24AA16/P

Memory IC Overview

The Microchip Technology 24AA16/P 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 that threshold. It includes hardware write protection via the WP pin, Schmitt trigger inputs for noise suppression, and output slope control to eliminate ground bounce.

Memory IC Feature Summary

• Supports bidirectional data transmission over a two-wire serial bus using standard I²C protocol
• Includes a 16-byte page write buffer to optimize write operations across memory blocks
• Features hardware write protection controlled by the WP pin to inhibit array writes when tied high
• Incorporates Schmitt trigger inputs and filter circuits to suppress noise spikes on the SCL and SDA lines

Memory IC Applications

• Embedded systems requiring non-volatile storage for configuration parameters
• Industrial control devices needing reliable data retention in noisy environments
• Low-power consumer electronics operating on variable supply voltages
• Automotive applications utilizing AEC-Q100 qualified components

Memory IC Procurement Notes

Verify the specific temperature grade and package type against project requirements before ordering. Confirm that the Industrial temperature range (-40°C to +85°C) aligns with environmental conditions. Ensure the PDIP-8 through-hole package matches the PCB footprint design. Check for RoHS compliance status if required by regulatory standards. Validate supply voltage compatibility with the target system's power rails.

Memory IC Selection Notes

Select this component for designs requiring low standby current and wide voltage operation down to 1.7V. Consider the 400 kHz maximum clock frequency for moderate-speed I²C communication needs. Evaluate the 1 million erase/write cycle endurance for long-term reliability. Note that address pins A0-A2 are not used internally, limiting multi-device addressing on a single bus compared to other EEPROM families.

Memory IC Part Context

This part belongs to the 24XX16 family of serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with the 24LC16B and 24FC16 but differs in minimum operating voltage and maximum clock speed specifications. The PDIP-8 suffix indicates an 8-lead Plastic Dual In-Line Package suitable for through-hole mounting.

Memory IC Replacement Considerations

The 24LC16B serves as a direct functional replacement within the same datasheet specification, though it requires a minimum supply voltage of 2.5V instead of 1.7V. The 24FC16 offers higher speed capabilities up to 1 MHz but may have different electrical characteristics. Verify voltage tolerance and package availability when substituting.
