DS Datasheet pdf – Nonvolatile Controller Chip – Dallas Semiconductor

The DS constantly monitors the incoming. The second function which the. A battery status warning will occur. The third function of write protection is accomplished by holding the CEO output signal to.

Provides for Redundant Batteries. Optional Industrial N Temperature Range of.


The delay of write protection until. First, a switch is provided to direct power from the battery or the incoming supply V CCI depending on. The DS controller provides an internal isolation switch which.

Battery status can, therefore, be determined by. DS datasheef DIP mil. Special circuitry uses a low. If the battery voltage is less than.

The switch to a. When such a condition is detected, chip enable is inhibited to accomplish write protection and. If one battery should fail, the other will take over the load. The BAT2 battery pin must be grounded. In applications where battery redundancy is not required, a single battery should be connected to. CEO will follow CE with a maximum propagation delay of 20ns. Figure 1 shows a typical application incorporating the DS in a microprocessor-based system.

DS is recognized by Underwriters Laboratory U. All voltages are referenced to ground. If CE input is low at datashee time power-fail detection occurs. CE High to Power-Fail. I CC01 is the maximum average load which the DS can supply to datashdet memories. Incoming power is monitored for an out-of-tolerance. Tests Battery Condition on Power up.

Voltage on Datasbeet Pin Relative to Ground. Power-fail detection occurs in the. The fourth function the DS C for N parts. Recovery at Power Up.


During nominal supply conditions. A grounded V BAT2 pin will not activate a battery-fail. CEO can only sustain leakage current in the battery backup mode. For industrial products Nthis range is ?

Unused battery inputs must be grounded. The nonvolatile controller contains circuitry to. This switch has a voltage drop of less than 0. This is to maintain the battery s at its d1210 capacity until the equipment is. The fifth function of the nonvolatile controller provides for battery.

In many applications, data integrity is paramount. This is a stress rating only and functional operation of the device at these or any other conditions.

When the supply goes out of tolerance a precision comparator detects power-fail and inhibits chip. A subsequent write cycle can then be executed to the same memory location altering the data. Only one battery input is required.
