The CY62157EV30 is a high performance CMOS static RAM
organized as 512K words by 16 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. Place the device
into standby mode when deselected (CE1 HIGH or CE2 LOW or
both BHE and BLE are HIGH). The input or output pins (I/O0
through I/O15) are placed in a high impedance state when the
device is deselected (CE1HIGH or CE2 LOW), the outputs are
disabled (OE HIGH), Byte High Enable and Byte Low Enable are
disabled (BHE, BLE HIGH), or a write operation is active (CE1
LOW, CE2 HIGH and WE LOW).
To write to the device, take Chip Enable (CE1 LOW and CE2
HIGH) and Write Enable (WE) inputs LOW. If Byte Low Enable
(BLE) is LOW, then data from I/O pins (I/O0 through I/O7) is
written into the location specified on the address pins (A0 through
A18). If Byte High Enable (BHE) is LOW, then data from I/O pins
(I/O8 through I/O15) is written into the location specified on the
address pins (A0 through A18).
To read from the device, take Chip Enable (CE1 LOW and CE2
HIGH) 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 I/O0 to I/O7. If Byte High Enable (BHE) is LOW, then data from
memory appears on I/O8 to I/O15. See Truth Table on page 13
for a complete description of read and write modes.

Notes
1. NC pins are not connected on the die.
2. The 44-pin TSOP II package has only one chip enable (CE) pin.
3. The BYTE pin in the 48-pin TSOP I package must be tied HIGH to use the device as a 512 K × 16 SRAM. The 48-pin TSOP I package can also be used as a 1 M × 8
SRAM by tying the BYTE signal LOW. In the 1 M x 8 configuration, Pin 45 is A19, while BHE, BLE and I/O8 to I/O14 pins are not used.
4. 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
16. Test conditions for all parameters other than tri-state parameters 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 as shown in the Figure 4 on page 5.
17. In an earlier revision of this device, under a specific application condition, READ and WRITE operations were limited to switching of the byte enable and/or chip enable
signals as described in the Application Notes AN13842 and AN66311. However, the issue has been fixed and in production now, and hence, these Application Notes
are no longer applicable. They are available for download on our website as they contain information on the date code of the parts, beyond which the fix has been in
production.
18. 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.
19. tHZOE, tHZCE, tHZBE, and tHZWE transitions are measured when the outputs enter a high-impedance state.
20. If both byte enables are toggled together, this value is 10 ns.
21. The internal write time of the memory is defined by the overlap of WE, CE = VIL, BHE, BLE or both = VIL, and CE2 = VIH. 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.
22. The minimum write cycle time for Write Cycle No. 3 (WE Controlled, OE LOW) should be equal to the sum of tSD and tHZWE.

26. The internal write time of the memory is defined by the overlap of WE, CE = VIL, BHE, BLE or both = VIL, and CE2 = VIH. 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.
27. Data I/O is high impedance if OE = VIH.
28. If CE1 goes HIGH and CE2 goes LOW simultaneously with WE = VIH, the output remains in a high impedance state.
29. During this period, the I/Os are in output state. Do not apply input signals.

31. Data I/O is high impedance if OE = VIH.
32. If CE1 goes HIGH and CE2 goes LOW simultaneously with WE = VIH, the output remains in a high impedance state.
33. During this period, the I/Os are in output state. Do not apply input signals.
