AM625: MCU-Only Power Consumption Optimization

TI-CSC

Part Number: AM625

Hello E2E Experts,

In the MCU-only power measurements from app note SPRADG1 (54.91mW optimized), what was the M4F core frequency used? The note states 'slowed down the MCU Clock' but doesn't specify the actual frequency. Also, which specific optimizations were applied beyond default MCU-only mode entry?

Hello TICSC,

The M4F core PLL was bypassed meaning it dropped to 25MHz.

The other optimization was the unused IOs were put into a reset state which reduced the leakage current on each IO.

Best Regards,

Anshu
