24FC08-E/ST

Memory IC Overview

The Microchip Technology 24FC08-E/ST is an 8-Kbit (1K x 8) Electrically Erasable PROM (EEPROM) featuring a two-wire I²C compatible serial interface. It supports clock frequencies up to 1 MHz across a supply voltage range of 1.7V to 5.5V, with a maximum access time of 450 ns. The device operates within an extended temperature range of -40°C to +125°C and utilizes an 8-lead TSSOP surface-mount package.

Memory IC Feature Summary

• Supports high-speed 1 MHz I²C communication for efficient data transfer
• Includes a 16-byte page write buffer to optimize write operations
• Features hardware write protection via the WP pin to secure memory content
• Provides Schmitt trigger inputs and output slope control for noise suppression

Memory IC Applications

• Data logging in industrial environments requiring extended temperature stability
• Configuration storage for embedded systems operating at low voltages
• Parameter retention in consumer electronics utilizing I²C buses

Memory IC Procurement Notes

Verify that the ordering suffix 'E' corresponds to the Extended temperature grade (-40°C to +125°C) and 'ST' indicates the 8-lead TSSOP package. Confirm the specific revision level matches your design requirements, as datasheet parameters may be updated over time. Ensure compatibility with your system's I²C bus voltage levels and pull-up resistor configurations.

Memory IC Selection Notes

Select this component when operation below 2.5V is required alongside high-speed 1 MHz performance. The Extended temperature grade is necessary for applications exposed to high ambient heat. Compare against the Industrial grade variant if lower thermal stress is expected, or the 24LC08B if a minimum 2.5V supply is guaranteed.

Memory IC Part Context

This part belongs to the 24XX08 family of 8-Kbit EEPROMs from Microchip Technology. It shares functional similarities with the 24AA08 and 24LC08B but offers distinct electrical characteristics, specifically higher speed and lower voltage operation capabilities compared to other family members.

Memory IC Replacement Considerations

Direct substitutes include the 24AA08 and 24LC08B, provided their respective voltage and speed constraints align with the application. Verify package compatibility and temperature ratings before swapping.
