CY62187EV30 MoBL^®

64-Mbit (4 M × 16) Static RAM

64-Mbit (4

M × 16) Static RAM

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

(CE₁HIGH or CE₂LOW or both BHE and BLE are HIGH). The

input and output pins (I/O₀through I/O₁₅) are placed in a high

impedance state when: deselected (CE₁HIGH or CE₂LOW),

outputs are disabled (OE HIGH), both Byte High Enable and Byte

Low Enable are disabled (BHE, BLE HIGH), or during a write

operation (CE₁LOW, CE₂HIGH and WE LOW).

Features

■ Very High Speed

❐ 55 ns

■ Wide Voltage Range

❐ 2.2 V to 3.7 V

■ Ultra Low Standby Power

❐ Typical Standby Current: 8 A

❐ Maximum Standby Current: 48 A

■ Ultra Low Active Power

❐ Typical Active Current: 7.5 mA at f = 1 MHz

To write to the device, take Chip Enables (CE₁LOW and CE₂

HIGH) 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

■ Easy Memory Expansion with CE₁, CE_2,and OE Features

■ Automatic Power Down when Deselected

■ CMOS for Optimum Speed and Power

₂₁). 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 A₂₁).

■ Available in Pb-Free 48-ball FBGA Package

To read from the device, take Chip Enables (CE₁LOW 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/O₀to I/O₇. If Byte High Enable (BHE) is LOW, then data from

memory appears on I/O₈to I/O₁₅. See the Truth Table on page

9 for a complete description of read and write modes.
