 to 3V, and output loading of the specified IOL/IOH as shown in the “” on page 4.
13. 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.
14. tHZOE, tHZCE, and tHZWE transitions are measured when the outputs enter a high impedance state.
15. The internal Write time of the memory is defined by the overlap of WE, CE = 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 be referenced to the edge of the signal that terminates the write.

16. The device is continuously selected. OE, CE1 = VIL, CE2 = VIH.
17. WE is HIGH for read cycle.
18. Address valid before or similar to CE1 transition LOW and CE2 transition HIGH.
19. Data IO is high impedance if OE = VIH.
20. If CE1 goes HIGH or CE2 goes LOW simultaneously with WE HIGH, the output remains in high impedance state.
21. During this period, the IOs are in output state and input signals must not be applied.
