24FC16-E/ST

Memory IC Overview

The Microchip Technology 24FC16-E/ST 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, supporting clock frequencies up to 1 MHz at supply voltages between 1.7V and 5.5V. The device utilizes low-power CMOS technology, ensuring standby currents of 3 μA maximum in extended temperature ranges. It includes a 16-byte page write buffer, hardware write-protect capabilities via the WP pin, and Schmitt trigger inputs for noise suppression.

Memory IC Feature Summary

• Supports high-speed 1 MHz I2C communication within specified voltage ranges
• Includes a 16-byte page write buffer for efficient data transfer
• Features hardware write protection controlled by the WP pin state
• Provides Schmitt trigger inputs to suppress bus noise spikes

Memory IC Applications

• Data logging systems requiring non-volatile storage
• Configuration parameter storage in embedded controllers
• Calibration data retention in industrial sensors
• Device identification and serial number storage

Memory IC Procurement Notes

Verify that the ordering suffix 'ST' corresponds specifically to the TSSOP-8 package type required for your PCB layout. Confirm the 'E' designation indicates the Extended temperature range (-40°C to +125°C) suitable for your operating environment. Ensure the system design accommodates the specific I2C pull-up requirements for 1 MHz operation.

Memory IC Selection Notes

Select this component when high-speed 1 MHz I2C access is necessary compared to slower 400 kHz alternatives. It is appropriate for designs requiring operation down to 1.7V, unlike the 24LC16B which requires a minimum of 2.5V. Consider the TSSOP-8 package if space constraints favor surface-mount technology over through-hole options.

Memory IC Part Context

This part belongs to the 24XX16 family of 16-Kbit EEPROMs from Microchip Technology. It shares architectural similarities with the 24AA16 and 24LC16B but distinguishes itself through support for higher clock frequencies up to 1 MHz. The family offers various package options including MSOP, SOIC, and SOT-23 to suit different form factors.

Memory IC Replacement Considerations

The 24FC16T-E/ST serves as a tape-and-reel variant of this component. For lower speed requirements, the 24LC16B-E/ST is an alternative but operates at a maximum of 400 kHz and requires a minimum voltage of 2.5V.
