24FC04T-I/ST

Memory IC Overview

The Microchip Technology 24FC04T-I/ST is a 4-Kbit Electrically Erasable PROM (EEPROM) organized as two blocks of 256 x 8-bit memory. It operates with a single supply voltage ranging from 1.7V to 5.5V and supports a maximum clock frequency of 1 MHz. The device utilizes an I2C compatible two-wire serial interface and features a 16-byte page write buffer. It is housed in an 8-lead TSSOP package and functions within an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports high-speed 1 MHz operation across the full 1.7V to 5.5V supply voltage range
• Includes hardware write protection via the WP pin to inhibit write operations when tied to VCC
• Features Schmitt trigger inputs and noise suppression filters for reliable data transmission on noisy buses

Memory IC Applications

• Data acquisition systems requiring non-volatile storage
• Personal communications devices needing low-power memory
• Industrial control applications operating within standard temperature ranges

Memory IC Procurement Notes

Verify that the ordering suffix 'ST' corresponds specifically to the 8-lead TSSOP package configuration. Confirm the 'I' designation matches the required industrial temperature range of -40°C to +85°C. Ensure the component meets RoHS compliance requirements for your specific manufacturing process.

Memory IC Selection Notes

Select this part for designs requiring 1 MHz bus speeds at voltages below 2.5V, where the 24LC04B variant is limited to 400 kHz. Consider the 16-byte page write capability for efficient data buffering. Verify that the TSSOP package dimensions fit the available PCB real estate compared to SOIC or SOT-23 alternatives.

Memory IC Part Context

This component belongs to the 24XX04 family of serial EEPROMs, which also includes the 24AA04 and 24LC04B variants. While sharing similar interface protocols and memory organization, the 24FC04 is distinguished by its ability to maintain 1 MHz performance at lower supply voltages starting from 1.7V.

Memory IC Replacement Considerations

The 24FC04T-I/SN serves as a direct package alternative using the 8-lead SOIC format. For designs requiring extended temperature capabilities up to 125°C, the 24FC04E series is the appropriate upgrade path.
