CY62136CV30/33 MoBL

CY62136CV MoBL

2M (128K x 16) 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 by 80% when addresses are not

toggling. The device can also be put into standby mode

reducing power consumption by more than 99% when

deselected (CE HIGH). The input/output pins (I/O₀through

Features

• Very high speed: 55 ns and 70 ns

• Voltage range:

— CY62136CV30: 2.7V–3.3V

— CY62136CV33: 3.0V–3.6V

— CY62136CV: 2.7V–3.6V

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

(CE HIGH), outputs are disabled (OE HIGH), both Byte High

Enable and Byte Low Enable are disabled (BHE, BLE HIGH),

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

• Pin-compatible with the CY62136V

• Ultra-low active power

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

Writing to the device is accomplished by taking Chip Enable

(CE) and Write Enable (WE) inputs 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 (A₀

through A₁₆). 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 A₁₆).

— Typical active current: 5.5 mA @ f = f_max(70-ns

speed)

• Low standby power

• Easy memory expansion with CE and OE features

• Automatic power-down when deselected

• CMOS for optimum speed/power

• Packages offered in a 48-ball FBGA

Reading from the device is accomplished by taking Chip

Enable (CE) 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 data sheet for a complete

description of read and write modes.

Functional Description^[1]

The and CY62136CV are high-performance CMOS static

RAM organized as 128K words by 16 bits. This device features

advanced circuit design to provide ultra-low active current.
