CY62157EV30 MoBL
8-Mbit (512K × 16) Static RAM
8-Mbit (512K
× 16) Static RAM
Features
Functional Description
■ Thin small outline package (TSOP) I package configurable as
512K × 16 or 1M × 8 static RAM (SRAM)
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).
■ High speed: 45 ns
■ Temperature ranges
❐ Industrial: –40 °C to +85 °C
❐ Automotive-A: –40 °C to +85 °C
❐ Automotive-E: –40 °C to +125 °C
■ Wide voltage range: 2.20 V to 3.60 V
■ Pin compatible with CY62157DV30
■ Ultra low standby power
❐ Typical standby current: 2 A
❐ Maximum standby current: 8 A (Industrial)
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
■ Ultra low active power
❐ Typical active current: 6 mA at f = 1 MHz
A
18). If Byte High Enable (BHE) is LOW, then data from I/O pins
■ Easy memory expansion with CE1, CE2, and OE features
■ Automatic power down when deselected
(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.
■ Complementary Metal Oxide Semiconductor (CMOS) for
optimum speed and power
■ Available in Pb-free and non Pb-free 48-ball very fine-pitch ball
grid array (VFBGA), Pb-free 44-pin thin small outline package
(TSOP) II and 48-pin TSOP I packages

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 512K × 16 SRAM. The 48-pin TSOP I package can also be used as a 1M × 8
SRAM by tying the BYTE signal LOW. In the 1M x 8 configuration, Pin 45 is A19, while BHE, BLE and I/O to I/O pins are not used.

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.

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.
