Its 70 ns access time is the cycle-limiting spec for read and write operations: a 70 ns window means the memory can complete a data transfer within that period, which sets the bus timing margin for the host controller. For a microcontroller with a 12.5 MHz or slower external bus, this part fits without wait states; faster controllers may need to insert one or more wait cycles to meet the 70 ns requirement. ## NVSRAM: SRAM speed with non-volatile retention NVSRAM technology combines the fast read/write of a standard SRAM with an internal lithium battery and shadow EEPROM array. On power loss, the SRAM content is automatically copied to the EEPROM; on power-up, it is restored. This gives unlimited write endurance during normal operation (no wear-leveling needed) and data retention for years without power. The 70 ns write cycle time matches the read access time, so back-to-back writes run at full bus speed — unlike serial EEPROM or Flash, which have much longer write cycles. ## Industrial temperature grade and package Rated for -40°C to 85°C ambient, the DS1245Y-70IND+ is suited for industrial control, outdoor telecom, and automotive cabin applications where temperature extremes occur. The 32-pin EDIP (0.600\" body, 15.24 mm pitch) is a through-hole module that includes the battery and controller in one sealed package. The 'IND' suffix in the ordering code designates the industrial temperature range; the '+' indicates RoHS3 compliance. ## Lifecycle and supply posture It is RoHS3 compliant. For BOM planning, this part can be specified into new designs without last-time-buy risk.","metaTitle":"DS1245Y-70IND+ NVSRAM, 1Mbit, 70 ns, Parallel, 32-EDIP","metaDescription":"DS1245Y-70IND+ 1Mbit NVSRAM with 70 ns access time, parallel interface, -40°C to 85°C industrial temp, 32-EDIP.

The DS1245Y-70IND+ is the industrial temperature (-40°C to 85°C) variant.

Standard SRAM loses all data on power loss. NVSRAM eliminates the need for external battery-backed SRAM or serial EEPROM with wear-leveling concerns."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/DS1245Y-70IND","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/DS1245Y-70IND when reusing this data.
