CY62177EV18 MoBL®  
32-Mbit (2 M × 16 / 4 M × 8) Static RAM  
32-Mbit (2  
M × 16 / 4 M × 8) Static RAM  
Features  
Functional Description  
■ Thin small outline package (TSOP) I configurable as 2 M × 16  
or as 4 M × 8 static RAM (SRAM)  
The CY62177EV18 is a high-performance CMOS static RAM  
organized as 2 M words by 16 bits and 4 M words by 8 bits. This  
device features advanced circuit design to provide ultra low  
active current. It 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 99 percent when  
addresses are not toggling. The device can also be put into  
standby mode when deselected (CE1 HIGH or CE2 LOW or both  
BHE and BLE are HIGH). The input and output pins (I/O0 through  
I/O15) are placed in a high impedance state when: deselected  
(CE1HIGH or CE2 LOW), outputs are disabled (OE HIGH), both  
Byte High Enable and Byte Low Enable are disabled (BHE, BLE  
HIGH), or during a write operation (CE1 LOW, CE2 HIGH and WE  
LOW).  
■ Very high speed  
❐ 70 ns  
■ Wide voltage range  
❐ 1.65 V to 2.25 V  
■ Ultra low standby power  
❐ Typical standby current: 3 A  
❐ Maximum standby current: 25 A  
■ Ultra low active power  
❐ Typical active current: 4.5 mA at f = 1 MHz  
■ Easy memory expansion with CE1, CE2, and OE Features  
■ Automatic power-down when deselected  
To write to the device, take Chip Enables (CE1 LOW and CE2  
HIGH) and Write Enable (WE) input 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  
A20). If Byte High Enable (BHE) is LOW, then data from I/O pins  
(I/O8 through I/O15) is written to the location specified on the  
address pins (A0 through A20). To read from the device, take  
Chip Enables (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 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 48-ball TSOP I and 48-ball FBGA package  
Pin #13 of the 48 TSOP I package is an DNU pin that must be  
left floating at all times to ensure proper application.
