AT24C08D-UUM1B-T

Memory IC Overview

The AT24C08D-UUM1B-T is an 8-Kbit (1,024 x 8) I²C-compatible serial EEPROM manufactured by Microchip Technology. It operates within a supply voltage range of 1.7V to 3.6V and supports clock frequencies up to 1 MHz in Fast Mode Plus. The device features industrial temperature operation from -40°C to +85°C and utilizes a 4-ball Wafer Level Chip Scale Package (WLCSP). Key electrical characteristics include a maximum active read current of 1 mA and standby current of 0.8 µA.

Memory IC Feature Summary

• Supports bidirectional data transfer via a standard I²C-compatible 2-wire serial interface with integrated noise suppression filters.
• Provides hardware write protection through the WP pin for full array data security, though this feature is not available on the WLCSP package.
• Includes a Power-on Reset (POR) circuit to prevent spurious events during power-up sequences.

Memory IC Applications

• Industrial and commercial systems requiring low-power memory solutions
• Embedded controllers needing non-volatile storage for configuration data
• Portable devices utilizing limited supply voltage environments

Memory IC Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type and environmental compliance. Ensure that the selected variant matches the required operating temperature range and voltage specifications for your application design.

Memory IC Selection Notes

Select this component when a compact footprint is required due to its WLCSP packaging. Note that unlike other packages in the series, the WLCSP version lacks a dedicated Write-Protect pin, relying instead on software protocols or address configurations for data protection.

Memory IC Part Context

This part belongs to the AT24C08D family of 8-Kbit Serial Electrically Erasable and Programmable Read-Only Memory devices. The family offers various package options including SOIC, TSSOP, UDFN, and WLCSP to accommodate different space constraints while maintaining consistent electrical performance across the series.

Memory IC Replacement Considerations

Compatible substitutes include other AT24C08D variants such as AT24C08D-SSHM-T or AT24C08D-MAHM-E, provided the physical package dimensions and pinout compatibility are verified for the target PCB layout.
