CY62148GN MoBL®
4-Mbit (512K × 8) Static RAM
Cypress Semiconductor Corporation 198 Champion Court San Jose,CA 95134-1709 408-943-2600
Document Number: 001-95418 Rev. *D Revised December 21, 2017
4-Mbit (512K × 8) Static RAM
Features
Very high speed: 45 ns
Wide voltage range: 2.2 V to 3.6 V, 4.5 V to 5.5 V
Ultra low standby power
Typical standby current: 3.5 µA
Maximum standby current: 8.7 µA
Easy memory expansion with CE and OE features
Automatic power-down when deselected
Complementary metal oxide semiconductor (CMOS) for
optimum speed and power
Available in Pb-free 32-pin thin small outline package (TSOP) II
and 32-pin small-outline integrated circuit (SOIC) packages
Functional Description
The CY62148GN is a high-performance CMOS static RAM
organized as 512K words by 8-bits. This device features
advanced circuit design to provide ultra low standby 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
addresses are not toggling. Placing the device in standby mode
reduces power consumption by more than 99% when deselected
(CE HIGH). The eight input and output pins (I/O0 through I/O7)
are placed in a high-impedance state when the device is
deselected (CE HIGH), Outputs are disabled (OE HIGH), or
during an active Write operation (CE LOW and WE LOW).
To write to the device, take Chip Enable (CE) and Write Enable
(WE) inputs LOW. Data on the eight I/O pins (I/O0 through I/O7)
is then written into the location specified on the address pins (A0
through A18).
To read from the device, take Chip Enable (CE) and Output
Enable (OE) LOW while forcing Write Enable (WE) HIGH. Under
these conditions, the contents of the memory location specified
by the address pins appear on the I/O pins.

Notes
15. 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.
16. At any temperature and voltage condition, tHZCE is less than tLZCE, tHZOE is less than tLZOE, and tHZWE is less than tLZWE for any device.
17. tHZOE, tHZCE, and tHZWE transitions are measured when the outputs enter a high impedance state.
18. The internal wre.ite time of the memory is defined by the overlap of WE, CE = 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 setup and hold timing should be referenced to the edge of the signal that terminates the write.
19. The minimum write cycle pulse width for Write Cycle No. 3 (WE controlled, OE LOW) should be equal to the sum of tSD and tHZWE.
