Substitute Part Grouping Explanation

Substitution of the ATSAM4CMP16CB-AUR is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Identical core processor architecture (ARM Cortex-M4/M4F)
• Matching core configuration (32-bit dual-core)
• Identical operating frequency (120MHz)
• Equivalent program memory capacity (1MB FLASH)
• Matching RAM size (128K x 8)
• Identical supply voltage range (1.62V ~ 3.6V)
• Same I/O pin count (52)
• Identical peripheral set (DMA, LCD, PWM, WDT, Brown-out Detect/Reset, POR)
• Matching connectivity interfaces (EBI/EMI, I2C, IrDA, SPI, UART/USART)
• Equivalent data converter specifications (A/D 6x10b)

Mechanical Equivalence Criteria:

• Identical package type (100-LQFP)
• Matching package dimensions (14x14mm)
• Surface mount mounting type
• Identical pin configuration

Compliance Equivalence Criteria:

• RoHS3 compliance
• Matching moisture sensitivity level (MSL 3)
• Identical operating temperature range (-40°C ~ 85°C)

The ATSAM4CMP16CC-AUR meets all substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The ATSAM4CMP16CC-AUR is a direct functional and mechanical equivalent to the ATSAM4CMP16CB-AUR. Both devices share identical electrical specifications, peripheral configurations, and package characteristics. The primary distinction is product lifecycle status: the ATSAM4CMP16CB-AUR is obsolete, while the ATSAM4CMP16CC-AUR maintains active production status.

Both parts comply with ROHS3 standards and carry identical moisture sensitivity classifications (MSL 3). The substitute part is suitable for new designs, legacy system maintenance, and production continuity applications where the original part number is no longer available.

Selection of the ATSAM4CMP16CC-AUR eliminates obsolescence risk and ensures access to current manufacturing support and supply chain availability.
