24AA014T-I/MNY

Memory IC Overview

The Microchip Technology 24AA014T-I/MNY is a 1 Kbit (128 x 8) Serial Electrically Erasable PROM featuring a 2-Wire I²C compatible interface. It operates on a single supply voltage ranging from 1.7V to 5.5V with a maximum clock frequency of 400 kHz. The device utilizes low-power CMOS technology, drawing typical active current of 1 mA and standby current of 1 µA at 5.5V. It supports page write buffers for up to 16 bytes and includes hardware write protection for the entire array. Packaged in an 8-lead TDFN format, it functions within an industrial temperature range of -40°C to +85°C.

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm the voltage range requirements align with the 1.7V to 5.5V operational specifications. Ensure the design accommodates the necessary pull-up resistors for the SDA and SCL lines to maintain signal integrity during bus transactions.

Memory IC Selection Notes

Select this component when a compact 1 Kbit EEPROM solution is required for I²C bus integration. It is suitable for designs operating at voltages as low as 1.7V where power efficiency is critical. Consider the TDFN package for space-constrained PCB layouts while ensuring adequate thermal management within the specified industrial temperature limits.

Memory IC Part Context

This part belongs to the 24AA014/24LC014 family of serial EEPROMs manufactured by Microchip Technology. The 'I' designation indicates an industrial temperature rating, while the 'MNY' suffix specifies the 8-lead TDFN package variant. This series is designed for applications requiring reliable non-volatile memory with standard two-wire serial interface protocols.

Memory IC Replacement Considerations

Cross-reference with other 24AA014 variants such as 24AA014T-I/MC or 24AA014H-I/MNY if different package footprints are needed. Verify that substitute parts maintain the same 1.7V minimum operating voltage and 400 kHz clock speed capabilities.

Memory IC FAQ

How does the hardware write protection function?

The WP pin controls write protection; tying it to VCC inhibits all write operations to the array, while connecting it to VSS enables them.

What is the maximum page write size?

The device features a page write buffer that allows the transmission of up to 16 bytes before a Stop condition initiates the internal write cycle.
