AM625: Android Suspend-to-RAM Latency Measurement on AM625 / AM62P (Deep Sleep Mode)

Part Number: AM625
Other Parts Discussed in Thread: AM62P

Hello TI Team,

We are evaluating AM6254 / AM62P for an Android 16 based product.

From the AM62x TRM and Processor SDK documentation, we understand the supported low power modes include:

• CPU Idle (WFI)

• Standby

• Deep Sleep (Suspend-to-RAM)

• MCU-only mode

While documentation explains the architecture of Deep Sleep and DDR retention, we could not find Android-visible suspend/resume latency numbers.

We are looking for measured values (preferably from TI EVM or reference Android BSP builds) for:

1. Active -> Deep Sleep transition time
   (From Android suspend request to system in Deep Sleep)

2. Deep Sleep -> Resume time
   (From wake event to Android framework fully responsive)

Assumptions:

• DDR retained in self-refresh

• Standard TI Android BSP

• Display enabled

• No cold boot involved

Specifically:

• Typical latency range in ms?

• Example PM: resume complete after _ms logs?

• Is sub-500 ms resume achievable in standard SDK?

• Any known constraints with display or peripheral drivers?

We would appreciate any official validation numbers or lab measurements available.

Thank you.
