24FC08T-E/ST

Memory IC Overview

The Microchip Technology 24FC08T-E/ST is an 8-Kbit (1K x 8) serial EEPROM featuring a two-wire I²C interface. It supports clock frequencies up to 1 MHz and offers a maximum access time of 450 ns. The device operates on a single supply voltage ranging from 1.7V to 5.5V and includes a 16-byte page write buffer with a maximum write cycle time of 5 ms. It is housed in an 8-lead TSSOP package and is rated for extended industrial temperature operation from -40°C to +125°C.

Memory IC Feature Summary

• Supports high-speed I²C communication with clock frequencies up to 1 MHz
• Includes hardware write protection via the WP pin to inhibit memory writes
• Features Schmitt trigger inputs and output slope control for noise suppression
• Provides acknowledge polling capability to maximize bus throughput during internal write cycles

Memory IC Applications

• Low-power personal communications devices
• Data acquisition systems requiring non-volatile storage
• Industrial control applications operating at elevated temperatures
• Embedded systems needing configuration data retention

Memory IC Procurement Notes

Verify that the ordering suffix matches the required temperature grade, as the 'E' designation indicates extended temperature range (-40°C to +125°C). Confirm the package type corresponds to the design requirements, specifically the 8-TSSOP form factor. Ensure the voltage supply aligns with the 1.7V to 5.5V operational range specified for this variant. Cross-reference the datasheet revision to confirm compatibility with current manufacturing standards.

Memory IC Selection Notes

Select this component when high-speed I²C performance is required alongside low-voltage operation down to 1.7V. The extended temperature rating makes it suitable for harsh environments where standard industrial parts may fail. Consider the 16-byte page write buffer for efficient data handling compared to byte-write-only alternatives. Verify that the 8-TSSOP package fits within the available PCB footprint constraints.

Memory IC Part Context

This part belongs to the 24XX08 family of serial EEPROMs, which also includes the 24AA08 and 24LC08B variants. While sharing similar memory architecture and interface protocols, the 24FC08 distinguishes itself by supporting higher clock speeds up to 1 MHz. The family utilizes a common control code structure and pinout across various packages, facilitating design flexibility within Microchip's memory portfolio.

Memory IC Replacement Considerations

Direct substitutes include other 24FC08 variants with different packaging options such as SOIC or MSOP. For lower speed requirements, the 24LC08B serves as a compatible alternative but lacks the 1 MHz capability. Ensure any replacement maintains the same voltage range and temperature specifications if environmental conditions remain unchanged.
