Manufacturer:NEC Description:Automatic backup and write protection of an external SRAM is provided through the VCCO, CEOL , and CEOH pins. The backup energy source used to power the RTC is also used to retain RAM data in the absence of VCC through the VCCO pin. The chip-enable outputs to RAM ( CEOL and CEOH ) are controlled during power transients to prevent data corruption. |
