LPC8xx deep power down errata

duaneallen — Thu, 05 Jan 2017 14:37:29 GMT

Has the problem of excessive power consumption during deep power down in the LPC8xx series been fixed, and if so, at what die rev level did that happen? The most recent errata document for this device family is rather vague about this.

Thanks

Hi Duane Allen,

Thank you for your interest in NXP Semiconductor products and the opportunity to serve you.

I'd like to know which chip you use and I was was wondering if you can upload the errat file you mentioned.

I'm looking forward to your reply.
Have a great day,

Here is the link to the (apparently) most current errata document for this device. Refer to section 3.2, thanks.

Hi Duane Allen,

The LPC82x series MCU don't have the kind of bug at all, however they need some specific requesting about the supply voltage.

Hope it helps.
