Home of the 8051 Experts

While we have designed products with microcontrollers from Motorola, National Semiconductor, NEC, Hitachi, Oki and others, our expertise and focus lies with the venerable 8051 family.  We have been designing on, in, with and around the 8051 since 1979.  There is nothing about the 8051 that we don't know.

So if you need an 8051 project completed or an 8051 problem solved quickly and correctly, email us at info@pentaena.com.  We'll provide you with a plan to get to your goal.

Or if you're just curious about some aspect of the 8051, be it historical or technical, send us an email.  We'd be happy to answer your questions.
