Data Retention Mode
The CY7C027/028 and CY7C037/038 are designed with
battery backup in mind. Data retention voltage and supply
current are guaranteed over temperature. The following rules
ensure data retention:
1. Chip enable (CE) must be held HIGH during data retention,
within 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 (4.5 volts).

Notes:
21. tBDD is a calculated parameter and is the greater of tWDD–tPWE (actual) or tDDD–tSD (actual).
22. CE = VCC, Vin = GND to VCC, TA = 25°C. This parameter is guaranteed but not tested.
