Functional Description[1]
The CY62148DV30 is a high-performance CMOS static RAMs
organized as 512K 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 by 99% when addresses are not
toggling. The device can be put into standby mode reducing
power consumption by more than 99% when deselected (CE
HIGH).
Writing to the device is accomplished by taking Chip Enable
(CE) and Write Enable (WE) inputs LOW. Data on the eight I/O
pins (I/O0 through I/O7) is then written into the location
specified on the address pins (A0 through A18).
Reading from the device is accomplished by taking Chip
Enable (CE) 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 will appear
on the I/O pins.
The eight input/output pins (I/O0 through I/O7) are placed in a
high-impedance state when the device is deselected (CE
HIGH), the outputs are disabled (OE HIGH), or during a write
operation (CE LOW and WE LOW).

5. VIH(max)=VCC+0.75V for pulse durations less than 20 ns.
6. Full Device AC operation requires linear VCC ramp from 0 to VCC(min) and VCC must be stable at VCC(min) for >= 500 µs.
7. Typical values are included for reference only and are not guaranteed or tested. Typical values are measured at VCC = VCC(typ.), TA = 25°C.

Notes:
10. Test Conditions for all parameters other than three-state parameters assume signal transition time of 3 ns or less (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 the “AC Test Loads and Waveforms” section.
11. 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.
12. tHZOE, tHZCE, and tHZWE transitions are measured when the output enter a high impedance state.
13. 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 set-up and hold timing should be referenced to the edge of the signal that terminates the write.
14. Device is continuously selected. OE, CE = VIL.
15. WE is HIGH for read cycle.
