Data Retention Mode
The CY7C0138AV/144AV/006AV/007AV and CY7C139AV/
145AV/016AV/017AV are designed with battery backup in
mind. Data retention voltage and supply current are guaran-
teed over temperature. The following rules ensure data reten-
tion:
1. Chip enable (CE) must be held HIGH during data retention, with-
in VCC to VCC – 0.2V.
2. CE must be kept between VCC – 0.2V and 70% of VCC
during the power-up and power-down transitions.
3. The RAM can begin operation >tRC after VCC reaches the
minimum operating voltage (3.0 volts).
Notes:
22. tBDD is a calculated parameter and is the greater of tWDD–tPWE (actual) or tDDD–tSD (actual).
23. CE = VCC, Vin = GND to VCC, TA = 25°C. This parameter is guaranteed but not tested.
