24LC04BT-E/ST

Memory IC Overview

The Microchip Technology 24LC04BT-E/ST 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 maximum clock frequencies up to 400 kHz for operation within the 2.5V to 5.5V supply voltage range. The device utilizes low-power CMOS technology and operates across an extended temperature range from -40°C to +125°C. It is housed in an 8-lead TSSOP package.

Memory IC Feature Summary

• Supports bidirectional data transmission via a standard Two-Wire Serial Interface compatible with I²C protocols.
• Includes hardware write protection functionality controlled by the WP pin to inhibit write operations when tied to VCC.
• Features Schmitt trigger inputs and filter circuits on SCL and SDA lines to suppress noise spikes and ensure stable operation.
• Incorporates output slope control mechanisms designed to eliminate ground bounce during signal transitions.

Memory IC Applications

• Embedded systems requiring non-volatile storage for configuration parameters or calibration data.
• Industrial control applications operating within extended temperature environments.
• Low-power consumer electronics utilizing I²C bus architectures.

Memory IC Procurement Notes

Verify that the specific ordering suffix corresponds to the required temperature grade and package type. Confirm compatibility with system voltage levels, noting that this variant requires a minimum supply voltage of 2.5V. Ensure design adherence to the specified electrical characteristics for reliable operation at the target clock speeds.

Memory IC Selection Notes

Select this component for designs necessitating robust noise immunity and wide operational temperature ranges. The device supports page write capabilities to enhance throughput efficiency. Consider the availability of multiple package options if board space constraints vary, while ensuring the selected variant meets the specific voltage and thermal requirements of the application.

Memory IC Part Context

This part belongs to the 24XX04 family of serial EEPROMs manufactured by Microchip Technology. The family includes variants such as the 24AA04 and 24FC04, which differ primarily in supply voltage ranges and maximum clock frequency specifications. All members share the same fundamental architecture and interface protocol.

Memory IC Replacement Considerations

Direct substitutes include other 24LC04B series devices with identical pinouts and specifications, such as the 24LC04BT-I/ST for industrial temperature grades. Cross-manufacturer equivalents like the AT24C04 may require verification of timing parameters and voltage thresholds before implementation.
