Parameter Comparison

Engineering Selection Recommendations

The TMS320DM8167SCYG2 is the designated manufacturer substitute for the TMS320DM8167SCYG. Selection between these parts should be based on the following criteria:

Use TMS320DM8167SCYG when:

• Existing inventory is available and cost is the primary constraint
• Design has been validated specifically with this part number
• Product status as Last Time Buy is acceptable for the application lifecycle

Use TMS320DM8167SCYG2 when:

• New designs are being developed
• Long-term supply assurance is required
• Higher clock rates (1GHz DSP, 1.2GHz ARM® versus 800MHz DSP, 1.0GHz ARM®) provide performance benefits
• Active product status ensures ongoing manufacturer support and availability

Both parts maintain identical compliance certifications (ROHS3, REACH Unaffected) and mechanical/electrical specifications, ensuring direct substitution at the PCB level without design modification.

Frequently Asked Questions (FAQ)

Q: Can TMS320DM8167SCYG2 be used as a direct replacement for TMS320DM8167SCYG?

A: Yes. Both parts share identical package specifications (1031-FCBGA, 25x25), electrical characteristics (core voltage 1.00V, I/O voltages 1.5V/1.8V/3.3V), interface support, and operating temperature range (0°C ~ 95°C). The substitute features higher clock rates but maintains full backward compatibility.

Q: What is the primary difference between these two parts?

A: The TMS320DM8167SCYG2 operates at higher clock frequencies: 1GHz DSP and 1.2GHz ARM® compared to 800MHz DSP and 1.0GHz ARM® in the original part. All other specifications remain identical.

Q: Why is TMS320DM8167SCYG marked as Last Time Buy?

A: Last Time Buy status indicates the manufacturer is discontinuing this specific part number. The TMS320DM8167SCYG2 is the active replacement within the DM81x Video SOC series.

Q: Are there any PCB layout changes required when switching from TMS320DM8167SCYG to TMS320DM8167SCYG2?

A: No. Both parts use identical 1031-FCBGA packaging (25x25 footprint) and surface mount technology. PCB layout, footprint, and pinout remain unchanged.

Q: Do both parts support the same interfaces?

A: Yes. Both parts support identical interface sets: EBI/EMI, Ethernet, I2C, McASP, McBSP, PCI, Serial ATA, SD/SDIO, SPI, UART, and USB.

Q: What is the moisture sensitivity level for these parts?

A: Both parts have MSL 4 rating with a 72-hour floor life requirement. Identical handling and storage procedures apply to both part numbers.

Q: Are both parts RoHS compliant?

A: Yes. Both TMS320DM8167SCYG and TMS320DM8167SCYG2 are ROHS3 compliant and REACH unaffected.
