package
The CY62137EV30 is a high-performance CMOS static RAM
organized as 128K 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 by 90% when addresses are not toggling.
The device can also be put into standby mode reducing power
consumption by more than 99% when deselected (CE HIGH
or both BLE and BHE are HIGH). The input/output pins (I/O0
through I/O15) are placed in a high-impedance state when:
deselected (CE HIGH), outputs are disabled (OE HIGH), both
Byte High Enable and Byte Low Enable are disabled (BHE,
BLE HIGH), or during a write operation (CE LOW and WE
LOW).
Writing to the device is accomplished by asserting Chip Enable (CE) 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 A16). 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 A16).
Reading from the device is accomplished by asserting Chip
Enable (CE) 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 will appear on I/O0 to I/O7. If Byte High Enable (BHE) is
LOW, then data from memory will appear on I/O8 to I/O15. See
the truth table at the back of this data sheet for a complete
description of read and write modes.
The CY62137EV30 is available in 48-ball VFBGA and 44-pin
TSOPII packages.

Notes:
10. BHE.BLE is the AND of both BHE and BLE. The chip can be deselected by either disabling the chip enable signals or by disabling both BHE and BLE.
11. Test conditions for all parameters other than tri-state parameters assume signal transition time of 3 ns (1V/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 “AC Test Loads and Waveforms” section.
12. At any given 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
given device.
13. tHZOE, tHZCE, tHZBE, and tHZWE transitions are measured when the outputs enter a high- impedance state.
14. The internal Write time of the memory is defined by the overlap of WE, CE = VIL, BHE and/or BLE = 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.
