24AA16-E/SN

Memory IC Overview

The Microchip Technology 24AA16-E/SN is a 16-Kbit Electrically Erasable PROM organized as eight blocks of 256 x 8-bit memory. It features a two-wire serial interface compatible with I2C protocols. The device operates on a single supply voltage ranging from 1.7V to 5.5V and supports clock frequencies up to 400 kHz at voltages above 2.5V, or 100 kHz below 2.5V. It utilizes low-power CMOS technology with maximum standby current of 1 μA and read current of 1 mA. The component includes a 16-byte page write buffer, hardware write-protect capability via the WP pin, and Schmitt trigger inputs for noise suppression.

Memory IC Feature Summary

• Supports bidirectional data transmission using a standard two-wire serial bus protocol
• Includes hardware write protection controlled by the state of the WP pin
• Features internal address pointer for sequential read and write operations
• Provides acknowledge polling capability to determine write cycle completion

Memory IC Applications

• Data logging in industrial control systems
• Configuration storage for embedded microcontrollers
• Parameter retention in consumer electronics devices

Memory IC Procurement Notes

Verify that the ordering suffix 'SN' corresponds to the SOIC-8 package type required for the design. Confirm the 'E' suffix indicates the extended temperature range specification suitable for the operating environment. Ensure compatibility with the system's I2C bus voltage levels and pull-up resistor requirements before finalizing procurement.

Memory IC Selection Notes

Select this component when an I2C-compatible EEPROM with 16-Kbit capacity is required. The extended temperature grade ensures reliability in high-heat environments. The SOIC-8 package facilitates surface-mount assembly. Consider the 1.7V minimum operating voltage for low-power applications compared to other variants requiring higher supply voltages.

Memory IC Part Context

This part belongs to the 24XX16 family of serial EEPROMs manufactured by Microchip Technology. The family shares common functional characteristics but varies in voltage ranges and speed capabilities. The 24AA16 variant specifically supports operation down to 1.7V, distinguishing it from the 24LC16B which requires a minimum of 2.5V. The device is designed for non-volatile data storage in space-constrained electronic systems.

Memory IC Replacement Considerations

The 24AA16-I/SN serves as a direct substitute offering identical electrical specifications but within the industrial temperature range instead of the extended range.
