VCCO NC – RAM Supply – No Connection CEI – Chip Enable Input WEI – Write Enable Input CEO – Chip Enable Output to RAM WEO – Write Enable Output to RAM GND – Ground PF – Power Fail Output A0-A3 – Address Inputs VBAT VCCI – Battery Input – +5V Supply DESCRIPTION The DS1234 is a CMOS circuit that converts CMOS RAM into nonvolatile memory and adds two software selectable switches.
Ining power is monitored for an out-of-tolerance condition.
When such a condition is detected, chip enable and write enable to the RAM are inhibited to acplish write protection, and the battery is switched on to supply the memory with uninterrupted power.
