MoBL^

8-Mbit (1024K x 8) MoBL^Static RAM

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. The device can be put into

standby mode reducing power consumption by 85% when

deselected (CE₁HIGH or CE₂LOW).

Features

• Very high speed: 45 ns, 55 ns and 70 ns

— Wide voltage range: 2.20V – 3.60V

• Ultra-low active power

— Typical active current:1.5 mA @ f = 1 MHz

— Typical active current: 12 mA @ f = f_max

• Ultra-low standby power

Writing to the device is accomplished by taking Chip Enable 1

(CE₁) and Write Enable (WE) inputs LOW and Chip Enable 2

(CE₂) HIGH. Data on the eight I/O pins (I/O₀through I/O₇) is

then written into the location specified on the address pins (A₀

• Easy memory expansion with CE₁, CE₂, and OE

through A₁₉).

features

Reading from the device is accomplished by taking Chip

Enable 1 (CE₁) and Output Enable (OE) LOW and Chip

Enable 2 (CE₂) HIGH while forcing Write Enable (WE) HIGH.

Under these conditions, the contents of the memory location

specified by the address pins will appear on the I/O pins.

The eight input/output pins (I/O₀through I/O₇) are placed in a

high-impedance state when the device is deselected (CE₁

LOW and CE₂HIGH), the outputs are disabled (OE HIGH), or

during a write operation (CE₁LOW and CE₂HIGH and WE

LOW). See the truth table for a complete description of read

and write modes.

• Automatic power-down when deselected

• CMOS for optimum speed/power

• Packages offered in a 48-ball BGA, 48-pin TSOPI, and

44-pin TSOPII

Functional Description^[1]

The CY62158DV30 is a high-performance CMOS static RAMs

organized as 1024K words by 8 bits. This device features

advanced circuit design to provide ultra-low active current.
