Functional Description
The CY62148EV30 is a high performance CMOS static RAM
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. Placing the device into standby mode reduces
power consumption by more than 99 percent when deselected
(CE HIGH). The eight input and 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).
To write to the device, take 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).
To read from the device, take 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 appear on the I/O pins.

13. Typical values are included for reference only and are not guaranteed or tested. Typical values are measured at VCC = VCC(typ), TA = 25 °C.
14. Chip Enable (CE) must be HIGH at CMOS level to meet the ISB1 / ISB2 / ICCDR spec. Other inputs can be left floating.
15. Tested initially and after any design or process changes that may affect these parameters.
16. Full device AC operation requires linear VCC ramp from VDR to VCC(min) > 100 s or stable at VCC(min) > 100 s.

Notes
17. In an earlier revision of this device, under a specific application condition, READ and WRITE operations were limited to switching of the chip enable signal as described
in the Application Note AN66311. However, the issue has been fixed and in production now, and hence, this Application Note is no longer applicable. It is available
for download on our website as it contains information on the date code of the parts, beyond which the fix has been in production.
18. Test Conditions for all parameters other than tri-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 Figure 1 on page 5.
19. SOIC package is available only in 55 ns speed bin.
20. 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.
21. tHZOE, tHZCE, and tHZWE transitions are measured when the output enter a high impedance state.
22. 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.
23. 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.
