24FC04-E/P

Memory IC Overview

The Microchip Technology 24FC04-E/P is a 4-Kbit Electrically Erasable PROM (EEPROM) organized as two blocks of 256 x 8-bit memory. It features a Two-Wire Serial Interface compatible with I²C protocols and supports clock frequencies up to 1 MHz across a supply voltage range of 1.7V to 5.5V. The device utilizes low-power CMOS technology, drawing a maximum active read current of 1 mA and standby current of 3 µA at extended temperatures. It operates within an industrial temperature range of -40°C to +125°C and is housed in an 8-pin PDIP package.

Memory IC Feature Summary

• Supports high-speed serial data transmission with clock frequencies reaching 1 MHz
• Includes hardware write-protect functionality via the WP pin for array security
• Features Schmitt trigger inputs and output slope control to suppress noise and ground bounce
• Provides self-timed erase/write cycles with a 16-byte page write buffer

Memory IC Applications

• Data logging in industrial monitoring systems
• Configuration storage for embedded controllers
• Parameter retention in battery-backed circuits
• Device identification and calibration data storage

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required temperature grade and package style. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design specifications align with the electrical characteristics defined in the datasheet for the Extended temperature variant.

Memory IC Selection Notes

Select this component when operation below 2.5V is required alongside high-speed 1 MHz communication capabilities. The Extended temperature rating makes it suitable for harsh environments where standard industrial grades are insufficient. Compare against the 24LC04B if lower speed is acceptable but higher minimum voltage is permissible.

Memory IC Part Context

This part belongs to the 24XX04 family of serial EEPROMs from Microchip Technology. It shares architectural similarities with the 24AA04 and 24LC04B but offers distinct performance advantages regarding voltage range and clock speed. The family provides non-volatile memory solutions for applications requiring frequent data updates.

Memory IC Replacement Considerations

The 24FC04T-E/OT serves as a surface-mount alternative within the same functional family. Verify interface compatibility and voltage requirements when substituting packages.
