MoBL3™

PRELIMINARY

32M (2M x 16) SRAM

(OE HIGH), or during a write operation (CE LOW and WE

LOW).

Features

• Very high speed: 70 ns

• Advanced low-power MoBL architecture

• Wide voltage range:

Writing to the device is accomplished by taking Chip Enable

(CE) LOW and Write Enable (WE) input LOW. If Byte Low

Enable (BLE) is LOW, then data from I/O pins (I/O₀through

I/O₇), is written into the location specified on the address pins

(A₀through A₂₀). If Byte High Enable (BHE) is LOW, then data

from I/O pins (I/O₈through I/O₁₅) is written into the location

specified on the address pins (A₀through A₂₀).

— V_CCrange: 2.3V – 3.1V

— V_CCQ(I/O) range: 1.7V – V_CC

• Ultra-low active, standby power

• Easy memory expansion with CE and OE features

• 1T SRAM memory cell

• Automatic power-down when deselected

• CMOS for optimum speed/power

Reading from the device is accomplished by taking Chip

Enable (CE) LOW 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 will appear on I/O₀to I/O₇. If Byte High Enable

(BHE) is LOW, then data from memory will appear on I/O₈to

I/O₁₅. See the truth table at the back of this datasheet for a

complete description of read and write modes.

Functional Description^[1]

The MoBL3 is a high-performance CMOS static RAM

organized as 2M 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

can be put into standby mode when deselected (CE HIGH, or

both BLE and BHE HIGH). The input/output pins (I/O₀through

I/O₁₅) are placed in a high-impedance state when: deselected

(CE HIGH, or both BLE and BHE HIGH), outputs are disabled

This SRAM has multiple power down functions. The ZZ pin will

put the SRAM into a deep sleep mode, where the data is not

retained in the SRAM. The Variable Address Mode allows the

user to retain data in a section of the SRAM and reduce the

standby current. The CY81U032X16A9A has the deep sleep

mode disabled on power-up. The VAR register can be used to

enable the deep sleep mode.

The MoBL3 is available in a 48-ball FBGA package.
