Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AT24C08C-MAPD-T is determined by the following critical parameters:

• Memory capacity: 8Kbit with 1K x 8 organization
• Serial interface: I2C protocol compatibility
• Package form factor: 8-UFDFN with exposed pad, 2x3mm footprint
• Access time: 900 ns maximum
• Write cycle time: 5ms
• Supply voltage compatibility: Overlapping operational range
• Operating temperature range: Minimum -40°C lower bound
• Surface mount technology: Identical mounting method

The M24C08-RMC6TG from STMicroelectronics meets these substitution criteria. Both devices share identical memory capacity, I2C interface, package geometry, and critical timing specifications. Voltage supply ranges overlap within the 2.5V to 5.5V window. Both components maintain 900 ns access time and 5ms write cycle time, ensuring functional equivalence in I2C EEPROM applications.

Parameter Comparison

Engineering Selection Recommendations

Both the AT24C08C-MAPD-T and M24C08-RMC6TG are active production components with ROHS3 compliance and EAR99 export classification. The AT24C08C-MAPD-T carries AEC-Q100 automotive qualification, supporting applications requiring automotive-grade reliability. The M24C08-RMC6TG provides extended lower voltage operation (1.8V minimum) compared to the Microchip device (2.5V minimum), offering flexibility in low-power applications. The M24C08-RMC6TG operates at 400 kHz clock frequency versus 1 MHz for the AT24C08C-MAPD-T; both frequencies support standard I2C protocol requirements. The AT24C08C-MAPD-T supports higher operating temperature (125°C maximum) relative to the STMicroelectronics substitute (85°C maximum). Component selection should align with specific application temperature requirements and voltage supply constraints.

Frequently Asked Questions (FAQ)

Q: Can the M24C08-RMC6TG directly replace the AT24C08C-MAPD-T in existing designs?

A: Direct replacement is possible when application operating temperature does not exceed 85°C and supply voltage remains within 2.5V to 5.5V. Both devices share identical memory capacity, I2C interface, package footprint, and critical timing parameters. The lower clock frequency of the M24C08-RMC6TG (400 kHz vs. 1 MHz) does not affect I2C protocol compatibility.

Q: What are the package differences between these two parts?

A: Both components use 8-pin UFDFN packages with exposed pad in 2x3mm form factor. The AT24C08C-MAPD-T is designated 8-UFDFN, while the M24C08-RMC6TG is designated 8-UFDFPN. These designations represent equivalent package geometries suitable for identical PCB footprints.

Q: How do the voltage supply ranges differ?

A: The AT24C08C-MAPD-T operates from 2.5V to 5.5V. The M24C08-RMC6TG operates from 1.8V to 5.5V, providing lower voltage capability. Applications operating above 2.5V can use either device; applications below 2.5V require the M24C08-RMC6TG.

Q: What is the significance of the AEC-Q100 qualification on the AT24C08C-MAPD-T?

A: AEC-Q100 qualification indicates the AT24C08C-MAPD-T meets automotive industry reliability and quality standards. This certification is relevant for automotive and safety-critical applications. The M24C08-RMC6TG does not carry this specific automotive qualification.

Q: Are there differences in moisture sensitivity between these parts?

A: The AT24C08C-MAPD-T has MSL 3 (168 hours). The M24C08-RMC6TG has MSL 1 (unlimited). Lower MSL ratings indicate reduced moisture sensitivity and longer shelf life without desiccant storage requirements.
