addresses are not toggling. Place the device into standby mode
when deselected (CE HIGH 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 (CE HIGH), the
outputs are disabled (OE HIGH), both the Byte High Enable and
the Byte Low Enable are disabled (BHE, BLE HIGH), or during
an active write operation (CE LOW and WE LOW).
Features
■ Very high speed: 45 ns
■ Wide voltage range: 2.2 V to 3.6 V and 4.5 V to 5.5 V
■ Ultra low standby power
❐ Typical Standby current: 2 A
❐ Maximum Standby current: 8 A
To write to the device, take 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 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).
■ Ultra low active power
❐ Typical active current: 1.8 mA at f = 1 MHz
■ Easy memory expansion with CE and OE features
■ Automatic power down when deselected
To read from the device, take 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 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 the Truth Table on page 11 for a
complete description of read and write modes.
■ Complementary metal oxide semiconductor (CMOS) for
optimum speed and power
■ Available in Pb-free 44-pin thin small outline package (TSOP) II
package
Functional Description
The CY62157ESL device is suitable for interfacing with
processors that have TTL I/P levels. It is not suitable for
processors that require CMOS I/P levels. Please see Electrical
Characteristics on page 4 for more details and suggested
alternatives.
The CY62157ESL 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. The device also has an automatic power down
feature that significantly reduces power consumption when

Notes
15. 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 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.
16. Test conditions for all parameters other than tri-state parameters assume signal transition time of 3 ns or less, timing reference levels of 1.5 V, input pulse levels of 0
to 3 V, and output loading of the specified IOL/IOH as shown in the Figure 2 on page 5.
17. At any temperature and voltage condition, t
is less than t

19. If both byte enables are toggled together, this value is 10 ns.
20. The internal write time of the memory is defined by the overlap of WE, CE = V , BHE, BLE or both = V . All signals must be active to initiate a write and any of these
IL
IL
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.
21. The minimum write cycle pulse width for Write Cycle No. 4 (WE controlled, OE LOW) should be equal to the sum of tSD and tHZWE.
