24FC04H-I/MS

Memory IC Overview

The Microchip Technology 24FC04H-I/MS 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, supporting clock frequencies up to 1 MHz across the full supply voltage range of 1.7V to 5.5V. The device operates within an industrial temperature range of -40°C to +85°C and utilizes low-power CMOS technology with standby currents as low as 1 µA. It includes hardware write-protect functionality for half the array and supports page writes of up to 16 bytes.

Memory IC Feature Summary

• Supports high-speed I2C communication with clock compatibility up to 1 MHz
• Includes hardware write-protect capability for the upper half of the memory array
• Features Schmitt trigger inputs and output slope control for noise suppression
• Provides self-timed erase/write cycles with automatic termination

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 ordering suffix matches the required package type and temperature grade. Confirm the specific revision level against the manufacturer's latest datasheet to ensure pinout and electrical characteristics remain consistent. Check for any recent product change notices regarding material composition or manufacturing location changes.

Memory IC Selection Notes

Select this component when a 4-Kbit capacity is sufficient and high-speed 1 MHz I2C operation is required at low voltages. Ensure the application environment stays within the specified industrial temperature limits. Consider the half-array write-protect feature if partial memory security is needed without software overhead.

Memory IC Part Context

This part belongs to the 24XX04H family of serial EEPROMs from Microchip Technology. It shares architectural similarities with the 24AA04H and 24LC04BH but offers higher clock speed compatibility. The 'I' designation indicates the industrial temperature range, while '/MS' specifies the 8-lead MSOP package.

Memory IC Replacement Considerations

Direct substitutes include other 24FC04H variants with different packages such as 24FC04H-I/P or 24FC04H-I/SN. Cross-family replacements like 24AA04H are limited to 400 kHz operation.
