Part Number:AM3352
We have an existing AM3352 based product, containing 1.5V DDR3 SDRAM, which uses the TPS65910A3 PMIC. We also utilize the battery-backed RTC built into the TPS65910A3.
The 1.5V DDR3 is becoming more difficult to obtain, and 1.35V DDR3L SDRAM appears to be more plentiful. So we're thinking about changing to DDR3L. It appears the AM3352 supports DDR3L.
Looking at the TPS65910 datasheet, this PMIC doesn't appear to have an option for powering 1.35V DDR. Is that correct - am I reading that right? Is there a footprint-compatible part that does provide 1.35V for DDR3L? If not, what PMIC is recommended (ideally, one also containing a battery-backed RTC)?
Many thanks.
