AT24C04N-10SI-2.7-T

Memory IC Overview

The AT24C04N-10SI-2.7-T is a 4-kbit (512 x 8) serial electrically erasable programmable read-only memory (EEPROM) manufactured by Microchip Technology. It operates within a supply voltage range of 2.7V to 5.5V and supports a maximum clock frequency of 100 kHz at this voltage level. The device utilizes an 8-lead JEDEC SOIC package and is designed for industrial temperature ranges from -40°C to +85°C. Key electrical characteristics include a maximum write cycle time of 10 ms, a standby current of up to 4 µA, and a maximum active read current of 3000 µA.

Memory IC Feature Summary

• Features a bidirectional 2-wire serial interface with Schmitt triggers and filtered inputs for noise suppression.
• Includes a dedicated Write Protect pin that enables hardware data protection when connected to VCC.
• Supports 16-byte page write modes with partial page write capabilities and self-timed internal write cycles.
• Provides high reliability with one million write endurance cycles and 100-year data retention.

Memory IC Applications

• Industrial control systems requiring low-power non-volatile storage
• Commercial applications necessitating small form factor memory solutions
• Embedded systems utilizing I2C bus communication protocols

Memory IC Procurement Notes

Verify the specific ordering suffixes against official Microchip documentation to confirm package type, operating temperature range, and voltage specifications. Ensure compatibility with system voltage levels and bus timing requirements before integration. Confirm RoHS compliance status through manufacturer datasheets or certificates of conformity.

Memory IC Selection Notes

Select this component for designs requiring 4-kbit capacity with I2C connectivity in space-constrained environments. Consider the 100 kHz speed limitation at 2.7V operation when designing high-speed data logging applications. Evaluate the 8-lead SOIC footprint constraints against available PCB real estate and thermal management needs.

Memory IC Part Context

This part belongs to the AT24C01A/02/04/08/16 family of serial EEPROMs. These devices are optimized for low-power and low-voltage operations in industrial and commercial settings. The family shares common interface protocols and organizational structures, differing primarily in memory density and address pin configurations.

Memory IC Replacement Considerations

Compatible substitutes within the same family include AT24C04N-10SC-2.7 and AT24C04N-10PC-2.7, provided the package style matches the design requirements. Cross-manufacturer equivalents may require verification of voltage tolerances and timing parameters.

Memory IC FAQ

How many devices can be addressed on a single bus using the AT24C04?

Four 4K devices can be addressed on a single bus system using the A2 and A1 hard-wired address inputs.

What is the function of the WP pin?

The Write Protect (WP) pin provides hardware data protection; connecting it to VCC disables write operations to the array.

Does the AT24C04 support partial page writes?

Yes, the device allows partial page writes, enabling updates to specific bytes within a 16-byte page without overwriting the entire page.
