Product details

2Kbit I2C EEPROM in an 8-TSSOP — what this part covers

The Microchip 34AA02T-E/ST is a 2Kbit serial EEPROM with an I²C interface, organized as 256 x 8 bits. It operates from a single 1.7V to 5.5V supply, making it a drop-in for 1.8V, 3.3V, or 5V logic rails without a level shifter. The 400 kHz clock frequency matches the standard I²C fast-mode bus speed used by most microcontrollers.

The extended temperature range also covers outdoor telecom cabinets and factory-floor sensors that see thermal cycling.

It is ROHS3 compliant.

Frequently asked questions

Is 34AA02T-E/ST compatible with 1.8V logic?

Yes, the 1.7V minimum supply voltage means it operates directly on a 1.8V rail, and the I²C interface is fully compatible with 1.8V logic levels.

Does 34AA02T-E/ST support 400 kHz I2C?

Yes, the clock frequency is rated at 400 kHz, which is the standard I²C fast-mode speed.

What is the write cycle time for 34AA02T-E/ST?

The write cycle time is 5 ms per word or page write operation.
