Frequently Asked Questions
What is the memory size and organization of the Microchip 24AA02/SN?
The 24AA02/SN is a 2K-bit serial EEPROM organized as 256 bytes (256 x 8-bit words). It uses the I2C (Two-Wire) interface with a standard control byte of 1010XXXR, allowing up to eight devices to share the same I2C bus by setting the three address bits via hardware pins.
What is the operating voltage and clock frequency of the 24AA02/SN?
The 24AA02/SN operates at a minimum supply voltage of 1.8 V, making it suitable for low-voltage battery-powered applications. It supports a maximum I2C clock frequency of 400 kHz (Fast Mode), enabling efficient data transfers in real-time embedded systems while maintaining low current consumption.
How durable is the 24AA02/SN in terms of write cycles and data retention?
The 24AA02/SN is rated for 1,000,000 write/erase cycles per memory location, ensuring long service life even in frequently updated data logging applications. Data retention is guaranteed for a minimum of 200 years under normal operating conditions, making it highly reliable for storing critical configuration or calibration data.
What package does the 24AA02/SN come in and is it RoHS compliant?
The 24AA02/SN is available in an 8-pin SOIC (Small Outline Integrated Circuit) package, JESD-30 code R-PDSO-G8, with a standard SOIC-8 manufacturer package code. It is Pb-free with JESD-609 code e3, confirming full RoHS compliance for use in environmentally regulated markets worldwide.
What are typical use cases for the 24AA02/SN EEPROM?
Typical applications include storing device configuration parameters in smart sensors, calibration coefficients in precision measurement equipment, MAC address storage in network devices, and user setting retention in consumer electronics.
