AT68166FT

Consumption

Notes:

1. All CSx >VIH

2. All CSx > VCC - 0.3V

3. F = 1/TAVAV, Iout = 0 mA, WEx = OE = VIH, VIN = GND/VCC, VCC max.

4. F = 1/TAVAW, Iout = 0 mA, WEx = VIL, OE = VIH , VIN = GND/VCC, VCC max.

Data Retention

Mode

Atmel CMOS RAM's are designed with battery backup in mind. Data retention voltage and sup-

ply current are guaranteed over temperature. The following rules insure data retention:

1.

During data retention chip select CSx must be held high within V

CC to VCC -0.2V.

2.

Output Enable (OE) should be held high to keep the RAM outputs high impedance, mini-

mizing power dissipation.

3.

During power-up and power-down transitions CSx and OE must be kept between V

CC +

0.3V and 70% of V

CC.

4.

The RAM can begin operation > tR ns after VCC reaches the minimum operation voltages

(3V).
