Substitute Part Grouping Explanation

Substitution of the ADSP-21469BBC-3 is determined by strict equivalence across the following critical parameters:

• Manufacturer and Series: Analog Devices Inc. SHARC® architecture
• Processing Type: Floating-point DSP
• Clock Rate: 400MHz
• Memory Configuration: 5Mbit on-chip RAM with external non-volatile memory support
• Voltage Specifications: Core 1.05V, I/O 3.30V
• Interface Set: DAI, DPI, EBI/EMI, I2C, SCI, SPI, SSP, UART/USART
• Package Specification: 324-BGA, CSPBGA (19x19)
• Operating Temperature Range: -40°C ~ 85°C (TA)
• Mounting Type: Surface Mount

The ADSP-21469BBCZ-3 meets all these criteria and is therefore a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The ADSP-21469BBCZ-3 is the direct substitute for the ADSP-21469BBC-3. Both parts share identical electrical specifications, memory configuration, interface capabilities, and physical packaging. The primary distinction is product status: the ADSP-21469BBC-3 is obsolete, while the ADSP-21469BBCZ-3 maintains active status with current manufacturing support.

The ADSP-21469BBCZ-3 carries ROHS3 compliance and REACH unaffected certification, providing regulatory alignment for new designs and production continuity. The packaging difference (Tray for ADSP-21469BBCZ-3 versus unspecified for ADSP-21469BBC-3) does not affect functional compatibility or PCB integration.
