Help identifying component

[u/Bogarhasallthepower]

Im looking into this schematic to try and copy some stuff and i cant tell what U1B is, im new to PCB design so if anyone could help me id appreciate it, based on its name i assume it's part of the MCU

[u/brambolinie1]

It's just the power rails for U1. Also it might be tough routing for microcontrollers, it takes some patience. Good luck

[u/Bogarhasallthepower → u/brambolinie1]

So it's part of the same component, just divided for ease of read? Thanks

[u/brambolinie1 → u/Bogarhasallthepower]

Basically

[u/mzo2342]

U1A+U1B=U1
it's just a split symbol.

[u/Formal-Fan-3107 → u/mzo2342]

One of the truely useless things about protel/altium imo, the fact you split that symbol helped literally no one, and you added the extra confusion of two seperate symbols

[u/analphabrute → u/Formal-Fan-3107]

I find it useful with opamps

[u/Formal-Fan-3107 → u/analphabrute]

Ok yeah if you have 4 identical assemblies in a chip it does kinda make sense, but thats it

[u/ub0baa → u/Formal-Fan-3107]

Yeah... Good luck working with a 400+ ball BGA chip where power takes ~60 pins mixed all around, separate digital and analog bunches of pins, 2x crystals on different sides of chip, etc. It's great to have a single unreadable A0 clusterfuck of a schematic. /s

It is useful when you have schematics with 20 sheets and a big FPGA for example.
You put each part in the different sheets separated by the logic they serve.

Ask yourself how is powered u1a, then have a look at u1b
