CEO can only sustain leakage current in the battery backup mode. A subsequent write cycle can then be executed to the same memory location altering the data. During nominal supply conditions. The BAT2 battery pin must be grounded. In applications where battery redundancy is not required, a single battery should be connected to.

This is to maintain the battery s at its highest capacity until the equipment is. Battery status can, therefore, be determined by. The third function of write protection is accomplished by holding the CEO output signal to.


DS 8-pin DIP mil. C for N parts.

In these applications it is often desirable to. The delay of write protection until. CEO will follow CE with a maximum propagation delay of 20ns. For industrial products Nthis range is ? If one battery should fail, the other will take over the load.

This is a stress rating only and functional operation of the device at these or any other conditions. In many applications, data integrity is paramount. If CE input is low at the time power-fail detection occurs. Only one battery input is required. When the supply goes out of tolerance a precision comparator detects power-fail and inhibits chip. When such a condition is detected, chip enable is inhibited to accomplish write protection and.

The DS constantly monitors the incoming. Figure 1 shows a typical application incorporating the DS in a microprocessor-based system.

The fifth function of the nonvolatile controller provides for battery. I CC01 is the maximum average load which the DS can supply to the memories. The second function which the. The DS controller provides an internal isolation switch which.


All voltages are referenced to ground. The switch to a. This switch has a voltage drop of less than 0. Tests Battery Condition on Power up.

A grounded V BAT2 pin will not activate a battery-fail. Each time that the circuit is. A battery status warning will occur. Automatically Switches to Battery when. Power-fail detection occurs in the. Unused battery inputs must datashert grounded. First, a switch is provided to direct power from the battery or the incoming supply V CCI depending on. Optional Industrial N Temperature Range of.

All AC and DC electrical characteristics are valid for the full temperature range. Voltage on Any Pin Relative to Ground. Measured with a load as shown in Figure 2. Provides for Redundant Batteries. CE High to Power-Fail.

The nonvolatile controller contains circuitry to.
