Functional Description[1]
The CY62138EV30 is a high-performance CMOS static RAM organized as 256K words by 8 bits. This device features advanced circuit design to provide ultra-low active current. This is ideal for providing More Battery LifeTM (MoBL(R)) in portable applications such as cellular telephones. The device also has an automatic power-down feature that significantly reduces power consumption. The device can be put into standby mode reducing power consumption 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).

Notes: 9. 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. 10. 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. 11. tHZOE, tHZCE, and tHZWE transitions are measured when the output enter a high-impedance state. 12. 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. 13. Device is continuously selected. OE, CE = VIL. 14. WE is HIGH for read cycle.
