Product details

70 ns access — what it means for bus timing

The 70 ns access time is the time from address valid to data valid on the bus. The write cycle time is also 70 ns, so read and write timing are symmetric.

Industrial temperature grade — deployment context

Rated for -40°C to 85°C ambient, this part is built for environments where a commercial-grade SRAM would risk data corruption or latch-up.

Lifecycle and sourcing

The DS1230AB-70IND+ carries an Active lifecycle status and is RoHS3 compliant. There is no last-time-buy window or NRND flag, so it remains a viable choice for both new production and ongoing repair of existing designs.

Frequently asked questions

Does the DS1230AB-70IND+ operate at 5V?

Yes, the supply voltage range is 4.75 V to 5.25 V, compatible with standard 5 V logic rails.

Is the DS1230AB-70IND+ RoHS compliant?

Yes, it is RoHS3 compliant.

Can the DS1230AB-70IND+ replace the DS1230Y?

The DS1230AB-70IND+ is a later-generation NVSRAM in the same 32K x 8, 28-pin DIP family. It shares the same footprint and 5 V supply, but verify the specific DS1230Y variant's access time and temperature grade against the 70 ns industrial-rated DS1230AB-70IND+ before substitution.
