About Serial EEPROM ICs

Serial EEPROM (Electrically Erasable Programmable Read-Only Memory) integrated circuits are a class of non-volatile memory used for storing small amounts of data that must be retained when power is removed. Unlike parallel EEPROMs, they use a serial interface (such as I²C, SPI, or Microwire), which significantly reduces pin count and board space requirements while simplifying system design.

These memory ICs are essential components in countless electronic systems where reliable, rewritable storage of configuration data, calibration constants, or user settings is required. Their durability (typically supporting 1,000,000+ write cycles), data retention (often 200 years), and low power consumption make them indispensable in modern electronics design across consumer, industrial, automotive, and medical applications.

Packaging Options

This EEPROM memory IC is available from PCX in multiple packaging formats to suit your production needs, including Tape & Reel (TR) for automated assembly, Cut Tape (CT) for prototyping and small batches, and Digi-Reel® packaging for flexible reel quantities.

Frequently Asked Questions

Question: What is the difference between the 93LC46BT-I/SN and other variants in the 93LC46 series?

Answer: The “BT” suffix indicates the industrial temperature grade (-40°C to 85°C), while the “I/SN” denotes the 8-SOIC package. Other variants may have different temperature ratings or package types.

Question: Is this EEPROM compatible with 3.3V and 5V systems?

Answer: Yes, the wide 2.5V to 5.5V operating voltage range makes it compatible with both 3.3V and 5V systems without requiring level shifting.

Question: How many write cycles can this EEPROM endure?

Answer: This device typically endures 1,000,000 erase/write cycles, ensuring long-term reliability for frequently updated data.

Question: What is the data retention period for this memory IC?

Answer: The 93LC46BT-I/SN offers a minimum data retention of 200 years, ensuring your stored data remains intact for the lifetime of your product.

Question: Can I use this EEPROM in automotive applications?

Answer: While it has an industrial temperature rating, for full automotive qualification, you would need to verify specific AEC-Q100 graded versions from Microchip’s automotive product line.

Question: What packaging options are available for prototyping versus production runs?

Answer: For prototyping, Cut Tape (CT) is ideal. For production, Tape & Reel (TR) is recommended for automated pick-and-place assembly. PCX can supply both options.
