24C02A-E/J

Memory IC Overview

The Microchip Technology 24C02A-E/J is a 2-kbit (256 x 8) serial Electrically Erasable Programmable Read-Only Memory (EEPROM). It operates exclusively at 5.0V and utilizes a two-wire I2C compatible interface with a maximum clock frequency of 400 kHz. The device features hardware write protection, self-timed write cycles, and a page-write buffer. It guarantees 1,000,000 erase/write cycles and data retention exceeding 200 years. The component is housed in an 8-pin SOIC package and supports industrial temperature ranges.

Memory IC Feature Summary

• Hardware write protect mechanism for data security
• Self-timed write cycle with auto-erase capability
• Page-write buffer for efficient data transfer
• I2C compatible two-wire serial interface

Memory IC Applications

• Smart card applications requiring non-volatile storage
• Industrial control systems needing parameter retention
• Embedded devices storing calibration data

Memory IC Procurement Notes

Verify the specific suffix 'E' indicates the extended temperature range (-40°C to +125°C) as per official datasheets. Confirm the 'J' suffix corresponds to the 8-pin SOIC package. Ensure compatibility with 5.0V-only operation requirements. Check current production status as legacy variants may be discontinued.

Memory IC Selection Notes

Select this part for designs strictly operating at 5.0V. The 24C02A-E/J is suitable for environments requiring high reliability and long data retention. Consider the 8-pin SOIC package constraints for PCB layout. Verify that the I2C bus speed requirements do not exceed 400 kHz.

Memory IC Part Context

This component belongs to the 24C02A series of 5.0V I2C EEPROMs from Microchip Technology. It shares functional similarities with other 2K-bit serial memories but is distinct due to its fixed 5.0V supply requirement. The series is widely used in legacy and robust industrial applications where voltage stability is maintained.

Memory IC Replacement Considerations

Direct substitutes include the 24C02B series or AT24C02D for wider voltage support. For identical 5.0V operation, check availability of 24C02A-I/J for industrial temperature grades. Verify pinout compatibility before substitution.
