Frequently Asked Questions
How much non-volatile storage does MCP79412-I/SN provide, and how is it typically used in data-logger designs?
MCP79412-I/SN provides 64 bytes of battery-backed SRAM, which is sufficient to store configuration parameters, calibration data, or event timestamps. In data-logger designs, this memory preserves critical state information across power cycles without an external EEPROM.
Can MCP79412-I/SN interface directly with 1.8 V microcontrollers without level shifting?
Yes. MCP79412-I/SN explicitly supports operation with a 1.8 V nominal supply and I2C communication at 100 kHz, allowing direct connection to modern low-voltage MCUs without the cost or complexity of dedicated level-shift buffers.
What is the lifecycle outlook for MCP79412-I/SN, and what should procurement planners consider?
MCP79412-I/SN has a YTEOL of 13 years, indicating it is in active production with a long remaining lifecycle. The 6-week factory lead time is manageable for most design schedules, and the JESD-609 e3 rating confirms RoHS-compliant, lead-free packaging.
